The company believes this service, combined with its global holdings of 53 terrestrial bands, will take away market share from 5G private networks.
Globalstar announces new XCOM RAN cooperative multipoint radio system. The company says it can handle four times the traffic of a 3GPP 5G network, including indoor venues such as stadiums, campuses, and warehouses. The operator said that “one of the world’s largest global retailers” is introducing new services.
The solution is a tailored multipoint radio system that delivers “significant capacity improvements over traditional in-building solutions” for high-density deployments of 5G infrastructure. Unlike traditional in-building solutions such as small cells and distributed antenna systems (DAS), XCOM provides extremely high downlink and uplink capacity that is ubiquitous and highly concentrated. These performance improvements are achieved within a single logical cell made up of multiple remote radio units (RRUs). This means there is no interference between cells and brief interruptions due to cell handovers are a “thing of the past”.
Globalstar hired independent research firm Signal Research Group to bring this system to a close once and for all. The results have certainly given the company new forays into the private 5G network space. Signal found that the service offers very high downlink and uplink capacity because nearly all resource blocks on each MIMO layer are highly reused. Average downlink capacity reached over 4.5Gbps on 100MHz TDD spectrum (64.6bps/Hz), while uplink average throughput of nearly 770Mbps (38.3bps/Hz) with spectrum allocation biased towards the downlink. was recorded.
Also, a high degree of reuse of network resources (up to 16 downlink MIMO layers and up to 12 uplink MIMO layers, with almost complete reuse of all resource blocks (RBs) in each layer) was observed. We also found that the main explanation was the profit that was generated. More MIMO layers are possible in one or both directions, depending on the network configuration and device capabilities.
Not affected by location or device number
Signal said many of its tests incorporated 1 to 96 devices placed next to each other on up to 12 carts distributed over an 8 RRU network (up to 204 devices at a time). Ta. In one test, he pushed all 12 carts together, resulting in 204 devices directly under one of his RRUs.
“There was only a small difference in total network capacity between these configurations. Obtaining high bidirectional spectral efficiency with distributed devices is another thing. Achieving this performance by literally stacking devices on top of each other is one thing. It’s a completely different thing,” Signal concludes.
After testing, Signal said stadiums, arenas, and similar venues with high concentrations of smartphones that generate large amounts of data traffic in both directions are ideal for the service. “However, the benefits are [the service] Private indoor networks targeted at factories, warehouses, and other large building structures may have a limited amount of available spectrum, making it difficult to provide reliable and ubiquitous coverage while meeting demands. It is even more important if you need a robust network to provide. It’s a concentrated capacity that can vary over time and location,” Signal said.
The research firm added that warehouses and micro-fulfillment centers – two areas that can struggle to connect due to aisles, heavy racks and offices – are also suitable for Globalstar’s services.
This year’s service
Globalstar provides connectivity solutions consisting of hardware, software and services, with several systems scheduled for delivery in 2024. The company indicated that the kit will be Open RAN compliant and feature “co-processing algorithms that support superior end-to-end systems.” It allows users to scale quickly and economically while improving performance and eliminating handoff boundaries and interference conditions. ”
With XCOM RAN, we set out to apply our decades of wireless system design experience to creating innovative and differentiated performance for private wireless 5G networks and beyond.” Globalstar CEO Paul Jacobs said (On top of that). “We have significantly increased the amount of data that can be transmitted on a given spectrum allocation while improving other performance metrics. All of this is done within a flexible solution that is poised for future performance improvements. Masu.”
“5G private networks are being used for many applications,” added Tamer Kadous, Vice President of Terrestrial Networks at Globalstar. “XCOM RAN benefits any use case, but stands out when addressing the most demanding KPIs. Our first product launch marks the culmination of our intensive efforts over the past several years. We are delighted with this achievement and proud that our first commercial sale is with one of the world’s largest retailers.”
