While many analysts are debating the definitions of M2M (machine-to-machine) and the IoT (Internet of Things), no one is debating that wireless data network applications are growing rapidly.
Many of the predicted next wave of devices will be fixed-location, sensor-based devices sending less than 500 bytes of data a day. Strategy Analytics estimates that this will account for roughly 5 billion device connections by 2022. Even more interesting is their prediction that half of these new applications will come from start-up companies.
These sensor-based applications have some specific requirements, notably: 7-10 year battery life; modem costs under US$10; network fees of less than $1/month; and indoor and outdoor ranges measured in miles, not feet.
Existing cellular networks, especially 4G-LTE networks today, cannot meet these requirements. Here’s why: today’s cellular networks are “always on” so batteries last days not years, power requirements are 10 times more for transmit and 100 times more for standby and cellular hardware and monthly service fees are too expensive.
