Expeto, a software company in the private wireless space, is providing Portland General Electric (PGE) with a private wireless network that spans an area over 4,000 square miles and 250,000 connected grid elements.
How is that even possible, you might ask? Donāt private wireless networks need some kind of clearly-defined boundary such as an industrial campus, a school building or even the boundaries of a city?
Apparently not.
Expetoās software treats a companyās private wireless network almost like software-defined wide area networking (SD-WAN) technology, which transformed the enterprise networking landscape.
The software can use public wireless networks or tap other spectrum. For instance, in the U.S. Expetoās software could use a mix of public wireless along with CBRS spectrum, whether itās through a priority access license or general authorized access.
Michael Anderson, CEO of Expeto, said the companyās software allows enterprises to integrate wireless into their IT systems. āThat is unique,ā he said.
For PGE’s private network, it will be using existing public cellular networks.
Anderson is not revealing which carrier, or carriers, PGE is leveraged for its private wireless network. But he said, āIn terms of carriers, we have relationships with public carriers all over the world, and where we donāt, we can use traditional roaming. Our whole business model is on software.ā
Expeto can put multiple profiles of public carriers on PGEās SIM cards. And then the companyās software uses 3GPP interfaces allowing PGE to use the public signals, including LTE and 5G, from various carriers.
Asked if this technology was similar to network slicing, Anderson said 5G network slicing will be used to āvirtualize channels on the RAN,ā but that technology has more to do with the carriers and how they sell their services.
Expeto is focused on private wireless from the enterprise perspective. Its platform provides the wireless core, the SIM and the orchestration-level patented IP that enables enterprises to deploy and manage private networks in a way that suits their business needs.
The company does not make any hardware. It sources its radios from other vendors such as Ericsson, Nokia and Airspan.
Expeto worked with PGE for a year testing various use cases such as wildfire cameras, electric vehicle (EV) charging, smart meters and distributed energy management gateways.
PGE ā whose territory covers half the state of Oregon, some in rural areas and some in urban locales ā plans to use the private wireless network to support automated grid resiliency, monitoring of field conditions with smart sensors and devices, connected workers for employee safety and charging stations for EVs.
Expeto says by using connectivity from Tier-one mobile operators, companies such as PGE receive the functionality of a private wireless network without the capital and operating expenditures of a typical 10-year private network buildout that would require spectrum acquisition, RF analysis, hiring and training teams of engineers and subcontractors, and tower and radio infrastructure permitting and deployment.
Expeto
Expeto is a private company headquartered in Canada with about 50 employees. Itās been working with the Canadian operator Rogers Communications, which uses Expeto as its private wireless partner.
Anderson said, āWith Rogers our platform is fully integrated in their Rogers for Business. Every private wireless network they sell is with Expeto.ā
Expeto focuses on medium to large enterprises, many in āmission criticalā businesses such as PGE.
According to CrunchBase, Expeto has raised $25.9 million.
