LTE Cat 1 modules with VoLTE support from u-blox certified by AT&T

February 02, 2017 // By Jean-Pierre Joosting
Swiss company, u-blox will provide the first LTE Cat 1 modules with voice over LTE (VoLTE) support to be certified for the AT&T cellular network. The TOBY-R202 and TOBY-R200 modules will support a broad range of Industrial Internet of Things (IoT) applications.

Both cellular modules operate on LTE bands 2, 4, 5 and 12. In addition to VoLTE, they also feature voice support via circuit switched fallback (CSFB) for legacy 2G and / or 3G networks in areas where LTE is not available. TOBY-R202 provides fallback on 3G bands 2 and 5, while TOBY-R200 provides global 2G and 3G fallback.

Voice is key to IoT applications that require command, control and alert functionality. VoLTE provides voice capability on LTE modules, enabling devices of the IoT and their users to easily communicate verbally over the LTE network.

The two u-blox TOBY-R2 LTE Cat 1 modules support a myriad of IoT and M2M applications requiring voice over the LTE Cat 1 network, such as smart home and buildings (alarm panels, security systems and video surveillance), connected health (patient monitoring and stay-in-place solutions), automotive emergency handling and roadside assistance, smart payments (POS systems, connected vending machines, ATMs, etc.), wearables (action cams), and smart metering (electricity and smart meter gateways).

Both modules come in a compact 24.8 x 35.6 mm form factor. Thanks to u-blox nested design, migration between the TOBY-R2 modules and other u-blox 2G, 3G and 4G modules is easy, while enabling future-proof, seamless mechanical scalability across technologies.
