If you’re on a frequency band that’s in the C-Band or 2.5 GHz band, it’s much easier to have wide channels, these really wide channels and you get the full benefit.” 5G Deployment ImpactĪs for how this has impacted current deployments, Fogg noted that Opensignal’s most recent “ 5G Experience Report” showed that T-Mobile US provided the broadest availability, reach, and download speeds compared to Verizon and AT&T. “5G can use up to 100 megahertz per channel. “If you’re below 2 GHz, you’re typically on a 10- or 20-megahertz channel,” Fogg said. These larger spectrum holdings are also important when using 5G technology as it can support much wider spectrum channels – up to 100 megahertz – as opposed to 20-megahertz channels for 4G LTE. and globally is where carriers have got large amounts of new spectrum, typically above 3 GHz, in the 3 GHz to 6 GHz range, or in some cases millimeter wave that they can they can deploy and use for 5G services, that’s where we’ve seen the big uplift in 5G experience over older technologies like 4G,” Fogg said. However, because of that greater propagation, lower-band spectrum is used by more services and thus there is less total of it available to support commercial cellular services. This means that fewer antennas are needed for lower-band spectrum to cover a particular area than for higher bands. Lower-band spectrum, which is now considered spectrum below 2 GHz, has better propagation characteristic than mid-band (2 GHz-6 GHz) and millimeter wave (mmWave) spectrum that is generally above 10 GHz. The amount of spectrum a carrier controls or has access to provides the basis for the amount of information that can be sent using that signal.ĭiving in further, where that spectrum resides has had a bigger impact on how operators have rolled out their 5G services. But what insight can these metrics provide when viewing the strategy operators have used to deploy those networks?Īccording to Ian Fogg, VP of analysis at Opensignal, the deployment strategies and end results are tied directly to what spectrum operators have access to and how they are deploying the infrastructure needed to support those spectrum bands.Īll wireless communication systems are reliant on spectrum to transport a signal. Telecom operators are constantly being judged on their network performance, which is becoming even more important with the deployment of 5G services.
