1. Product overview

The WALRUS is the outdoor gateway(should with box protection) Gateway with

professional

specifications quipment with 2 receiving channels. Several thousands end nodes around

the

gateway can communication. And gateway with a sensitivity of -138 dBm and a maximum

power of 500 mW you can easily reach the most distant nodes. No technical skills are

needed to operate this device. Just plug it in and you are connected to all the things around

you.

3. Key feature

3.1 Distance

Maximum connection distance is ~10km in open terrain, buildings and metal structures do

hinder the transmission. Experience learns that distances of 3-5km are realistic if the

gateway is mounted on a (high) point with free sight.

3.2 Nodes handle

10-20 thousand is a theoretical maximum, under the assumption that nodes only send once

per hour. Due to collisions, resend packets, packet loss etc, the number of nodes that can

effectively be handled is lower, typically 8 thousands.

3.3 Update

If any update or parameter setting on the gateway, no need to field operation, software

remotely control can be used.

3.4 Hoc network

Once the device installation, no need to link the device with gateway, device can select the

gateway which with the better signal intensity.
