900mbit Wireless Laptop Adapters

Hi All,

We have a couple of AP135 and want to use them to their full potential. We currently only have 300mbit compatible cards in our laptops. Can anyone recommend 900mbit cards that they have tested?

Thanks
James

Cheers
James

Re: 900mbit Wireless Laptop Adapters

I'll let others respond with client card recommendations, but the maximum over-the-air datarate you can expect from a 3x3:3 11n MIMO radio is 450Mbps (MCS23); a 50% increase from the 300Mbps you can get from a 2 stream version (MCS15).
The AP-135 is a dual radio AP, so the theoretical aggregate max is 900Mbps, but the per radio (and per client) max is 450Mbps. Note also that in most pracatical deployments, the 2.4GHz radio is limited to HT20 (20MHz bandwidth) operation, which cuts the max throughput in half.

Check out the following. This would only work for desktops

 

ASUS 4x4 802.11AC Wireless-AC3100 PCIe Adapter (PCE-AC88)

 

This is a 4x4 AC wave 2 adapter. This is the fastest card i have seen, but i have not personally tested it yet.

Re: 900mbit Wireless Laptop Adapters

As Onno mentioned maximum througtput depend on a couple of things. 

  • Modulation mode
  • Datarate
  • Spatial streams
  • channelwidth/bonding 20mhz,40mhz,80mhz,160
  • Guard interval
  • RSSI signal strength / SNR ratio

In most office deployment channelwidth to 5ghz is set to 40mhz to can greate a good channelplan without overlap (co-channel interfernce) also note WiFi is half-duplex.

 

Take a look at the MCS index for a good overview.

Also note that modulation datarate isnt your real throughput, due of re-transmissions, waitingtimes, interference, etc. you should normally real throughput arround half of the modulation datarate.

 

Also note that the Aruba AP-135 wireless AP, 802.11a/b/g/n, 3x3:3, is not 802.11AC compatible and not MU-MIMO.
