TOBY-R2 Series - Multi-mode LTE Cat 1 modules with 2G/3G fallback

u-blox TOBY-R2 series of multi-band LTE-FDD modem modules, with DC-HSPA+ for 3G fallback in areas with marginal LTE coverage.

u-blox TOBY-R2 series modules support multi-band LTE-FDD in a very small LGA package. The modules are ideal for applications that are being upgraded to LTE from 2G and 3G, due to the long term availability and scalability of LTE networks. 3G fallback is also provided for areas with marginal LTE coverage.

Offering a range of interface options and an integrated IP stack, the modules are designed to support a wide range of data-focused applications and are for medium speed M2M applications, such as smart energy gateways, remote access video cameras, digital signage, telehealth and telematics. The TOBY-R2 also supports Voice over LTE (VoLTE) for applications where voice is required such as in security and surveillance systems.

Easy migration from u-blox GSM/GPRS, CDMA and UMTS/HSPA modules maximizes the investments of customers, simplifies logistics, and enables very short time-to-market.

USB drivers and RIL software for Android are free of charge.
