KWJ-WSN Wireless Range Extender Principle of Operation
On power up, the range extender will locate a gateway that has the
“best” wireless signal available. The device then auto-configures itself
to communicate and link with this gateway. After linking with the parent
gateway, it then establishes itself as a sub-network with it’s own dedicated
channel to the gateway, relieving congestion from multi-sensor networks.
Delays Associated with Using Wireless Range Extenders
Data coming from a sensor is delivered to a range extender and forwarded
onto the gateway. In all implementations where network traffic is kept
below 6 messages per minute, the worst-case lag through a range
extender to the network is 20 seconds. If more than 6 messages are gen
-
erated by wireless sensors talking through a range extender, it is possible
to experience data lag beyond 20 seconds.
KWJ-WSN Wireless Range Extender Features
• Extends the coverage area of your wireless sensor network.
• Supports 6 messages / minute.
• Built in memory can queue up to 30,000 messages for delivery to
the gateway.
• AC powered, so no batteries needed.
* Important
- If the range extender is unplugged or loses power, all
sensor messages stored on the device will be lost!
