Comba Telecom Launches Multi-RAT Multi-Band Open Radio Solution

• Industry’s first Open RAN multi-RAT, multi-band RRU for 1800MHz and 2100MHz
• Boost Global Trials with its Energy Efficient Open RAN Radio Units

HONG KONG SAR – Media OutReach – 29 March 2021 – Comba Telecom Systems Holdings Limited (“Comba Telecom” or “the Group”, SEHK stock code: 2342), a leading global solutions and services provider of wireless and information communication systems, announced the launch of the industry’s first Open RAN multi-RAT, multi-band Remote Radio Unit (“RRU”) that supports 1800MHz and 2100MHz, promoting widespread adoption of emerging open standards in the globe.

The RRU is designed to minimize the total cost of ownership (“TCO”) for operators and neutral hosts in macro deployments through fast and easy deployment, energy savings, improved coverage and throughput, smaller footprint and easy maintenance. Engineered for efficient high power (320W) operation, the multi-RAT multi-band 4T4R RRU minimizes the environmental footprint and reduces the energy spend for the operator.

As a first in the Open RAN industry the GSM/UMTS/LTE/5G NR multi-mode operation makes it ideal for simple upgrades of legacy sites without compromises. The 4T4R radio supports two LTE/5G NR carriers per band and Dynamic Spectrum Sharing (“DSS”). This enables operators to serve arising 5G traffic demand without additional spectrum or removing LTE service.

Comba has a long-standing collaboration with major industry partners and alliances and has participated in the initial Open RAN trials and lab projects in different regions. With all in-house expertise in interoperability and optimizing radio designs for market specific criteria, Comba enables mobile operators to accelerate time to market, and mitigate the overall technology risk when adopting to Open RAN strategy in their next generation of RAN.

Ms. Annabel Huo, Executive Director, Senior Vice President of the Group and President of Comba Telecom International said, “Comba’s open radio solutions are taking shape by adding future-proof technical features to answer the calls from the markets. The launch of the multi-RAT multi-band RRU is expected to boost an increasing adoption of Open RAN at global scale, and to build more proven cases in different scenarios. Seeing a massive growth of the Open RAN market over the coming years, the open technologies will become mature enough for widespread deployment.”

Comba’s Open RAN solution series will be extending band options with both high power and lower power radios for multi-service scenarios and heterogeneous networks. For the update about Comba’s Open RAN Solution, please visit https://www.comba-telecom.com/en/openran-solutions.
