Sure, Internet of Things (IoT) is great. It’s easy to see the potential benefits of data mining and better analytics. None of that makes it easy to implement. IoT networks tend to be large in both size and throughput, and it presents plenty of challenges from the design standpoint. One of those challenges is incorporating older equipment into IoT networks without spending a fortune. For a while, 2G and 3G worked well for many networks, but major carriers are phasing them out. LTE Category 1 (Cat 1) is a replacement for legacy 2G and 3G. Cat M1 and NB1 are not far behind. These new, low-bandwidth technologies help many IoT networks expand capacity for surprisingly little money. Continue reading…

How to Improve Security with IoT Intranets

Antaira APR-3100 Industrial Access Point

Everyone loves to rave about the benefits of the Internet of Things (IoT).  However, few people appreciate the demands IoT systems bring to the table. Cost management and network design are hard enough, but the bulk of IoT field devices operate at minimum power and data flow. Many were deployed in control and automation facilities decades ago and support only simple communication functions.  This creates a unique security challenge. IoT can force a designer to incorporate anywhere from hundreds to millions of endpoint devices without being able to secure them on an individual basis. There are many approaches to solving this problem.  One feasible solution is to create private networking layers to minimize risk without spending exorbitant amounts on each IoT device.
