5G is transforming the landscape of the communication networks. With the combination of ultra-high-speed and extremely low latency, it will enable several path-breaking use cases like Industry 4.0, connected vehicles, Augmented Reality (AR), Virtual Reality (VR) and Artificial Reality (AI), apart from several others. With 5G, the service providers are able to connect billions of people and devices without any impact on the quality. 5G will connect 1.2 billion people across the globe by 2025, according to GSMA. To deliver on the promise of 5G, the service providers will need to adopt the strategy of network densification to increase the amount of capacity available and to offload traffic from nearby sites. This is especially true for urban areas or areas which have a high concentration of mobile users. A greater number of macro-cells, along with small cells, will need to be installed to ensure high-speed and low-latency network performance.
STL Firebird is a portfolio of multi-band macro O-RUs available in different bands (currently band 1 and band 41). These carrier grade macro O-RUs are compliant with 3GPP Release 15 and can be upgraded to Release 16 through software updates. Read More..
These standardized O-RUs works seamlessly with O-DU from any vendor to form the gNodeB and supports the delivery of high-speed data, mobility, seamless voice and broadcast services. STL has formed strategic partnerships with several vendors to provide an integrated solution, which will enable service providers to address several deployment use cases with a faster time to market. These O-RUs supports multiple component carriers in several configurations covering LTE, NR & NB-IoT technologies with an antenna configuration of four transmit and receive paths (4T4R). The units are physically compact, easy to install and have high conducted output power, making them a good fit for outdoor deployment. With a carefully crafted design, this product succeeds in minimizing physical footprint, power consumption and the overall OPEX of service providers. STL's Firebird leverages the company's rich experience in the industry and takes forward our legacy of bringing cutting-edge technology products. Read Less..
Faster Time to Market
These standardized O-RUs are interoperable with O-DUs from several vendors, hence faster time to market
Standardized open interfaces enables innovation and competition among vendors and hence better cost
With low power consumption, it helps bring down the operational expense for the service providers
Easier Deployment in Outdoor Settings
These O-RUs are carrier grade hardware (IP 65 rating) and robust enough to face the harsh and challenging conditions of the outdoor environment
Easy field set-up and verification, software diagnostics and easy "hitless" upgrades
Several new terms, including Centralized Unit (CU), Distributed Unit (DU) and Radio Unit (RU), were introduced in the 3GPP 5G RAN architecture in release 15. However, the most demanding interface in 5G RAN transport is between the RU and DU.
In simple terms, RU is the radio hardware unit that converts signals from the antenna into a digital signal for transmission over packet networks. Essentially, it manages the front end, the lower PHY layer as well as digital beamforming functionality. The key factors in 5G RU designs are size, weight and power consumption.
The Open RU or O-RU includes both traditional macro radios and Massive Multiple Input Multiple Output (MIMO). It addresses key challenges of bringing down cost and quickening the time-to-market without impacting the network performance.
O-RAN Alliance defines O-RU as a "logical node hosting Low-PHY layer and RF processing based on a lower layer functional split. This is similar to 3GPP's "TRP" or "RRH" but more specific in including the Low-PHY layer (FFT/iFFT, PRACH extraction)."
Typically, the outdoor environment demands that O-RUs perform in harsh and sometimes remote and difficult to reach settings. Therefore, the O-RU should be resilient and robust to face extreme variation in day and night temperature coupled with rugged terrain. In addition, O-RU should be geared to support still evolving 5G standards and should come with the ability to perform remote software upgrades.
