Companies are doing the baseband processors because that is the easy part. Buy an Arm core, which is what everyone wants to use, integrate some peripherals and you can offer something. The major companies are doing their own apps processors but they are having problems with the modems. The hard part is the complexity of the modem and the software protocol stacks that go with it. You can find companies that will develop a protocol stack for you but don't expect it to work as advertised.
I think many of these baseband IC companies you are spotlighting, plan to get some hardware ICs out there and hope somebody writes some software to go with it. Good luck with that. You're going to be staring at your pretty hardware ICs for a couple of years.
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.
