We offer mobile telecommunications services principally using the Global System for Mobile Communications, or GSM, standard. GSM is a pan-European mobile telephone system based on digital transmission and mobile telecommunications network architecture with roaming capabilities. Each of our GSM networks consists of:

• Base stations, which are transmitters and receivers that serve as a bridge between all mobile users in a cell and connect mobile calls to the mobile switching center.
• Base station controllers, which connect to, and monitor and control, the base station within each cell, performing the functions of message exchange and frequency administration.
• Mobile switching centers, which are central switching points to which each call is connected, and which control the base station controllers and the routing of calls.
• Transmission lines, which link the mobile switching centers, base station controllers, base stations and other telecommunications networks.
• Software applications that drive the mobile telecommunications infrastructure. We have the right to use a total of 39 MHz of spectrum, for transmission and reception, respectively, in the 900 MHz frequency band and the 1800 MHz frequency band in Mainland China.

We have a refined GPRS network. General Packet Switched Radio Service, or GPRS refers to the application of packet-switched technology in wireless telecommunications which will only consume network resources during data transmission without the need to have a dedicated channel for continuous data transmission flow. GPRS technology allows mobile subscribers to transmit and receive data at a speed exceeding 115 kbit/s.

3G is the acronym refers to the third generation mobile communication technology. The first generation simulation relative standard cell phone (1G) and second-generation GSM, TDMA digital mobile phones (2G). 3G mobile phones generally, refers to wireless communications and multimedia communications such as the Internet generation mobile communication systems integration. It can handle images, music, video and other forms of media, including web sites,telephone conference e-commerce and other information services. To provide this service, the wireless network must be able to support different data transmission speed, in other words, in a room, outdoors and the environment to travel separately to support at least 2 Mbps (megabytes / a promotion ?84kbps per second (1,000 words Festival / per second) and the transmission speed wir eless.
