WiMAX device ecosystem is growing – RCR Wireless News

3G cellular is all about data. If WiMax is growing for data, then 3G or 4G cellular may not be needed. Just 2G would be good enough for voice. As iPhone and iPad get popular,  concerns grow that wireless internet gets slower. Even voice gets stutter. This is because both data and voice use same network. It makes good sense therefore to separate voice and data in different network. That is, voice for 2G cellular network, and data for WiMax network , rather than both voice and data to 3G or 4G cellular. Voice is THE killer app in smart phone. Data should not compromise it. This is more true for many non smartphone users.  In this sense, HTC EVO 4G from Sprint is a very good approach. Sprint may need to lower the cost similar to 3G to make this more popular. Making cell phone for WiFi hot-spot is also a neat feature.


WiMAX device ecosystem is growing – RCR Wireless News.

HONOLULU, Hawaii–As WiMAX networks roll out across the globe, device manufacturers and operators are hoping to move beyond the dongle and computer modem to more innovative products, according to panelists at the Global WiMAX Business Development Forum. 

Even as Sprint Nextel Corp. gets ready to launch the HTC Evo 4G handset in a few weeks, global operators are hoping that WiMAX chips get embedded in more nontraditional devices. For example, in Pakistan, a WiMAX chip embedded into a television could be a way for the nation’s wireless broadband users to connect to the Internet, said Dr. Tanveer uI Haq, CTO at Pakistani WiMAX operator Wi-tribe. While there are only 7 million PC users in Pakistan, there are about 95 million cellular users and 95 million people who own TVs. 

The technology is available to install a chip in a set-top box, said Craig Miller, VP of marketing and business development at Sequans. The trick is getting the consumer electronics manufacturers to include the chip in the manufacturing process. 

As the WiMAX ecosystem develops, more products are getting embedded to support the various frequencies WiMAX operates in across the globe, said Kevin Jones, Intel Corp.’s Global 4G evangelist. Intel’s 6250 adapter, for example, supports 2.3 GHz, 2.5 GHz and 3.5 GHz as well as Wi-Fi and is in more than 200 netbooks. 

WiMAX operators also are interested in partnering with cellular providers to sell dual-mode handsets that marry 2G coverage for voice with 4G coverage for data. If operators ink those deals, device manufacturers will build products for them, but the carriers have to be able to sign deals with 2G cellular providers. 

WiMAX chips are going to be embedded in a number of M2M devices, including smart-grid modules, said Lars Johnsson, VP of business development and marketing at chip-maker Beceem. “Utility companies want to use WiMAX as a gateway into the home.” Video surveillance cameras are another opportunity, he said. Video apps can’t run on a 2G network so any kind of remote monitoring is another opportunity.

Panelists also questioned why Russian operator Yota failed in its attempt to bring a WiMAX handset to market two years, but a major difference between the Yota handset and Sprint Nextel’s Evo handset is pricing: While the Yota handset, manufactured by HTC Corp., cost $1,000, Sprint Nextel’s Evo handset is being sold at $200.


iPad as audio center for car

This is a killer app for iPad or any other touchpad device in this size. With 3G, this could be a car navigator. Hey AT&T, get ready for the data traffic!

I may want to make external cradle for iPad to connect to car audio and power system, and sell it at apple store.. need some funding for that!!


Already strained, AT&T soon to be coping with iPad | Reuters

Already strained, AT&T soon to be coping with iPad | Reuters.

By Sinead Carew

NEW YORK, April 5 (Reuters) – If you worry that Apple Inc’s (AAPL.O) newiPad will slow down Web surfing on AT&T Inc’s (T.N) mobile network or cause even more dropped cellphone calls, analysts say you should rest easy.

Later this month, Apple will introduce a version of the iPad tablet computer that can surf the Web on the go using AT&T’s third generation (3G) mobile network. The current iPad, which went on sale this weekend and drew big crowds, works only on short range Wi-Fi connections like those found in cafes [ID:nSGE6340DJ].

