Early versions of connected devices were exactly that – machines connected to machines and sensors via cables. The advent of wireless IoT connectivity options, such as 2G, opened the innovation floodgates for devices to operate in an untethered manner, sparking applications ranging from senior GPS tracking devices to remote agricultural moisture IoT sensors.
And while T1 lines and the early excitement around DSL hinted at hopes for higher-bandwidth IoT applications, the limitations of physical connections, such as Ethernet cables, were not alluring to the emerging mobile-first culture. The future had to be wireless. And although Wi-Fi proved to be an excellent solution for some devices, its many limitations and liabilities relegated it to second-choice status for some and a complete non-starter for most.
Hence the emergence of reliable, ubiquitous cellular connectivity for IoT devices that continues to drive steady innovation in the IoT. 2G devices were rapidly outpaced by the promise of 3G connectivity, but exciting, bandwidth-hungry solutions now demanded something more. LTE is the answer.
