You can tell M2M is coming of age at Axeda's Connexion13 The Music blaring in synch with the video splashing. The feel good sense that you are part of something bigger. Axeda is making the point that this is about the Machine Cloud.

Todd DeSisto, President, Axeda Corporation. Four days of case studies focused on Remote Services, Business Process, Process Efficiency and Optimization.

Bill Zujewski (a.k.a. Bill Z.) now speaks about the Machine of the future. The Evolution of the future.

1970 self contained hardware very little software
Next 1980s Software enhanced digital interfaces
Next 1990s Modem connected communication with firewalls
Next 2010s Programmable Machines

Machines of the future (2020) are;

Connected via the cloud managing the connectivity whether wirelines or wireless.
Serviceable being able to reconfigure manage and reducing field service with remote management
Trackable keeping the location information for the benefit of security, efficiency and optimization.
Informative delivering more information (big data) that provides opportunity to expand the original implementation for more benefits.
Self-Healing making the machine 2 machine sensors better integrated in the machines to reduce the risk of downtime with predictive analytics.
Integrated with ERP, CRM and other systems for proactive management decisions.
App-Centric the hardware is not as relevant as the software so cross platform association to consoles but to specific applications will be the norm.
Eco-Friendly data extraction so the energy use of the M2M applications is optimized for the costs and cleanliness of the solutions.
Collaboration the deployments deliver new apps and new benefits.

Expanding The Value Curve
Level 7 socialized sharing Machine information
Level 8 Multi-vendor enabling metrics across the vendors to deliver better ecosystem information
Level 9 Cross - Industry supporting more information to be used by more opportunities (Personal Note: I think the Eco-Friendly is the best example)

Where is IT in this for business. Just like BYOD efforts we are heading to BYOM (M is for Machines) and the result is IT is going to have to use the platforms as a Mobile Machine Management tool.

The Power at the Edge

2011-10-28T22:09:47Z

People are expecting that the way they communicate in their everyday life is all part of the services they buy with their phone. The regulatory concepts of access and content mean little to end user. They expect that everything works, and they have not noticed that everything does not work together. The Real time communications event did a nice job of exploring that opportunity.

SIP is being pushed into the Web with RTCWeb and the rich media opportunities that provides. Texting and videos to 911 are assumed even though no process is in place to accept them.

I should also mention that the kids at the lab have done a lot thanks to corporations using the lab as a resource. Carol Davids is looking to support corporations with lab work performed by IIT students. If you want to see what a millennial will do with your product, you might want to put it in their hands at IIT.

Open Letter to Congress (and Anyone Else)

2011-01-27T20:17:26Z

Dear Senator/Congressman

As you are aware the role of the FCC and the goal of providing a National Broadband Policy is very much in question and requires you guidance. We believe the old models need to be rethought and we have addressed the discussion in something we call Regulatory 2.0. http://4g-wirelessevolution.tmcnet.com/conference/east-11/regu.aspx

We are holding a conference that is available to you and your staff just by registering at http://www.4gwe.mobi. Please join us on February 4^th from 9 AM EST to 1PM EST. If you would like a formal briefing on what was said we can arrange that as well.

Kind Regards,

Carl Ford

Ceragon got MCel's Backhaul

2010-11-04T19:27:26Z

In a few weeks, I am running a webinar with Ceragon.

I received a press release from our friends at Ceragon, that mentioned the following...Ceragon Networks Signs Multi-Million Dollar Contract with mcel. Largest Mobile Operator in Mozambique to Install 1000 km Microwave Backbone Network

PARAMUS, N.J., Nov. 3, 2010 /PRNewswire-FirstCall/ -- Ceragon Networks (Nasdaq: CRNT), the provider of high-capacity, 4G/LTE-ready wireless backhaul networks, announced a multi-million dollar contract with Mobile Cellular (mcel), the largest mobile telephone operator in Mozambique, reaching all 128 districts of the country. …

You can read the rest of it here.

I asked a few questions and here are the answers from Ceragon.

Question 1) Is this a greenfield for the deployment or are you being added to existing towers?

Answer. Most of the network is upgrading existing infrastructure, some is Greenfield. BTW – our radios enable mcel to use less equipment (and towers) because of better system gain (stonger signal, loger distances etc.)

Question 2) Is there psuedowire involved from Ceragon and if so how do you address timing?

Answer. No pseudowire. Currently the network is geared for TDM only. Upgrade to IP can be done via hybrid approach – hence no need for PWE

Question 3. What demand expectations are there for the 4G/LTE user base? Is this a consumer prepaid market? What are the drivers for the deployment?

