Hi, I have some questions about range.
Now, I’m doing test of a range of XBee depending on both type of antenna and type of module, using Xctu and range test(rssi).
Result is below: ( signal strength )
(XBee S2C + wire antenna) > ( XBee 3 pro U.FL + 5 dBi antenna ) (about -15 dBm differnece)
(XBee 3 pro U.FL + 5 dBi antenna) has a similar power with (XBee 3 pro RPSMA + 5 dBi antenna) and (XBee S2C U.Fl + 5 dBi antenna)
Above results tell me that a type of antenna is more important that module type with respect to a range.
Why the module having the strong signal is XBee S2C, not XBee 3 pro? that’s just because of antenna?
- 15 dBm difference will be an important thing in a messy Environment ( large metal structure, about 15m distance, another Zigbee PANs nearby - 20m distancce )?
My XBee S2C(wire antenna) shows -20 ~ -40 dBm rssi in a distance of 10m(in my office). Is it reasonable and acceptable value?
What is boost mode? It’s just full-power mode and out of control when operating?
please, let me know. Thank you.
