Split Mount Radio (IDU+ODU)
A Split Mount Microwave Radio consisted of Indoor plus Outdoor components – specifically Indoor Unit (IDU) and Outdoor Unit (ODU)
Split Mount Microwave Radios offer up to 500 Mbps and 1Gbps Full Duplex payload and higher up to 6Gbps or more, in 4-42GHz licensed frequency bands.
Indoor Unit (IDU)
A Typical Split Mount Radio consists of a 19″ Rack Mount Indoor Unit which is mounted in a rack, cabinet, comms room, or even roof-mount shelter as possible locations.
Outdoor Unit (ODU)
The Outdoor Unit (ODU) is typically mounted directly to the Microwave Antenna on a rooftop or tower location, which enables clear Line of Sight (LOS) between both ends of the Microwave link.
For most bands above 6GHz the ODU has a waveguide interface which enables efficient, low-loss connection directly to the antenna. For lower bands below 6GHz, commonly a coaxial cable is used between the ODU and the antenna.
In certain cases, the ODU can be remote mounted from the antenna, and a waveguide used to connect between them
Comparison with Full Outdoor Radios
A split mount radio is considered a “traditional” design and older radios always feature this. The Indoor Unit has all the network interfaces and processing in the easy-access indoor location at the foot the tower or building. Full Outdoor Radios by contrast have all the active items including the modem and user network interfaces inside the rooftop radio element. This saves on space, materials, installation time and cost. A downside is that in the event of any failure, a tower climb is almost always needed to rectify any fault, which may be impossible in rough weather, or require permits or have access limitations to reach
Distances and Range Capability of Split Mount Radios
Using suitable antennas and sites, ultra-long-distance links exceeding 100km can be achieved. Distances depend on:
- Frequency band
- Regional Rainfall
- Required throughput (Mbps)
- Desired Availability (%)
- Antenna size (gain)
