alt Hacker NewsWait till you see the number of actual chip vendors.
There is about 3.. Broadcom, Qualcomm and MediaTek. Together they control I believe 100% of wifi chips used in routers and APs. Often it's sold as a package / system on chip so it's also the main cpu.
On the client side there is a little bit more competition but not much.
Client side don't you just add Realtek and Intel? I don't think almost anyone else does wifi chips.
