And Dalvik takes up system resources, right? Like memory and CPU time.

So why wouldn't Google go with the most efficient architecture? It's not a PC where you can throw in 8GB RAM for $50.

Which architecture would that be that can run as many hardware variants as there are on Android phones?  There's not one Android phone like there is one iPhone, and if you look at the Windows phones there's not much variety here.

Instead Java classes are compiled into Dalvik executables and run on Dalvik, a specialized virtual machine (VM) designed specifically for Android

It's not just Java syntax but the use of a virtual machine that it calls Dalvik which is the same concept as the Java virtual machine.

 

Here's a nice history

Yes Android uses Dalvik, NOT Java.  Ask Oracle if Dalvik is Java.

You brought up one app as an example, but do you really think Android is not capable of running the Speedtest app like the IOS version?  Or is it more plausible that not as much development went into the Android version?  The graphics are slightly different as well; do you think that's Dalvik's fault?

Other apps such as the browser and 3d games are much more demanding on system resources than the Speedtest app, and those usually run quite well.  The iPhone for the most part has the best gpu on the market, so that helps with 3d games, but 3d games that are optimized for high end Android phones also run quite well even with Dalvik.

Google doesn't use Java in Android.  It just uses the Java syntax to tap into the developer base that already knows Java.  I'm sure Android could do the Speedtest app like the iPhone if the developers wanted to.

The extra ram helps because Android's multitasking is more extensive than the other 2 platforms.

Here you go, guys, the FCC Report and Order for the PCS/AWS-2 H block rules. 126 pages. You have your weekend reading. The quiz will be first thing on Monday.

For the people much more knowledgeable than me, would sprint be able to run 10x10mhz channels with the G and H block combined? Or will the power transmission limits prevent that?

Dish will most certainly ask the judge to dismiss the case based on the withdrawal of its offer. It will be up to the judge to dismiss it only if he is comfortable with dismissing all of sprints claims

But the damage was already done

 

Aj,

I haven't been around these forums much lately, however, I do drop by from time to time. I was directed to this topic via a link on the android Central Forums from a member there . So even if the post 3 months old or not I don't See it as a problem?I just read and replied. upon your sarcasm as you put it.

 

Robert,

My reply was based on

What happens when the lte here

Drops out.

Maybe it's not the same as how it is in New Mexico?

But that's how Tmobile has it setup here.

And if it's just an overlay?

Why do I still get hspa when lte drops out? Wouldn't they both drop out and put me back on edge? If it was just an overlay?

 

Ever since lte went live here about a month ago? I don't seen 2g edge anymore. Currently It is only 4G lte or 4G. Signals and speed are pretty good where ever I have been so far. Even 2 stories underground at work where our company nextel never did aquire a signal nor my evo with Sprint.

Just to let you know... Sprint in Hawaii is still very, very, very slow.

Hope that all changes when softbank takes over though.

The real issue is currently, where TMobile has HSPA+ and it drops to Edge, the other carriers are still on their respective 4g or 3g networks.

One thing I don't like about Windows Phone are some of the exclusive apps that are manufacturer specific.  There is an ESPN Hub and ESPN fantasy football that is only available on Nokia Windows phones.  Exclusive apps to differentiate I understand, but exclusive third party apps doesn't make sense to me.  Windows Phone needs as many apps as they can get to get more people to buy into the operating system.

Sprint's lawsuit against Dish is still on though, correct?  Can Sprint get damages because they had to up their offer vs Dish's allegedly illegal offer?

It sounds like Dish is going to cause more trouble getting Sprint/Softbank into a bidding war with the H block.  How much time does Dish have left in their build out requirements for the AWS spectrum they currently own?  And when do we expect the auctions for the H block?

Kind of random to this topic but how are you liking AIO? I've been really interested in them. Wondering how AT&T's coverage is, in general and indoors, and what kind of speeds you're seeing. Also curious if you've hit your data limit and if so what speeds you get when you're throttled. They don't specify on the site.

From my post in the Tmobile LTE vs Sprint LTE thread:

http://www.flickr.com/photos/97640493@N02/

 

I'm at work and don't have an imgur account, but that's a screenshot from Flickr.  I'm using a Nokia 920 so this speedtest app is from Windows Phone 8.  The screenshot doesn't show ping times, but they were typically in the 250 -270 ms range, which is slow for LTE.  It probably goes through a proxy server so AIO can keep track of data usage.

 

We're starting to get off topic though, so it's probably better to create another thread if you want to discuss AIO or AT&T Go Phone LTE service.

I'm happy with the service, but with the high ping times on AIO it feels like Sprint's LTE is snappier when you have a solid LTE signal.  AIO speeds are always good enough though, AT&T's LTE is more extensive and in weak signal areas where Sprint would fall back to 3g, with AIO I'm still on at least HSPA+.  I haven't hit the data limit yet, but I spoke to tech support when they launched LTE, and they said once you pass your data limit you're throttled to 256 kb/s.

