The question of what time will it actually take to send or receive a 1MB file will only be answered when these thingys are in the wild and are clocked sending/receiving data while connected to actual infrastructure.

My dream phone is not a portable WIMAX bridged to a 2.4Ghz 802.11b/g hotspot with only 3 available WiFi channels but instead I want HSPDC+ bridged to to 5 Ghz 802.11n hotspot. Until then I guess I’ll tether.

There are 1000 bits in a kilobit and 1000 kilobits in a megabit.

Therefore, there are 1 million bits in a megabit.

The conversion from bytes to bits works like this, and beware, this is long handed…

1 byte (B) = 8 bits (b)

Since we are dealing in 1 million bytes or bits ( mega ) we will apply the same conversion.

10 megabytes = 80 megabits

A 1 megabit per second connection can transfer 60 megabits in a minute and 80 megabits in 1 minute and 20 seconds.

Since 10 Megabytes is 80 megabits, we can transfer 10 megabytes over a 1 megabit connection in 1 minute and 20 seconds.

This of course does not factor in anything but the pure math. This leaves out network overhead, distance, the speed of
the opposite connection, etc

Now, save yourself some time and use a calculator :-)

To equate this to your 4 megabit connection, 4 megabits is 4000 kilobits so you can handle approx. ( 31.25 ) 128 kilobit streams.
Again, this doesn’t factor in anything but the speed rating.

I’m assuming that they should have titled it the first phone to support up to 14mbps download. Because if I take my N1 onto the HSPA+ network HTC states:

HSDPA/WCDMA:
900/AWS/2100 MHz
Up to 2 Mbps up-link and 7.2 Mbps down-link speeds

7.2/2 is good enough for me. Most phones’ browsers wont even be able to load that fast because of the RAM limitations anyway.
