Clearwire’s Launch Party in Portland

Posted by Sam Churchill on January 6th, 2009

Clearwire (or is it Clear now), today presented their Portland, Oregon, Mobile WiMAX system to the press and analysts. It was Clearwire’s first implementation of Mobile WiMAX in the United States. While Clearwire now provides pre-WiMAX broadband to some 400,000 subscribers in 46 markets, the earlier technology does not roam, nor can it be used in small handheld devices.

Clearwire’s Mobile WiMAX now provides multi-megabit speeds throughout a 700 square mile region around Portland, with a potential user population of nearly 1.7 million people.

Ben Wolff, CEO of Clearwire, which closed their 3.2B joint venture with Sprint, Comcast, Time-Warner Cable, Google and Intel, this November, demonstrated the technology using a video conference with Portland’s new mayor Sam Adams. Live cameras on Light Rail trains were also shown, while attendees could also ride the city’s Streetcar and special buses that demonstrated mobile broadband connectivity and seamless handoff between cell towers.

Wolff said WiMAX had three main advantages over cellular; (1) spectrum, (2) an all IP Network and (3) and open Internet model, allowing all manner of devices and applications to use the spectrum.

Almost half of all iPhone users prefer WiFi rather than cellular’s 3G network, said Wolf, with data traffic for mobile phones now comprising some 20% of revenues from cellular carriers — and growing fast.

Why Portland? Because it has a tech savy population, a large contingent of Intel engineers and it is convenient to their Kirkland, Washington, headquarters.

Sean Maloney, Intel’s VP of Marketing, explained Intel’s pioneering work with networking, including the development of Ethernet in the early 1980s, Wi-Fi development in 2000-2001, and the development of WiMAX standards in 2003 to today. Ron Resnick, President of the WiMAX Forum was also in attendance, but did not speak. We’ll post some video interviews from the show later.

Scott Richardson, Clearwire’s Chief Strategic Officer, proclaimed, “Portland is now the fastest unwired city in the West.” He showed live cameras aboard Portland’s Light Rail train to prove the point and announced that Clearwire was donating 25 WiMAX modems for city Police cars. The new mayor approved. “It will improve on our ability to provide services to the public”, said Sam Adams.

City employees from a variety of departments were also at the press show. Applications such as location tracking of dump trucks and other vehicles as well as the city’s electronic parking meters were also mentioned (unofficially).

The City of Portland has no skin in this game or legislative oversight. Clearwire, like other cellular operators, mounts their radios on cell towers, not on lampposts or public rights of way, and negotiates with tower or building owners.

No access points were installed on the trains. Notebooks and small netbooks, equipped with Motorola’s tiny USB WiMAX dongle, provided the connectivity directly from nearby towers. Intel and Clearwire also provided small buses with a large plasma screen in the back and WiMax equipped Netbooks for individuals. Streaming video, speed tests and web surfing were demoed along the route, while handing off to ten or so cell towers.

The WiMax connection, directly from the laptops to the cell towers, held up pretty well and were relatively glitch-free. Impressive since the small USB dongles were inside moving vehicles.

Ben Wolff said rolling out broadband wireless service is not a piece of cake that can be turned on in a few months (although the radios can be installed in less than a day). “It takes 1-2 years to launch a market,” said Wolff. Zoning requirements involve lots of municipalities. Even adding one radio to an existing tower requires a lengthy permitting process, said Wolff.

I asked Wolff how the cost of wiring a city compared with WiFi and Cellular. Cost of the backhaul and all the WiFi antennas makes it 3-4 times more expensive than WiMAX, said Wolff, with cellular infrastructure costing 10 times more than WiMAX. “Our network was designed for data,” he said. Clearwire is also adding extra capacity from day one, making it easier to expand.

Wolff expressed confidence that the WiMAX system would catch on, eventually grabbing a 25% share of the market. He also expected users to soon use 2-3 times the data capacity they do now.

