I was explaining why it doesn't match manufacturers' value, which was what you asked.

Were both phones tested at the same time? Does your radio match the RIL (and vice versa)?

Yes, I understood that

They were tested several times, same place, exact same test start.

Not sure how to check that... Is that related to the modem and such?

Ah yeah it's called "modem" for Samsung devices, since XDA search is down...I can't find out atm. But usually, a rom dev will recommend a modem to go with the rom.

My modem is XXKI3, flashed a few weeks ago, from XXKH3. The RIL is stock Samsung (not CM).

So my phone seems to have been getting hotter lately after i switched to CM7, and battery life hasnt been great.

Then I realized i never took SetCPU off of Performance mode locked @ 1.6Ghz when I was benchmarking.

Might explain that

Your carrier, the phone and it's network. The specification quotes a maximum theoretical value of the wireless network's specification. In real life things rarely come close to that value. Examples? Think: home wifi network, USB transfer speed.

Like all things, manufacturers/carriers will always quote the higher, theoretical value to make people think otherwise.

That, verbatim.

You have lab speeds, where you have perfectly ideal testing conditions where 21.1Mbps may be attainable, then you have the real-world which is never anywhere near the lab speeds.

In the real world you have environment (temperature, humidity, foliage, geography, etc), backhaul load (the amount of viable bandwidth in the local ring topo), backbone to backhaul interface (where the cellular backhaul interfaces with the internet backbone, usually a fiber trunk), number of users that the tower has to divide spectrum between (every user that's added to a node decreases the total available bandwidth to every other person that's connected, since there are always minimal QoS requirements), and MANY other factors. Just to give you a sample...

but at home I can get up to 50 down, which is obviously ridiculous for a phone.

50Mbps is a GREAT number for a phone. Without that dual-channel memory interface that's a part of OMAP4 you wouldn't be able to take advantage of that speed. The Galaxy Nexus is an LTE Advanced handset if I'm not mistaken, which puts it at being 100Mbps (duplex) capable.

LMAO, that would do it. Try keeping Tegra 2 stuck at 1.6Ghz... two words: Melted Plastic.

I see... Thanks for the explaining (And thanks again to Johnny aswell!)

But it still remains : why do I get better results on the Xperia Arc S on WiFi, H+ AND GPS? Same test settings, time start...

Every phone has a different antenna setup. And different devices can be set at different HSPA releases.

If you have root on your GS2, what does this say on your build.prop?
ro.ril.hsxpa=3
ro.ril.gprsclass=12

I have mine set to identify differently than what AT&T ships phones with. They ship it at HSXPA=1 and GPRSCLASS=10.

Then again, the SE could be on a different band than your GS2. Since most cellular networks have 3G on two bands (AT&T for example has it on 1900Mhz and 850Mhz, and 850Mhz is usually faster because of less signal noise and degradation).

Hahaha, fixed it now

At least i know the OC is stable lol

Guys I need help with my honeycomb TPT. It will NOT connect to wifi the way I want it to. It's a completely stock TPT, with the latest ota update.

It will connect unsecured w/ DHCP. It will connect unsecured with static IP.
It will connect secured WPA2/AES w/ DHCP. It will connect secured WPA2/AES with static IP.

It will NOT connect secured WPA2/AES with my original 63 char ASCII key. Is there password length issues with honeycomb?

My wifi is managed by a linksys WRT54g v6 router, set to wireless G only, secured by WPA2 Personal/AES (no TKIP) and a 63 char. ASCII password. DHCP is enabled and there are available addresses. All advanced settings are set to default. The only other time I've had an issue with this is my xbox360, where for some reason it wouldn't take the entire password, but so I increased the password 10 chars at a time until it was the full length/original and oddly enough it connected, I still don't know why! I can shorten my wifi ps length if need be but it will be pain because I have tons of devices I would have to change. Any insight? I know this isn't a help me thread but I figured all the android geniuses would be in here. This is my first tablet and my first android device in a long time.

Ummm... I don't have those entries

Examined the build.prop twice, didn't find anything related to the RIL
