Happy New Year 2014There’s so much going on in the industry now. Firstly we have the New Year. Happy New Year. I will continue my analysis from before, however things got interesting when the data showed something about specific vendor performance.

Last year LTE became mainstream for most technology reporters and we saw lots of drivel published. News wise, I think the key events from 2013 were : (1) the availability of LTE globally, (2) the start of roaming with AT&T’s announcement (with Rogers in Canada), (3) the Rockstar group Apple, BlackBerry, EMC, Ericsson, Microsoft, Sony- formed around Nortel’s LTE IPRs. (4) AT&T’s change of position on lower 700MHz spectrum (Specifically 3GPP Band 12) (5) Verizon’s  Carrier Aggregation (CA) and VoLTE trials.fig3_649x342 Most everything else was what I would call typical business activity.

CES2014

 There’s the CES show in Las Vegas, NV. going on now. So far there doesn’t seem to be a whole lot of innovation, save for some of Intel’s little toys like a tiny computer the size of a golf ball and a ‘bowl’ that supports wireless charging. Most announcements are for smaller, thinner devices with more pixels,  wearable fitness trackers. There is a cool FLIR camera jacket for an iPhone but that’s not really what I would consider as innovative.  

I will keep my eyes open and we will take a look at whatever interesting pops up. Stay tuned!

PrintRecently Verizon made some waves by announcing their intention to deploy LTE Release 10, specifically the Carrier Aggregation (CA) feature. Naturally I have lots to say on this topic so I thought I would forget what I wanted to say and just hypothesize and prove if true or not. So today is the hypothesis.

Verizon’s over the air (OTA) efficiency is very low with their existing 700MHz deployed channel, and this will not significantly improve without any changes. Therefore, my hypothesis is that when they flip the switch nationwide (depends on device/UE availability of course)  that only people living in deep fades will realize a significant gain… and furthermore, AT&T’s OTA speeds won’t seem that far behind with their 10MHz vs Verizon’s 20MHz. That’s pretty bold but I have my reasons. I will close today with a very typical observation… a clue, from Verizon’s network. Screenshot_2013-12-12-17-44-24 Thanks to my handy WINd tool- I can make these measurements 24×7 with no hands ma…:)

I’ll try to be wrong or right tomorrow!

 

the-secret-to-happiness Update: Serendipitously, Kevin Pritchard at GigOM just published an article on Verizon’s New network. I added some thinking about this below…

There’s disappointingly little to report from the Small Cell Forum meetings in Dallas, TX this week, was hoping for someone to make bold moves. Anyhow, ever notice that most LTE macro network operators are very hesitant to push the envelope as far as performance is concerned. It’s really surprising given that EVERYONE is deploying LTE, devices are more or less ubiquitous and so that really leaves performance and price as the key mobile data service differentiators. 

So that brings me to some recent press release I read about Root Metrics performance comparison of the US operators. Here is a sample of their data:

Average download and upload speeds by carrier 

AT&T: 17.0 Mbps download/7.6 Mbps upload
Verizon: 11.9 Mbps download/5.0 Mbps upload
T-Mobile: 10.9 Mbps download/4.9 Mbps upload
Sprint: 5.7 Mbps download/2.5 Mbps upload
Cricket: 0.6 Mbps download/0.4 Mbps upload

Let’s re-frame this data a little bit. Here is a comparison of Now to Then…

comparison_LTE_may12-June13

So what gives???

Verizon admits it can’t handle LTE demand in major cities (Nov-2013)

AT&T Is Deploying Intucell’s SON Technology as Part of Latest Wireless Network Upgrades (Feb-2012)

SON eh? There are other things they are doing but there are lots of things they are NOT doing either….

comparison_LTE_may12-June13_eff

To be fair, there’s a little uneven playing field here- Verizon has more extensive LTE coverage and more users, therefore you could argue the loading was not identical but on the other hand, with SON on your side, that’s is always true. 

Update!

As I mentioned above, Kevin Pritchard at GigaOM published an article titled “Verizon quietly unleashes its LTE monster, tripling 4G capacity in major cities”  BTW there is a similar article written 15 October 13 By Andrew Martonik in Android Central…Verizon deploying LTE on AWS spectrum in major markets

Here is the summary:

On the third anniversary of its LTE launch, Verizon is delivering a new 4G network. Over the last few months, it’s been quietly deploying the fastest, highest capacity LTE network in the country.