Wolff said that Clearwire would not be able to announce which cities were next for either Sprint or Clearwire until after the Clearwire board makes a decision in the next few weeks. WiMax watcher ThinkEquity is predicting that Clearwire will launch a total of nine markets this year, suggesting “a slower revenue ramp and lower levels of cash burn than had the original plans gone forward,” says Unstrung.

The pre-merger Clearwire has also built out networks in Atlanta, Las Vegas and Grand Rapids, Mich., none of which have yet launched, though Clearwire never set any specific target date. Sprint had also planned to launch Washington, D.C., and Chicago by the end of 2008.

Clearwire will hold grand opening events at its three Portland retail stores from 9 a.m. to noon on Saturday, Jan.10th. The stores are located at: 15th and Broadway, 92nd and Sunnyside (Clackamas Promenade), and Burnside and 23rd Place (Uptown Shopping Center). Many area Malls also have Clearwire Kiosks.

The marketing is now kicking into high gear, both in Baltimore, Maryland (the first Mobile WiMAX city in the United States) and Portland, Oregon (the second). Whether the poor economy will help or hurt the nascent wireless service is unknown.

Macworld Expo 2009

Posted by Sam Churchill on January 6th, 2009

Apple’s last Macworld Expo starts today — without CEO Steve Jobs’s traditional keynote. Jobs put out an open letter yesterday saying he’s not dying, but has a hormone imbalance. Jobs will continue as CEO while he is regaining weight in what he called a “simple and straightforward” remedy.

It’s hard to top the live coverage from Engadget or Gizmodo.

A new Mac mini is rumored for Macworld 2009. The new model includes a Mini DVI connector as well as a Mini DisplayPort. With these two new connecting points, users could enable two displays at the same time.

A new 17-inch unibody MacBook Pro with a fixed internal battery is also expected along with a refresh of the iMac line. A 28-inch model, a set of 24-inch devices, and two 20-inch variants are expected by MacNN. The company could be transitioning to NVIDIA-based integrated graphics with the 20-inch refreshes, while the 28-inch iMac is said to feature an Intel i7 Core processor.

Enjoy. I’m off to Clearwire’s WiMAX rollout in Portland.

Clearwire Launches in Portland, Oregon

Posted by Sam Churchill on January 6th, 2009

Today marks the official launch of Clearwire mobile WiMAX in Portland, Oregon. It’s the 2nd major Mobile WiMAX rollout in the United States, after Sprint’s October rollout in Baltimore. Although Clearwire (now “Clear“) has several dozen pre-WiMAX cities, this is their first using Mobile WiMAX.

Intel, which has been testing the system in the region for nearly 18 months, is betting big on the WiMAX flavor of broadband wireless technology because it was more data-centric and had less royalty/operational overhead. It can be used in both licensed and unlicensed frequencies.

Intel has invested $1.6 billion in Clearwire and will rollout WiMax enabled Centrino 2 laptops. With WiMax built into a PC, there’s no need for external hardware.

Motorola base stations have been installed in nearly 300 Sprint cell sites in the region and the service has been available to the public since December 1, 2008 (when I signed up). Clearwire stores are open, area Malls have staffed kiosks, and sales tents are popping up on downtown sidewalks.

Clearwire shareholders agreed in November on the $3.2 billion merger with Google, Intel, Comcast, Time Warner and Sprint to build a new national high-speed wireless network.

Clearwire is facing off against giant telecom companies. AT&T, Verizon and T-Mobile, virtually all the major cellular providers in the United States (except Sprint) have backed the incompatible LTE standard. LTE is expected to begin initial service in 2010 with major rollouts in 2011-2012.

The United States has some 260 million cellular subscibers. If just 10 percent of those users used LTE, that would be 26 million.

Sprint and Clearwire say their advantage is a lot of spectrum and a cost/effective infrastructure. WiMAX uses routers similar to inexpensive WiFi hotspots. The licensed spectrum, power and rugged protocol provides multi-megabit speeds — virtually anywhere.