The rate plans on AIO's website are just for the Florida market though.  In Houston, the choices are $50 for 1gb and $65 for 5gb (both with unlimited minutes and text).  There is a $25 activation fee however. Overall I'm very pleased with the service and don't plan to ever sign a contract again with all the mvno choices out there.  I'm on the $65 plan, and that includes taxes so you don't pay anything on top of the $65.  I bought the Nokia 920 off of craigslist for $300 to try out Windows phone and AIO and so far so good.

I work just south of the galleria near Bellaire and 610, and for the last couple of weeks I noticed my phone would periodically switch to 3g. I normally stayed on LTE prior to this, so I'm not sure what's going on. My contract recently ended though and I switched to AIO wireless (AT&T prepaid with LTE)

Can you post screenshot of speedtest?

Since ATT just announced AIO has LTE, Tmobile has a problem.

 

The only value it adds now compared to AIO is its 0% financing.

I just signed up fo AIO last week here in Houston before LTE was announced, and then 2 days ago my phone started showing LTE.  Speeds are capped at 8 mb/s according to the website (which is more than fast enough), but since it goes through a proxy server ping times are on the high side for LTE, usually over 250 ms.

It's not the true AT&T LTE experience (my friends here in Houston regularly see 30+ mb/s and ping times in the 40-60 ms range), but for a month to month service I'm more than satisfied.

This phone actually looks very nice for a mid range phone.  Specs look comparable to the Galaxy S3.

Wow - Just looked at the coverage maps for Miami - and it shows LTE coverage all over...  This is def not right.

That's how Houston was back in July/August of last year. Coverage map showed blanket coverage but that certainly wasn't the case.  Now Houston is about 70% (according to the Network Deployment List) complete and I'm on LTE about 95% of the time.

_{I would rather use an MVNO or prepaid once my contract is up.  AT&T is launching new Go Phone plans starting 6/21 with unlimited talk and text with 2gb of data, so that's enough for me because I've been averaging 1-1.5gb with Sprint the last few years.  For heavy data users it would still make sense to stick with Sprint or TMobile since they offer unlimited data.}

With all the talk about Clearwire holding somewhere between 100-160 mhz of spectrum, does Sprint really need that?  I would think if they get 40mhz and use that in high traffic areas it would be enough bandwidth for the foreseeable future, and let Dish/Clearwire do whatever they want with the rest.  Or up that amount to 60 or 80 mhz for additional headroom in the future, but you'll still leave Dish/Clearwire some spectrum for their own purpose.

That was my point regarding uneven experience: it's a huge drop in speeds from 2.5GHz to 800MHz.

Sprint will have 5x5 channels in most places with 800 SMR LTE, so speeds should be similar to the current 5x5 LTE they're deploying.  Does it really matter on your phone if speeds drop from 20-30 mb/s to 6-8 mb/s?  It's not like Tmobile where you can be on 4g (either their LTE or HSPA) and switch to edge.

That's all good but what about building penetration? I've never had a WiMax phone but all forums are filled with complaints about signal strength.

 

My point was that 2.5GHz will only be useful outside.

That's where the 800 SMR band LTE comes into play.

Yes, but, Sprint's towers are at PCS spacing, right?

So even if Sprint eventually puts 2.5GHz on all its 38k+ towers, it's gonna be an uneven experience.

You don't need to be on Clear's frequency to get a better network experience.  Everyone else who is on Clear's frequency means that they're not on the Sprint tower you're connected to and overloading the tower.

I used to think I needed unlimited data, but looking at my usage for the past 2 years I'm usually at 1-1.5gb of data.  I guess if you're always streaming Netflix or Spotify is when you really need unlimited, but you'll also need to keep your phone near a charger too.

I really wouldn't mind trying Cricket when my contract is up with Sprint.  I'm in Houston and they have LTE here, and their rate plans are pretty cheap. 

Sorry, but this is not an Apples to Apples comparison because $70 on TMO includes unlimited talk. The same publicly available plan on Sprint costs $110 which is significantly more! 900 minutes is $100, also more.

Sprint has unlimited mobile to any mobile, so for 95% of the population it is essentially unlimited minutes at the lowest rate plan. I don't think I've used more than 20 any time minutes in any given month the last few years.

Ooh, a new built-for-Android IDE. Just might pick that up (hi, my name is Ian and I'm a software dev).

 

Might switch from Rhapsody to Google Play Music All Access as well, but the price of the two services is the same so I'm not sure on that one. Have to look at selection.

 

I'm currently using Rdio, but I'll give the new Google Play Music All Access a shot since there's a 30 day free trial. Also, it was mentioned that if you sign up before June 30 that it'll be $8/month instead of $10 like Rdio and Spotify.

I mean from a business perspective, just because LTE will be everywhere doesn't mean legacy networks wont be in service (plus since you have to have it running you may as well sell as much services on it as you can to maximize the capital you invested in it), I am saying the business case every 6 months makes less sense in CDMA networks, when you know it will come to an end. I am not talking just smartphone users but M2M, and the "internet of things" and utility requirements. The carriers make a lot of money and will make even more to come.

From a business perspective it doesn't make sense either. Instead of putting money into the LTE network, they would have to divert some of that to UMTS, and put UMTS on spectrum that they don't have, or take spectrum away from 1x and have customers complain about degraded service because the network is overloaded.
