ro.ril.enable.3g.prefix=1
ro.ril.hsupa.category=5

save the file

reboot so that the settings take effect

Stampere suggested this over in Paul's thread with no replys. The hxspa and gprsclass are not included in the Froyo build.prop anywhere I can see. They were included in CM 5.0.6.

Has anyone added these to Froyo and do they help or are they unnecessary and will conflict with the new Froyo 4.0.6 radio build?

My froyo image has none of these and performs well. I can get higher throughput by adding Code: ro.ril.hsxpa=2 ro.ril.gprsclass=12 But the rest are largely undocumented and should remain at default unless someone can prove what they do. The biggest issue is the radio. With Froyo, my 3g disconnection issues are GONE, so now we can focus on latency and throughput. REPLY

This is my point exactly. While I'm still getting some Edge flipping on Froyo radio in weak signal areas like work building, if the throughput is higher then why not add it? I don't think it can hurt anything

The rest are "relatively" undocumented as Cyanogen said he didn't know what they did, therefore he wasn't going to mess with them. My 2 thoughts were:
(1) If throughput were increased, would power consumption decrease as data would be transmitted and completed faster...or
(2) Would adding additional code lines conflict with the current image somehow as they were obviously left out on purpose?

I too have better connection with the froyo radio - but weak throughput. I'll research and try some of these and report back if I find anything positive. REPLY

I added the hsxpa and gprsclass entries to my build.prop and will test also when I get out of work into a 3g environment, lol. I had modded this in CM 5.0.6 and played with hsxpa settings of 1 and 2. 1, I believe is WCDMA preferred and 2 is universal or something like that...
