WiMAX: The Best of Times, The Worst of Times...

November 20, 2008

A new report has just come out from Informa, and the findings have the report's author channeling Dickens.   "It's the best and worst of times for WiMAX," says Mike Roberts, principal analyst at Informa, and author of WiMAX Broadband Convergence: Emerging Fixed, Portable & Mobile Internet Markets - 2nd Edition.   According to Roberts:   WiMAX is a tale of two markets - one being WiMAX as an emerging technology gaining significant momentum in the last year, and the other being the larger converging broadband market, where the runaway success of rival mobile broadband system HSDPA and the acceleration of LTE threatens the opportunity for WiMAX in some markets.   On the WiMAX side of the ledger, we find the launch of services by major operators such as Sprint/Clearwire, commitments to WiMAX by major proponents such as Google, and the long-awaited arrival of WiMAX notebooks and other devices.   On the flip side, HSDPA has reportedly become a runaway success in many markets worldwide, and emerging LTE technology is ramping up and has secured the support of many major mobile operators.   Of course it remains to be seen what will be written in the final chapter of this "tale of two markets." It's clear that we all have great expectations, and while in telecom there is always ample opportunity for at least two market entrants, it's a distinct possibility that for one of these two combatants, it will indeed be a bleak house.    

Taking a Deeper Look at the Clearwire Deal -- Again

November 24, 2008

With the shareholder approval finally taken care of, the massive deal to build a new nationwide WiMax network under the Clearwire (Nasdaq: CLWR) name can (finally!) now begin in earnest. While those of us who have been following the events over the past year know pretty much what is on Clearwire's immediate to-do list, for those who are playing catch-up may we suggest you order the new, updated version of our WiMax report, which includes a comprehensive study of the "new" Clearwire WiMax deal and its $3.2 billion of investment from a group that includes Google, Comcast, Intel and Time Warner Cable.

When you read the report you will learn:

-- The new opportunities and challenges for Clearwire's national focus, which is a departure from previous plans

-- The motivations for Google's $500 million investment, which go beyond business goals for search and mobility to include public-policy goals

-- Why the big telcos, AT&T and Verizon, may not see WiMax as a prime competitor (even as they step up marketing and lobbying efforts to make life harder for WiMax)

-- Why cable providers like Comcast may be looking to WiMax to expand their user footprint beyond its current regulatory limits

The report also contains a WiMax technical and historical backgrounder, as well as an updated look at the WiMax business opportunities for enterprises, investors and entrepreneurs in markets including mobile Internet businesses, software development, and mobile device manufacturing.

Clearwire Mum on Xohm Launches, Says LTE a Possibility

December 1, 2008

The new Clearwire just concluded its first conference call with analysts and press types, and while some questions did get answered there were more questions raised by the quick interaction, including a declaration that Clearwire might switch from WiMax to Long Term Evolution (LTE) as a technology base sometime in the future.

While declaring mobile WiMax as the best technology currently available for 4G services, Clearwire CEO Ben Wolff said that LTE (which has been embraced by AT&T and Verizon for their respective 4G wireless data plans) will most likely gain some traction, and as such will be considered as a possible future alternative for Clearwire.

"Mobile WiMax and LTE have a lot in common," said Wolff, who added that Clearwire will build its network infrastructure in such a fashion that will allow the company to move to, or add LTE technology "if we decide it makes sense to do so."

While such a switch would be at least two or three years in the future, some more immediate Clearwire concerns -- including the pending launches of WiMax services in Chicago and Washington, D.C. -- were put on hold, at least until the company's new board of directors can convene for strategic talks. Though Clearwire merger partner Sprint had talked confidently of launching its Xohm-branded services in Chicago and D.C. before the end of 2008, Wolff said Monday that the company didn't have any launch news to share.

"We need to get together with the new board and walk the board through [the planned network launches]," Wolff said.

Clearwire's Wolff: 'Full Speed Ahead' with WiMax

December 6, 2008

Despite what you may have read, heard or thought, there is no chance of Clearwire Corp. (NASDAQ: CLWRD) abandoning WiMax technology anytime soon. Though Clearwire CEO Ben Wolff did talk Monday about the possibility of adding support for Long Term Evolution (LTE) to Clearwire's technology mix sometime in the future, in an interview Thursday morning Wolff left no doubt that Clearwire is solidly behind WiMax, and considers it the best (and only) 4G wireless technology currently available for deployment.

