Where:
MCS: Modulation and Coding Scheme
Spatial Streams: all Mesh2HT radios are 2x2
Modulation Types:
BPSK= Binary Phase-Shift Keying
QPSK= Quadrature Phase-Shift Keying
QAM= Quadrature Amplitude Modulation
Coding Rate: Useful proportion of the data-stream
Channel Frequency:
Automatic: This facility is only on the host/AP. To do this select the Basic Wireless
option and ensure that the ‘Auto’ box next to the Channel-Frequency is ticked. The
frequencies available to be automatically selected will be based on both the Country
Code and Spectrum Width chosen.
Manual setting: the frequency can also be selected manually, this is necessary if there
are more than one Mesh2HT links on a site. It is recommended that an Interference
Analyzer survey is conducted to determine which frequencies are the least congested to
use. See the Interference Analyzer section below for details.
Setting the Host / AP frequency:
On the host/AP radio in the Basic Wireless: Radio 2 (default is Radio 2) option use the
drop down menu to choose a unique frequency for the link you are setting up.
Frequencies available will depend on the Country Code & Spectrum Width selected. Once
a frequency has been chosen, select
Note:
on the EMEA firmware versions you can choose whether to include the 5600 –
5650MHz band. If these frequencies are included, the link connection time can increase
to 10 minutes due to Dynamic Frequency Selection (DFS) regulations see page 8.
