I have no idea if the numbers you are quoting are accurate, but I'm confused by your mixture of different units.
Trying to compare similar units:
Wireless: 2 MB/s to 108 MB/s is an increase by a factor of 54.
LAN: 10 Mb/s (1.25 MB/s, disregarding whatever the framing overhead is) to 1000 Mb (presumably per second, 125 MB/s) is an increase by a factor of 100.
Telco: 1200 bps (120 B/s, assuming 1 start bit and one stop bit, or 0.000120 MB/s) to 24,000,000 bps (24 Mbps, or 2 MB/s) is an increase by a factor of 20,000.
So what conclusions are we supposed to draw?
1) Communications speeds on copper wire via telco have increased way more in the last 10 years than either LAN or wireless technology, and telco is now at the point where wireless was 10 years ago. LAN has gone from being 63% as fast as wireless to being 16% faster.
My reaction to this claim: Frankly, I have trouble believing those numbers, and I think I would want to double-check them.
2) If we assume that all 3 keep up their rates of increase, we should expect to see, in 10 more years:
Wireless: 108 MB/s x 54 = 5.8 GB/s
LAN: 125 MB/s x 100 = 12.5 GB/s
Telco: 2 MB/s x 20k = 40.0 GB/s
My reaction to this claim: I don't think the assumption is valid that all 3 technologies will continue at their present rates of increase. Specifically, I find the conclusion that, 10 years from now, telco will be more than 3 times faster than LAN, to be incredible.
Did you want to back up those numbers, maybe put everything in the same units to make it easier to do comparisons, and/or explain what conclusions you ARE trying to draw from these numbers?
