There are two competitors in the industry worldwide mobile phone networks, GSM and CDMA. CDMA (Code Division Multiple Access) is working in the United States through Verizon Wireless. GSM (Global System for Mobile Communications), slightly more than his opponent, and he developed a GPRS (Global package) technology. GPRS is increasingly becoming very popular because of its affiliation to GSM. Most network services in the U.S. using this technology. In fact, about 80% of the global market for mobile phones to connect via GSM, because that is the most common standard.

As a result, the popularity of GSM », organizing trade was founded, the Association of GSM, including mobile operators and handset manufacturers around the world. The GSM Association estimates more than 4.3 billion people in over 212 countries is a GSM-users. This technology is designed 2G mobile phone systems (second generation), which makes it possible to store more data in the system of data exchange. GSM is also developing new methods of rapid communication across the world via short message system (SMS). GPRS technology soon became the EDGE (Enhanced Data rates for GSM), a fast way to transfer data. The greatest advantage of GSM technologies mature GSM network is more stable, its users less signal damage in the building, type of network used in all parts of the world making roaming more affordable.

The main difference between GSM and CDMA technology is the fact that GMS does not allocate all the frequencies of end users, they are separated by a time interval for the more efficient use of bandwidth. CDMA uses digital modulation called spread spectrum and frequency available to users, create a unique code for each user, bandwidth allocation. It works by distributing the voice data through the channel. After reaching the end-user information is added, as well as puzzles and decipher.

Most cell phones have the right BlackBerry for CDMA technology, which makes data transfer faster, even though many of them work with EDGE. The problem is that the two technologies are incompatible, because they are very strong competitors. So, if you’re working with a cell phone CDMA, and you travel outside the U.S., you may have problems with the network. If your BlackBerry works with GSM, it should be OK, because most countries except the United States adopted the technology to GSM. In such cases, the best thing you should do is talk to your provider.
