network at any one time. Under this mode, both PTP and PTMP are available. It is highly
recommended to use this mode when the distance between two nodes is less than 20KM.
Peer-to-Peer (TDMA): The EZBackhaul connects to another wireless device within the same
networking program using TDMA protocol. TDMA divides each cellular channel into multiple time
slots to increase the amount of data that can be carried, hence increase the throughput. Under this
mode, only PTP is available and is suggested to use when the distance between the two
EZBackhaul is greater than 20KM.
Base Station ID (SSID)
For Base Station mode, it requires SSID for CPU clients to associate with. This wireless network
name is shared among all associated devices in your wireless network. Keep it identical on all those
devices. Note that the SSID is case-sensitive and can not exceed 32 characters.
Wireless Mode
The
EZBackhaul can only communicate with wireless devices of 802.11a.
Channel/Frequency
Channel varies much as the available band differs from country to country. Select a proper operating
channel in the drop-down list according to your situation. To avoid adjacent channel interference, it
is highly suggested to set separate of the 2 RF links as far as possible.
Transmit Rate
Usually “
Best” is preferred. Under this rate, the EZBackhaul will automatically select the highest
available rate to transmit. In some cases, however, like where there is no great demand for speed,
you can have a relatively-low transmit rate for compromise of a long distance.
Output Power
Specify the signal transmission power. The higher the output power is, the wider the signal can cover,
but the power consumption will be greater accordingly then. Usually “
100%” is preferred.
Band Width
Four levels are available: 5MHz, 10MHz, 20MHz and 40MHz. Among them, 40MHz can enhance
the data rate more effectively, but will take more bandwidth, thus cause possible interference.
TDM Coordination
Stands for “Time-Division Multiplexing technique”, this resource reservation control mechanisms can
avoid packet collisions and send the packets much more efficiently allowing for higher effective
throughput rates.