Some fear that should the 3G version of the iPad prove a blockbuster hit, it could test AT&T’s network, already under severe strain in some markets from heavy iPhone Web usage. AT&T has said it is now investing heavily to upgrade its network.

The theory is that thousands of new iPad users could spend even more time than iPhone users downloading movies, buying books, or just surfing the Web on AT&T’s 3G network.

But several analysts said worries were overblown, even after a strong debut by the first iPad model [ID:nSGE6340DJ]. More than 300,000 of them sold on Saturday, surpassing some forecasts.

“There’s a lot of worry and it makes for good reading to say it will have an impact. But I think not,” said UBS analyst John Hodulik, who expects sales of iPad 3G to be less than half the sales of the first version of the device.

The main reason is money, with Apple charging $630 for the iPad that allows access to both 3G and Wi-Fi. That is $130 more than the first Wi-Fi only model.

And because the iPad is much bigger than a cellphone, consumers will not carry it everywhere they go, unlike iPhone. This means less demand for AT&T. Even its chief executive predicted more Wi-Fi iPad use than 3G use [ID:nN02183567].

NPD analyst Ross Rubin sees iPad buyers using 3G mostly as a back-up when they are traveling out of town.

“It certainly doesn’t fit in your pocket,” Rubin said.

Stifel Nicolaus analyst Christopher King said it was too soon to tell how many people would buy the 3G iPad and how they would use it. But he sees most users sporadically downloading data to the device, much as they use the Kindle e-book reader from

“I don’t think its going to be a big issue for AT&T,” he said.

What is more, Hodulik expects that iPhone sales will begin to tail off over the first half of this year, since consumers who do not already have an iPhone will likely wait for a new Apple phone expected this summer. The result would be fewer new users for AT&T’s network.

Hodulik also pointed to AT&T’s public commitment to increase its capital spending by $2 billion this year in an effort to improve its network performance.

“While this is all going on, AT&T has made a significant increase in the amount it’s investing in its network,” he said. (Reporting by Sinead Carew; editing by Paul Thomasch and Gerald E. McCormick)


I’ve seen many folks complaining about iPhone. In fact most of the complaints are more related to ATT network rather than phone itself. Like dropped call, weak antenna signal, slow internet, etc. This trend will definitely get worse with 3G iPad coming along. People will carry iPad in their backpack or laptop bag and will use 3G network as they use for iPhone. iPad replace ebook market? then cannot rely on wi fi only. Combination of Wimax would be ultimate solution to voice and data dumping on 3G network. Why people doesn’t use data has to suffer poor voice quality with the same price?? – At least two more WiMax handsets coming in 2010 – At least two more WiMax handsets coming in 2010.

SAN JOSE, Calif. — At least two more WiMax handsets are expected to emerge this year, according to the company that designed silicon inside the EVO 4G handset recently announced by Sprint. They will be joined by prototype phones for the Long Term Evolution (LTE) network that will be demonstrated by China Mobile in May, said an executive for Sequans Communications.The handsets represent early versions of a generation of so-called 4G mobile devices. They aim to deliver data rates from 10 to 100 Mbits/second, enabling new video communications and streaming capabilities.

Sprint showed the EVO 4G handset made by Taiwan’s HTC downloading up to 11 Mbits/second of data and uploading an average 2.5 Mbits/s on a production network at the CTIA show in Las Vegas. “I have a cable modem at home that gets about those numbers,” said Craig Miller, vice president of marketing and business development at Sequans which supplied its SQN1210 WiMax baseband chip for the handset.

“We have at least two other handset OEMs in various levels of design” with the WiMax baseband, said Miller. “They are tier one and two recognizable names,” he said.

In mid-March, Sequans announced it was about to sample its first LTE chip as well, a device geared for use on the Time Division Duplex LTE network in development at China Mobile. “Realistically, meaningful network build outs are 18 months out” for the LTE networks, said Miller.

