Conduct a web-search for topics relating to 5G and on many occasions the answers which get returned are nothing to do with the next generation of mobile services, but relate to 5 GHz, which is one of the frequency bands used for WiFi (as well as several other technologies). It seems that both terms being of a wireless nature, those clever search engines are yet to be able to fully distinguish between them.

But there is more... If that isn't confusing enough, there's also a technology known as G5 which is designed to perform the job of allowing vehicles to communicate with each other, known as vehicle-to-vehicle (V2V) communications, and with infrastructure (such as traffic lights) known as V2I. And to really throw the cat amongst the pigeons, the frequency band used for G5 is 5 GHz (5850 - 5929 MHz). Got that?

So, just to be really clear and helpful in exactly the way that Wireless Waffle always isn't, here are some bullet points which don't make everything far more translucent:

• 5G is the term used for the next generation of mobile technologies which will follow after 4G (LTE). The technology involved is also known as New Radio (NR).
• 5 GHz is a range of radio frequencies often considered as being 5150 - 5925 MHz, which are used by a wide variety of applications including WiFi, 4G (including LTE-U, LTE-LAA and MulteFire) and G5.
• G5 is a vehicle communication technology designed to enable Intelligent Transport Systems (ITS) such as autonomous vehicles.

And now you know. So if Mr Google comes a-calling to this here web-page, hopefully he will be enlightened and future search results will no longer confuse these very different technologies!
