LTE is the latest in the evolution of cellular service. Its main promise was higher data rates to support mobile browsing on cell phones as they became more of a media consumption device and less of an audio communications device. LTE is evolving as cell phone consumers demand more and more content on their phones and more and more bandwidth is necessary to support them. With the promise of billions of IoT devices in the next decade, the industry is looking to make cellular affordable enough to support many of those devices. Unfortunately, high speed and high bandwidth require high design costs and high hardware costs – not exactly big drivers for adoption in IoT sensor applications. To address this, the industry has created new categories of LTE that are designed to meet the lower cost and bandwidth needs of these new devices.