While WiFi Metropolitan networks, like MetroFi and Earthlink, promised “free”, ad-supported networks, they proved to be unreliable and expensive. Municipal Wi-Fi networks were not free — they cost $65K-$100K per square mile to build, or around $10M to cover a 100 square mile city.

WiMAX, by comparison, can cover between 3 to 10 square miles from a single cell site. WiMAX, say proponents, is one tenth the cost of cellular or municipal WiFi and delivers better speeds. Cellular range with Wi-Fi speed. Twice the speed. Half the cost.

Intel will begin shipping its WiMAX/Wi-Fi 5050 PCI card ($50) later this year, which will enable WiMAX on Centrino 2 laptops. The Echo Peak module (left) shares MIMO antennas embedded in a laptop lid for both WiFi and WiMAX.

In Centrino 2 laptops, two versions of “Echo Peak” are available: 1×2 and 3×3 MIMO configurations. A 1×2 configuration in the 5150 (Echo Peak) module means one antenna is used for uploading, while two are used for downloading. Three antennas are utilized with the 5350 Echo Peak module for faster speed with longer range (but requiring more power). Taiwan-based network-equipment makers, including Asustek, Gemtek and Universal Scientific Industrial (USI), are likely to be the contract makers for the Echo Peak and Shirley Peak modules.

For UMPC and MID devices, Intel is utilizing its next-generation ultra-mobile platform – codenamed “Menlow”.

Sprint and Clearwire say their new WiMAX network will support both open access and wholesale access and will have far more spectrum than cellular providers — with over 100 MHz available in most large cities in the United States. That’s enough to deliver a triple play — data, voice and video — anywhere.

Clearwire projects 140 million people in the United States will be covered by their Mobile WiMAX system by the end of 2010 — and expects 4.6 million paying subscribers at that time.

If it works out, Intel may sell a lot of mobile device chipsets, Sprint would get a high speed network, cable operators could have their own (wholesale) wireless network, and Google could find a home on your mobile device, selling click-though ads with video chat and Google Maps.

Clearwire expects WiMAX will be built into cell phones later this year, perhaps displacing cell phone data plans with faster, cheaper Mobile WiMAX. The WiMAX Forum projects 133 million WiMAX users globally by 2012, with most of the growth in Asia and Europe.

What will happen is anyone’s guess. Whatever the outcome, it’s got the elements of good drama.

Market success may come through the back door with apps on mobile internet devices (reviews).

Worldwide smartphone sales totaled 32.2 million units in the second quarter of 2008, a 15.7 per cent increase from the second quarter of 2007, according to market researcher Gartner. Smartphones are currently about 15 percent of the entire mobile phone market, but are predicted to grow to 40 to 50 percent within the next five years. Informa forecasts subscriptions to UMTS/HSPA will number nearly half a billion worldwide by the end of 2009, and will pass the one billion mark in 2012.

Mobile Data Traffic by Application is expected to shift to video and internet access. Platforms like Android and Symbian Foundation could make cloud applications truly magical.

Mars Rovers: 5 Years On

Posted by Sam Churchill on January 5th, 2009

The Mars rovers are celebrating a remarkable five years on the Red Planet (video), notes the BBC.

The first robot, Spirit, landed on 3 January, 2004, followed by its twin, Opportunity, 21 days later.

It was hoped the robots would work for at least three months; but their longevity in the freezing Martian conditions has surprised everyone. Nasa lost contact with its more recent (but static) Phoenix lander in November (below).

The rovers’ data has revealed much about the history of water at Mars’ equator billions of years ago.

Together, the rovers have driven more than 20km, and returned more than 36 gigabytes of data. This has included a quarter of a million images.

Spirit is exploring a 150km-wide bowl-shaped depression known as Gusev Crater. It has found an abundance of rocks and soils bearing evidence of extensive exposure to water. Opportunity is on the other side of the planet, in a flat region known as Meridiani Planum. Some of the rocks seen by Opportunity were once “drenched” in water

The rovers are now showing some serious signs of wear and tear. Spirit has to drive backwards everywhere it goes because of a jammed wheel; and Opportunity’s robotic arm has a glitch in a shoulder joint because of a broken electrical wire.

