World's largest network set for China

CHINA's two main suppliers of analogue cellular systems, Motorola and Ericsson have signed up with China's Directorate General of Telecommunications to provide roaming between China's various cellular networks.


The resulting interconnected system will be the world's biggest nationwide roaming network, according to Motorola.


The interconnection, scheduled for completion by the end of the year, will link more than 3 million customers in 26 provinces.


Roaming requires special switches and software that allow cellular networks to recognize customers from another region.


No value of the contract was given. Earlier this year, Motorola completed the installation of equipment to interconnect all of its cellular telephone switches in China.


The networking project will use the North American standard known as IS-41, Motorola said.


This protocol, developed by Motorola, allows users of one vendor's system to roam to another's.


'Motorola is committed to open network architecture and IS-41 is an important step in the advancement of such a non proprietary interface,' said Richard Sell, vice president and general manager of Motorola's Cellular Infrastructure Group.


Motorola set the stage for the roaming deal earlier this year when it completed the interconnection of its cellular systems in China, creating the world's biggest contigous Total Access Communications System (TACS) network.


So far, the company has networked over 140 EMX mobile switches for nationwide roaming.
