The Technological Difference In Mobile Phones

Estimated read time 2 min read

Mobile Phones is handheld electronic devices that are capable of transmitting voice signals over wireless networks. There are three major types of mobile phones: CDMA, GSM, and UMTS. A CDMA mobile phone, CDMA only, cell only, or UMTS, sometimes shortened to just cell or just mobile phone, can only make and receive calls on a radio frequency code through a wireless carrier system while the user is within their phone service area. The best examples of a CDMA mobile phone are AT&T models. Other good examples are Verizon and Sprint models. To make sense of all that go to King Communications and a Vodafone store near me

The GSM mobile phone uses a Global System for Mobile Communication (GSM) code to identify itself and to establish connections. It transmits GSM signals by radio. Some GSM phones have a data port that allows additional memory storage and data transmission. CDMA mobile phones have a single frequency, which is used for voice and data transmissions. CDMA phones cannot receive or send any data.

Finally, the UMTS (Unified MMS) mobile phones have a single assigned frequency and allow connection with other devices that use the same frequency. Generally, these are more expensive than CDMA phones because they are difficult to operate, especially for new users. However, this type of mobile phone has the advantage of being able to link with a Bluetooth device, an infrared camera, a PDA, or a laptop. In addition, they can also link to a Global Positioning System unit.