November 20, 2008, marked the end of the Mars Reconnaissance Orbiter’s primary science phase. The orbiter, which also relayed pictures from the rovers, returned 73 terabits of science data, more than all earlier Mars missions combined. NASA killed the 2009 Mars probe launch. The mission was supposed to send a new rover to Mars in October 2009 to study the planet’s environmental history and determine if conditions are, or ever were, able to support life. Officials cited cost concerns.

In 2011, a more capable Mars Science Laboratory (MSL) will be launched.

The Mars Phoenix Lander was launched on 4 August 2007 from Cape Canaveral and landed on Mars in May, 2008. A Mars trip takes 10 months. The Mars Lander surpassed its original three-month mission, lasting five months. The HiRISE camera, on board Mars Reconnaissance Orbiter, photographed possible landing sites. It was designed to study the surface and near-surface environment of a landing site in the high northern area of Mars. The primary science objectives were to; determine polar climate and weather, study interaction with the surface, and composition of the lower atmosphere around 70 degrees north for at least 90 sols.

The static Phoenix Lander, which touched down on 25 May of 2008, is supported on three static landing legs (no wheels). The science experiments and a robotic arm are mounted on the base. Communication was primarily through a UHF relay via the Mars 2001 Odyssey orbiter, but Mars Reconnaissance Orbiter and Mars Express can also be used as relays. The (very) static Phoenix also has a steerable medium gain X-band antenna to provide communications directly with Earth.

If the Phoenix Lander comes back to life on Mars, Twitter users could be among the first to know. NASA added a Twitter page, enabling the robotic interplanetary explorer to answer the hot micro-blogging website’s trademark query: “What are you doing?” Here’s its twitter feed.

Both Mars Express and the Mars rovers use the same communication protocol. This protocol, called Proximity-1, was developed by the international Consultative Committee for Space Data Systems, an international partnership for standardizing techniques for handling space data. CCSDS provides a forum for discussion of common problems of space data systems. Some 346 missions utilize the protocol.

Text Solutions For Clogged Cell Networks

Posted by Sam Churchill on January 5th, 2009

Wireless carriers in Washington DC are expecting an explosion of cellphone traffic on Jan. 20, says the Washington Post. That’s when millions of visitors pour into Washington to welcome the new president.

Carriers are erecting extra cell sites to boost voice and data capacity, but two DC companies are also working on text messaging solutions which require much less bandwidth and can get through even when voice networks are choked.

  • TeleCommunication Systems in Annapolis says the text message President-elect Barack Obama’s campaign sent to 6 million voters last year when he won the Democratic nomination.

    “That message blast was not properly coordinated with carriers,” he said, so the influx of messages was interpreted as a cyber-attack by some networks, causing the traffic to be blocked or delayed. That was because many carriers store a message for a short time before delivering it. Now TeleCommunication Systems has a product that delivers text messages immediately to save bandwidth.

    The company is also working with the Federal Communications Commission to develop a location-based broadcast system so weather alerts and public safety warnings can be sent to the cellphones of residents of a geographic area. TCS technology has delivered a record 130 billion text messages during the first three quarters of 2008 and expects to deliver close to 200 billion messages for the year.

  • AppTek of McLean is hoping many inauguration attendees will use its product that translates text messages into different languages. The company has licensed its technology to other online firms including TransClick.com, isec7.com and OnsetTechnology.com. Consumers can download the software to their BlackBerrys, PDAs and other smartphones.

    AppTek is also working with DARPA to develop handheld devices that can translate two-way conversations in real time. The device is intended for use by military and intelligence workers.

Both firms hope the mass text messages that helped fuel Obama’s campaign success will continue long after the inauguration, says the Washington Post.

Jobs: Hormone Imbalance

Posted by Sam Churchill on January 5th, 2009

Apple’s last Macworld Expo starts tomorrow — without CEO Steve Jobs. This morning Jobs put out an open letter to address questions about his health.

