PHONES WITH GSM AND CDMA CODE

Fortunately, cell phone signal boosters can help solve those problems. Sometimes we experience slow speeds, dropped calls, and poor signal due to the distance between your phone and the closes cell tower, or building material blocking the signal's path. For that reason, new cell phone technology, such as GSM, CDMA, UMTS, TDMA, and LTE, are developed to optimize the use of the frequency bands that have been allocated for cellular use.Д®ven though these technologies are designed to improve network capacity, reduce latency, improve data speeds, and provide us with better signal, they are not perfect. ItвЂ™s important to note that the majority of the spectrum has been allocated for something. The radio frequencies mobile devices use to transmit information are part of the electromagnetic spectrum, which is allocated by the FCC and NITA. The tower then forwards the information to a switching center or control center to connect you to the internet or the user you are trying to reach. These waves travel from your phone to the nearest cell phone tower thatвЂ™s provided by your carrier. Why are Cell Phone Technologies Important?Д¬ell phones use radio frequency waves to make calls, send text messages, browse the web, and stream videos. Universal Mobile Telecommunications System (UMTS)- A cell phone standard used to define the third generation of GSM mobile communication.Time Division Multiple Access (TDMA)- A method used to manage the users accessing a frequency channel on TDMA-based networks.Long Term Evolution (LTE)- A cell phone standard used to define the fourth generation of mobile communication for GSM and CDMA networks.Global System for Mobile Communications (GSM)- A cell phone standard used to define the second generation of mobile communication.Evolved High Speed Packet Access (HSPA+)- A mobile broadband technology used to provide the UMTS network with high-speed internet.Evolution Data Optimized or Evolution Data Only (EVDO)- A mobile broadband technology used to provide the CDMA2000 network with high-speed internet.Digital Advanced Mobile Phone Systems (DAMPS)- The second-generation successor to AMPS.
