Chapter 12 ‒ ShowLink™ Network
ShowLink Basics
Within the 2.4 GHz spectrum, 16 channels are available for ShowLink communication. To ensure reliable communication,
the access point contains an internal scanning radio that analyzes the 2.4 GHz spectrum hundreds of times per second.
If interference is detected, the access point uses channel agility to automatically switch to a clear channel within the spec-
trum. All transmitters associated with the access point will continue to communicate uninterrupted on the new ShowLink
channel. If ShowLink goes off-line for any reason, audio transmission will not be interrupted.
ShowLink remote control enables real-time remote adjustments of all transmitter parameters using a wireless network
connection between linked Axient transmitters and receivers. Whether performers are on stage in the middle of a perfor-
mance, or off stage waiting for their cue, ShowLink lets you make crucial changes to transmitter settings without inter-
rupting the performers. Simply add an AXT610 ShowLink access point to any Axient network and instantaneous wireless
transmitter control is realized over a wide coverage area for up to 16 transmitters. Additional access points can be added
to extend the coverage area and to increase the number of supported transmitters.
ShowLink Channels and 2.4 GHz Spectrum
ShowLink channels that enable remote control of Axient transmitters operate in the 2.40 to 2.484 GHz portion of the RF
spectrum in accordance with the IEEE 802.15.4 protocol. Devices that share the 2.4 GHZ spectrum, including Wi-Fi, are
manufactured to efficiently share the spectrum and cause minimal interference. Both ShowLink and Wi-Fi use "listen be-
fore talk" technology to transmit short message packets only when needed to conserve bandwidth. Available spectrum,
low interference, and global availability make the 2.4 GHz spectrum an ideal choice for hosting ShowLink channels.
