Some information about Mobile GSM bands
GSM is the most popular standard for mobile phone service in the world. In more than 200 world countries who use GSM mobile phone services. However, different countries use different radio frequencies for their GSM mobile networks. Worldwide four frequencies are widely used for GSM mobile services. Are 850MHz, 900MHz, 1800MHz and 1900MHz.
Although 850, 900, 1900 and 1800 have been very nearby, usually phones can not receive more than one frequency at a time, a phone that works with a band, can not receive signals from other bands. So if you want your phone to work with several bands, multiband phones need. Based on your needs, you can go to your dual band, triple or Quad set.
Frequencies, high and low has some advantages and disadvantages. For the high-frequency service, the network is carried out, at least, influences of the time. And you can have clear and uninterrupted link. Another advantage of the high frequency is that you only need a small antenna. main disadvantage of the frequency band higher is its limited scope. These bands are good for cities where the density of mobile users is more. When, as the lower frequencies are good for rural areas due to its wide range.
850 MHz is the lowest frequency used for GSM mobile services. As a result, 850 MHz network has a greater and more widespread, then get to 900, 1800 and 1900 MHz Moreover, the difference between 850 MHz and 900 MHz barely perceptible. services less often are good at building large because of their greater penetrating power. A disadvantage of low-frequency network is its low capacity.
900 MHz networks, the networks are very old. At 850 MHz, 900 MHz also is broad in scope and more pervasive after 1800 and 1900 MHz
1800 MHz is a relatively high frequency for cellular phones. Because of this, 1800 MHz has a smaller and less penetrating reach compared to 900 MHz and 850 networks. To reach this large buildings is low. One advantage of 1800 MHz is that the capacity is higher. This band is inactive for the cities where the density of mobile users high.
1900 is only available in North America MHz, some networks in Canada and South Africa This item is not available in Europe or Asia. 1900 MHz to 1800 MHz quite similar. Due to the high frequency of 1900 MHz is not interrupted by bad weather and you may have a connection most cases clear. For this network, a provider of GSM antennas using more mini. One advantage of 1900 MHz is that the capacity is higher.

Is Your Cell Phone Bugged?
April 14th, 2010
This short video explores ways to determine if your cell phone has been compromised to act as a bug. While it’s obviously unlikely that this would happen to most people, it was recently revealed that the FBI has used this technique, and just as illicit wiretaps are possible, illicit cell phone bugging could also occur. This video is based on Lauren Weinstein’s December 2006 blog entry: “How To Tell If Your Cell Phone Is Bugged” located at: lauren.vortex.com Be seeing you!

How Mobile Phones Work
April 3rd, 2009
Working Of Cell Phones
Cell phones, which operate on radio frequency, cover compartmentalized cell like areas with the help of base stations. Learn more. It’s truly amazing when you think how far we have come in the technology of cellular phones.
Cell phones or cellular phones are so called as they cover compartmentalized, cell like areas. The origin of the Cell phone can be traced back to the year 1973 when Motorola came up with World`s first cellular portable telephone which was commercialised as Motorola DynaTAC 8000X.
These days, new cell phones are being added at a rapid pace. The parts of them typically consist of following: circuit board; antenna; keyboard; LCD – liquid crystal display; battery; microphone; speaker.
In recent times, they are available with a wide range of functions. To list a few functions, depending on the type of cell phone you choose: store contact information; keep track of appointments; set reminders; prepare to-do lists; send/receive e-mail; play games; send text messages (sms); access to internet; watch and enjoy TV; built-in calculator; integration with other devices like GPS receivers, MP3 players, etc.
Cell phones, operating on radio frequency, have come up with an innovative cellular approach to counter limited availability of RF spectrum. Now, several cell phone towers are used to cater to a large geographic area.
Each tower (base station), covers a circular area called a cell. A large region is split into a number of cells allowing different base stations to use the same channels/frequencies for communication. This enables thousands and thousands of mobile telephone users to share far fewer channels.
Another important aspect is that, phones need less power to transmit to reach any base station as each base station covers a smaller area. Reducing the required transmit power reduces the size of the battery and thereby the weight of the phone. This has led to miniaturization of cell phones which would not have been possible without the cellular technology.
When you use your cell phone, following things happen. First the phone locates base station having strongest signal, and requests for a channel assignment. The base station permits channel assignment and the call gets accepted. The call is then forwarded to the local telephone network if it is to a regular phone otherwise it is transmitted through the cellular network. The call is then sent to its destination through the telephone network.
When the cell phone is switched on, SID (System Identification Code) on the control channel compares it to the SID programmed into the phone. If the SIDs match, the phone understands that the cell is communicating with home system. The phone sends a registration request, along with the SID and the MTSO keeps track of the phone`s location in a database. If the SID on the control channel does not match the SID of your phone, then the phone is in roaming.
The three technologies commonly used by 2G cell phone networks for transmitting information: frequency division multiple access (FDMA); time division multiple access (TDMA); code division multiple access (CDMA).
GSM (Global System for Mobile communications) implements TDMA, to connect to the specific service providers in different countries. GSM uses subscriber identification module (SIM). SIM stores all the connection data/identification numbers needed to access a particular wireless service provider.
Standard 2.5G protocols used widely are GPRS, EDGE to name a few. Some latest 3G protocols are: Universal Mobile Telecommunication Service (UMTS); Wideband Code-Division Multiple Access (WCDMA); High-Speed Downlink Packet Access (HSDPA); Evolution Data Maximized (EVDO).
A few popular cell phone models in the market have been offered by Nokia, Ericsson, Motorola, Samsung, LG, etc. with each model with its own range of collections.The year 2008 may be a high watermark in the cell phone history with Nokia N-Gage 2, HTC Dream, Apple iPhone 2, BlackBerry Touchscreen, Sony PlayStation Phone which are expected to be launched.

