Back in 2017, the UK launched its 5G Testbeds and Trials Programme, the stated aim of which was to support coordinated research into 5G technology and use cases among British telecom businesses, equipment manufacturers, and scientists. By their account, the creation of these 5G testbeds provides a crucial proving ground for technology that’s still taking shape, and whose full uses haven’t come close to being explored yet. The UK envisions a world in which 5G powers increased connectivity in rural areas, on roads, and along rail lines, as well as smart tourism and smart cities and towns, but they won’t know whether these goals are realistic until they’ve had the chance to test things out in a safe environment.
When technology changes and evolves—as it does almost constantly—in the telecom domain, it typically takes standard-setting bodies like 3GPP six months to a year to establish a new set of test cases for conformance testers. Once those test cases come out, there’s a flurry of activity while operators, device manufacturers, OEMs, and others attempt to verify compliance and interoperability with new and existing standards. The fact that it takes 3GPP a fairly long stretch of time does very little to lessen the time pressure that testers usually face when it comes to performing each new round of service verification.
