Hello All,
I've been reading articles here for some time (and forums too) and finally decided to subscribe. You guys are doing great job here!!!
Preface:
I'm a professional software developer (mostly high performance servers and networking). Recently I had a project where I had to develop a system to manage wireless sensors (large amount of them). Part of the project was to choose and deploy wireless access points. People I was working with claimed that they can buy $30-$100 ones at Frys/Newegg and run with them. I was very skeptical.
Test:
They bough like 10 different ones and tested them like this: a dozen of G wireless clients connecting to the wifi access point, and accessing an HTTP server every minute or two (simple HTTP GET).
Results:
Not a single access point could reliably pass the test. Issues encountered:
- Unreliable dhcp servers (can't get IP address)
- weird delays in getting a wifi link (200ms usually but can take up to 2-3 seconds, probably due to WEP/Security?)
- hanging up, requiring a hard reset
- signal dropouts (can't get a wifi link)
Proposal:
Devise a test which can stress test access points for at least a week by simulating a dozed of wifi devices with different patterns:
- frequent on/off, requiring a wifi link negotiation several times an hour
- ocasional file transfer (max bandwidth)
- movie watching (mid-level bandwidth) but for 2 hours
- web browsing (bursts of traffic with several tcp connections open)
etc
