4.3.3 Collocated Radios
When the radio network’s master device is located too close to another radio device, communications between all devices
is interrupted. For this reason, always assign a unique Network ID to your wireless networks. The Network ID (NID) is a
unique identifier you assign to each wireless network to minimizes the chances of two collocated networks interfering with
each other. Assigning different NIDs to different networks improves collocation performance in dense installations.
4.3.4 Be Aware of Seasonal Changes
When conducting the initial Site Survey, the fewest possible missed packets for a given link is better. However, seasonal
changes may affect the signal strength and the total signal quality. Radios installed outside with 50% missed packets in
the winter months may have 80% or more missed packets in the summer when leaves and trees interfere with radio re-
ception.
A good signal in winter doesn't always mean you will get the same signal strength the rest of the year.
During spring and summer, leaves may block more of the radio signal.
4.4 Basic Remote Antenna Installation
A remote antenna system is any antenna system where the antenna is not connected directly to the radio; coaxial cable connects the
antenna to the radio.
When installing a remote antenna system, always include a lightning arrestor or coaxial surge suppressor in the system.
Remote antenna systems installed without surge protection invalidate the warranty of the radio devices.