The GigaOM article touts the NEW Verizon network. Hmmm. So let’s look at this 2 ways. Firstly, for existing UEs, The current crop of RF baseband processors in devices like the Qualcomm 9615/Snapdragon 600/800 etc… support up to 3GPP Release 9, therefore most of the devices will only support 1 frequency at a time. I’ll explain why I said that in a bit. This means that old devices will remain on Verizon’s Band 13 (Upper 700MHz) AND only new devices (example: Nexus 5, Samsung S4 USA Version, iPhone 5S/c) will support their new AWS Band. So the capacity crunch won’t immediately feel much better. Next, the best that a user in each band can hope for from the network is 84Mbps peak or somewhere around 11-17Mbps per the tested results above. 

The reason I said 1 frequency at a time is that 3GPP Release 10 introduces a new feature called carrier aggregation. This allows the network and device to bundle multiple spectrums into a logical channel. In Verizon’s case this could be AWS and 700MHz channels sooner and PCS and 800 as time moves forward (and they refarm their existing spectrum.) So the good news is these users will see peaks closer to 150Mbps. I would call that the NEW Verizon network for sure. The bad news is the only device that currently supports that is a Korean market Samsung S4.

Qualcomm has added support for Carrier Aggregation in MDM9225 and MDM9625, so eagerly anticipate a faster Samsung S5 or Apple iPhone 6. So in summary, it’s a bit early to tout that Verizon has a NEW network. Back to my original point, until they get Carrier Aggregation, their spectrum efficiency of 1.19 vs AT&T’s of 1.7 won’t change much!

To the average consumer this means generally, slightly, slower throughput if a Verizon subscriber and Verizon is paying about a 30% premium over the air to provide the bits to you versus AT&T.

So it looks from afar that AT&T’s investment in SON is saving them at least 30% compared to their biggest competitor with identical spectrum. What’s holding everyone back from massive SON implementation again??

Lastly, the GigaOM article mentions that AT&T cannot do the same. Well, they could have if they converted their network to TDD, then they would have an even faster (peaks) network with 20MHz aggregated from existing then they could throw their MediaFlo spectrum (lower 700MHz unpaired block) at it. Instead they will go shopping. They tried to pick up TMO and use that AWS but it looks like the Band 12 guys just cashed in their golden tickets…

Stay thirsty my friends…most-interesting-man-in-the-world

VZW Rule The Air Logo Couldn’t help but notice that Verizon completed the transaction of selling off it’s Lower 700MHz spectrum today. Key point is, as long as it doesn’t go to AT&T consumers are better off. OK that had to be said.

The markets and spectrum from their PR is:

Nortex Communications, based in Muenster, Texas, acquired the Texas RSA 6-Jack 700 MHz lower B-block license, which covers a four-county area northwest of Dallas. Panhandle Telecommunication Systems, Inc., based in Guymon, Okla., acquired the Texas RSA 2-Hansford 700 MHz lower B-block license, which covers 12 counties in the northwest part of Texas. Colorado Valley Communications purchased a partitioned A-Block license covering a five-county area in the Houston market.

The next bottleneck, once the spectrum gets diffused into the market, is the availability of chipsets that support this spectrum, Band 12. See the diagram below for a quick refresher.

700MHz spectrum chart

I am planning to do an overview of this situation next so stay tuned. Yea for us. We got a little more market freedom today. Hopefully this will encourage some of the smaller operators to deploy LTE and compete with the big guys.

Fist Bump

 

 

BTW, When’s the last time we saw Munster, TX or Guymon, OK in a tech industry press release? Shout out to you peeps. 

 

 

 

Below is excerpted from their site.

Verizon Wireless Completes Spectrum Sales to Three Rural Companies

Verizon Wireless has completed three spectrum license sale transactions following agreements reached late last year as part of the open sale process for its 700 MHz A and B Block licenses. Nortex Communications and Panhandle Telecommunication Systems, Inc. closed on their respective purchases this week. Colorado Valley Communications completed its purchase on January 16, 2013.