Jobs’ letter boils down to “no, I’m not dying, but I am ill, and so I’m not up to doing the keynote.” He explains that, as many onlookers have noted, he’s “been losing weight throughout 2008″.

Jobs said the cause appears to be “a hormone imbalance that has been ‘robbing’ me of the proteins my body needs to be healthy. Sophisticated blood tests have confirmed this diagnosis.” Jobs will continue as CEO while he is regaining weight in what he called a “simple and straightforward” remedy.

A new Mac mini is rumored for Macworld 2009. The new model includes a Mini DVI connector as well as a Mini DisplayPort. With these two new connecting points, users could enable two displays at the same time. A new 17-inch unibody MacBook Pro with a fixed internal battery is also expected along with a refresh of the iMac line. A 28-inch model, a set of 24-inch devices, and two 20-inch variants are expected by MacNN. The company could be transitioning to NVIDIA-based integrated graphics with the 20-inch refreshes, while the 28-inch iMac is said to feature an Intel i7 Core processor.

Meanwhile, over at CES in Las Vegas, the show goes on. Engadget, Gizmodo and C/Net have wall-to-wall coverage.

Here are 25 hot products at CES including Cables To Go.

The USB to VGA Adapter Kit is a wireless VGA solution for connecting a computer to a monitor or projector. The kit lets users wirelessly display video content from a computer to a remote monitor, projector or television up to 30 feet away. The Wireless USB to VGA Adapter Kit uses Ultra-Wide Band and operates in the frequency of 3.1GHz to 4.8GHz (WiMedia Band Group 1).

Other highlights include Nvidia’s $199 glasses that turn compatible monitors into three-dimensional displays, using LCD shutters to quickly alternate between left and right images. The wireless glasses come with an adapter that plugs into a regular USB slot.

Connect Minoru to your PC and he will come alive, his eyes will light up and he will be looking at you in 3D.

Paolini: 3.650 GHz Works

Posted by Sam Churchill on January 2nd, 2009

Monica Paolini at Senza Fili Consulting is one of the sharpest minds in the wireless business. She has been providing advisory support on wireless data technologies and services since 2003.

Her November 2008 Newsletter provides an in-depth analysis of the 3650 MHz band. A light-licensing scheme is used for the 3.65GHz band. It basically requires the operator to fill out a form for the FCC. Paolini says the band is still largely untested because of its recent introduction, but the results so far are very encouraging.


Commercial equipment based on WiMAX with the necessary FCC approval is now available from multiple vendors. In some cases where vendors have invested in Interoperability Testing (IOT), operators can use interoperable gear from different vendors within the same network.

As of September 2008, 420 operators nationwide have applied for or received a license, and some of them have launched commercial services using WiMAX-based equipment.

The 3.65GHz band has good propagation characteristics that enable Non-Line-Of-Sight (NLOS) operations. This results in lower deployment costs and better coverage.

The additional benefit of the 3.65GHz band is that it brings wireless operators access to WiMAX-based technology, which before now was available only for licensed spectrum. WiMAX supports improved spectral efficiency, lower per-bit costs, and Quality of Service (QoS) for carrier-grade voice services and enterprise Service Level Agreements (SLAs).

One of our latest white paper (pdf), was prepared for Redline Communications and provides an overview of the opportunities for wireless operators in the 3.65GHz band in the US. It starts with a discussion of the key regulatory requirements and the available technology options, and continues with two case studies of operators (Nex-Tech and Rapid Link) that have successfully launched commercial services in the 3.65GHz band.

But not everyone agrees with Paolini.


Hey Sam, just read your recent post on Paolini: 3.650 GHz Works.

I have a few comments I’d like to make. We were one of the first to apply
for a 3.65ghz license in our area, and we were the first to register base
stations and actually put the band to use on the west coast (I think you
may recall my press release around june 2008). We’ve run into some rather
difficult issues with this new band.

