Enables rapid TD-SCDMA network deployment for operators
Signs order from major base station vendor

(2 August 2007, Hong Kong) – Comba Telecom Systems Holdings Limited (“Comba” or the “Group”, Hong Kong stock code: 2342), a leading wireless enhancement solutions provider, announced today the availability of its TD-SCDMA Remote Radio Unit (RRU) solution for China’s 3G Market.   The RRU is a fiber fed radio that extends the coverage of base stations, yet maintains an extremely small footprint.  With the Chinese telecoms market bracing itself for 3G licensing, Comba’s RRU solution will play a key role in helping the rapid roll out of TD-SCDMA networks.

At the same time, Comba also signed a supply contract with a launch customer and announced that it has received an initial order for the new TD-SCDMA RRU from a major TD-SCDMA base station manufacturer.   With a total value in excess of USD 1 million, Comba’s RRU is being deployed in 3G network trials within China.
 
Typically deployed in combination with base stations, Comba’s RRU enables operators to roll out TD-SCDMA networks effectively and rapidly whilst maximizing capacity and coverage.  With up to 30 percent cost savings, the RRU deployment solution compares favorably to the traditional approach of a pure base station network buildout.

Featuring one of the market’s smaller remote units, the RRU can be deployed in difficult-to-reach sites in a variety of formations to suit different coverage requirements without signal degradation.  For example, a series of RRU may be deployed in linear formation to enable TD-SCDMA networks along a highway, or in a matrix formation to cover a city block.

Developed in-house by Comba’s research and development division in Guangzhou, the RRU complements Comba’s portfolio of TD-SCDMA solutions that ranges from tower mounted solutions and repeaters to complete in-building coverage systems that have already been deployed in numerous 3G trials throughout China.
 
Comba’s Chairman and President, Mr. Tony TL Fok said, “We are delighted to announce the availability of our new Remote Radio Unit solution for TD-SCDMA band. We are working closely with our customers in ensuring that the RRU contributes to the success of the TD-SCDMA trials”.  He further added, “When an announcement of 3G licensing in China is made, we are positive the Comba RRU will play a key role in enabling the roll out 3G networks quickly and effectively across the region”.
