LTE categories 2, 3 and 4, from release 8, were designed for the higher bandwidth demands of consumer cell phone users. One can see the increased data speeds and technological complexity in the chart on this slide. At the same time, CAT 1 was defined as the first solution targeted at lower bandwidth applications. With release 12, the new CAT 0 specification has been released and the movement to support even lower bandwidth connections on the LTE network has begun. Why is this important? Previous advancements from 2G to 3G and then to 4G all required new infrastructure and different radios in the devices. A phone that was LTE but could fall back to 3G and 2G had to have either a software defined radio, or separate radios for each technology. That added complexity and cost to the design. With CAT 1, the underlying network infrastructure is still LTE, so the device only needs a single radio. Also, because they are designed for lower bandwidth connections, the design is significantly easier, resulting in a lower cost device.