Answer. Currently main mobile app is voice. However, this wireless backbone will also deliver traffic from and to the underwater cable that reaches Maputo enabling broadband at large.

Question 4. How long will the roll out take place and when will LTE be delivered?

Answer. The network should be operational early next year (2011). I don’t know what mcel’s next-gen network plans are

Question 5). Will mcel be totally fiber free in its backhaul, or will it be part of the plan to migrate away from Fiber? Do they have issues with weather and other problems that make fiber a poor choice or is strictly a cost model?

Answer mcel has some fiber plants, but they will not dig 1000km of fiber any time soon. There are no major climatic issues

"Delivering reliable mobile service to our customers is extremely important to mcel," said Mr. Arlindo Mondlane, mcel CTO. "We selected Ceragon's products because they are technologically superior, use spectrum efficiently, and are highly reliable. Through careful network planning, we will be able to provide high-quality mobile service to our customers as cost-efficiently and as quickly as possible.

"Ceragon's microwave systems are practical and economical alternatives to fiber optic lines and are highly reliable point-to-point backbone transmission systems," said Ira Palti, President and CEO of Ceragon. "Our solutions are ideal for fast-growing mobile networks such as mcel's, scaling to meet future needs, and offering high reliability to customers in developing countries."

Over the Top - Money

2010-09-30T15:53:50Z

Who cares if you carriers billing system is working right? when you have all these options to pay from the web. Once again the mobile Internet is really just the Internet.

Watching a panel of companies at Gigaom's Mobilize of companies successful in mobile payments. But it is all over the top.

The companies include Boku, Groupe Hi-Media, Mastercard, Paypal, Zong

Interesting Geoff of Mastercard, has not brought up Smart Cards.

Missing the Point on e911

2010-09-23T16:06:52Z

The Commission is rearranging the deck chairs on e911.

First of all to their credit they want to improve accuracy of wireless services. According the Chairman Genachowski over 50% of the e911 calls need better details.

Then came examples of suggestions for people to tell the dispatcher. What Floor you are on, what are nearby landmarks. All good stuff except they have little to do with the GPS system.

On the other hand, pictures using MMS, or email would be useful.

Oh Wait! The dispatcher does not have capabilities for these things.

It would be nice if more emphasis was placed on fixing the government's side of the connection and upgrading it rather than putting pressure on the private sector to deliver more details.

Worse, solutions such as VoIP they force fit the old rules upon. It makes me wonder if the commission had been around at the beginning of POTS would it have required an integration to the telegraph. After all at the time it was the central point for all communication.

The sad reality is that we could build a better 911 application on Android than any dispatcher can get from the current system. Anyone up for the challenge?

4G is in the Stars: Satelite to Terresterial

2010-06-11T13:14:29Z

As LTE networks begin the testing phase, one mobile phone competitor, SkyTerra Communication, is planning to build a nationwide wholesale mobile network using a combination of Mobile Satellite Service (MSS) and an ATC (ancillary terrestrial component) network to deliver 4G mobile capability.

I plan to bring in three industry visionaries to discuss this bold and very interesting strategy. The discussion, in the form of an audiocast, will take place on June 15^th at 11:00 a.m. and you can register here. The audio cast will be a panel discussion, moderated by myself and three very astute industry visionaries see their bios below.

The mobile satellite business plan is the Holy Grail for those with the vision that satellites can provide "universal" 4G mobile service to the typical consumer. The MSS strategy has been unsuccessfully attempted in the past. But now, better chips, better phones, and bigger satellite dishes are pushing more power than ever to smaller handsets - making the business case for MSS more likely.

The satellite plan is of great interest in both urban and rural areas as the network could deliver the ubiquitous and redundant mobile service for public safety and first responders. The SkyTerra business model became newsworthy when on March 26, 2010, the FCC issued an order approving the merger of SkyTerra Communications and Harbinger Capital Partners. The Commission included controversial requirements and conditions that would potentially limit the use of Verizon Wireless and AT&T wireless networks by SkyTerra.

Aside from the contentious issues imposed in the merger order, there are other matters which are of interest for industry vendors, regulators and mobile users. The SkyTerra business plan, filed shortly after the March 2010 merger order, would give public safety much of what was sought in the D-Block 700Mhz auction - that is a provider of a single, nationwide, redundant mobile network using a low cost handset. SkyTerra is potentially in a much better position than FrontLine Wireless was to build out a nationwide network that would allow public safety to communicate from across departments. The loss of cell towers would not limit public safety from communicating. Also, the ability to deliver broadband mobile capacity to rural areas would provide an alternative to expensive special access.

