Companies around the world are recognizing the benefits of acquiring mobile spectrum packages from their home country’s mobile carriers to operate private networks, and in the United States, after years of regulatory, standardization, and technology implementation activity, broadband wireless service (CBRS) has been put into practical use. The 3.5 GHz spectrum band helps support new applications at an affordable cost.
However, ABI Research finds that despite the continued deployment and commercial success of CBRS shared spectrum platforms, significant improvements will need to be made for large-scale deployments to deliver on the promise of enterprise 5G. concludes.
paper, Dynamic spectrum sharing for private mobile phonesThe report, commissioned by radio frequency (RF) infrastructure, monitoring and analytics company DGS, notes that private cellular is a relatively new value proposition in the enterprise space and that enterprises are deploying mission-critical wireless networks on-premises. It states that existing and new services can be realized. Type of use case. The company notes that many companies are now deploying these networks to improve existing use cases and enable new ones.
Existing use cases include overcoming Wi-Fi security and coverage limitations. For example, manufacturing plants deploying private cellular networks to improve connectivity for automated guided vehicles (AGVs) can significantly increase AGV speeds and operational efficiency. In new use cases, companies such as mining companies are deploying private mobile phones in open-pit mines, enabling fully automated operation of equipment such as trucks and drilling rigs. This is said to have greatly improved human safety, especially in areas where blasting takes place.
However, ABI says there are several significant challenges to overcome before success is guaranteed, including overestimation of interference levels, rising costs and staggering 24-hour latency to detect spectrum interference. I warned you.
ABI proposes Dynamic Spectrum Sharing (DSS) as a solution to these problems, enabling near real-time decision making with much higher accuracy. At the same time, he noted, policymakers are about to announce changes to U.S. spectrum auction policy that would require some form of spectrum sharing, as recommended by the National Telecommunications Information Administration (NTIA).
While interference management and RF awareness are considered to be key areas for improvement in this paper, the problem is to understand the RF channel in near real time and identify potential sources of interference effectively, also in near real time. It warns that it can only be addressed by ensuring that it is managed. This is not possible given the state of the CBRS framework, and the improvements proposed by the OnGo Alliance, an industry consortium that accelerates the development, commercialization, and adoption of LTE and 5G solutions, need to be widely adopted and implemented. The company said there is. Ensures that your deployments behave the same everywhere.
The dynamic spectrum sharing proposal put forward by DGS aims to enable interference and channel impairments to be addressed in near real-time. The company said this is necessary to ensure that the General Authorized Access (GAA) network remains interference-free and is not dependent on the CBRS framework or the rigorous planning processes used by SAS providers.
Ultimately, the paper says, better RF interference, visibility, and management solutions are needed for the CBRS spectrum to fulfill its promise and deliver reliable, carrier-grade wireless networks to more businesses. That is to say.
In conclusion, this study shows that mission-critical mobile phone systems need to be robust, resistant to interference, and require tens of hours to reconfigure power levels if a nearby source of interference appears. They point out that you don’t have to wait. ABI Research anticipates that dynamic spectrum sharing will not only be necessary for future GAA implementations, but will significantly enhance their capabilities.
Research shows that, beyond CBRS, enabling true dynamic spectrum sharing will help the telecommunications industry use mobile network spectrum more efficiently, thus facilitating an increasingly digital society. He says it will be an important tool. Dynamic spectrum sharing was expected to become an even more important component of comprehensive digitalization strategies, especially with the increasing importance of topics such as sustainability and efficient use of resources.
