Speed question: 3G via Bluetooth

[Sig_ZA]

AFAIK bluetooth has a maximum speed of 115Kbps and 3G 384Kbps.

1) So if I network my 3G cellphone to my laptop using bluetooth, is my interent browsing speed limited to 115Kbps?
2) Or does the phone still download at 384Kbps and like buffer/cache the data, sending it to the laptop at 115Kbps?
3) If 1 above, will similar limitations exist using a USB cable?

Depends on the Bluetooth version...
Earlier versions had a max speed of 723.1 Kbps AFAIK, newer Bluetooth devices can reach 3Mbps...

See http://en.wikipedia.org/wiki/Bluetooth for more info...

USB version 2.0 transfer rate = 480Mb/s
USB version 1.1 transfer rate = 12Mb/s

(Above info as per package insert of a Sahara memory stick)

So, a USB cable won't be hindering your data speed anytime soon

Be careful when comparing speeds, especially the difference between kilobits/s (kb/s) and Kilobytes/s (KB/s).

3G is 384 kb/s (48KB/s), whereas Bluetooth is either 1Mb/s (1024kb/s or 128KB/s) or 3Mb/s.
Using bluetooth to connect to 3G will have no effect on your actual 'speed'

@LandyMan
Thanks.

So Landyman does 115.2 kb\s equal to 14.4 KB\s?

Not all USB 2.0 branded devices support this high transfer rate ... sadly most 3G phones fall in this category.

Though Hi-Speed devices are commonly referred to as "USB 2.0", not all USB 2.0 devices are Hi-Speed. A USB device should specify the speed it will use by correct labeling on the box it came in or sometimes on the device itself. The USB-IF certifies devices and provides licenses to use special marketing logos for either "Basic-Speed" (low and full) or High-Speed after passing a compliancy test and paying a licensing fee. All devices are tested according to the latest spec, so recently-compliant Low Speed devices are also 2.0.

Yep, that is correct. there are 8 bits in 1 byte
