Frequency Channel Plan D
Frequency plan D allows independent control of transmit and receive frequencies.
This enables a very flexible frequency plan and can be used to overcome interference
in the 5.8 GHz ISM band.
The frequencies that can be used in the lower or upper sub-bands can be selected in
1 MHz increments. Performance degradation can be expected when operating using
channel plan D mode and the chosen frequencies are close to the sub-band edges i.e.
a choice of one of the high frequencies in the lower sub-band and one of the lower
frequencies in the upper sub-band.
The allocation of Channel plan D frequencies is shown in Table 2.

2.2.2 RF Power Output Options
The Outdoor Unit is designed for use in countries that have adopted FCC standards.
It is possible to adjust the output power on the OU using the supplied NMS software or
a SNMP Management application.
2.2.3 MDR5800 Outdoor Unit
The MDR5800 Outdoor Unit transmits and receives RF through a diplexer interfaced
via an RF cable to an external antenna. The unit has a type-N connector for
connection to the RF cable used between the OU and the antenna.
The MDR5800 Outdoor Unit houses the following main parts:
• Transmit/Receive Modules
• Baseband Modulator/Demodulator Circuitry
• Microcontroller/Framing & Buffering Circuitry
• Power Amplifier
• Diplexer
