The document discusses wireless connectivity options for device-to-cloud applications. It compares different wireless technologies like LTE-M, LTE Cat M1, and LTE Cat 0-6 in terms of speed, power consumption, bandwidth, and rollout timing. LTE Cat M1 offers the best combination of low cost, power efficiency, coverage enhancement, and speeds from 300kbps to 1Mbps. It is expected to see initial rollouts in 2016-2017, followed by mass build-out from 2017 onwards, making it very well suited for applications requiring long battery life and deep indoor coverage like package trackers, security systems, and industrial sensors.
