Signal Jammer Frequenies for Brazil

Mobile communications in   Brazil are  pretty well developed. But it can be said not about the whole   country,  because north western regions lack not only mobile   communications,  but even basic stationary land line phones. That's a   pretty common  problem for countries of Latin America, for example Mexico has the same issues with communications in mountain regions.


Major mobile carriers here   are TIM,  Claro, Vivo and Oi. We should also mention the fact that TIM   and Vivo  are the only nationwide mobile carriers, while Claro operates   in all  states except Amazon basin states. Oi is not nation wide too and   their  services are limited.


But the biggest carrier on   the  Brazilian market is TIM. It's telephony network is nationwide and is    based on the GSM technology. That company has a range of almost 94% of    Brazilian urban population and is available in 3203 cities. All the    carriers in Brazil provide a mobile internet access based on GPRS and    EDGE technologies. EDGE technology is available in 79% of GSM covered    area of the country.

All of those carriers   provide GSM  services and GSM standard in Brazil is similar to US and   Canada. It  uses 900/1800 MHz frequencies to  transmit voice calls and   text  messages, so if you are planning to visit this country and have a   GSM  900/1800 mobile phone it will be really convenient to purchase a   local  SIM card. As you can see Brazil uses so called European GSM   standard  and if you a traveling for the US – your mobile device won't   work in  their networks.


3G service is also presented   in  this country and it works with a most widely spread 2100 MHz    frequency, but  TIM provides both 2100 MHz and WCDMA, that uses 850 MHz    for 3G. Mobile Internet is available mostly in big cities, the  coverage   in rural areas is pretty weak and sometimes even unavailable.  But 3G   market grows pretty fast in Brazil, it is pretty obvious  because the   share of 3G enabled smartphones sold in Brazil grows and  in 2012 12   million of 3G enabled devices were sold here.


Another reason of such fast   market  growth is the fact that mobile communications are rather cheap in    Brazil, but on the other hand, roaming is very expensive, so if you are    a tourist – make sure to buy a local SIM card, they are sold free  here.   Also we should admit that 3G Internet access is available to 54%  of   urban population of Brazil.


And now a couple of words   about 4G.  Brazil is building its 4G network now and it will be launched   soon.  Now major mobile carriers are getting licenses for broadcasting at   4G  frequencies. 4G coverage will probably be available on the same    territory, where 3G is presented.


As we have already mentioned   Brazil  has rather poor coverage in a sparsely populated areas, but all   those  four major carriers provide mobile services for almost 98% of the    Brazilian population. As a short conclusion we ca say that mobile    communications grow pretty quickly in Brazil and most of the problems    with mobile coverage are caused by the lack of investment and low    populations in some areas.