Some issues that we will discuss on this call include:

1. Will the SkyTerra project change the FCC's position on the 700Mhz D-Block?

2. What is the FCC's current D-Block plan?

3. Has the Commission initiated a policy of supporting more wireless competition by limiting the largest providers from participating in future spectrum auctions?

4. Will the Commission conduct such thorough competitive reviews with stringent conditions of future mobile mergers as it did with SkyTerra and Harbinger?

5. Could such future Commission orders increase mobile competition in the U.S. but further erode slowing user growth and ARPU for the largest mobile providers?

6. Is 4G mobile satellite a reality or just a long shot?

Just in Time For Mobile World Congress

2010-02-09T18:02:11Z

Supercomm was cancelled for 2010. While it would interesting to talk about this from the conference side, I will make the assumption that other people will take that opportunity and try to talk about it from a different perspective.

CES was hoping and the buzz was around various forms of wireless use. Ford with Sync, Microsoft with KIA, Wireless devices and devices using wireless were all around most of them Internet enabled.

Mobile World Congress is going on in Barcelona and it's expected to do well next week.

I want to point out that these events are following the money which is no longer about the network its about the consumers freedom of choice.

As congress and the FCC contend with the legacy of the PSTN the new network is flourishing and its not about wireless its about customer choice. The wireless world may still have the same issues facing it that their fixed line brothers faced. Brough Turner points out that over 90% of the packets on any network head for the Internet.

If I were at the FCC I would be ready to advocate that its time to treat all networks as if they were accessing the Internet. Looking at competition not based on the technology but on the services and the primary services. Voice, video and data are probably going to converge at some point as well with the over the top (internet) model

Legacy service providers are looking for protection, but government should praise itself for enabling the competitive landscape we are heading for rather than embedding old rules into the new environment.

In these days of government bail outs its hard to see what is the economic downturn versus technological progress.

If the goal of net neutrality is to support the progress, I would contend it's to dynamic a market to codify. If its to protect the applications from abuses by the legacy networks, I am not sure its needed.

LG Breaks the Categories, but not the model

2010-01-11T16:14:57Z

"It's not a Femtocell!"

Chris Zeigler at engadget took this picture and as asked what is this thing?

If you live alone and you don't have to keep the family entertained. Why have the Internet Access at the house and not with you. That seems to be the reasoning behind the this terminal adapter. That connects your LTE phone to the house and gives you connectivity.

Given the fact that 60% of CES, was trying to move video from the Internet to the media server in the house, this would probably require some network smarts.

In my humble opinion this places LG's LTE closer to the dual mode camp, but since they have femtocell strategies, it maybe this was an internal product that had to be different the LG / Nortel Femtocell.

Can we call it MonoMode?

Google vs. Apple

2010-01-05T19:58:13Z

Google and Apple are vying for your attention today.

If you are a carrier, your bed fellows are not staying the night! Google with the Nexus One announcement that is all about the Android operating system and not a carrier. And strangely enough the Apple iTablet maybe the same thing. The rumors on the iTablet seem to indicate it may be devoid of 3G / 4G wireless interfaces and only support WiFi. While that will be a major plus for ATT who has already worked with Apple on the dual mode functionality of the iPhone, I should point out that Verizon has been the better company at supporting the use of USB 'sticks' (dongels?). It will be interesting to see if a bundle comes from either of the two carriers with the iTablet.

I am STUNed with the Jonathan Rosenberg / Skype announcement.

2009-11-09T20:30:21Z

The appointment of Jonathan Rosenberg as Chief Strategy Officer adds a new wrinkle to a career that started in "The Labs" and now moves beyond Cisco. He has followed voice to app side all his career, and now he is at the right place to look at the application of all he knows.

Candidly, I was feeling like all the can SIP save Skype discussion was a waste of time. My thoughts were that the courts were going to be the place where this got settled and not in the standards bodies.

However, I was mistaken. While I believe much of the knowledge about NAT traversal came from the capabilities embedded in Paradial, the world was off chasing the use of SIP as a solution.

Upper management found a strategy at a deeper level. Namely to make it so that Skype now had the benefit of Jonathan (Prior Art) Rosenberg.

If ever there was someone who had been looking at the issues of NAT traversal Jonathan has been the guy. From the development of MIDCOM, STUN, ICE, TURN and of course SIP, Jonathan has been there.

Mind you, the addition of another Jonathan at Skype also indicates where the company is heading even after being acquired. You can think of Jonathan as being at the beginning of SIP coming somewhat full circle. From adapting the Web model to telecom to now guiding the SIP model into the Enterprise, Jonathan is going to be well positioned.

Did you buy your car to access the road?