Now that we’re settled in the house, we’ve noticed that our mobile phone reception is quite poor. We both work at home quite often and use our mobiles when we do, so have been looking for a mobile phone signal booster.
Cellular phones from the early 1990’s are considered second generation (2G) and they were able to work on mobile phone systems such as GSM, IS-136 (TDMA) and IS-95 (CDMA). Digital mobile phone networks were in use in the United States.

Comparing GSM Cell Phones to CDMA Cell Phones
December 30th, 2008
Gsm Vs Cdma Mobile Technology
GSM and CDMA network technologies are the two main competing technologies set up by cellular service providers across the globe.
GSM is an abbreviation of Global System for Mobile Communications, while CDMA is an abbreviation of Code Division Multiple Access
The technology:
Mobile communication systems have to make use of the microwave frequencies above 800 MHz for transmission and reception of the signals. Different service providers operate in pre allocated frequency bands given to them by the international standards. Below listed are the methods to access these microwave frequencies.
FDMA (Frequency Division Multiple Access) – FDMA puts each call on a separate frequency.
TDMA (Time Division Multiple Access) – TDMA assigns each call a certain portion of time on a designated frequency.
CDMA (Code Division Multiple Access) – CDMA gives a unique code to each call and spreads it over available frequencies.
GSM is a global standard based on TDMA.
How these technologies affect the common man:
In case of GSM:
If you opt for GSM technology, you have the freedom to choose handset separately from the wide variety of big handset companies like Nokia, Motorola, Sony Ericsson, etc who retail their products in the market.
You can then purchase a SIM card from any of the GSM service providers like Hutch, Airtel, etc and insert it in to your handset and start talking.
You even enjoy the freedom to switch the service provider and still continue with the same handset.
GSM service providers are well networked globally. Therefore it offers much better international roaming. You must check for roaming call rates and coverage in the regions or countries where you visit frequently.
Another major benefit that GSM users enjoy is that if you travel to other countries you can make use your same GSM cell phone there too( if it is a quad-band phone 850/900/1800/1900 MHz). To save yourself from roaming charges from your service provider, you can purchase a local SIM card with call value and a local number in the country you are visiting.
In case of CDMA:
Here the handset is network locked. You have to buy a complete package from the service provider that includes both, the handset and the connection (prepaid / postpaid).
Two main CDMA players in India are Reliance and TATA.
Earlier it was difficult for Reliance users who wanted to retain the same number but wanted to change their reliance handsets, to do so. However now it is possible by making use of the handset change card that is available in a nominal amount.
TATA however made it very user friendly. Due to its T – SIM enabled handsets; it is easier for TATA users to change their handsets
Reliance and TATA now have a range of entry level, mid-segment and features rich advance handsets available with them. However in this case the choice of handsets is limited to the models offered by the Service Provider.
You cannot change the service provider and still keep the same handset.
Voice clarity in CDMA network is supposed to be better as it uses same frequency across all cells.
Here you need to check for International roaming tie ups if you travel abroad frequently. You do not enjoy the freedom like GSM mobiles.
TATA is soon launching T-SIM to enable international roaming with one world one number concept.
Before choosing a CDMA or GSM Mobile phone from any mobile store, you need to understand the features and services provided by these mobile phones well

GSM Cellular Phone – 6 Powerful Must Have Benefits GSM Cellular Phones have been around since the early 1990′s. It is only recently that consumers have reaped the benefits of this new technology. Read on to learn more.
By design, the method of transmission for a GSM Cellular Phone is through Global System for Mobile (GSM) communication. Although this system was recognized in the past, it had been first employed on a commercial basis only back in 1991. Nowadays, most of the cell phones throughout the world use the GSM.
Because GSM utilizes the TDMA digital technology, the possibility exists to have up to three voices in one slot in contrast to the analog cell phones where only one voice had the ability to go into one slot. The GSM technology can do so because it utilizes digital compression along with its in-built encryption characteristic. Therefore, even in the event that the space used is the same, there will be more usage capacity.
There are numerous benefits in employing the GSM Cellular Phone for which it owes its amazing global popularity. Some of the most prominent advantages are itemized below:
1. You have the ability to use it as a SIM card – You can get a lot of freedom with the Subscriber Identification Module or the SIM card. You can gather all kinds of information on this chip and then utilize it in whatever other mobile set as and when you change it. The other kinds of sets do not offer this type of freedom to you.
2. Surpassing quality of sound – because the GSM Cellular Phone utilizes technology that is digital in nature, it allows the filtering out of every unnecessary background noises, thus leaving a loud and clear voice transmission for outstanding communication.
3. High Security – There is integrated security for the GSM Cellular Phone that no seperate telephone system has available without specifically requesting it. Therefore, you have the complete assurance that your two way conversation is both safe as well as secure at all time, and at anyplace without costing you any extra money.
International Options
4. It makes available international roaming capabilities – the GSM Cellular Phone can quite easily link up and associate to other international digital providers and thus furnish you with the independence of utilizing your cell phone even when you travel internationally abroad. Although the calls are somewhat costly, customers are happy to utilize this facility because it is hard to communicate to everyone of their new numbers as and while they travel.
5. Extended talk time – the digital technology provides a great deal longer talk time because the battery is utilized in the best practical way. This is additionally increased by the fact one can administer more than one call at any given time.
6. GSM Cellular Phone Extra Options – this kind of cell phone has the ability to incorporate Camera, MP3, FM radio etc., which makes this phone an outstanding entertainment gadget in addition to the useful accessory that it is.
