Regions will only show the available channels for that location.
See below for a diagram of the frequency ranges and channels.
Each Country/Region has a different frequency regulation with multiple band widths and numerous channels available.
The main reason for having different channels and bandwidths is to allow multiple radios to operate in close proximity
with minimal interference.
As you can see from the Channels Diagram and the Data Throughput Table (below) the greater the band width the
greater the overall data throughput.
If selecting the high band width, i.e. 20MHz you will be limited to one channel which may be more susceptible to
outside interference because it spans the available 900MHz frequency range, in some regions this high band width
option may not even be available.
If selecting the lower bands, i.e. 1.25MHz you have more channels available and each channel is non-overlapping
(Adjacent channels do not cross over), however the Data throughput will be considerably lower.
If you require a high data throughput then the higher band width will need to be selected and care with antenna
placement, etc will also need to be taken into account.
Selecting a 20 MHz channel will give the maximum TCP/IP throughput of around 22 Mbps however if the
band width is reduced (10MHz, 5MHz, etc) the maximum data throughput will also be reduced
For an indication of the data throughput levels used with different channel bandwidths see
“XYR301-E Radio Data Throughput” table below.
Radio Throughput
Below is a table showing the maximum TCP/IP throughput based on channel selection and receiver signal level. There
are five channel bandwidths (20, 10, 5, 2.5, & 1.25MHz). These throughput estimations are based on perfect radio
conditions, i.e. little to no outside radio interference present while data is being passed and they are calculated using
real life conditions and communication constraints. Higher data rates are achievable by using an external Iperf
arrangement. For more details on this see section 4.5
