In order to obtain speed range calculation for the link (for 5GHz devices only),
please refer to “Speed range calculator”.
Landscape details and signal propagation path obstructions are not
taken into account in the calculator.
Speed range calculator
Speed range calculator is used for Speed/Coverage parameters calculation for
the link. The Calculator is available at the www.infinetwireless.com web-site
in the Support section.
The Calculator works for 5GHz devices only
The procedure for the Calculator usage is the following:
1. Specify “Distance” and “Frequency” parameters of the link
2. Specify “Antenna Gain” for “Base Station” and “CPE”
3. Specify “Cable Attenuation” per 1 meter cable length
4. Specify “Output power” in milliwatts
5. If you use external amplifiers, fill out “Amplifier” section(s)
6. Press “Calculate” button
The results are presented at the right side of the table. “Best” and “worst” values
for bitrates both for BS and CPE act as recommendations only when planning
the network. The worst value implies lower energetic parameters for the clients
that are located on the sides of the BS sector antenna radiation diagram or on
the limit of the fade margin.
Landscape details and signal propagation path obstructions are not
taken into account in the calculator. Please refer to the “Remarks”
section.
2. Link diagnostic tools
Muffer
The muffer module makes it possible to rapidly test the electromagnetic
environment, visually estimate the efficiency of the utilization of the air links,
reveal sources of interference, and estimate their power.
Several operating regimes of the muffer module provide for different levels of
details in test results
Review mode
This regime is enabled by the review option. It makes possible to have a general
estimation of emissions and interference within specified frequency range.
Normal operation of the radio is not possible in this mode.
This regime can be useful on the first steps of link configuration. One can
observe the activity on the selected list of frequencies and make decisions of