"We have no doubts that we made the right decision" to pick WiMax as the technology for its wireless network rollout, said Wolff in a phone interview. "We are going full-speed ahead with WiMax. It offers a more robust [Internet] experience, at a more economic price point, than any other technology available today."

The confusion over Clearwire's commitment to WiMax came in the wake of a Monday conference call, which was used mainly to report the details of the completion of the merger of Clearwire with Sprint's WiMax assets, and the new branding of its "Clear" WiMax services. At one point in the call, Wolff talked briefly about the possibility of Clearwire adding support for LTE in the future, should the standard become widely adopted and deployed.

The Sprint WiMax/3G Card: (Almost) Ready to Roam

December 19, 2008

The question about how WiMax provider Clearwire would answer the national-roaming question got a little bit clearer Wednesday, when Sprint officially announced its long-promised 3G/4G hybrid device, a USB dongle that lets a laptop user connect to both Clearwire's WiMax and Sprint's 3G cellular networks.

For right now, that former option means one city -- Baltimore -- where the service previously known as Xohm has been running since September. But Todd Rowley, vice president of Sprint's 4G business unit, told us Wednesday that the new device will work in all the networks being readied by the new Clearwire, starting with Portland, Ore., sometime "by the end of Q1."

Without getting too much into specifics, it isn't the technology holding the card back but Sprint's back-end ability to support it on the "Clear" networks -- like Portland's, whi  ch is set to publicly launch Jan. 6. So yes, Rowley said, the device will eventually allow roaming users to link up with Clear WiMax networks wherever they may be launched, maybe not right when they launch but soon after.
In terms of value, the hybrid device is kind of a hybrid offering -- it's not as cheap as the straight-WiMax    offerings and it comes with the standard (for cellular data) two-year contract and early termination fees. You also can't use the 3G service for VoIP calls (and it ha  s bandwidth restrictions), though Skype over the 4G service should work just fine, Rowley said.

Azimuth Looks Ahead After Successful 2008

Open Source Net Neutrality via Google

April 10, 2009

Just in Time for wireless broadband to start playing out Google has started the M Lab and M stands for Measurement of your connectivity.  The beauty of this place is not in the tools, many of which have existed for some time but the gathering point for the information.

It has its own blog, and I would suggest that it is a good spot for network engineers everywhere to gain perspective.

However, this is not a Wheatstone bridge.  Being able to tell you are being throttled is not necessarily telling you who is throttling you. What it does it tells you there is smoke (if you were looking for the fire).

This is just the beginning for this site. 

It may be that alternative service providers find this place to be a source for third party corroboration.

As the edge delivers applications it may be the best place to look at where problems occur.

I am somewhat disappointed that it does not have a cloud component or a widget available.

However, it's a starting point and as the wireless network moves to IP in our 4G world, I am sure we are going to need tools like this.

Skype vs. DT And now the Ref Steps in..

April 13, 2009

A friend sends a note..

The European Union (EU) is reportedly preparing guidelines for wireless
carriers to allow VoIP services like Skype to run over their networks,
including punishments if they don't comply. EU commissioner (Viviane Redding) said "action" should be taken against carriers who use market power to block new services.

Apparently, the EU already has prepared a draft position to open up
smartphones to VoIP services, but lawmakers want to refine the language.
Right now, each EU country has to decide how they want to deal with blocked
services on an individual basis, and the EU is asking countries to take
legal action against carriers that "block innovative services." Deutsche
Telekom's decision to block Skype may prompt the EU to look into antitrust
charges against the carriers.

I had already commented and will continue to do so.

Cisco Delivers WiMAX Wake-Up Call With Clearwire Deal

May 14, 2009

After Cisco bought WiMax radio supplier Navini in October 2007, industry watchers have waited and wondered why the biggest networking vendor wasn't doing more with WiMax in the U.S. market. Now after Wednesday's announcement of a multi-year deal between Cisco and Clearwire, the waiting is over -- and you have to think Cisco just delivered a big wake-up call about WiMax to Silicon Valley and Wall Street in one big move.

What really made the deal big news was the inclusion of Cisco's pledge to ship a mobile WiMax end-user device before year's end. The other part of the deal, which involves Clearwire using Cisco gear in its core IP network, isn't so surprising -- in any IP network of Clearwire's size, you might be more surprised not to find Cisco gear in the wiring closets.

But by pledging to develop end-user devices, Cisco is signaling to the rest of the industry (and investors, if they are listening) that WiMax is more than a curiousity.
