Wireless camera and lens control devices have many advantages. However, interference from other radio and microwave signals can cause problems. In these two white papers from Preston Cinema Systems, methods for detecting and avoiding this interference are discussed.
The Wireless Jungle – This brief tutorial is intended to provide insight into the causes of interference in the 2.4 GHz band and describe steps that can be taken to avoid communication disruption. A basic overview of the technology used to send data over wireless channels is outlined. Methods to choose clear channels are also discussed.
How to Avoid the Wireless Interference – The best way to avoid interference is to determine which other devices are using the 2.4 GHz band, and choose a clear channel for the FI+Z. A spectrum analyzer provides a graphical display of radio signals, showing the strength of the signals versus their frequency or channel. Inexpensive analyzers and software have recently become available which allow any camera assistant to survey a site for 2.4 GHz activity. The operation of these devices is outlined in this white paper.