Nortex Communications, based in Muenster, Texas, acquired the Texas RSA 6-Jack 700 MHz lower B-block license, which covers a four-county area northwest of Dallas. Panhandle Telecommunication Systems, Inc., based in Guymon, Okla., acquired the Texas RSA 2-Hansford 700 MHz lower B-block license, which covers 12 counties in the northwest part of Texas. purchased a partitioned A-Block license covering a five-county area in the Houston market.

Verizon Wireless offered its lower 700 MHz spectrum licenses for sale to rationalize its spectrum holdings and enable more spectrum to reach the marketplace where it can be used for the benefit of customers. As a result of the sale process, Verizon Wireless signed agreements with seven companies, including one national carrier, five rural or regional carriers and one minority-owned firm. To date, three purchases have been completed and four remain pending. Verizon Wireless is also getting 700 MHz C block spectrum into the hands of 20 rural operators through its LTE in Rural America leasing program.

public knowledgeOK there is a non profit named Public Knowledge, based in Washington D.C. of course, and fight for our networks to be open. I personally like that mission but they have put out a disturbing statement … See this:

AT&T is using the data caps that it imposes on its home broadband subscribers to disadvantage competitors to AT&T Wireless.

The AT&T 3G MicroCell acts as a miniature cell tower that can be used to supplement and improve cell phone service for voice calls or data applications. However,  AT&T is exempting data from AT&T Wireless MicroCells from the data caps it imposes on its wireless home broadband users. This is similar to Comcast’s decision last year to exempt its own online video service from its data cap.

The following can be attributed to Michael Weinberg, Vice President:

“AT&T is egregiously abusing data caps to give its own services advantages over competitors. There is no reason why AT&T should treat AT&T Wireless MicroCell data different than any other data – including data from a Verizon or Sprint MicroCell – on a subscriber’s home connection.

“Internet service providers should not be able to use data caps anti-competitively. When providers give preferential treatment to data associated with their services, they undermine competition and inhibit innovation. This is precisely the type of discrimination at the core of the net neutrality debate. The FCC and, if necessary, Congress must take steps to end data cap abuse.

AT&T microcell small cell

OK this is a bit misguided. The AT&T Microcell  allows AT&T subscribers to avoid data caps by NOT carrying user traffic over the WCDMA/LTE macro mobile network infrastructure, but pushes it upstream on the END USER’S BROADBAND connection.

C’MON, what’s the problem with that???? Am I missing something here? It’s not like the neighbors can’t buy a MicroCell from their neighborhood AT&T store to avoid going over THEIR data cap, or just connect their own home broadband to a WiFi AP to bypass the AT&T network… Heck, as of today Facebook lets you call each other so this is not even relevant to voice.

The only way I can think to make sense of their complaint is if they are complaining that the small cell core infrastructure (ignore that it’s just SIP based, for now) is closed, thus limiting what types of small cells we end users may obtain and use on the network. There could be an interesting ecosystem here. I doubt this is their angle but it’s a valid complaint.

jackie-chan-wtf-face-i16_m

So an asymmetrical attack, Sprint and Verizon have deployed far more small cells, without technical merit really 99.99% of the time comes from your competitor.

Anyway things like this irritate me to no end…

 

Welcome to Las Vegas CES Been awfully busy this year and end of last so I’m wayyy off my desired schedule. The Consumer Electronics Show (CES) is quite the boondoggle and this year was no exception. There were a couple of things that were noteworthy to me with respect to the mobile industry and 4G that I would like to share with you.

Firstly, Qualcomm’s keynote. Usually Microsoft handles such things but this year Microsoft minimized their CES profile by not having a big booth etc… This is not really surprising to me as it was to some as they are exactly duplicating any/everything Apple does w.r.t. mobile.  Anyway Qualcomm tried the shock and awe approach to keynotes and added a bunch of colorful characters into the talk like Desmond Tutu, Big Bird, Steve Balmer, Guillermo Del Toro, Star Trek’s Alice Eve etc… Bottom line is they are going to continue to work hard to be the epicenter of wireless.

They unveiled their Snapdragon 800 mobile processor which supports everything including Ultra HD and it’s expected we will see that in next versions of mobile devices. Qualcomm also discussed their wireless charging (Inductive Power Transfer) technology a little, the brand they are selling is Halo and they are focused on getting it into vehicles initially. Wireless charging is the next logical step for all electronic devices so this makes a lot of sense. I will also mention they mentioned, with Big Bird’s help, their version of augmented reality. This is another technology I expect to be ubiquitous this year.

