SMS and MMS Integration With VoIP Communications

There are a great number of people even in developing countries who have, in one way or another, experienced using SMS or Short Message System using mobile phones. In fact, when people hear the word SMS or Text message, most would readily associate the term with mobile phones. An extended standard in messaging called MMS or Multimedia Messaging Service is similar to SMS except for the added capability of sending not only text messages but audio, video and pictures as well.

SMS and MMS has been a profitable element in the mobile business, with major networks registering more than 150 billion text messages and 4 billion MMS for each quarter of the year. Research show that teens in the United States send an average of more than 100 text messages on a daily basis – more than the daily emails sent by office workers on the average. This is the primary why operators continue to support SMS and MMS features in their networks.

With the ever growing popularity of VoIP or Voice over Internet Protocol systems and networks, it would only be logical to expect the same SMS and MMS features to be available in this telecommunication infrastructure. With the reduced cost of sending voice and data communication packets via the internet in these systems, the use of SMS and MMS over the VoIP network will be more appealing than ever.

Why Use SMS/MMS in the First Place?

The use of mobile phones has grown rampant over the years and even people from developing nations don the latest mobile phones and gadgets. One of the main reasons why this phenomenon has grown to such magnitude is the SMS feature built-in into their mobile networks — a cheap and very convenient way to communicate while on the go from practically anywhere. This is a great alternative means of communication to spending considerable airtime costs through direct phone-to-phone calls.

Service providers on the other hand are using these SMS/MMS facilities as an added service for their subscribers as a way of maintaining loyalty. As mentioned earlier, the volume of SMS/MMS messages sent on a daily basis proved that it is definitely a very viable cash cow for these operators. On top of that, the SMS/MMS facilities can be a great marketing tool for new products, services and offers without falling into the spamming category.

Sending SMS/MMS through VoIP Networks

With VoIP networks and Internet Telephony Service Providers slowly moving into mainstream telecommunications, the added feature of SMS/MMS messaging capabilities will surely be a required service by most subscribers. With multi-protocol facilities for VoIP networks which include the H.323, SIP and most recently the 3G standards, sending SMS/MMS messages will likely become more efficient than ever.

Several VoIP providers have already jumped into place and added SMS/MMS capabilities within their networks, with very affordable pricing models inclusive of call time. Affordable mobile VoIP solutions will also be marketed and integrated into these services, adding a more mobile experience for VoIP users as well as including compatibility with existing cellular networks. These mobile VoIP phones will likely be packed with features similar to standard mobile phones, which include colored displays, cameras, e-mail, phonebooks and SMS/MMS facilities.

The Value of Written Communication

Have you ever stopped to consider the value associated with written communication? While our society has become so driven by the visual and the verbal, it is written communications that provide daily direction to us as individuals and to our society as a whole.

Consider these elements of value provided by written communication:

• Written communications INFORM. Would you be pleased to know that the pilot of your jetliner is going over the preflight checklist from memory? Or the pharmacist is ignoring your physician’s orders and guessing which medicine you require? Or your employer failing to notify you in writing of an important change in your medical benefits? Obviously, we need written communications to provide information and facilitate understanding. We read newspapers, books, and magazines. We decide on what to eat from reading a menu. We make purchases based upon written specifications and reviews. With the veritable explosion of information now available to anyone with an internet connection, we can become informed on virtually anything/everything.

• Written communications PROVIDE CLARITY. While any form of communication can be confusing or ambiguous, as a general rule written communications provide more clarity than verbal instructions. Written communications, as opposed to the verbal form, can be referred to repeatedly if one’s memory is less than stellar. Presidents send our armed forces to war with written orders. Military commanders develop plans and issue their own written orders. Rules of engagement are provided in written form to combatants. Clarity is typically better served in writing.

• Written communications PROVIDE A BASIS FOR AN ORDERLY SOCIETY. Our laws are developed, interpreted, and communicated to citizens in written form, from Supreme Court decisions to posted speed limits to search warrants. Our public entities and private companies publish written codes of conduct to establish standards of acceptable behavior. Our games are guided by written rules of play (imagine how players and fans would react if game officials ad-libbed the rules and the home team lost!).

