Section 2 How WiPry Works
2.25 Undo / Relocate Hardware
Convenient setup of the AWG/Router is often in a basement or mechanical room far
away from where wireless internet is used. This can be a problem because the signal
strength will attenuate (or lose strength) as it travels further away from the source. So
when should the AWG/Router be relocated to a more central location? If the Signal to
Noise (SNR) ratio is too low. The industry minimum is 25 dBm for VOIP and video
streaming. Here’s how to duplicate the setup shown below:
Step #1 In the spectrum menu option, make sure either Real Wave is selected or Both.
Step #2 Both SNR and SINR are calculated automatically for you in the top right corner
of the screen.
Step #3 Industry best practices to have at least 25 dBm of SNR. However, factoring in
the SINR is also very helpful as it factors in the current interference (the “I” in SINR) at
that moment. SNR calculates just the signal strength compared to the noise floor. It
doesn’t factor in interference. Using the SINR is an even better metric for evaluating the
environment. For even better results, require 25 dBm SINR for any real time applications
(like VOIP or video streaming).
VOIP over a cell phone (especially on 2.4 GHz) is a challenging request. Customer
could improve telecommunications by hard-wiring VOIP box (like an OBi)
directly into the router. Using a cordless phone with this setup yields a
far superior experience for the customer AND the AWG/Router would
not need to be relocated.