Cracks me up that after years of trying to talk them into small cells, they are suddenly the center of the small cell universe too. Better late than never. Ok I digress…Video of Qualcomm’s keynote highlights to your left. 

Following the keynote there were the strictly routine level of show floor booths, demo days, meetings in conference booths on/off the show floor, night out etc… This is a CES so the main focus is mainly non-mobile, and there was a lot of buzz around the forthcoming UltraHD (4K) TV’s and the always heralded but never sold in stores OLED versions of TVs. OK, 4K/OLED is cool and the only tie to mobile is you can expect these technologies on the 4th screen (mobile device.) 

Almost forgot, Samsung demoed their “Youm” bendable display. It doesn’t have anything to do with 4G but you could see one on a Samsung G4 or Galaxy 5.

 

There was an interesting group of demos around wireless power charging. Yes what’s old is what’s new. There are many companies in the developing ecosystem and I won’t really go into each one but they are aligning into alliances or industry trade groups.This is the same technology battle that happens when standards compete, so Rocky-Balboa-movie-20for example, with Betamax v VHS, Firewire v USB, CDMA v GSM or LTE v WiMAX, there will be winners and losers and the loser may have the superior technology, or not. So one approach was QI by the Wireless Power Consortium Wireless Power Consortiumrepresenting 100 companies, and by 130 announced products so far. They claim all QI certified devices are going to be interoperable (wireless charging wise.) Their technology is wireless but immobile, based on induction through charging pads etc…

 The second is the 25ish member Alliance for Wireless Power. A4WP Logo The big differentiator here is they allow more flexibility in how close/far the charging devices may be placed up to 50mm from the charger. (wireless, not quite mobile) What this group lacks in numbers they make up for in strength of their supporters.

Lastly, the third major exhibitor was the 30ish member strong Power Matters Alliance.Power Matters Alliance The technology differentiation is less clear to me, a wireless charging surface based approach but I guess their focus here is integration into public places. Yes, Starbucks is a member. 

Oh yeah, the waterproofing guys were back with a better process. I love little things like Liquipel! They offer a waterproofing coating for your mobile device that allows full submersion for a limited amount of time, like when your phone falls out of your front shirt pocket into a water fountain etc… (feel free to substitute your experience here.) Liquipel waterproof iphone

 

So all in all, the state of the art is inching forward. No major LTE Advanced announcements. 

Verizon @ CES

Oh wait, Verizon announced they are planning on launching an Evolved Multimedia Broadcast Multicast (eMBMS) service in the future. This was from the CEO Lowell McAdam. There were no specifics like timelines or what type of content but overall it makes sense to utilize their investment as much and as wisely as possible. 

Verizon has a site dedicated to eMBMS and they state they are working with Ericsson. 

Verizon Keynote here… 

OK, looking forward to this stuff now…

Ahead of the signaling show (who knew?) that starts tomorrow … I have been noticing a flood of information including various press releases about LTE roaming. I don’t have much that I can say publicly other than what I can observe in the public domain. So I wanted to point out some recent examples.

As you may or may not know, there’s some real challenges to LTE roaming around the radio interface, such as the ability of a device to operate everywhere based on radio bands supported, other than that, nearly all other big issues are primarily in the business domain if you exclude VoLTE for the moment.  I thought it would be interesting to have a look at some of the public info out there regarding LTE roaming.

Firstly, why LTE roaming? Simple, there are LTE subs nearly everywhere now. Chart above shows something like 100M now. Unlike 3G with the different flavors, this is interesting because multiple (or greater number of) networks could potentially host foreign subs in a given location and since the subs are substantially on a single standard, a greater number to deal with.

As you can probably guess, there are 3 domains the situation exists in. Firstly is from the network standards point of view. 3GPP and others have been working on filling in the gaps to help the situation. Release 9 and 10 fix some roaming holes in the standard (actually just standardized the fixes) and go a long way. Beow Sybase has a network diagram for your viewing pleasure. You may recognize that Diameter is a key protocol between the networks and it’s relatively new into the marketplace. Verizon and others are still discovering the ins and outs of using it. 