• Written communications are TIMELESS. Moses didn’t rely on his memory for the Ten Commandments. We have the documents of our nation’s history-the Constitution and Declaration of Independence, Lincoln’s Gettysburg Address, Eisenhower’s message on the eve of D-Day-that are preserved and revered in their written form. Letters we write to friends and loved ones are saved and appreciated for years, perhaps even generations.

Surely you’ve heard the phrase, “Put it in writing.” So often, the written form of communication is the most effective way to educate and inform. There is indeed often great value in “putting it in writing.”

Get Your Ex Girlfriend Back By Using The Method Of Opening The Lines Of Communication!

As you know that getting an ex girlfriend back is not an easy mission. If you really do want to get her back, then you need to know how to take the right step in order to achieve what you want. What is the right step I'm talking about? Well, you should be able to know how to open up the lines of communication with her.

It is very possible that poor communication between the two of you is considered to be the real reason behind the break up. In addition, this is also considered to be the root cause for many broken relationships out there.

If you want to get an ex girlfriend back by trying to open the lines of communication with her as stated, then honesty should be your best policy. Remember, trying to get her back by using dirty tricks is not going to help. Even if you can get her back by using those tricks, but she will break up with you again, sooner or later.

However, you really need to be patient in order to try this honest communication method with your ex girlfriend. Just keep in mind that once you can communicate with her, then it is very possible that your situation will keep getting better.

In addition, in case that the problem in your relationship took a long time to develop, then you should understand that it will take some times to get it fixed. Even you can open the lines of communication with your ex girlfriend, but do not expect that things will get better overnight. However, if you can communicate with her, then you are considered to be on the right path to get an ex girlfriend back. At least, you are trying to fix the problem in the relationship and you need to make sure that the same problem will not happen again.

Plastic Cellphone Accessory Markups Create Drastic Profits

For a brief period in my younger days I worked temporarily for an importer of cheap Chinese goods. Indeed, I was completely amazed at the markup of some of the plastic things we import, so cheap in fact, I used to pull them apart just to look at what was inside, after all, I could buy some of these items for around a dollar. I remember pulling apart a little cigarette adapter for a cell phone. I was blown away how cheaply it was made, yet how good it looked on the outside. It worked, worked well, but there was nothing to it.

Buy 1,000 at a time and your price was $.89 and if you buy 100 still only $1.19 and yet, they sold retail for about $15.99 as an impulse item – talk about a mark-up, wow. Okay so, let’s talk shall we?

While I was in the car wash business we used to have such items in the lobby of the car wash for business folks who needed them. At that time cellphones were new and the minutes were costly, not like today, thus, only business people really had them, as they could justify the cost, and yet, they still made their phone calls as brief as possible, and some had cellular phone bills of well over $800 per month.

Today, the quality of these small accessories hasn’t gone up much, although I’m sure they are a little better due to rules and regulations and UL ratings. The price too isn’t very much more than they were back then. The markups are still unbelievable, so there is plenty of money available in that deal. In fact if you offered a small business owner who was selling a cell phone accessory device a mere five dollars, their markup would still be 100%, and that is paying one-third the normal price. So even with all the inflation over the years, and the loss of the value of the dollar, folks that sell plastic cell phone accessories still have incredible markups that truly create intense profits.

It is amazing how valuable information is in this day and age – those that know where to get boxes of these types of items can make a killing, and all those little cell phone stores that can sign you up for service with one of the larger carriers, you wouldn’t believe how much money they make on all those accessories, or how much in bonus they’re willing to pay the sales people were able to get you to buy these items on impulse. Please consider all this and think on it.

