By 2026, procurement managers in Advanced Metering Infrastructure (AMI) can no longer buy for today only – they must ensure hardware stays relevant through network sunsets and new frequency bands over the next five years. 2G is being phased out in some regions, 4G LTE Cat-1 bis is expanding rapidly, and 5G standalone is emerging in early-adopter markets. A Data Transfer Unit that fails to handle all these generations becomes a single point of failure.

Tespro has engineered its industrial-grade DTU family to deliver uninterrupted connectivity from 2G to 5G – no dead zones, no manual reconfiguration, and no need to wait until 2030 for another upgrade. The unit supports 2G, 3G, 4G, and optional 5G modules, automatically switching between bands and operators worldwide.
Real-world example: A water utility in Southeast Asia still relies on 2G for 70% of its meters but plans to migrate to 4G by 2028. Tespro’s DTU runs on 2G today. When the operator refarms spectrum, the same hardware upgrades to 4G via a simple mini-PCIe card swap – no truck roll, no enclosure replacement.

- In Southeast Asia where 2G remains the dominant coverage, will this DTU work reliably?
A: Absolutely. Tespro DTU supports 2G bands such as GSM 900/1800 and includes automatic fallback. In countries like Indonesia, the Philippines, and Vietnam where 2G is still active, the unit will collect and transmit data without issues. When local operators later re-farm spectrum to 4G, you can upgrade the communication card – no need to replace the whole DTU. - My project spans multiple European countries with different carrier bands. Can one DTU model work everywhere?
A: Yes. Tespro’s frequency library has been pre-tested with major European carriers including Vodafone, DTAG, and Orange. You can select the appropriate frequency profile per country on the cloud platform, avoiding the need to purchase different DTU models for each nation.
In a fragmented 2026 network landscape, choosing a Data Transfer Unit that spans 2G to 5G is not about future-proofing – it’s about staying operational today. Tespro’s industrial-grade DTU eliminates the risk of silent meters when networks shift.
