The Internet of Things (IoT) is a business enabler and a global success story. As a matter of fact, we now have smart connected IoT endpoints which are allowing us to monitor and control remote locations or objects. IoT solutions can replace inefficient manual processes, save cost and improve quality. But beyond existing use cases, IoT techniques can be used everywhere, and business opportunities are unlimited.
Most IoT applications and rollouts require tailored endpoint devices involving remote sensors and actuators according to use case requirements and dedicated “edge” processing capabilities. Very often, only infrequent small data packets need (monitoring, control) to be transferred back and forth, but in any case, selecting the most appropriate connectivity technology a key aspect for the design of an endpoint device.
Benefits of Cellular IoT
Several wireless technologies are available incl. WiFi, ZigBee, Bluetooth, etc. Most of them are for on-site use only (LAN – Local Area Network), typically with a building, e.g. at home, in offices or in production environments. Cellular networks – based on 3GPP standards like LTE – work differently, and they are offered as a payable service.
Key differentiating aspects are:
- Available everywhere, due to strong transmission power of network cells of up to 40 watts (for macrocells), long distances of several kilometres can be covered over the air. This long reach capability also works for installations inside a building or under ground – to be accessed from outside.
- Global reach: works (almost) everywhere on this planet
- 100% Reliable – always available, stable and up-to-date
- Well-balanced TCO (total cost of ownership):
- (minus) pay-per-use model or subscription plan
- (plus) managed by professionals, maintenance-free
- (plus) no need to buy or install or to maintain network equipment or infrastructure
- Independent operation, does not rely on cooperation with an existing network (e.g. a wireless LAN) at the point of deployment
