The propagation characteristics of Wi-Fi are simply inadequate to support emerging enterprise use cases. While 2.4GHz Wi-Fi offers large coverage at lower data rates, 5GHz Wi-Fi delivers high data rates but a smaller coverage area. On top of coverage and capacity limitations, enterprises face security vulnerabilities – reasons that lend acceleration to PCNs. The advent of Industry 4.0, together with 5G innovations that bring capabilities such as low latency, edge compute and high bandwidth, drives further interest in 5G private networks to support connectivity at scale.
In the words of George Mulhern, CEO of Cradlepoint, “Anything that can be wireless, will be wireless.” PCNs are transforming LAN, similar to the early days of SDN and SD-WAN. We believe that PCNs hold the future of connectivity.
Increasingly, enterprises and governments demand a greater degree of control in an end-to-end environment to achieve enhanced security and performance capabilities. Since Wi-Fi and public networks cannot provide the desired reliability and security in enterprise settings, private cellular becomes a requirement. Widespread adoption of MEC and edge computing fuel the need to be closer to the edge, making PCNs a value proposition. Currently, we are witnessing a rise in use cases across mines, large distribution centers, manufacturing facilities and transportation hubs, where security and interference-free connectivity are critical.
As we know, one of the lifeblood of PCNs is spectrum. Some world governments have started to make dedicated spectrum available for private networks to enable IoT and other applications. For instance, Germany has opened doors to private networks by offering corporate licenses to spectrum. In the US, the Citizens Broadband Radio Service (CBRS) allows unlicensed, lightly-licensed and licensed spectrum to be shared. However, outside of the US, we find ourselves working with operators that possess licensed spectrum to deploy PCNs. Even though operators have been developing the ecosystem to provide private cellular, it is not the same when enterprises can deploy their networks.
What are the challenges for deploying PCNs and how is Cradlepoint making breakthroughs in this area?
Our first private cellular network was deployed about six years ago in the north of the Arctic circle in Canada, to conduct mining in a remote area. To provide wide-area connectivity, one of our partners built a dedicated, on-site infrastructure that provided Wi-Fi and ethernet using our endpoints. This was how we became a hub for wide-area connectivity and got started on PCNs.
