The lowest cost mobile telecommunication system and wireless access system in the world.
Igm2000 IP GSM system combines GSM networks with IP networks, the two most widespread and lowest cost networks around the world. It means that a wireless communication networks can be set up and spread though IP networks quickly, easily and lowest cost. Based on IP softswitch and IP telephony technology, igm2000 IP GSM system is the newest generation GSM mobile communication system over the world.Using maturity and steady IP and GSM technology and depending on its lowest cost, there are broad marketplaces to establish GSM networks over IP networks or to expand GSM networks boundless through IP networks. IP GSM system can be use extensively in telecom infrastructure, wireless access system, urgent communication, mine and oil field communication, enterprise wireless communication and other areas. IP GSM system can be connected with PSTN or other telecom networks over SIP, ISDN PRI protocol.
- Base on IP softswitch and IP telephony technology, base stations of GSM system are connected using IP connection, so the cabling cost can be save.
- GSM network can be connected to traditional PSTN network over SIP, ISDN PRI, SS7 protocol.
- Using GSM phones as mobile terminals, the terminals do not need to be made specially, so it is lowest cost.
- Support all GSM features, include SMS.
- IP GSM system is a green communication system. Because the power of its base station is equal to 25% of general public GSM base station, the electromagnetic radiation of base station and cell phone can be reduced down to the lowest level, and the standby time of cell phone is extended.
- It is easy to install and set up using IP cabling structured system to connect the GSM base station.
The VoIP GSM Gateway- HG-1600 series comes with 8 GSM VoIP ports for connecting IP-based systems with GSM networks. The VoIP GSM Gateway is designed to provide a cost-effective alternative for fixed-to-mobile or mobile-to-fixed telephone calls for small and medium businesses.
