Core Radio Specifications: Uplink and Downlink Performance
n
At the heart of this radio unit is its ability to operate across key frequency bands with exceptional bandwidth and power output. The advanced radio specifications ensure seamless support for both LTE and NR (5G New Radio) technologies, making it a versatile choice for network upgrades and expansions. The unit covers Band 1/N1, offering uplink frequencies from 1920 to 1980 MHz and downlink frequencies from 2110 to 2170 MHz, providing a solid foundation for wide-area coverage. With an instantaneous bandwidth of 60 MHz and an operation bandwidth of 40 MHz for both uplink and downlink, the radio handles high data throughput efficiently.

Fronthaul Connectivity and Data Rate Capabilities
n
To fully leverage the advanced radio specifications, the unit incorporates an O-RAN Split Option 7-2x interface, which optimizes the balance between centralized and distributed processing. This split reduces fronthaul bandwidth requirements while maintaining low latency. The unit is equipped with two SFP ports for fronthaul connections, supporting a maximum data rate of 10.137 Gbps. This ensures that the radio can handle the high-speed data streams generated by 5G services, including enhanced mobile broadband and ultra-reliable low-latency communications. Compliance with 3GPP standards (TS36.104, TS36.141, TS38.104, TS38.141) guarantees interoperability and performance consistency across multi-vendor networks.

Environmental and Physical Resilience
n
Deployed in challenging outdoor environments, this radio unit is built to withstand extreme conditions. Its operating temperature ranges from –40°C to +55°C without solar radiation and –40°C to +50°C with solar radiation, making it suitable for harsh climates from arctic cold to desert heat. The unit maintains functionality within a relative humidity range of 5% to 100% RH and an absolute humidity of 1 g/m³ to 30 g/m³, ensuring reliable operation in high-moisture areas. Atmospheric pressure tolerance from 70 kPa to 106 kPa allows deployment at various altitudes, while shockproof protection meets NEBS GR63 zone4 requirements for seismic and vibration resistance. With an IP65 ingress protection rating, the radio is completely protected against dust and low-pressure water jets, ideal for outdoor pole or tower mounting.