Video communications and streaming will be key applications for the new handsets. The Sprint phone uses front- and back-panel cameras to enable video conferencing and a 720-progressive 4.3-inch screen to play streaming video.

The design challenges ahead include lowering power consumption and cost for the handsets that are expected to use both 4G nets for data and 3G for voice. But Miller argued against integrating 3G and 4G basebands.

“You can build a 3G world phone today support four or five frequency bands, but LTE needs another five or six bands,” Miller said. “The sheer RF complexity gets out of hand because merging that in one chip is enormously complex and you end up paying for bands you will not use,” he said.

The EVO 4G phone, for example, uses the Sequans WiMax baseband for data and a Qualcomm CDMA baseband for voice traffic. Analyst Satish Menon of Forward Concepts criticized the early dual-mode architecture as inefficient, creating a five second delay on the handset for traffic passed between the two nets.

“We’re not handing off a voice call from WiMax to CDMA or back again so you are not suffering,” said Miller. In terms of data, “you can maintain an IP connection across a far larger latency,” he added.


Separate chip for data and voice seems to be a good approach. Sequan is providing data baseband, but so called voice baseband provider will integrate data together as a single chip solution, not in the same Si, but integrating using SIP or TSV. In any approach, that is separate chip or integrated chip, 3G voice will be there for a long time for voice. Cellular is good for voice as it started to support the voice. Meanwhile, IP based communication, such as Wimax, is good for data. The competition for 3G modem will be fierce, and only a few can survive in the end.

Qualcomm’s multi-fold mobile device is the future we keep waiting for — Engadget

Qualcomm’s multi-fold mobile device is the future we keep waiting for — Engadget.

Qualcomm isn’t typically in the business of producing consumer-facing hardware — the company prefers to just build the chips that make your devices go “vroom” — but we’ve come across a patent application that details just such an idea. The multi-fold mobile device can be seen as either a foldable tablet or an expandable cellphone, but in either case its purpose is clearly to act as a hybrid device that performs both roles. With all least two displays on its three panels, this concept will also automatically reconfigure its UI based on a folding configuration sensor, and Qualcomm suggests you might also use it as a widescreen TV display, an alarm clock, a media player, or a web browser. Click past the break for a couple more suggested use diagrams, and feel free to write to Qualcomm with demands that this be put into production pronto. – Asia to take 39% of smartphone market in 2015, says IMS – Asia to take 39% of smartphone market in 2015, says IMS.

LONDON — Annual smartphone shipments in Asia will quadruple by 2015, giving Asia 39 percent of smartphone shipments during 2015, according to market research company IMS Research Ltd. (Wellingborough, England).The growth will be driven by strong demand in China and India and this will present a challenge to the traditional smartphone vendors and an opportunity for competition as well as opening up a large grey market, the firm said.

Overall shipments of smartphones are forecast to increase at a compound annual growth rate of 25.9 percent between 2009 and 2015.

In 2009 Asia was responsible for 60.2 million smartphone shipments, 33 percent of the global figure of 182.4 million. In 2015 IMS expects Asia to see 277.2 million smartphone shipments or 39 percent of a global market size of 710.8 million shipments.

Chris Schreck, IMS analyst, said in a statement that two factors were contributing to the growth in Asia. One are the sizes of the Chinese and Indian markets. The second is that smartphones are coming down in price due to economies of scale and are therefore ceasing to be luxury items and more accessible in those large Asian markets.

“It would be unwise to expect the smartphone market to develop along the same lines as it did in Europe or North America,” said Schreck, in a statement. “Companies like Motorola, who had to change the default search provider from Google to Microsoft on its Android smartphones in China, or Apple, whose iPhone sales in Japan lagged without the inclusion of NFC, have shown the need to adapt products to compete in these markets. Additionally, there is increasing competition from Asian handset vendors like Huawei, ZTE, HTC, and Acer in the Asian smartphone space. Finally, the grey market for mobile handsets is much more established in Asia than in western markets, giving consumers viable alternatives to more conventional handset purchasing methods. These challenges are opening up a booming smartphone market to players who have had trouble competing with entrenched competitors in developed western markets.”

