£2k for a managed solution is not a lot of money, compared to around half that for an unmanaged one that could handle nowhere near the traffic and would be nowhere near as future proofed.

I highly doubt your real world testing actually works as previously stated in this thread.
Not many yet. But as new models all support N (such as the last dozen we bought, and the next dozen we're going to buy), a system that supports future technologies is probably a good one don't you think? Becta advise schools to use Cat6 cable to the client now for new installs. 802.11n is the equivalent in wireless tech...
How many laptops in your school, or perhaps his school are 802.11 N compatible for a start.
Please don't be so silly. You know full well how wireless solutions end up being used. Some areas with far higher client counts than others. For example, covering a sports hall, or ensuring playgrounds are covered - doesn't help most of the daily use but adds to the AP count.
And you fail at real life references as well 30 AP's supporting 40 laptops and then failing to support 120, thats "four" devices per access point.
Trundling must be the word! There was a document posted on here recently, comparing different wireless solutions - they showed quite well the different capabilities of different solutions.
We have 30 in a classroom with a single £60 access point just trundling away..
I'd love you to show me an unmanaged wireless access point (in a/b/g) that can handle 30 clients reliably. 54Mbps between 30 clients. 1.8Mbps each, minus overheads/collisions. Say those overheads are 0.3Mbps equivalent, that leaves 1.5Mbps. However, that 0.3Mbps deduction is unrealistic, as collisions are the main problem on AP's.
Using a D-Link DWL-2100AP as an example (a bog standard, cheap, unmanaged, AP I hope you'll agree), we managed to get a total of 9 laptops logging on to it within a reasonable time - adding more ended up with the entire lot talking a huge amount of time (I'm talking 10 minutes for 10 laptops to log in and receive their 10MB mandatory profile). This problem was the exact reason why our school's bursar was so hesitant to invest in any form of wireless system, as they'd been sold a pup by a previous supplier when they'd stated a single 54Mbps AP could support 16 laptops in one go.
Investing in 2 trolley's of laptops because you expect your wireless system to handle it, then finding it can't is not something schools should be doing...
