WCET Exam Prep – Introduction

In the beginning of 2017, I made the decision to attempt the IEEE Wireless Communication Engineering Technologies (WCET) Certification.  If you have ever read this blog, followed me on twitter or met me in the last 7 years you will know that I have had my head buried pretty deeply in Wi-Fi as I worked towards my CWNE certification.   But, it also makes sense to keep aware of the other technologies available.

Today we are seeing the emergence of many technologies like LTE-U, LAA that implement LTE on the 5GHz unlicensed bands, LTE-A that will bring the precursors of 5G New Radio to mobile networks, and CBRS & Open G that will allow deployment of LTE on coordinated spectrum in the 3.5GHz band.  In the IoT space we are seeing Sigfox and LoRa cement their positions as preferred IoT protocols in the unlicensed 900MHz band with incredible range and battery life but we are also beginning to see projects using NB-IoT from some mobile operators to enable the internet of things.

Regardless of your opinion on the various emerging protocols above (I have many), it is certainly an exciting time to be alive in the wireless communications space!

Back to the point.

The WCET certification is aimed at the wireless professional with a bachelors degree and several years of work experience in the wireless communications industry.  It covers a huge swathe of knowledge including Fundamental Mathematical Knowledge, RF Engineering, Propagation, Antennas, Signal Processing, Wireless Access Technologies, Network & Service Architectures, Network Management & Security, Facilities & Infrastructure, Industry Agreements, and finally Standards, Policies & Regulations.

This information can quite easily be covered in a series of heavy textbooks.  This will be my attempt to share some of my study notes as I move through the material!

That’s all for Now
