Cellular IoT is one of the most common forms of IoT connectivity for a number of reasons. It has vast coverage, works pretty much out of the box, supports low- and high-bandwidth applications and is a relatively cheap investment. But what about those remote or tough to reach locations, where critical data for a raft of industries from utilities and renewables through to forestry and wildlife tracking are not covered by cellular coverage? One of the biggest challenges cellular IoT specialists face when implementing satellite IoT connectivity is learning to throttle back on data requirements. It’s too expensive and too power hungry to try to use satellites in the same way that you would use a terrestrial network. But if you know what to expect, you can plan accordingly, and save yourself time and money in the long run. Here are four key considerations to set you on the right path. Data Optimization When 90 percent of IoT sites have been connected with cellular, but the final 10 percent are out of cellular coverage, you may be left with satellite as your only option. This is common, and the first hurdle is the volume of data you’re expecting to push through a satellite connection. As more and more IoT devices use up more and more bandwidth, even in cellular IoT, developers are being encouraged to be more circumspect with how much bandwidth they truly need. This is an acutely important consideration in satellite IoT. Satellite network operators (SNOs), similar to mobile network operators (MNOs), have a limited amount of licensed spectrum. In addition, they have satellite masts that are really far away, and they consequently charge a relatively high premium for utilizing limited capacity. Cost, therefore, is a major incentive for systems integrators and developers to start thinking about how the amount of data sent over Fulfilling the Parts Cellular Cannot Reach Demystifying Satellite IoT By Alastair Macleod MOBILE & WIRELESS 16 THE CHANNEL MANAGER’S PLAYBOOK
