Dual License - Design Type Setup
For all the modulations schemes and bandwidths, Proxim provides one unified firmware (from
version 0207 and higher).
The firmware support two design types:
• Design type 301, which permits to switch between bandwidths in the range 7 – 30MHz
• Design type 303, which permits to switch between bandwidths in the range 28 – 56MHz
The firmware adapts automatically to uploaded license file in the device.
To configure these parameters, navigate to main menu “Maintenance” and sub-menu
“Miscellaneous”.
After configuring the parameters, click Apply.
Click “COMMIT” to save the configured parameters.
!! Note !! IDU with license for 301 design only (Bandwidth 7 – 30MHz) can work with IDU
with license for 303 design and also these IDUs should run on the specific modulations.
The modulations with “b” index in 303 design can work with the same modulations in 301
design. Example, qam128_28e6_02b 163,24Mbps
Frequency, Modulation and ATPC Setup
The set modulation scheme and the channel bandwidth affects the final data rate (data
throughput) and sensitivity (bridging distance) of GX800 link. Generally, the narrow the band and
lower modulation, the greater the sensitivity.
There are also used self-correcting codes in the modulations. It is the rule that in the same type
