Fragment Threshold: It means the size of each frame. If it is set to 256 bytes and the size of data

block is 1024 bytes, the data block will be divided to four frames to send.

RTS/CTS Threshold: RTS is a flow control mechanism to prevent collision between 802.11b

and 802.11g mobile stations to send data to the access point in the same time. CTS is another

flow control mechanism to prevent collision when two mobile stations, who do not know the

existence of each other, send data to the access point in the same time. RTS and CTS are used

for point-to-multipoint bridge application and they are enabled when the threshold set to 2347.

Super bridge mode provides 3 mechanisms to improve the bridge throughput:

• Compression: Frame is compressed by hardware before transmitting. Note that the

compression may save bandwidth but would consume frame process time. In case the

data is already compressed (e.g. mpeg frame), please do NOT turn on this function.

• Bursting: Turning on Bursting function enables multiple frames are transmitted at SIFS

intervals which may reduce transmission overhead. But this may increase packet error

rate on the other side.

• Fast Frame: Turning on Fast Frame function enables two Ethernet frames bundled into

a single wireless frame.

Warnings 1: It is required to setup the same options of Super Bridge Mode between

local AP and remote AP to communicate properly.

Warnings 2: It depends on which mode the associated clients run in to decide whether

turning on Bursting and Fast Frame function or not.

4.14.5 Remote Bridge Configuration

The MAC address of the remote AP should be added into the field MAC Address, and the

remote AP should add the MAC address of local AP to form a bridge. Moreover, all bridging

equipments including both local AP and remote APs should be set at the Same Radio

Frequency.

4.14.6 Bridge Security

By enabling Bridge Security in the 5GHz Configuration, as shown in Figure 26, users can input

an encryption key for the bridge. Note: if the Local AP and Remote AP mismatch the encryption

type or encryption key, there will be no link established by 5GHz radio. Please make sure the

security parameter setting at the both ends of the bridge.
