The Hop Freq Offset option is not functional in the 900 MHz spread spectrum transceiver. In the 2.4 GHz
Transceivers, Freq Offset allows the user to select a frequency offset, whereby the frequencies used are
offset by 115.2 KHz from other frequency selections in the same portion of the band. For example, if two
networks are operating side by side in the lower 1/3
rd
of the band using 50 frequencies, with one set to
Frequency Offset of 0 and the other to Frequency Offset of 1, the frequencies used in the different
hopping patterns will be offset by 115.2 KHz.
Note:
Regardless of the FreqKey used, all transceivers in either Point-to-Point or Point-to-MultiPoint
networks must be set to identical Hop Tables and Table Size.
