Antenna Pattern Width
Based on the 5GHz 8db Omni-directional backhaul antenna, the width (Height) for the
node to cover with-in the antenna pattern from the mesh link node is shown in table below.
It's a guideline to consider of the height offset among adjacent Mesh nodes. For example,
for mesh nodes deploy within 100m apart, their height offset must be within 10.5m.
However because of the reality of no way to be 100% sure that Omni antenna is placed
perfectly perpendicular to ground, always consult professional antenna engineer for the true
deployment.
Note: A different spec Antenna will have different distance require to the ground. This
information is based on the standard 5GHz 8db Omni-directional antenna.

Tx Power/Range/Link Speed
Wireless link distance has to do with TxPower (transmitter output power), free space path
loss, antenna gain, antenna cable loss, signal quality (EVM), and SNR. Below are some
information related to the calculation of distance of deployed wireless link of ArrowSpan
MeshAP product.
