2.4 GHz Spectrum Overview
GLX-D operates within the 2.4GHz ISM band which is utilized by Wi-Fi,
Bluetooth, and other wireless devices. The benefit of 2.4GHz is that it’s a
global band that can be used anywhere in the world, license free.
Overcoming the Challenges of 2.4 GHz
The challenge of 2.4 GHz is that Wi-Fi traffic can be unpredictable. GLX-D
meets these challenges in the following ways:
Prioritizes and transmits on the best three frequencies per channel
(choosing from a pool of six frequencies across the 2.4 GHz band)
GLXD4R Half-Rack Wireless Receiver
Seamlessly moves away from interference to backup frequencies without
audio interruption
Optional GLX-D Frequency Manager improves RF reliability for systems
with more than two receivers
Continuously scans during usage to rank all frequencies (both current
and backup frequencies)
Antenna mounting accessories and directional antennas (available separately) help reduce transmitter-to-antenna distance and connect to antenna splitter
Shure Incorporated
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 transmitter-to-receiver distance by placing receivers on
the stage with a clear line of sight. You can also mount antennas remotely
using Shure directional antennas to reduce transmitter-to-antenna distance.
Challenging environments include:
Coexisting with Wi-Fi
If you plan to use Wi-Fi during a performance, turn on Wi-Fi devices prior to
turning on GLX-D and scanning for the best channel. GLX-D detects and
avoids other Wi-Fi traffic by scanning the entire 2.4 GHz environment and
selecting the three best frequencies to transmit on. This method avoids WiFi signals and results in reliable performance for your GLX-D wireless system.
“Bursting” Wi-Fi is harder to detect as it is periodic; however, because GLXD only repeats the most important information, even bursts at very high levels
don’t have an effect on your audio performance.
Areas with few reflective surfaces such as:
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
manufacturers, 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:
1. 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.
2. 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.
GLXD4R Half-Rack Wireless Receiver
Shure Incorporated
Additional Tips
Do not place competitive 2.4 GHz receivers near GLXD4R receivers.
Connect more than two GLXD4R receivers to a GLX-D Frequency Manager to improve RF reliability.
Scan for the best available channel by pressing the channel button.
Keep transmitters more than 2 meters (6 feet) apart. This is less critical with shorter receiver-to-transmitter distances or if receivers are connected to a GLXD Frequency Manager.
Note: If transmitters are within 6 inches of non-GLX-D transmitters or microphone cartridges, audible noise is possible.
Move transmitter and receiver away from metal or other dense materials.
During sound check, mark trouble spots and ask performers to avoid those areas.
If there is a strong source of Wi-Fi and you specifically want to use frequencies within that Wi-Fi channel, use the following Group/Channel combinations
(best option listed first):
Wi-Fi 1: Group 3/Channel 8, Group 3/Channel 4
Wi-Fi 6: Group 3/Channel 7, Group 3/Channel 5
Wi-Fi 11: Group 3/Channel 2, Group 3/Channel 1
Remote Antenna Placement
Follow these guidelines when mounting antennas remotely:
Use only low-loss reverse SMA cable to avoid poor RF signal.
Reduce distance between transmitter and antenna.
Mount antennas farther from each other to improve performance.
Position antennas so there is nothing obstructing the line of sight to the
transmitter, including the audience.
Keep antennas away from metal objects and any other antennas.
Consult cable's specifications and calculate signal loss for desired
cable run.
Use one continuous length of cable from the antenna to the receiver to
increase signal reliability.
Always perform a walk-around test to verify coverage before using a
wireless system during a speech or performance. Experiment with antenna placement to find the optimum location. If necessary, mark any trouble
spots and ask presenters or performers to avoid those areas.
Multiple Receiver Systems
To run more than two receivers at the same time, the GLX-D Frequency Manager is recommended to improve RF reliability.
However, you can run multiple receivers without the frequency manager. Select the group by determining the total number of receivers in your system (channel
count). All receivers in the system must be set to the same group.