Installation of a Cell Extender

There are many names for an indoor cell extender. Commonly it is referred to as Cell Booster but in actual fact it is a fully functional low powered cellphone repeater. The industry refers to it as a mini, a pico or a SOHO repeater or a cell extender. There are indoor and outdoor types. There are different formats like CDMA, GSM, DSC, UMTS There are also combinations of the mentioned frequency formats and they are referred to as dual & even tri-band repeaters. All repeaters should be considered as the network operator's responsibility. The network and the frequency spectrum is their licensed property over which they supply specific services and for which the end user pays revenue. The quality of equipment used on these networks is their responsibility as well as to provide coverage through. Installations of any kind should be transported out by a fully qualified network technician or an appointed contractor.

Should a residence or business not have indoor cellphone coverage, their preferred network operator whose services have been assigned to be referred to prior to making such a decision? Only if this service is not forthcoming due to whatever reason, should a resident consider installation of an indoor cell extender.

• It must be remembered that this devise is an indoor repeater and has been designed to provide signal coverage indoors.
• Coverage within homes, lodges, storerooms, workshops, factories, shoppingalls, basements, offices, tunnels, all fall under the category of indoor coverage.
• These systems are not for repeating signal over any distances outdoors, but with use of multiple antennas and line amplifiers, large indoor or secluded arias can enjoy converge.
• Even though it is an indoor device it still needs to be installed by a qualified installer.
• Even though cell boosters are obtainable over the counter as a DIY kit it is austerely advised that you do not purchase one and try to install it yourself.

Before a cell extender is installed, have the RSSI (Received Signal Strength Indication) measured. This is done by a trained installer measuring the RSSI using a portable mast, high quality cable and antenna. This is achieved and the measurement is done using a portable spectrum analyzer, a portable signal strength meter or software used on a lap top or cell phone. Full signal may be indicated on your mobile, but no coverage is available from the network you need to connect with, so also determining which operators' signal is being measured is also relevant.

The RSSI is vendor dependent – in other words, the network being connected to can fluctuate, it can improve of deteriorate. BTS output power levels can be changed or an antenna can be turned a little into another direction, the network could intercept another BTS (Base Transmitting Station) or cellphone tower in the vicinity. A building or a bridge could have been built in between the BTS and the home or business shielding it totally. Because high frequencies are LOS (Line of Sight) dependent, these factors can change and individuals can be affected drastically. All these factors should be measured and recorded.

The RSSI measurement should be done at a height of not less than 7 meters from the ground. This is the minimum installation height of an outdoor antenna on a cell extender. Ground level RSSI is irrelevant for this purpose. It is imperative that you do have some signal on the site of installation – if there is no signal there is nothing to amplify. But, no signal at ground level does not mean there is no signal, there could be good signal just above the tree line.

What must be achieved? These measurements are curtail in determining what the outdoor (donate or up / link) gain should be. How many BTS towers in the coverage aria and their situation is information needed in selecting the correct antenna type to communicate between the BTS and the repeater. This criteria is not catered for in DIY kits. Antenna types, their radiation patterns and their strength (Gain) are not common knowledge to the layman. Once this is established, a link budget calculation can be calculated and the correct cell extender recommended. This will ensure a cell extender that does what it is designed to do and that is to give you indoor coverage. Incorrect calculation and unqualified installation will very likely lead to a system that oscillates, creates noise on the network and gives very limited coverage.

Typical signal strength evaluation One bar signal on you cell phone can be amplified to full strength with a cell extender. Signal strength is measure in dBm. Here is a rough guideline that could assist. Remember, this is what the user is experiencing at ground level. He may have full signal on a hill 100 meters from home.

5 Bar = -40-80 dBm very good
4 Bar = -85 dBm good
3 Bar = -90 dBm usable
2 Bar = -95 dBm may break up and drop calls
1 Bar = -100dBm poor

Theoretically using a Coiler TG900 27dBm cell extender with 60dB gain and selected antennas a site with -90dBm can be amplified to -27dBm which will provide coverage to a normal sized home. Between 7 ~ 10met radius on the GSM900 frequency is common. Much larger coverage arias have been achieved regularly but one designs to be very careful in sketching coverage when RF is being applied as it is not very predictable and so many variations apply.

