Interference Detection And Avoidance; Tips To Improve Wireless System Performance; Setting The Access Point Country And Region (Mxcwapt-B And Mx- Cwapt-W Only) - Shure Microflex MXCW Manual

Interference Detection and Avoidance

The access point has a built­in spectrum analyzer that continuously scans the wireless environment and ranks the best chan­
nels for operation. MXCW commonly operates in a specific block of 5 GHz channels that require Dynamic Frequency Selec­
tion (DFS) or Doppler weather radar Dynamic Frequency Selection (DDFS). These channels reserve priority for weather,
aviation, and military devices.
To avoid interference from priority devices, DFS channels are scanned for 1 minute and DDFS channels are scanned for 10
minutes before the channels are available for use. If interference is detected, the access point changes to a verified backup
channel with minimal disruption to the audio performance. Channels with detected interference are unavailable for 30 minutes.
After 30 minutes, the system will resume scanning and verifying the channel for use.

Tips to Improve Wireless System Performance

If you encounter interference or dropouts, try the following suggestions:
1. Check the installation of access point:
◦ Ensure a clear line of sight between access point and the conference units.
◦ Mount the access point near or above the conference units.
◦ Make sure people do not block the line of sight between receiver and transmitter.
2. Check that other wireless systems are not causing interference:
◦ Ensure at least 3 meters (10 feet) between access point and wireless routers, computers, or other active 2.4 GHz or
5 GHz sources.
◦ Turn on typical wireless devices prior to the event so the MXCW system has time to select a clean channel.
◦ Avoid heavy wireless traffic activities on nearby networks such as downloading large files or viewing a movie.
3. Additional tips:
◦ Make sure the access point is using all available channels (reselect any channels that were manually deselected
from the web application).
◦ During sound check, mark trouble spots and position participants away from those areas.
◦ Move access point and microphones away from metal or other dense materials.
Setting the Access Point Country and Region (MXCWAPT-B and MX-
CWAPT-W only)
For the MXCWAPT-B and global MXCWAPT-W model variations, the country and region must be set when the unit is powered
on for the first time, or after a factory reset. Use the web application or the LCD menu to set the operating location for compli­
ance with local regulations and to get the most reliable scans.
See Access Point Model Variations for the full list of countries and regions for each MXCWAPT model variation.
