HP: Intel chip flaw to delay products

SANFRANCISCO: Hewlett-Packard said that the availability of certain machines will be "impacted" by a chip- design flaw disclosed by Intel Corp. and that it will delay a product presentation scheduled for next week in San Francisco.

"We are postponing the business notebooks briefing on Feb. 10 as the availability of HP products will be impacted" by the flaw outlined by Intel, according to a statement sent to reporters yesterday by Edelman Public Relations Worldwide.

Intel, the world's largest maker of semiconductors, said on Jan. 31 that it will incur $1 billion in missed sales and higher cost to fix the design flaw. The error also is affecting personal-computer makers including Samsung Electronics Co., which said it will offer refunds on some PCs, and NEC Corp., which said it may push back the release of four new models.

The fault is in a support chip, or chipset, for Intel's latest processor model called Sandy Bridge, unveiled this month in a bid to improve PC graphics and repel a challenge by Advanced Micro Devices Inc.

HP, the world's largest maker of PCs, sells many computers that use chips other than Sandy Bridge, said Marlene Somsak, a spokeswoman for Palo Alto, California based HP.

"HP has the broadest lineup of PCs in the industry and there are many HP choices using a wide variety of processors," Somsak said yesterday.

HP climbed 83 cents to $46.52 in New York Stock Exchange composite trading yesterday. It declined 18 percent last year.

XPS, Alienware

Dell Inc. spokesman David Frink said in an e-mailed statement that the Intel flaw affects four Dell products sold under its XPS, Vostro, and Alienware brands.

"We're committed to addressing this with customers who have already purchased one of the four products, will work directly with them and provide further detail as it becomes available," Frink said.

Computers that use the potentially faulty chips have been sold since Jan. 9, and Intel said it's corrected the flaw and begun manufacturing a new version of the chip that will resolve the issue.

Intel said it expects to begin delivering an updated version of Sandy Bridge's chipset, called Cougar Point, to customers in late February and be at full production in April. The company has shipped about 8 million of the Cougar Point chips to customers that will have to be replaced, Chief Financial Officer Stacy Smith said on a Jan. 31 conference call.

HP had planned to discuss the notebook computers, aimed at business customers, with journalists next week, before officially unveiling them to the public on Feb. 23, according to an earlier e-mail from Edelman.

Mobile Number Portability(MNP)

 General Overview
MNP is implemented in different ways across the globe. The international and European standard is for a customer wishing to port his/her number to contact the new provider (Recipient) who will then arrange necessary process with the old provider (Donor). This is also known as 'Recipient-Led' porting. The UK is the only country to not implement a Recipient-Led system, where a customer wishing to port his/her number is required to contact the Donor to obtain a Porting Authorisation Code (PAC) which he/she then has to give to the Recipient. Once having received the PAC the Recipient continues the port process by contacting the Donor. This form of porting is also known as 'Donor-Led' and has been criticised by some industry analysts as being inefficient. It has also been observed that it may act as a customer deterrent as well as allowing the Donor an opportunity of 'winning-back' the customer. This might lead to distortion of competition, especially in the markets with new entrants that are yet to achieve scalability of operation.

Technical details

A significant technical aspect of MNP (Mobile Number Portability) is related to the routing of calls or mobile messages (SMS, MMS) to a number once it has been ported. There are various flavours of call routing implementation across the globe but the international and European best practice is via the use of a central database (CDB) of ported numbers. Network operator makes copies of CDB and queries it to find out which network to send a call to. This is also known as All Call Query (ACQ) and is highly efficient and scalable. Majority of the established and upcoming MNP systems across the world are based on this ACQ/CDB method of call routing. One of the very few countries to not use ACQ/CDB is the UK where calls to a number once it has been ported are still routed via the Donor network. This is also known as 'Indirect Routing' and is highly inefficient as it is wasteful of transmission and switching capacity. Because of its Donor dependent nature, Indirect Routing also means that if the Donor network develops a fault or goes out of business, the customers who have ported out of that network will lose incoming calls to their numbers. The UK telecoms regulator Ofcom completed its extended review of the UK MNP process on 29 November 2007 and mandated that ACQ/CDB be implemented for mobile to mobile ported calls by no later than 1 September 2009[dated info], and for all other (fixed and mobile) ported calls by no later than 31 December 2012.
Prior to March 2008 it took a minimum of 5 working days to port a number in the UK compared to 2 hours only in USA, as low as 20 minutes in the Republic of Ireland, 3 minutes in Australia and even a matter of seconds in New Zealand. On 17 July 2007, Ofcom released its conclusions from the review of UK MNP and mandated reduction of porting time to 2 working days with effect from 1 April 2008. On 29 November 2007, Ofcom completed its consultation on further reduction to porting time to 2 hours along with recipient led porting and mandated that near-instant (no more than 2 hours) recipient led porting be implemented by no later than 1 September 2009.
In a decentralised model of MNP, a FNR (Flexible Number Register) may be used to manage a database of ported out/ported in numbers for call routing.

