Seamless mobile connectivity at up to 350 kilometers per hour

(15 September 2008 Hong Kong) Comba Telecom Systems Holdings Limited ("Comba" or the
"Group", Hong Kong Stock code: 2342), a leading wireless enhancement solutions provider,
announced it has successfully delivered and installed a wireless enhancement solution for China's
Beijing-Tianjin Intercity Rail. This solution is the only platform that serves all on-train wireless voice and
data services for the passengers.

With a 120 kilometer line connecting Beijing to Tianjin, railway trains run at an operational speed of up
to 350 kilometers per hour, making it the fastest train service in the world. Travel time between these
two cities has now been shortened to 30 minutes.

Although speed is the greatest advantages of a high speed railway, it is also poses challenges in the
provision of ubiquitous mobile communication coverage. To overcome this, Comba's solution included
the division of the line into a number of sections and set up of over 120 service spots along the route.
Comba's advanced fiber transport remote radio solution then boosts and enhances wireless reception
whilst minimizing signal interference and extending reach.

Mr. Tony TL Fok, Chairman and President of Comba, said We are pleased to supply our wireless
solutions to the Beijing-Tianjin Intercity Rail. The result of exhaustive testing and standby support
means that passengers can enjoy seamless coverage on their mobile phones. Moreover, Comba's
solution is easily scalable and upgradeable to 3G standards should it be required. He further added
Our experience and track record in the provision of wireless solutions for transport networks is
unsurpassed where solutions have been implemented for the Tibet-Qinghai railroad and Shenzhen
subway for example. This latest project is testament to our customers' faith in the company's solution
and services.
