LTE CAT M1/CAT 1: Ideal Replacement for the Aging 3G/2G

3G is going away soon. Verizon Wireless has stopped activating any new CDMA devices and plans to sunset its CDMA 1X network (1X/EVDO, 2G/3G) on December 31, 2019. Featuring better technical features than 2G/3G, as well as low cost and low power consumption, the FB02 CAT M1 and FB23 CAT 1 pre-certified modem provides an easy path for LTE migration.


● LTE CAT 1: 10 Mbit/s Downlink and 5Mbit/s uplink, ideal for M2M/IoT

● Lower latency, better performance in various applications

● Low power, extended battery life

● Future proof, easy migration  

Ultra-small Form Factor & Simple Integration

The FB02, FB23, FB38 are the smallest in the InHand IoT modem family. The small footprint and other physical features provide flexibility for customers to conduct the integration.  

● Dimension: 46mmx30mmx0.4mm

● 4FF Nano SIM card slot

● 2 U.FL antenna connectors