Number Lookup Services

Service providers and carriers who route messages and voice calls to MNP-enabled countries might use HLR query services to find out the correct network of a mobile phone number. A number of such services exist, which query the operator's home location register (HLR) over the SS7 signalling network in order to determine the current network of a specified mobile phone number prior to attempted routing of messaging or voice traffic.

>>switch to TATA docomo
>>switch to vodafone
>>switch to aircel---
         To switch, call 98020 98020 (exclusive MNP helpline for non-Aircel users) or visit your            nearest Aircel Store.
>>switch to idea
       
Procedure to shift your existing number to Idea cellular:
  • First you will need to generate a Unique Porting Code (UPC) from your mobile number. To generate this code you just need to send SMS as “PORT” (space) mobile number to 1900.
  • After sending sms, visit your nearest My Idea store, submit mandatory documents and fill the Customer Application Form and Port-in form, pay Port-in fee of Rs. 37 (includes Rs. 19 as Porting charge + Rs.18 as New Sim card charge), get a new Idea SIM and request for port-in.
  • Now, new SIM purchased will be activated within 7 working days. Activation date and time will be informed to you through SMS. As soon as you receive sms, you need to insert the Idea SIM into your phone and enjoy the services of Idea cellular.
For further assistance, you can also call 98120 12345 which is the customer care number of Idea cellular.
>>switch to BSNL 
Procedure for MNP Port-in request at BSNL CSCs:
1. Port-in customer will take UPC by sending SMS PORT followed by 10 Digit Mobile Number to 1900.
2. Port-in customer will submit CAF (application form) and MNP form with UPC at CSC.
3. Customer should be asked for an alternative number and desired FRC (2G/3G etc.) and record on BSNL/Porting CAF for future use.
4. Customer will be given a virgin SIM. On this virgin SIM, his number will be created afterwards. It is to be informed to the customer that after 72-96 hours or on getting SMS he/she may insert the SIM in the mobile and dial ‘123’ to activate BSNL services.
5. CCN person will complete the required entries in Fx GUI, mention type of FRC in the prescribed field and fire order for creation of new port-in number using MSISDN, IMSI, UPC etc.
6. SIM will be created after minimum 72 hours (assuming it is approved by the port-out operator) and maximum 96 hours.
8.Before activation of the BSNL services, there will be an interruption/ transit time of around 2 hours i.e. subscriber will not be getting services of any operator.

Meet first 4G wireless tablets, phones

4G.jpg
This year, the big national wireless carriers will be racing to stake their claims in the new frontier of service: ultra-fast data access - for smart phones and laptops as well as for gadgets like tablets.
LAS VEGAS: This year, the big national wireless carriers will be racing to stake their claims in the new frontier of service: ultra-fast data access — for smart phones and laptops as well as for gadgets like tablets.

The companies are boosting their wireless data speeds and revving up the marketing hype. They're moving away from talking about call quality and coverage, and focusing on data speeds: megabits in place of minutes. For consumers, there are benefits in the form of faster service and cooler gadgets. Yet some of the marketing campaigns seem designed to confuse consumers about the gadgets' speed.

