Networks

A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other.

GSM

GSM (Global System for Mobile Communications) was developed to replace the analog cellular network (1G), therefore it is referred to as a 2G mobile network. It has been improved with the addition of General Packet Radio Services (GPRS) and later via the Enhanced Data rates for GSM Evolution (EDGE) technology.

GSM 850 MHz
GSM 900 MHz
GSM 1800 MHz
GSM 1900 MHz
CDMA

CDMA (Code-Division Multiple Access) is a channel access method for communications within mobile networks. Compared to other 2G and 2.5G standards like GSM and TDMA, it provides increased data transfer speeds and allows more subscribers to connect simultaneously to the network.

CDMA 800 MHz
TD-SCDMA

TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is a 3G standard for mobile networks. It is developed as an alternative to the W-CDMA standard in China by the Chinese Academy of Telecomunications Technology, Datang Telecom and Siemens AG, and combines TDMA and CDMA.

TD-SCDMA 1880-1920 MHz
TD-SCDMA 2010-2025 MHz
UMTS

UMTS stands for Universal Mobile Telecommunications System. Based on the GSM standard, it is deemed as a 3G mobile network standard. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology.

UMTS 850 MHz
UMTS 900 MHz
UMTS 1900 MHz
UMTS 2100 MHz
LTE

LTE is deemed to be the fourth generation (4G) of mobile communications technology. It has been developed by the 3GPP based on the GSM/EDGE and UMTS/HSPA technologies in order to increase the speed and capacity of wireless data networks. A further development of the technology is called LTE Advanced.
