WiCOM-Fuel provides a long range wireless method of fuel or liquid level measurement. LPG, diesel, lubricating oil, aviation fuel or even water. High levels of accuracy and long range
Typically once every five minutes
The short answer is no! The longer answer is that it is designed to co-exist. Both WiFi and the CSMA-CA scheme used on 802.15.4 look for clear spaces to transmit into and therefore avoid 'collisions'.
No, the channels are different from WiFi and can't be snooped on by domestic equipment. In addition the very short bursts would be hard to capture and finally 128bit encryption may be employed.
The performance of the 802.15.4 transmission is between 7 and 18 dB better than that of 802.11b. This can be directly translated to a range increase from 2 to 8 times the distance for the same energy per bit, or an exponential increase in reliability at any given range. We also use the highest permissable levels of power.
