User Manual of DS-3WF01C-2N
VAP Isolation: The device supports multiple VAP; if this feature is enabled, and when
the client1 is connected to VAP1, the client1 will not be able to communicate the client2
which is connected to VAP2.
TDMA：
Currently, 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.
XTrans technologies developed and patented by HIKVISION, utilizing a series of
advanced technologies such as TDMA, intelligent rate control, Auto ACK Time-out
Adjust, having the advantage of long transmission range, high date rate and robust
transmission.
XTrans 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. ACK 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. When 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 High, otherwise set to Low. When the client demands the
same throughput, their priority level can be set to the same level.
Note: When 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 DS-3WF01C-2N in the TDMA mode. When TDMA is enabled, your phone
or laptop cannot be able to connect to the device.
Auto ACK-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.
