TDMA
C urrently, most of the outdoor bridge products are developed based on 802.11 protocols,
however, it has the limitations of short-distance, hidden node problems, and poor point-to-
multi-point performance.
The VTrans technology developed and patented by C reatC omm, utilizing a series of
advanced technologies such as TDMA, 5M/10M/20M/40MH z bandwidth support,
intelligent rate control, Auto AC K Time-out Adjust, having the advantage of long
transmission range, high date rate and robust transmission.
TDMA technology solves the problems of hidden-node problem in the 802.11 network
infra-structure. 5M/10M/20M/40MH z bandwidth can be flexibly configured by the uses in
different working scenario to achieve the best link quality. Intelligent rate control algorithm
can be adapted to quick channel quality variations, while stabilize the wireless throughput,
thus suitable for long-distance transmission. AC K Time-out Auto Adjust can automatically
detect the distances of the TB5F devices, and adjust the wireless parameters to achieve
the best link quality.
The TDMA setting is shown in the following Figure 14.
Figure 14 TDMA setting
To use the TDMA, the user needs to enable TDMA mode in the AP device, and set a
priority level in the station device. W hen several stations are connected to one AP, different
stations demand different throughput. If the station demands higher throughput, its priority
