I have a Cradlepoint PHS300 and noticed something interesting when using mobile data: if I plug my Sierra Wireless USB modem to the PHS300 and connect my laptop via WiFi I get faster speedtest results than if I plug the USB modem directly to my laptop.

This is obviously for the same network, same location (Auckland CBD), around the same time (as in plug to laptop, test, plug to PHS300, text, plug back to laptop, test)...

Also the connection seems to be more reliable.

Interesting.

No, not firmware, but someone commented in my blog post it could be the queueing mechanism for a network interface driver being more efficient than the one used on serial adapters such as the USB. That would make sense.

I was contacted by someone who pointed out CradlePoint 3G routers support WiPipe Technology, as explained in this White Paper: http://cradlepoint.com/files/uploads/WiPipe_Whitepaper.pdf (from http://cradlepoint.com/content/technology).

They claim to use special algorithms to improve performance of mobile connections... If this is the case, perhaps Sierra Wireless or other 3G USB modem manufacturers should get that?
