Challenging Wireless Environments
Some environments are more difficult than others for 2.4 GHz wireless system performance. Additionally, body absorption has
a greater impact in the 2.4 GHz spectrum compared to the UHF spectrum. The simplest solution in many cases is to reduce
transmitter­to­receiver distance by placing receivers on the stage with a clear line of sight. You can also mount antennas re­
motely using Shure directional antennas to reduce transmitter-to-antenna distance.
Challenging environments include:
Areas with few reflective surfaces such as:
Outdoors
Buildings with very high ceilings
Three or more GLXD4R receivers in use and not connected to a GLX-D Frequency Manager
Areas with a strong Wi-Fi presence
2.4 GHz systems from other manufacturers in use
Note: Unlike analog TV band wireless system which typically use the same type of transmissions across manufacturers, all 2.4 GHz wireless currently on the
market use different variations of wireless transmission. These differences make it more difficult to mix and match 2.4 GHz systems from multiple manufactur­
ers, as can be done with TV band wireless solutions.
Tips to Improve Wireless System Performance
If you encounter interference or dropouts, try the following suggestions:
Place receiver at least 3 meters (10 feet) away from Wi-Fi access points, computers, or other active 2.4 GHz sources.
Avoid heavy Wi-Fi traffic activities such as downloading large files or viewing a movie.
Turn on any Wi-Fi prior to turning on GLX-D and scanning for the best channel.
Reduce transmitter-to-receiver distance by placing receivers on stage or above the audience with a clear line of sight to
the transmitter.
Move receiver to the top of the equipment rack for a clear line of sight.
Mount antennas remotely to place closer to transmitters and improve RF reliability if receivers cannot be moved
closer.
Make sure people do not block the line of sight between receiver and transmitter.
