The upgraded link is supported by the CB-Access broadband wireless access system. It consists of an Access Point (AP) and a Subscriber Unit (SU), mounted on the rooftop of the Chow Yei Ching Building and the Yam Pak Building respectively. The AP and SU communicate with each other through a wireless channel with a speed going up to 25Mbps. Both the AP and SU are connected to the building's network via a 10-BaseT Ethernet connection.
Our benchmark tests have shown that the upgraded link yields a sustained average throughput of 3.5 Megabits/s*, which represents more than six-fold increase from the performance before the upgrade.
Network users in the Yam Pak Building should be able to notice a significant
increase in network transmission speed in accessing the facilities and
resources on the Campus Network and Internet.
