Compare RF, audio and control
Keep the wireless link attached to the complete signal pathDigital wireless systems make different tradeoffs across spectrum, diversity, latency, audio format, encryption, networking and control. Compare the deployed path rather than one range or bit-depth claim.
RF
Read architecture and antenna requirements together
Tuning width, diversity implementation, antenna placement, distribution, cable loss and transmitter power shape the working link. No diversity label makes a poor antenna plan reliable.
- Shared spectrum
- 2.4 and 5.8 GHz systems coexist with Wi-Fi and Bluetooth and are not interference free.
- Range
- Treat stated distance as a manufacturer test condition, never a venue promise.
Audio
Add every latency and conversion stage
The wireless link is only one part of monitoring latency. Include console, plug-ins, networking, in-ear monitoring and video synchronization before deciding whether a path fits performers or picture.
- Recording
- A transmitter recording can protect against some link loss but not capsule overload, clothing noise or poor placement.
- Encryption
- Record the exact AES mode, key behavior and capacity; RF encryption is not end-to-end production security.
Control
Design for a lost app or network
Network management can improve scanning, monitoring and coordination while also adding switches, accounts, firmware and failure points.
- Fallback
- Keep a local method to identify, mute and replace a problem channel.
- Firmware
- Test receiver, transmitter, charger, app and network compatibility before updating a working show system.