Is it usable signal? There are weak signals, poor quality signals, noisy signals, reflected signals etc. The parable applies "garbage in, amplified garbage out". The better the RSSI before amplification, the better the coverage and the quality of the amplified signal. By reflected signal we mean the signal is bounced off a stationary object such as a mountain cliff or a building such as a silo etc. These signals are not always stable. Often this signal is varying in strength. Reflected signal can be amplified, but the repeater will not need to destabilize the violating signal.

Which Network Operator's signal is being amplified? Network Operators in SA often use the same infrastructure but many rural high sites host only one operators BTS. It is necessary therefore to ensure that the relevant base station provides the operator's service subscribed to. The broadband GSM repeater amplifies the whole GSM900 frequency spectrum and the other operator's signal is also amplified. This can mean that the user could have excellent operator 2 signal but weak operator 1 signal. The Service Providers / Network Operators use band selective transmitters and receivers (BTS) to control their own customer's billing and added services. This means only that operator's dedicated channels in the frequency spectrum will be enhanced and not their oppositions. This also assists them in identifying who is responsible when a problem arises.

Which services are amplified? By services we refer to:

• GSM900 (Global System for Mobile Communications) – voice, GPRS and 2G (2nd Generation) in SA
• GSM1800 or DCS (Digital Cellular Service) used for EDGE (Enhanced Data rates for Global Evolution) – Data and high density arias for voice in SA
• UMTS2200 (Universal Mobile Telecommunications System) commonly uses W-CDMA (Wideband Code Division Multiple Access), for 3G (3rd Generation) or HSDPA (High-Speed ​​Downlink Packet Access)

Because each of these technologies is being run on a specific frequency band, a repeater for that bandwidth or combination repeater engineered for two or more bandwidths is needed to enhance each format. GSM900 on the 900MHz frequency, DCS on the 1800MHz and UMTS on the 2.1GHz frequency. South Africa operates a Tri-Band network in its major suburban areas where all three services are available. In rural and minor suburb arias a dualband (GSM900 & DCS) or a singleband GSM900 & GPRS network should be available. The UMTS cell extender can not amplify 3G if the local BTS is not a UMTS carrier even if the end user's mobile is 3G enabled. He will have to be satisfied with GPRS or Edge.

Why is all signal not available in all arias? No network available. A network is rolled out according to a network plan. Services for arias are planned for and provided according to the potential market. The network operator is a business with shareholders all demanding the best dividends on their investments. A BTS to provide these services to the end user will not be authenticated for one or two farmers with the potential to generate R6000pm calls / sms's made by themselves and their workers. Where there is substantial inhabitancy of an aria a market for network services is created and accordingly coverage will be provided.

No coverage even though network is available due to distance. Approximate distance a frequency travels when generated at prescribed power level. (DBm power ratio in decibels) What is not commonly understood is that different frequencies have different wave lengths and are transmitted at different power levels as determined by the governing broadcasting body. The power level is determined due to the danger of Radio Frequency Radiation (RF) hazards. 1800MHz is already a low microwave frequency and 2.1 GHz is close to the 2.4GHz frequency most microwaves ovens operate on. Should this frequency be amplified indiscriminately, a real health hazard will be inevitable. Should you fall outside this radius you will experience weak signal.

No coverage even though network is available due to obstacles.
• A second point not commonly known is that the higher the frequency (the narrower the wave length) the more difficult it's penetration of obstacles, like trees, buildings, steel structures like roofs and hills etc.
A suck of the thumb indication over an obstacle-free field (LOS or line of site)
• GSM900 (900MHz) transmitted from a BTS should give a coverage distance / radius of 16km
• DCS1800 (1800MHz) transmitted from a BTS should give a coverage distance / radius of 7km
• UMTS (2200MHz) transmitted from a BTS should give a coverage distance / radius of 3km

3G and HSDPA have a lot of challenges in the cities centers due to penetration. Eg Accompany could have great 3G connectivity – then a bridge, a building or the Gautrain overhead rail is built across the up-town suburb between the BTS and your point of reception, and that is the end of the 3G signal. One only needs to move offices down the hall to lose a 3G signal and this is due to the penetration phenomena.

