ByteSnap Design, an embedded software and electronic product development consultancy, has launched a cellular migration fast-track service to help device makers complete 4G LTE and 5G transitions more quickly.

With 2G and 3G network shutdowns already complete across major markets, manufacturers are under pressure to migrate legacy connected products to avoid disconnection risk. Despite their capabilities, some manufacturers lack the in-house experience for specialised disciplines such as RF design, certification knowledge and navigation, and modem integration, or the test lab relationships, to do so efficiently.

UK firm ByteSnap Design’s service compresses what typically takes internal engineering teams 12 to 18 months into a four-to-six-month delivery window, covering antenna redesign, firmware updates and end-to-end certification management. The service draws on ByteSnap’s track record of more than 50 completed cellular migrations to support manufacturers and reduce lost time, and the associated costs that may occur, for each failed certification attempt.

The company holds NXP Gold Partner status and ISO 9001:2015 certification, and has established direct relationships with test laboratories to help accelerate the entire certification process.

“The sunsetting of 2G and 3G networks has created a genuine minefield for companies developing embedded products,” said Dunstan Power, director at ByteSnap Design. “It’s no longer just about hardware; manufacturers are facing a complex choice between multiple migration paths while simultaneously navigating new compliance headaches like the Cyber Resilience Act (CRA).”

He said the service should help streamline and accelerate the cellular migration pathway.

“By plugging our specialist connectivity capability into an existing team, we can resolve the technical uncertainties that cause projects to drift, helping manufacturers move from a stalled prototype to a production-ready launch in a matter of months,” he said. “We offer end-to-end engineering support from firmware development, PCB design, right through to production.”

The service has a three-step process: a migration readiness assessment completed within three to five days; a full fast-track execution covering hardware redesign, antenna optimisation, firmware updates and certification management over four to six months; and a certified product launch, where manufacturers receive their product-ready design and complete documentation.

Manufacturers requiring long-term compliance management support can also make use of ByteSnap’s optional ongoing CRA support services, including SBoM management, targeted OTA update releases, quarterly obsolescence monitoring and priority fast-track access.

The company has previously guided an EV charge point manufacturer through two successive cellular standard migrations: first to LTE Cat-M1 with 2G fallback, then to Cat-1bis for expanded international coverage, enabling the client to consolidate its market position and expand into new territories.
