In mainland USA XM / Sirius uses COFDM towers in urban areas to overcome loss of satellite links due to high rise buildings.
But the quality of COFDM goes a little beyond good video quality. It also affords better penetration into buildings. Though Sirius / XM is basically an audio service, the digital stream allows video streaming to back seat passengers or hotels / motels can use it to distribute video within their facility.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