2009-11-02T13:09:50Z

Roger Von Oech, the creator of the Whack Pack, often looks to spur creativity by asking questions that are not direct but would have a parallel. So I asked the question to understand the nature of the access point to the Internet, which is your phone, home network or some other connection. You buy a car with the assumption that your ride on roads.

Are we at the point where you buy a device assuming it has connectivity to the Internet?

What if the device starts at Google?

What if the device only gives you Apple approved sites?

What if Microsoft made it a closed system?

Note these are not the names associated with the access fees you pay, but having everything to do with the regulations being discussed.

We are at interesting stage of discussion in Washington about the future of the Internet. We could make a case that it is an irrelevant discussion since the Internet has never been designed to be regulated by a single country. However for the 200 M plus of us that live in the US, these issues are real.

In the Wall Street Journal today, L. Gordon Crovitz did a nice job talking about the goings on in Washington. Markey and McCain giving opposite views as well as the Freedoms / Principles expanded by Chairman Genachowski.

One thing that Washington may be missing is the insight by Craig Labowitz shared at the joing meetings of NANOG/ARIN. It was very insightful about the technological innovations that are reshaping the Internet.

In the presentation there is cause for concern, in the fact that 50% of the Internet's traffic is aggregating into 150 sites. It used to be thousands. So Media control may be happening to Internet as well. However these 150 sites are not just carriers or media companies, so the rules and roles of regulators are not a match to this next generation. We could of course redefine Media to include them.

The reality is the Internet is progressing in its own policing with technology. So where is the bottleneck? And is it a smoking gun, a slow adopter, or some market power that represents the problem?

My own take is that its slow adoption, so I applaud the administration for its BTOP program, because the last mile is the place where you attach your device. And back to the car metaphor, you want to hit the open road as soon as possible. Trying to regulate the open road by your driveway specification seems like a bad strategy.

Report Excerpt: Market Launches Keep Clearwire on Target

2009-10-20T23:25:13Z

Editor's note: The following is an excerpt from our latest quarterly report on all things Clearwire, the CLEARWIRE NTK OCTOBER 2009 (need to know) report, available now for the low low price of $4.95. In this excerpt we talk about how Clearwire's on-time, on-target market launches in Atlanta and Las Vegas, as well as a host of smaller cities, have kept the company on target with its ambitious 2009 rollout plans. For the full report, order online here. Report excerpt follows:

Vegas, Atlanta and Silicon Valley - but where is Chicago?

Easily the most positive sign for Clearwire during the hot months was its on-schedule rollout of services in Atlanta and Las Vegas, the two bigger markets Clearwire had said it would launch during the summer -- and did. Perhaps catching many WiMAX watchers by surprise was Clearwire's August/September launch of an additional 10 markets for its new, mobile WiMAX services -- a list that included several small Texas towns like Lubbock and Abilene, as well as Boise, Idaho, and Bellingham, Wash.

The quick addition of the smaller markets was a pretty easy strategy to figure out if (like us) you had studied Clearwire closely. Since Clearwire has said many times that the hardest and longest task of launching any new market is getting its towers sited, approved and constructed, it stands to reason that any market where the company already had a tower position could be converted to the newer mobile WiMAX service pretty simply, with maybe an antenna change and some new networking gear on the back end.

At the end of September 2009 there were already reports surfacing about Clearwire quickly upgrading pre-WiMAX customers in some of its remaining 40 old-school markets, and on Oct. 1 the company "lit" two smaller markets (Milledgeville, Ga., and Salem, Ore.), while also making services available in Philadelphia.

Not as meaningful from a subscriber number but worth its weight in market influence was Clearwire's quick launch of its planned "testbed" network for developers in Silicon Valley, with separate clouds covering the campuses of Google, Cisco and Stanford University. Though some saw the testbed launch (which was announced back in May) as a public-relations stunt, from a business standpoint it seems to make perfect sense to put the service in front of folks who make up what is still arguably the world's foremost center of technological innovation and investment.

According to Clearwire, it will offer select subscriptions in Silicon Valley for free, while allowing any other developers in the area to sign up by joining the company's developer program, and then purchasing approved client gear for $50.

In commercial markets, Sidecut Reports was fortunate enough to be on hand, in person, for the "official" launch of services July 21 in Las Vegas, where we learned the following lessons: 1) Clearwire is going to be intensely local with its promotions going forward, which means that national roaming is not going to be a big selling point; 2) The company seems to be putting value ahead of mobility, which we think is a smart move since without a smartphone device,WiMAX isn't as sexy as, say, an iPhone 3GS or a Palm Pre; and 3) the company is going to enlist as many resellers as possible, from the very big (like Comcast and Sprint) to the very small (single-owner shops and mall kiosks) to help get the word out.

