O2 Telefonica said it is working with module and device manufacturers to drive development of RedCap technology
German telco O2 Telefónica, which is controlled by Spanish operator Telefonica, said it is currently trialing 5G Reduced Capability (RedCap) technology.
In a release, the operator noted that it has successfully trialed the integration of 5G RedCap devices in its commercial 5G network in Munich.
“With our network, we are creating the technical prerequisites for connecting millions of devices efficiently and cost-effectively. It will be crucial to see how the market, the product world and digital applications develop,” said Mallik Rao, chief technology and information officer of O2 Telefónica.
RedCap, sometimes referred to as NR Light, is a reduced set of 5G capabilities intended for devices like wearables and low-cost hotspots that have low battery consumption, lower costs and lower bandwidth requirements. Introduced with 3GPP Release 17, 5G RedCap is designed for devices currently served by LTE CAT-4 but provides equivalent or better in performance with up to 150 Mbps theoretical maximum downlink throughput. This technology helps reduce the complexity, cost and size of 5G devices.
The German telco noted that its 5G network is prepared for the use of 5G RedCap, as it does not need dedicated antennas. O2 Telefónica also said it is working with module and device manufacturers to drive development of this technology.
O2 Telefonica recently said it has already deployed nearly 10,000 5G base stations since it initially launched 5G services in October 2020.
The German operator said it deployed an average of more than 50 new 5G transmitters every week since the launch of the network. Last year alone, the carrier installed 3,000 5G base stations across the country. The telco said its 5G network currently reaches 95% of Germany’s population.
In October 2023, O2 Telefonica announced the launch of its 5G Standalone (SA) network in the country under the 5G Plus brand. Until this launch, the German telco had been offering 5G services through the NonStandalone (NSA) 5G architecture partly via its LTE/4G core network.
The carrier noted that the new network will enable customers to have access to voice-over-new-radio (VoNR) technology, which enables them to make calls with even better voice quality over the 5G network.
O2 Telefónica said it has already been using the 5G SA technology in 5G campus networks for companies and public authorities since 2020. With this new launch, the company noted that more companies in different sectors such as industry, healthcare and the public sector will have access to improved connectivity.
The carrier’s 5G Plus uses frequencies in the 700 MHz, 1.8 GHz and 3.6 GHz bands. The telco said it expects its 5G SA service to reach full coverage in Germany by the end of 2025.
Last year, O2 Telefónica and Ericsson had completed a proof of concept (PoC) with the aim of paving the way for the development of 5G cloud RAN technology in Europe.
Ericsson and O2 Telefonica noted that this collaboration “validates the feasibility” of cloud RAN for enterprise and industry-specific use cases as well as fixed wireless access (FWA) use cases.
