CutiePi – A Raspberry Pi 4 tablet

Re:CutiePi – A Raspberry Pi 4 tablet by aboringusername on Sunday March 21, 2021 @09:54AM (#26530447)

Looking at the specs [1], I can't help but feel for $200 getting Wifi 4 (N, from 2008) and BT 4.0 (from 2010) leaves me underwhelmed. Maybe it was a cost decision, maybe licensing? Maybe due to power constraints? But damn, Wifi 4 is just objectively terrible and needs obliterating, it's borderline unusable and leaves me worried about the longevity of using such old standards in 2/3 years time (if that's the expecting lifetime of the product)

Care to elaborate a bit on why ? I have been using n for years at home and at my office without any problems. It seems much faster than b and g which I had before.

Primary issue with N tends to be client density, secondary speed, but really both are related anyways. Also the compute module is single antenna, most N devices were at least 2x2 which doubles the throughput. I.e. expect 100 Mbps half duplex throughput to be a "very good" connection on such a device.

That being said the device actually supports WiFi 5, the page just seems to be out of date. Still only 1x1 though which is the bigger travesty.

Many older Thinkpad Models still have WiFi N, it's not that bad as you describe it.

Worth noting that WiFi 5 is 802.11ac, which only applies to 5Ghz; any WiFi 5 gear is using 802.11n for 2.4GHz. (Edit: Pi 4 can do 5GHz) One wonders if they skipped doing a 5GHz antenna for cost/space/other reasons.

I'm kind of confused but by research [1] says the CM4 they've selected does indeed support wireless AC and BT 5.0 LE

I wonder if they just recently decided to go with the CM4 module and failed to update the specs to match. The video shows them using the CM3 module, which does have lesser wifi/bt specs.

There was a previous version of this tablet using the CM3 with wifi/BT hardware on the carrier board, they probably just forgot to update that part of the specs page. The new carrier board does not have wifi so they are definitely using the CM4's onboard wireless hardware.

Probably you will be able to switch raspberry 4 compute module to raspberry 5 when it came out. No guarantee of course but probably slot will be the same.

Wifi 4 is more than fine.
