LTE Cat 1 modules with VoLTE support certified for AT&T network

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 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. “U-blox is a global leader in developing cellular modules designed for IoT and M2M applications," said Drazen Drinic, product manager cellular at U-blox. "We are pleased to extend our long-time relationship with AT&T to supply LTE Cat 1 modules with VoLTE capability to the AT&T network." “Voice is an important feature to many use cases in IoT,” said Chris Penrose, president, IoT Solutions, AT&T. “The U-blox Cat 1 LTE modules with VoLTE support will offer robust connectivity to many of our customers requiring voice support capability in the alarm and security industry, automotive and connected health markets.” The two 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). The modules come in a compact 24.8 mmx 35.6mm form factor. Thanks to their 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.
