Verizon 4G LTE Speed Test Results: POST EM' HERE!

[Guest 214]

You mean Cat. 2.

Yea. It would be nice if phone makers published what cat their handset's were. Wonder if the Galaxy Nexus will be 3?

[Icyhot1966]

Which phone has the highest cat #, and where could you find that info out?

[RCtennis3811]

Yea, Motorola LTE Wrigley chipset's only are Cat. 3. chip's which max out at 51mbit/s downlink and like 25.5 uplink

Good to know! I honestly thought they all had the same theoretical limit!

Yeah Verizon's Galaxy Nexus has Samsung's own CM221 a revision of the baseband that appeared in Droid Charge (CM220). It's definitely category 3 UE. Also using the same VIA CBP 7.1 CDMA baseband.

"static struct modem_data lte_modem_data = {
.name = "cmc221", and /* cdma target platform data */
cdma_modem_data = {
.name = "cbp7.1",

Ugh. My Droid Charge was terrible at locking onto any signal (3G or 4G). I hope they have those problems worked out by now.

Verizon 4G LTE in Birmingham, AL w/ an LG Revolution


vs. AT&T *4G* on an HSPA+ 21 capable handset (HTC Vivid)

Agreed. I remember the Droid Charge reviews were all terrible about signal reliability. milan - can you find the source code that tells which baseband and radio is used in my Samsung Stratosphere? Not sure where you found that, but it would be mighty handy to know. I am a programmer, so if you want to just teach me to fish, I can find it myself.

Thanks,

I thought the Vivid was only HSPA 14.4?

this doesn't answer your question fully, but: http://www.samsung.com/us/mobile/cel...05LKAVZW-specs

Processor Speed, Type VIA CBP7.1 + CMC220(LTE) + AP (S5PC111, 1GHz)

I'm having a lot of 3G problems with mine. data will usually work on 4G, but if it loses the 4G signal and drops to 3G, the green up arrow will light up for a few seconds, then go gray, and repeat a few times before going dormant. so web pages or any other data may take minutes to load, if ever.
all i can assume is the phone drops 4G, then tries to use 3G from that tower (which is a fair distance away, when the closest tower with 3G stopped working for a short time one day my signal was -103 dBm) and fails.

here's a decent upload (near airport):

No. It's actually HSPA+ 42 capable from the baseband specs.. An uninformed blogger reported incorrectly it was 14.4

Sounds really buggy. I haven't seen that specific problem yet, but it sounds radio related - and I suspect my problems are also within the radio. I found some articles claiming good performance from the CMC220 in the Droid Charge as well - I can confirm that I can get good results from speed tests 10-15Mb/sec usually - I've seen upwards of 17 Mb/sec a few times. Totally respectable and acceptable to me in terms of 4G performance on a phone. My main issue has been that even in the presence of rock solid signal, it will still randomly drop 4G and go to 3G or even 1X! Then later it switches back. I know signal is great because my Xoom tablet is showing 4G signal is usually 4 bars (maximum) in the control area, but flickers down to 3 bars occasionally. Xoom never drops 4G, but the phone is bouncing all around like a circus animal.

It seems, sometimes the roller coaster is too much for it and the reconnection attempt just fails and the Internet connection is dropped entirely leaving my push e-mail and background Twitter updates/notifications not updating which is maddening. I'm only one week away from giving up on the thing and switching back to my Droid Pro until I can get a Droid 4. This time I won't rush out the door and buy until I've heard good stories about the 4's radio. I can't deal with this inconsistent radio performance.

All of those pre existent issues seen on CMC220 devices are gone on CMC221. Verizon's GN baseband performance is rock solid.

In rural OKC metro.

MarkyD and others: awesome speeds! Does anyone have the Nexus yet? I got mine this morning. I told you guys my radio was bad in the Thunderbolt, and holy cow was I right!!

I haven't had time to run that many speed tests yet (saving that for tomorrow) but I pulled these on a site I previously couldn't hit 20mbps at:

5:30 pm

5:29 pm

5:28 pm



And pulled this from another site down the road:

5:48 pm

5:48 pm

5:48 pm


Needless to say, the LTE radio in the Nexus is fantastic. I knew we had a strong network here but these speeds are crazy fast for that time of day!

[MarkyD]

I do have a Nexus. My Rezound gets similar speeds despite the Nexus displaying half the bars.
