Two days after Sprint shared its IoT network plans, AT&T said it has launched its Category M1 LTE network ahead of schedule. The carrier said it was able to deploy the technology throughout its network via software updates. AT&T had previously said it would launch Cat M1 LTE by the end of the second quarter.
Category M1 LTE caps upload and download speeds at 1 megabit per second. Because the bandwidth and power requirements are low relative to other LTE categories, Cat M1 chipsets are relatively inexpensive and can operate for long periods of time without recharging.
