GRABBED AX200 WIFI CARD

Given the headaches with Bluetooth the Intel AX200 has been ordered which has better antennas which may improve connectivity.

The AX200 was released 6 months before the standard was ratified. Intel is a large player and they are not as bad as the fiasco with the 802.11n.

The main change is the support for 20, 40, 80 and 160 Mhz channels. At present there are only 2 channels for 160 MHz operation in the 5 Ghz band. One of the goals for 802.11ax is the available 6 Ghz that is being cleared for mobile and Wi-Fi use.

The Chinese Fenvi manaufactures the logic board and then Intel’s card is installed into the slot. There is a heat-sink on the model selected primarily as it protects the card as well as keeping it cool.

The model selected has a conventional black heatsink but there is another model with a bright red heatsink.

The current WiFi hardware in the studio supports up to 80 Mhz channels. The move to 802.11ax is likely to be slow primarily as existing hardware is adequate.

USB NEEDED

For some reason the Fenvi cards need USB to enable bluetooth. The actual Intel chip can make do with the PCIe lane only, there is not additional connector. This suggest a change in design as opposed to the way a laptop machine is designed. PCIe USB logic is very low cost.

The main issue is that USB 2.0 headers are in short supply in most modern desktops. Cable management is another problem.
