As I have previously mentioned I was concerned about the IRDA link being a bottleneck in speed. I just felt my IRDA adapter was extremely slow because even sending my girlfriend's ericsson phone little gif images took real long. Anyways, I've been getting about 19k speed results from different speed tests across the web (in Austin, TX).

I'm now in the downtown Hyatt in Sacramento, Ca and have 4 bars. Here are my results.

Your raw speed was 90689.69 bits per second which is the same as:

Down
90.7 kilobits per second
How communication devices are rated. Kilo means 1,000 and mega means 1,000,000. Examples include 56k modem and 10Mbit Ethernet


Up
11.1 kilobytes per second
The way data is measured on your hard drive and how file sharing and FTP programs measure transfer speeds. Kilo is 1,024 and mega is 1,048,576.

1MB file download
1.5 minutes
The time it would take you to download a 1 megabyte file at this speed.

Now I'm finally seeing these 2.5G speeds that I should be seeing.

Thus, IRDA is certainly not a bottleneck at all. I think the quality of the signal is imperative in performance. The return times are still abissmal (800+ms), but throughput data speeds are very impressive.
