@connorsoliver said in Wireless Network Technologies - CompTIA A+ 220-1001 Prof Messer: Why isn't zigbee used for computers? 802.15.4 (aka ZigBee) has a speed of 250 Kb/s which is SO slow. High enough to make two phone calls, but that's it. Not enough to really "do" anything. It's plenty fast to send sensor data or basic instructions, but way too slow for any computer usage. Old 802.11b, the slowest computer wireless tech, was 11Mb/s, which is 44x faster than Zigbee and considered worthless because it is so slow. We want our wireless in the 100Mb/s+ range these days.

That's actually not all that fast. Fast for a phone, but not for a network link. We have systems implementing 10Gig, 40Gig and even 100Gig regularly (okay, 100Gig is rare still). So 6.8Gig isn't that much. I have a VERY entry level client using 20Gig right now. Internal or external for 20Gig? what are they moving? Internal, external is 10Gb. No idea.

@dbeato - Thanks. Maybe it didn't used to be in red.