The assumed safe guards from operating in this new band are non-existent.
Other then the FCC collecting $200 for the license, they do not play an active roll
in managing disputes within the band. We’ve had several competitors also roll out
WiMAX equipment in the same area, in this band, which has caused severe
interference (worse then what would be experienced by an 802.11 or Canopy
network). The FCC does not require one to register the operating frequency
or channel size; which opens up the band for abuse by anyone with about
$500 in their pocket.

Carriers thinking that they can roll out a reliable, dependable WiMAX network
in 3.65ghz should think again. All it takes is one competitor (or idiot)
with a little time and money to bring an existing network to its knees.

Also, I disagree with Monica Paolini’s assessment of the 3.65ghz bands
Non-LOS characteristics. Due to the FCC’s imposed limited EIRP, along with
the inherent attenuation issues as you venture further up the spectrum;
we’ve found that 3.65ghz is not an ideal band for non-LOS. Considering
this and the above mentioned issues, a carrier would be foolish to deploy
Non-LOS in this band.

I find her motives dubious in regards to her glowing, optimistic
assessment of the 3.65GHz band, especially considering her reseller
relationship with Red Line. Based on my experience, her article indicates
to me that she has no field experience with the band, or Red Line WiMAX
products.

Regards,

Eric Ozrelic
President Webformix

Mr Ozrelic provides a valued 2nd opinion and perspective from actual field experience. But I don’t believe Senza Fili Consulting acts as a reseller of gear.

According to Senza Fili’s web site, “We have in-depth expertise in financial modeling, market research, business plan support, business development, RFP and vendor selection support, due diligence, white paper preparation, and training.”

Eric Ozrelic adds:


If I had my way, the FCC would revise the 3.65ghz rules to allow for
channel registration, and some sort of coordination check BEFORE another
carrier is allowed to register a base station in/around existing base
stations.

I’d also like to see them open up the upper 25mhz for restricted
protocols, and allow for more power. 2 watts per mhz used (up to 10watts
EIRP) would be a nice start.

Last but not least, if the FCC doesn’t address these issues, we very well
may see the same situation that’s happened with the other unlicensed
bands. Whoever deploys the most robust technology with the greatest
interference rejection will ultimately be king of the hill.

The proof is in the pudding. Clearly, 3.650 GHz isn’t the answer for everyone.

For wide-area suburban coverage, licensed WiMAX using antenna techniques like MIMO, AAS, adaptive beamforming, SDMA, and uplink sub-channelization, may largely solve the problem of indoor penetration — at less cost than Wi-Fi per sq mile — with better reliability.

A typical licensed WiMAX base station at 2.5 GHz transmits at power levels of approximately +43dBm (20W), while the mobile clent typically transmits at +23dBm (200mW). There is a large difference between downlink power and uplink power, so while a mobile can easily receive transmissions from a base station, the mobile’s relatively low transmit power makes it difficult for the base station to hear it.

One way to combat this mismatch is with a technique called sub-channelisation. In effect, each mobile concentrates its power over a subset of all available sub-channels, and the other sub-carriers are simultaneously made available to other users.

Another technique to address the link imbalance is adaptive modulation (above).

In this case, the mobile transmits using a lower order modulation compared with the base station. Because the SNR required to receive QPSK or 16QAM is lower than 64QAM, using a lower order modulation allows the mobile station to communicate with the base station using less transmit power.

When sub-channelization, adaptive modulation and multiple antennas are combined, a network operator can effectively balance the uplink and downlink budgets. It delivers higher speeds to the cell edge.

But the additional costs for WiMAX licenses and gear may keep its advantages largely theoretical for smaller operators. Whether or not the unlicensed 3.65 GHz, 2.550 GHz, or “white space” bands (using unused tv channels) can successfully bridge the “digital divide” cost/effectively is still unknown.

Alvarion, Alcatel-Lucent, Motorola and Samsung together have nearly three-fourths of all publicly announced mobile WiMAX customers, according to Infonetics. In the third quarter of 2008, Alvarion overtook Alcatel-Lucent and Motorola in the mobile WiMAX market.
