I don't know what happened to the C5 - still vaporware 18 months after announcement.

The lack of 5Ghz in all their products is... surprising... There are plenty of home users with 5Ghz only networks, which in turn means anyone designing an IoT device will get user complaints and returns from all these users.

  >There are plenty of home users with 5Ghz only networks really? is this a configuration that some ISPs are shipping in their routers, or how is this happening? i've never heard of anybody with a 5GHz only home network.

    It's certainly somewhat common for more tech savvy folks to go out of their way to ensure their devices use 5Ghz when compatible. But ISPs? Router manufaturers? No way in hell, why would they self-impose additional support burden by preventing the customer from connecting their 4-5yo old low-end laptop or their shiny new smart bulbs or their brand new Amazon Kindle?

  That's an odd configuration, because having a 2.4 GHz network that all the shitty IoT devices can be on is one of the best remaining uses of that band.

  2.4 is still the best choice for range and penetration (through walls etc.) if you don't need the speed of 5ghz. I'm honestly surprised if they're shipping 5ghz-only consumer access points.

  > The lack of 5Ghz in all their products is... surprising... Is it? Are there any competitors in the class have 5ghz support? Most of the radio MCUs I've seen are all 2.4ghz which includes thread/zigbee/wifi/etc. Every IOT device I've ever seen is 2.4ghz

To be fair, Espressif aren't the only ones. SiLabs announced the SiWx917 eons ago, and they finally appeared on Digi-Key like 3 weeks ago, but only in bulk, and the only dev board available is $200, and no Zephyr support, and this, and that...

  Interesting, thanks for reminding me about that one. 5ghz is pretty rare for IoT chipsets

    You can get it, you just have to go with an external module strapped to a common microcontroller. Infineon's Airoc chips are a good example.
