Wireless / Cable Speeds.

HSPA+: 21 Mps theory max (I get about 7-8Mps )

LTE: 150 Mps theory max (10-35Mps typical)

802.11n 25-33 Mps (300Mps theory max)

802.11g  20 Mbps avg

802.11b  5.5 Mbps avg

10 BaseT 10Mbs theory max

100 BaseT 100Mbs theory max

Gigabit 1000 max 890Mbps (up to Hard drive limit)

The thing they don't really tell you is that Theory max really is just a theory, you have overhead / convert to Bytes.. (divide by 8) your Mbps doesn't look as nice. Generally you get about 50% of the maximum rating assuming you haven't already maxed out your channel or the technology like a celluar antenna is within decent range and isn't overloaded with people just like you.

Also keep in mind it's not only download speeds you want.. it's upload speeds and they are typically horrible even in wired situations..

because of the new broadban abilities it's recommended that you use this http://www.terago.ca/speed-test/Default.aspx as it's capable of up to measuring 100MBit.. (like you can afford that lol)

to give you actual bandwidths that can be expected by various technologies.