Next up is the obligatory network diagram that shows at a glance the network topology of the roaming signaling situation.

The second domain is the network OEM perspective. There are several players in this space like Sybase, Diametriq, and Syniverse to name a few. They offer products to assist with the roaming infrastructure and or provide hosting services to enable it. 

For example, here is an interesting slide deck describing a Diameter Signaling Controller from Diametriq. Notice the comments about operator challenges and the complexity just within the diameter protocol universe.


And Syniverse announces hosted Diameter services…

Syniverse Solutions Ready SmarTone for LTE Interoperability 

Here is Syniverse’s deck that’s fairly interesting titled, Preparing for LTE Roaming

Outside of that there is 3G roaming that already has lots of glue in place. It gets complicated when considering that LTE networks can communicate much easier over the wire to each other, however using a completely different protocol set and network topology than what is in place, yet the 3G fallback is highly desirable (Voice or edge data coverage.

Some service providers like Global Telecom have taken the initiative to be a first mover in this area. 

Globe beats rival telcos with LTE roaming function

Ultimately having some service providers go first will help to accelerate the LTE roaming marketplace in general.

The final domain of LTE roaming challenge belongs to the UE. The recently launched iPhone5 and iPads do have LTE, which will increase demand based on their historical popularity, however these devices are based on Qualcomm RTR8600 technology limitations that do not facilitate a single chipset for all bands, therefore there are different models that can use different sets of spectrum. Sysbase’s William Dudley recently posted about the iPhone5 and roaming in:

iPhone 5: A Catalyst for LTE Roaming?

Smith Micro Software is offering something in this space, a mobile based solution that focuses the smartphone on using WiFi to offload and presumably avoid roaming over LTE.

To me, until there is a simple solution that allows a single device to utilize all LTE bands being deployed this is the biggest hurdle for LTE roaming to become widespread. However, when it finally does happen, the commercial possibilities are exciting as the increased competition will improve choice and pricing globally thus fueling more adoption perhaps in the Machine to Machine (M2M) space where we will be able to have all of our cars, homes and non phone type gadgets LTE enabled.
Just an observation.

So I’m trolling the internet during a conference call and whoa, what’s this? An article in CNET about LTE speeds. Seems like everyone is interested in LTE all of a sudden. Anyway here’s the page:

 Don’t get me wrong, I laugh at Verizon and AT&T’s LTE implementations but this article makes me want to cry. The REAL reason the speeds in NYC are averaging in the 20MBps range and Sydney is like 40MBps is…

 

Verizon and ATT have 1/2 the bandwidth deployed that Optus (Australia) does! (FCC Hear that?) The US operators’ Verizon (Band 13) and ATT (Band 17) have deployed 10MHz channels in lower 700MHz with 2×2 MIMO whereas Optus (Band 3) has a 20MHz channel with 2×2 MIMO. Double the resource, double the rate.

 

There are 2 LTE stories here, with 1 bow tied neatly around. See this…

 So I was reading about the Dish Networks deal with Qualcomm that starts with Dish has 40MHz of S band (~2GHz) that it wants to use for LTE. Then I read that they did the smart thing and signed a deal with Qualcomm because let’s face it, Dish’s ambitions are not going to get much traction without devices. That all makes sense to me and although I can’t say I think getting this to market by 2016 will make them the dominant LTE service provider for the ages. IntoMobile has a good story on this.

Next, I read that Verizon is forming The 4G Venture Forum for Connected Cars with partners like BMW, Honda, Hyundai Motor Company, Kia Motors and Toyota Motor Sales, Inc. Looks like the goal is to foster ecosystem to grow infotainment and telematics over Verizon’s LTE network. Again, this makes a lot of sense to me and without going into tremendous detail, I will say I think this is where the Verizon’s of the world will make the real money from LTE, not from you and I directly, but as channel partners to the connected world. So they will need to work on safety issues, standards blah, a good step.

So hmmm… Why doesn’t Dish use it’s Lower 700MHz E block spectrum to operate a TDD-LTE, Multimedia Broadcast Multicast Service? More specifically Multimedia Broadcast Multicast Single Frequency Network (MBMSFN) and MBMS What is this MBMSFN you ask?