What should become clear is that it is no easy task giving coverage to every person in a diverse country such as South Africa. It is even more of a challenge to provide all the service available with cellphone technology coming up with new formats and medias such as "push technology" and video conferencing. It is not only about the phone but about the signal.

If need assistance, do not talk to just anyone. Talk to the right people.

Information System and its Trends

Information System and technologies have become a vital component of successful businesses and organizations.

Information System means an interconnected set of information resources under the same direct management control that shares common functionality. A system typically includes hardware, software, information, data, applications, communications and people, while an information system is the arrangement of people, data, processes, presentation of data and information technology that supports our everyday needs. It is actually technologically implemented medium for recording, storing, and disseminating linguistic expressions, as well as drawing conclusions from such expressions. The computer technology is used for implementing information systems.

TYPES OF AN INFORMATION SYSTEM

Information System can be divided in two basic forms

1. OPERATIONS SUPPORT

SYSTEMS

It is further subdivided into
The following

O Transaction Processing System (TPS)

O Enterprise Collaboration System

O Process Control System

2. MANAGEMENT SUPPORT

SYSTEM

It is further subdivided into the following

O Management Information System (MIS)

O Decision Support System (DSS)

O Executive Support System (ESS)

TOOLS FOR THE DEVELOPMENT OF AN INFORMATION SYSTEM

The steps which are involved in the development of an Information System are:

Analysis, Feasibility Study, System Design, Testing, Implementation, Documentation.

TRENDS IN INFORMATION SYSTEM:

It is generally accepted that information is a vital commodity for the successful operation of today's organizations. Nowadays modern business organizations are using computerized information systems in order to obtain desired information. However, as the technology advances rapidly the main issue is how can an organization should effectively use such an information system which its management sometimes can be unpredictable in order to effectively help the whole organization structure to improve and take the most out of it.

It seems fairly obvious that Information systems have played an important linking role even before the advent of the Internet. Thus, for example, the possibilities offered by Information systems have strongly influenced the way managers were able to exercise control and therefore constituted an important factor in the organization of large-scale enterprise and their geographical extension. The same is true for governments and their statistical instrument. The recent integration of computer networks and electronic data exchange facilitated the creation of common databases and policies among Governments, speeding up developments, which had started earlier. It also created new possibilities for business, for example enabling companies to develop new organizational practices (eg just-in-time).

However, the role of Information systems in the organization is shifting to support business processes rather than individual functions. The focus is outwards to customers, rather than inwards to procedures. Businesses are changing more and more quickly.

This poses a challenge to existing Information systems, which are often inappropriately structured to meet these needs. It also poses a challenge to the people who design, work and use these systems, since they may hold outdated assumptions.

To ensure the services provided by Information systems whenever needed and their failure will not cause catastrophic disaster their reliability and efficiency becomes extremely important. Imagine what would happen when a banking system malfunctions due to some critical faults in the system or when a healthcare information system provides wrong advice for patients.
It is even not over-saying that our lives are already under control of computer systems but their reliability and efficiency has become extremely important

APPLICATIONS OF INFORMATION SYSTEM:

There is a wide range of applications of information system that are implemented in today's world. To name a few such as

1. Sales analysis, production performance and cost trend
Reporting system

2. Product Pricing, profitability forecasting and risk
Analysis system

3. Sales and inventory processing and accounting System

4. Geographic Information systems

5. Health Care Information Systems

6. Banking Information System

7. Petroleum Refining System

8. Power Generation System

9. Steel Production System

The Perpetual Inventory System: The Good and Bad

Inventory management is needed in order to keep track of a company’s goods and services. If you do not know what you have in stock and what products you are selling, then you have no way of maximizing your profits. When it comes to controlling inventory, there are two main systems that can do it. They are the perpetual and periodic inventory systems. The difference between the two is basically the manner in which they are updated. But, for the purpose of this article, we will concentrate on the perpetual system.

