RF Interference
The WGLA switch and WPMM radio operate in the 2.4 GHz range. Upon initial pairing with the WGLA switch, the
WPMM’s radio will automatically scan each of the 16 channels in the 2.4 GHz range and choose a channel with the
least amount of usage. This provides a level of protection from RF interference as the chosen channel where RF
communication is low will have a lower chance of signal collision.
However, if multiple RF sources exist in the chosen channel or the external source has an extremely high power
intensity or it is in close proximity to the Limitless™ Series antenna, RF interference can cause an RF signal to not
reach the WGLA switch or WPMM monitor. RF interference can be caused by many sources (i.e., other radios in the
same operating range, solar activity, high frequency digital products, conventional microwave ovens, etc.). If the
Limitless™ Series is in an environment with a high usage of products in the 2.4 GHz range, or the RF environment
is unknown, an on-site RF survey may prove to be valuable in identifying possible RF interference sources along
with other existing wireless devices.
Once the RF sources are identified and located, it may allow the Limitless™ Series antennas to be moved away
from the identified RF sources to achieve acceptable performance. The other option is removing the external
source, if feasible.
