The High Capacity Radio Relay—IRR-B4(HCRR) is indigenously designed and developed by ICS . It operates in Band –IV (4400 MHz to 5000 MHz) capable of Full-Duplex Data transfer up to 100 Mbps.

High Capacity Radio Relay—IRR-B4(HCRR) can be deployed for

1. Point to Point (P2P) Communication link:

Data rates supported : up to 100 Mbps for a range of 20 km and up to 40 Mbps for a range of 40 km in Fixed Frequency mode
Data rates supported : up to 8 Mbps for a range of 20 km in Frequency Hopping mod

2. Point to Multi Point (P2MP) Communication link

Data rates supported : for a range of 20 km with 8 Mbps aggregated data rate for outstations

3. Repeater mode

The system can also be configured to serve as a single hop repeater with 100 Mbps data rate for establishing Communication up to 40 km and with 34 mbps data rates for establishing communication up to 75 km

The system has inbuilt ECCM features such as Frequency hopping, Frequency evasion, Adaptive Frequency Control and Adaptive Power Control
The above features of IRR-B4 are also characterized by optimized transmit power and RF channel band width
System has E1, E3 and Ethernet base band interfaces, with both Electrical and Optical connectivity. System accepts 230 V AC and +48 V DC with auto changeover facility
System has Narrow beam antenna for P2P Communication and Sector Beam Antenna for P2MP Communication