With the perpetual system, the inventory is always updated. Whenever an order is placed, received or shipped, the corresponding product will be updated in the system at that exact moment in time. This is mostly possible due to technological advances that allow computers to be updated in real time. When product is received, it is put into the system via bar coding technology. The perpetual inventory system is extremely popular because all retrieved and delivered information is up to date and in real time. You are guaranteed that the information that that is received within the reports is the most up to date information available.

However, if there are any mistakes, it is usually due to human error. The information is only as accurate if it is entered into the system. It cannot be seen, analyzed or corrected if it is never keyed into the system. This is why it is important that all orders are handled at the time that they are placed, received or shipped.

Of course with any type of system there are going to be both pros and cons. Other than real time updating, one of the main benefits of using the perpetual inventory control system is that it is a time saver. For instance, if sales personnel must know how much inventory is in stock before they can sell it to potential customer. This is especially true if the customer is expecting same day delivery. With a perpetual system, a salesman can check inventory stats on his laptop or mobile phone. He has the information that he needs at his fingertips. It is a smart way to check inventory before placing a same day order for a customer and finding out that the product is not in stock.

In the past this one little task would have involved calling someone in the company to check to stock levels. Many times this would have meant sending someone out to the warehouse in order to do an actual physical count of the inventory. Depending on the company and how well it is organized, a simple task like this could take hours to complete. This is why the perpetual system is used by plenty of companies. It saves time by always being consistently updated.

When it comes to the perpetual inventory system, there are few cons. The main complaint is that it requires a hefty investment on the front end. The software for this type of system is not cheap. However, most companies find the system very beneficial, once the software has been purchased and installed. Secondly, as stated throughout this article, the system has to be constantly updated. A lot of information has to be consistently feed into the system in order for it to work properly.

As you can see, the perpetual system has both pros and cons, but it is a very good inventory management system to have.

How to Get a Cell Phone Contract With Bad Credit

As a former employee of a cell phone carrier I found that many consumers are skeptical of purchasing a cell phone due to their undesirable credit history. They often believe that prepaid is their only option but they would prefer a contract provider. Many people do not realize that even with subprime credit they may still be eligible for a mobile phone contract. 80% of the customers with the misconception that they can not get a contract were often surprised when they received approval for a cell phone plan. If you have bad credit and prefer better quality cell phones over prepaid then here are a few steps you can take to get a contract phone.

Pay a down payment

Many customers with bad credit may be asked to pay a down on their contract. The price can range from $ 50 to $ 400 depending on the carrier. You get the money back with interest after waiting two years. Go through the application process to find out what you qualify for. If your down payment requirement is at the low end then go for it but if it's at the high end then move on.

Apply with various carriers

If you're preferred cell phone carrier is charging you a very high down payment then apply at another company. Some carriers pick up customers that their competitors may reject. Its amazing how one carrier may classify you as a high risk but another may consider you to be a prime client.

Go with credit lenient companies

Not all cell phone companies use the same process for credit checks. Each company has different standards and requirements than there competitors. It's been my experience that Sprint and T-mobile usually provide great deals for customers with bad credit.

Sprint's credit requirements are the lowest of the major US carriers. Many customers who were returned by other carriers almost always get a contract with sprint. Usually they ask for a $ 50 down payment but may be up to $ 150. Sprint has some of the lowest priced service plans in the nation that helps to keep monthly bills to a minimum.

T-mobile is also a good choice for customers with low credit scores. In addition to having low credit requirements, T-mobile takes it a step further by vanquishing down payment and providing account options form customers for subprime customers. The first of two options is called the even more plan. In this plan the customer still has the ability to purchase phones at a discount price but they have to pay the first month's bill up front. Activation fees are automatically washed, saving you a large sum of money if you purchased more than one phone. The second option is the even more plus plan. This option is a no contract plan. You have to pay full price for the phones but the monthly fees are cheaper than the even more plan. After a year of timely payments on the even more plus plan T-mobile will review your account to determine if you're eligible to upgrade to a contract plan.
