Security has become a growing concern in the Internet of Things (IoT) industry. Without robust protection, self-driving car networks easily could fall under nefarious control, and sensitive healthcare and industrial data could be intercepted and sold to the highest bidder. Reliable, preemptive security protocols are needed in order for IoT applications to continue to flourish. And one technology promises to be more secure than any other at a price point that remains attractive to IoT hardware and smartphone manufacturers: a security chip no larger than a pencil eraser.

As you know by now, AT&T kept its promise to sunset 2G as of January 1, 2017 and now has made 3G WCDMA (UMTS) HSPA 850/1900 MHz Band 2 and Band 5 the minimum requirement for its network. The reason AT&T, as well as every other carrier, is sunsetting 2G is simple — they need the space. Eliminating 2G enables the providers to refarm their valuable spectrums for 3G and, more importantly, 4G LTE technology, which are proving increasingly vital with the unceasing growth of IoT worldwide.
