Hi all, I wanted to find more about the 'Pros and Cons' of using 2.4 GHz Frequency hopping spread spectrum radio modems. One of the established Telemetry equipment vendors (in Australia) suggested that spread spectrum modems are suitable only for short range applications (e.g., Tank farm) and are ill-suited for a robust Telemetry network spanning up to 10 Kms (radius). In fact the current network we would like to install can be better described as 'Remote IO networks connected by radio modems' rather than the 'TRUE' telemetry network.
I also know that the 2.4 GHz spread spectrum radio modems are relatively a new product (< 2 years on the market) as compared to the licensed 400 MHz (2400 BPS) radios.
I would like to hear from people who have designed, installed and commissioned wireless / telemetry networks about the pitfalls to avoid when using the 2.4 GHz modems. Thanks for sharing your experience in advance. Regards, Raj Sreenevasan
