ما توصّل إليه النقاش

• The BFD wireless follow focus system operates in the 900-927 MHz license-free band in the US
• A 900 MHz video transmitter placed near a BFD receiver can cause the receiver to overload, resulting in loss of reception
• Careful positioning and channel selection may allow a 900 MHz video system and BFD to coexist, but this approach is unreliable
• A 2.4 GHz or 2.5 GHz video transmission system is recommended when using a BFD to avoid frequency interference

يعتمد على

• The interference issue and recommended frequencies apply to US license-free band regulations
• Success with simultaneous 900 MHz operation depends on specific equipment placement and channel choices, making it unpredictable