To get a feel for how this will roll out, consider the Clearwire sales footprint in the greater Las Vegas metro area: According to Clearwire, it only plans to operate five "branded" outlets in Vegas, including two storefront operations and three mall-based kiosks. The balance of the company's contracts will be sold by a list of 80-plus authorized resellers, including sales locations inside six Vegas-area Best Buy stores, 24 Radio Shack locations, and the rest independent resellers. The key for Clearwire is that all contracts will be with the parent company, and not resellers -- so no matter who signs a customer up, Clearwire will own the billing relationship.

For all the Clearwire knowledge you NEED TO KNOW for the latest quarter, order our CLEARWIRE NTK OCTOBER 2009 report today for just $4.95 -- that's right, less than five bucks for a lengthy take on Clearwire market launches, device plans, business news and more.

Dear Congress; A Phone Number does not a Service Make

2009-10-12T15:48:36Z

In the last thirty years, the computing world has changed so much, that it is hard to remember the logic of roles and rules that existed and still drive the basis of law and leadership when it comes to telecommunication. Telecom has always been a service that has made a distinction between service and use. Telecom services were deliberately limited to enable the maximum amount of people to use the services for whatever activities they choose.

Enabling the network to be ubiquitous was accomplished by aggregating the costs of service between local services and long distance services. The cost of providing the connection (the local loop) was harmonized as much as possible with statewide loop costs and subsidization from the long distance market. However with the ubiquity achieved the opportunity to support specialized services enabled for the early focus of the Internet to be about the signaling on top of the phone network and not inside it.

A primary reason why the issues of the phone network were of no concern was that IP was distance insensitive, and connecting at the closest point on the phone network through dial up or private line was pretty efficient.

Now the technology and cost models of access are intertwined and efficiency in the network is not represented in any particular type of fee structure. Nor is there a clear distinction between accessing a service via the phone network, or an "Internet" service that replaces the phone network.

However, certain principles of the phone service have been considered primary and certain have been considered secondary. Primary services are your origination point for phone calls and have the responsibility for delivering calls to the 911 network.

Until the Internet, the primary way to innovate on the phone network was to use the network for secondary services; the phone company did this themselves with solutions such as Wide Area Telephone Services [WATS] and 800 numbers. However the place where people were doing more than just talking was with computer networks, ring back services, and call centers. These connections all managed the call after the handoff from the phone network and continued routing the call for innovative services.

With the Internet's inter networking ability to support connectivity on the network without a usage charge these solutions rapidly to advantage to stay connected to provide unique synergies that added value without being a primary service.

Today with many people using wireless as their primary service, and the ability to provide smart computing devices to the user we again stand at a point where the basis of the regulation of the past no longer matches to the realities of technology. Today a smart phone can have an application as a result of being part of the Internet or an app store, before there was an app store many companies provided services via these secondary lines.

If you treat all phone numbers as a primary service solution, the result is that the innovation fostered by the ability to connect via the telecom network will never be offered to the telecom network. On the Internet side the ability to innovate will not be associated with the network connectivity when accessing the Internet but only to the applications.

Services that do not support primary line functions of origination, or are "free" services should not be driven by the same rules as primary line solutions.

Many people speak about the issues of Net Neutrality without real market drivers behind their rationale. The principles discussed by FCC Chairman Genachowski assume a controlling factor by the access provider.

However at the core of the discussion should be relationship of ubiquity and usage. Service levels and performance

Viewing any service with a phone number from the perspective of telephonic service is as antiquated as the term, which was used to distinguish telephones from telegraphs.

The goal should not be on extending the regulation that tried to curtail monopolies, but to encourage the innovation, which will bring new types of services even to the plain old telephone services.

GoogleVoice is one such service as are many other innovative companies. Via GoogleVoice you can route calls you can initiate signals to originate calls to your primary service number. It combines the web, video and phone services.

As the Promoter for the Fight: I would like to get credit

2009-10-07T19:11:14Z

Yesterday, we taxed the system of a friends conference server with a call about Net Neutrality. It was covered by many other media outlets, which did not give us credit for the call. It included Hank Hultquist of ATT, Todd Daubert of Kelley Drye and Dave Erickson of Free Conference call. Rick Whitt was to be on the call, but had to pull attend to other matters. It was a great call. And as usual I was my orthogonal self. I may not be a lawyer, but I make any Congressman proud in confusing the issues.

If you want to listen to the call for yourself listen hear.

Of course, All parties have agreed to come back for round 2 in Miami January 20th at 4GWE

Although Dave Erickson will part of another session about the issues of Applications Compensation.
