TDMA technology solves the problems of hidden-node problem in the 802.11
network infra-structure. 5M/10M/20M/40MHz 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. ACK Time-out Auto Adjust can automatically detect the distances of
the DH-PFM880 devices, and adjust the wireless parameters to achieve the best
link quality.
The TDMA settings 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. When several stations are connected to one
AP, different stations demand different throughput. If the station demands higher
throughput, its priority level can be set to High, otherwise set to Low. When the
stations demand 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 both AP
and station devices in the web-based configuration menu. The devices from other
vendors can not be connected to DH-PFM880 in the TDMA mode.
5 Status
Status is the first page shown after logging in. It shows the current configuration
and real-time monitoring of the device, seen in the following Figure 15. This page
is divided into 2 parts: Status and Monitor.