IMS Research defines smartphones as mobile handsets that utilize an open architecture operating system and the company said it expects that a majority of smartphone shipments to Asia will be feature an average selling price of under $120 before subsidies or taxes.


As low end market in China and India grows, more “white label” cell phone will be popular due to cost pressure. In this domain, second tier modem chip companies will get more benefit rather than first tiers. As high end market grows in already developed market such as US, Europe, Korea and Japan, the price pressure from the 2nd tier modem companies will be very strong, thus margin for even high end phone will drop, or even first tier market share will decrease.

Observations: The (good and bad) future of the Internet

Observations: The (good and bad) future of the Internet.

SAN DIEGO—“We know even now that we are at some fundamental limits of what the Internet can handle,” warned University of California, San Diego processor kc claffy [sic capitalization] at the beginning of her talk at theAmerican Association for the Advancement of Science meeting in San Diego. “We have one big expectation—being able to innovate,” she said. “And it is unclear whether we will be able to do that.”

claffy’s warnings are based on the observation that the Internet’s infrastructure is, for the most part, hidden. In the U.S. there are on the order of one hundred Internet service providers that control the fiber lines and the routers that direct traffic throughout the network. Each of these ISPs has agreements with the others to exchange traffic. In essence, these agreements say if you move my bits, I’ll move yours. However, all these agreements are not just independent and unregulated, they’re secret. Proprietary corporate information. This makes it impossible to understand how traffic will get redirected when, say, one path fails. It makes it impossible to understand just how strong the overall system is when something goes wrong. It makes it impossible to map the overall structure of the Internet (something intensely frustrating to claffy, whose job it is to map the overall structure of the Internet). And it also makes it difficult to predict how the Internet will grow.

One thing is for sure, though: The Internet will continue to grow. We just don’t know if the current system for addressing content on the Internet will be able to accommodate this growth. Every location on the Internet—every web site, every user—has associated with it a specific address, called an Internet Protocol (IP) address. The current addressing system—called IPv4—has about four billion possible addresses. The Internet is expected to outgrow this batch of addresses in about two years. For decades researchers have been working on the next generation of addresses—the IPv6 system—which has approximately enough addresses to last until the heat death of the universe. But IPv6 and IPv4 are not compatible, so anyone working with a new IPv6 address would not be able to access Web sites using old IPv4 addresses. “Everyone would have to switch at the same time—Google, Verizon, everyone” claffy told me after her presentation. Yet a massive instantaneous global switchover of the Internet’s entire addressing system is, in short, unlikely.

Irwin Jacobs, the CEO and co-founder of Qualcomm, also spoke regarding the spread of the wireless Internet. He started out with some figures that underscored the estimates of the Internet’s rapid growth. According to Google, he said, half of all Internet connections today come from mobile devices, and the mobile web adoption and growth rates today are eight times what wireline-based adaptation was ten years ago. According to one estimate by Ericsson, the number of wirelessly connected devices worldwide will rise from an estimated 4.6 billion today to 50 billion by 2020. This would be around seven devices for every man, woman and child on the planet. (Jacobs later clarified that he thought these numbers were “ambitious.”)

One well-publicized challenge of mobile 3G networks is dealing with the ever-increasing amounts of video coming through the system. “Video to phones accounts for half the bits now,” he said. One option to reduce strain on 3G networks is expanding the portion of the wireless spectrum used to distribute content. An example of how this could work is FLO TV, a service from Qualcomm that uses the old UHF channel 55 to broadcast over 20 channels to wireless devices. The system is now in place in 68 metropolitan areas, he said.

Whatever happens going forward, the Federal Communications Commission’s upcomingBroadband Access Plan, expected in two weeks, will surely shape the landscape of the Internet over the years to come. Let’s hope it can cope with the growth.
