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.
VTrans technologies developed and patented by C reatcomm, utilizing a series of
advanced technologies such as TDMA, intelligent rate control, Auto AC K Time-out Adjust,
having the advantage of long transmission range, high date rate and robust transmission.
VTrans technology solves the problems of hidden-node problem in the 802.11 network
infra-structure. 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
devices, and adjust the wireless parameters to achieve the best link quality.
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
clients demand different throughput. If the client demands higher throughput, its priority
level can be set to H igh, otherwise set to Low. W hen the client demands the same
throughput, their priority level can be set to the same level.
N ote: W hen using TDMA mode, the TDMA button need to be enabled at AP devices in
the web-based configuration menu. The devices from other vendors cannot be connected
to TB2I in the TDMA mode. W hen TDMA is enabled, your phone or laptop cannot be able
to connect to the device.
Auto AC K-Timeout Adjust
：
It is suggested to enable this function, so that the distance
between 2 devices can be detected and all the related parameters can be optimized to
achieve the best link quality.