Good Article: eMBMS for More Efficient Use of Spectrum

Good Overview Document: Broadcast and Multicast Service for LTE and Advanced

The Multimedia Broadcast Multicast Service shares resource blocks so that a single unit of data is conservatively shared between multiple UEs therefore not committing separate resources for each UE. Further, the MSMSFN mode of operation simulcasts the same data, synchronously over multiple cells, and since over the air combining is possible, the  Signal to Noise Ratio (SINR) is improved a great deal. This is ideal for broadcasting media. Think in car movies for example. This would be cost effective and easy to achieve. What about Pandora audio or even digital signage ads (read the UICC from the UE and now we have a Minority Report style service)?

There is nothing that is unachievable with present technology, if you consider Dish is already reaching out to add the S band to chipsets and TDD is already being realized in the market. Dish already has a user experience expectation and backseat car infotainment is not something they are not trying to serve already. Seems like a slam dunk to me.

Verizon Joins With Leading Global Auto Companies To Establish 4G Venture Forum for Connected Cars

BASKING RIDGE, N.J., June 6, 2012 /PRNewswire/ — Verizon today announced the formation of the 4G Venture Forum for Connected Cars, a group of leading global automotive companies brought together by Verizon to accelerate the pace of innovation across the automotive and telematics 4G LTE ecosystem.

BMW, Honda, Hyundai Motor Company, Kia Motors and Toyota Motor Sales, Inc. are joining Verizon as the initial members of the Forum.  Professor Sanjay Sarma of the Massachusetts Institute of Technology also joins the Forum, providing members a link to track important advancements in related academic research.  The group will collaborate and explore ways to deliver connectivity to vehicles of all types, by leveraging open standards and discussing ways to accelerate development of the 4G LTE ecosystem across automotive OEMs, suppliers, device manufacturers, application developers and content publishers.

“There are many challenges to designing next generation telematics and infotainment solutions, including supporting safe and responsible driving, advancing vehicle-to-vehicle solutions and improving sustainability, among others,” said Tami Erwin, chief marketing officer for Verizon Wireless.  “As an innovator in the technology industry, Verizon is a natural impetus for this collaboration, which we all expect will include other companies and spur results that will benefit not only the industry, but millions of consumers around the world.”

Telematics is a growing opportunity that integrates telecommunications and information into vehicles to provide functionality to drivers and passengers.  The 4G Venture Forum for Connected Cars will help discover ways to increase the value of services, ranging from embedded cloud-connected solutions to mobile applications; help define features and explore safety systems; and encourage third-party developers in this space.

Verizon has a strong commitment to collaboration and innovation through its Innovation Program, and through the 4G Venture Forum, which was created in 2009 to identify and support new ideas related to advanced wireless networks and to provide market validation for innovative companies.  The 4G Venture Forum for Connected Cars complements and extends the approach of the 4G Venture Forum, focusing exclusively on the automotive space to address the specific needs of this growing market.

Verizon Wireless has the largest 4G LTE network, now available in 258 markets and covering more than two-thirds of the U.S. population.  The Forum may support and fund advancements regardless of underlying network technology; companies will not be obligated to work with Verizon and are not precluded from working with other service providers.

 RootMetrics has been publishing network performance results. The latest one shows the discrepancies in LTE/WiMax/EVDO in the Las Vegas Market. It’s an interesting read but take this all with a large grain of salt as I have noticed that there are lots of reasons for the performance skews for ATT, MetroPCS, Sprint and VZW. Not saying their data is invalid but I do know of lots of issues behind their numbers that I’m probably not at liberty to discuss so draw your own conclusions… Full Las Vegas Report is here…

 All of their reports are here.

From the Las Vega$ report:

We’re back for more!

This report marks our second visit to the Las Vegas market, having also tested the area in November of 2011. We found some notable changes that might impact your mobile service decisions.

  • By far, the most significant change was AT&T’s LTE network upgrade and the dramatic impact it had on their data speeds: AT&T’s average download speed increased from 3.3 Mbps to 16.2 Mbps, while their average upload speed increased from 1.2 Mbps to 5.4 Mbps.
  • Though not nearly as dramatic as AT&T’s improvement, T-Mobile and Verizon each recorded faster average download speeds this visit compared to what we found in November.
  •  The speeds recorded by Cricket and Sprint showed small variation from what we found during our previous visit. MetroPCS was slower this time than what we found during our previous visit.
