The Unified Form Factor Family is comprised of 2G, 3G, and 4G, 3GPP and 3GPP2 products sharing a common form factor as well as electrical and programing interfaces which allows developers to implement a "design once, use anywhere" strategy.
All products in the family have the same size, shape, connectors and software interface. The advantage for you is that all products in the family are interchangeable. Telit’s family concept ensures long-term availability of products irrespective of lifecycles of their base technology.
The xE910 family features a single compact 28.2x28.2x2.2mm LGA form factor interchangeable on any regional cellular network. xE910 modules are available in GSM/GPRS, 1xRTT, EV-DO, UMTS/HSPA, HSPA+ and LTE – with certain models featuring embedded GNSS receivers.