At the International Consumer Electronics Show in Las Vegas this week, Verizon Wireless revealed the 10 gadgets with built-in access to its new high-speed wireless data network, including smart phones, tablet and laptops. Some are to launch as early as March.

Along with Sprint Nextel Corp.'s subsidiary Clearwire Corp., Verizon is at the forefront of the move to a new network technology, designed to relay data rather than calls. Verizon's fourth-generation, or "4G" network, went live for laptop modems in last month.

The new wireless network is the nation's fastest. Verizon is hoping to cash in on that advantage by selling tablets and smart phones that devour data.

One of the devices, Motorola Mobility Inc's Xoom tablet, will come with a 10.1-inch screen and two cameras: one for video chatting, the other for high-definition videos. The Xoom will begin selling by March. Initially, it will work with Verizon's 3G network but will be upgradeable to work on the speedier 4G network.

Motorola's Droid Bionic smartphone will also have two cameras, to help with videoconferencing, a data-hungry task. It will be one of the first phones with a so-called "dual-core processor" that will roughly double its computing capacity. That should help with video processing.

LG Electronics Inc, Samsung Electronics Co and HTC Corp are bringing out similar phones for the network. Hewlett-Packard Co is adding 4G capability to a laptop and a netbook.

There will also be two "mobile hotspot" devices for the network: small battery-powered bricks that act as Wi-Fi access points, connecting Wi-Fi-equipped computers to the 4G network.

Verizon didn't reveal what the new devices or wireless plans will cost.

Verizon's size — by number of subscribers, it's the largest U.S. wireless carrier — and the quality of its network are helping it gain traction with manufacturers.

"By deciding to go early and go first to (4G), we sent a signal to the entire consumer electronics market that this technology would develop very quickly," said Lowell McAdam, Verizon's president and chief operating officer, in a keynote address at the trade show Thursday.

There's speculation that Verizon will get to sell a version of Apple Inc's iPhone this year. That would break AT&T Inc's exclusive hold on the most popular smart phone. But there was no talk of an iPhone from Verizon at Thursday's events.

With or without the iPhone, Verizon's new network is pressuring its competitors to step up their offerings. AT&T Inc on Wednesday said it's on track to launch its own 4G network this summer. Also, it said it will start calling its current 3G network "4G," since it's been upgraded to be capable of nearly 4G speeds.

T-Mobile USA said that it will upgrade its 3G network to double the possible download speeds in two-thirds of its coverage area. It started calling the network "4G" in ads last fall. It, too, revealed two tablets for its network, to launch later this year.

Sprint and Clearwire have chosen a slightly different route to 4G. They've picked a 4G technology called WiMax that was ready before Long Term Evolution, or LTE, which Verizon is using.

Now, however, WiMax looks set to be a niche technology, while the rest of the industry adopts LTE. That will hamper Sprint's efforts to get competitive devices for the network. Still, it was able to launch its first 4G phone last summer, ahead of the competition. Recently, it announced it would be the first to carry a 4G tablet computer from Research In Motion Ltd, the maker of the BlackBerry, some time this summer.

The most distinctive feature of 4G technologies like LTE and WiMax is that they're designed to carry data rather than phone calls. That makes them more efficient at serving today's smartphones, tablets and other gadgets that need data access on the go. It also makes the networks cheaper to build out and manage.

They're faster than today's 3G networks, though not by much, which makes T-Mobile and AT&T feel justified in calling their upgraded 3G networks "4G." After all, they say, speed is what really matters to users.

Aside from the bump in speed, the main reason the LTE buildouts of Verizon Wireless and AT&T significant is that they add fresh spectrum to the nation's wireless networks. That means more capacity for the growing number of mobile gadgets.

Also, both companies are using spectrum that was previously used for UHF TV channels, a prime piece of the airwaves. It can cover wide areas easily and penetrate deep into buildings. (Clearwire's WiMax network uses a frequency that has shorter range and more difficulty penetrating buildings.)

Future upgrades can further boost the speed of wireless networks. But at some point, they will run out of room for improvement. There's a theoretical limit for how much information a certain slice of the airwaves can carry. When that happens, there will still be two ways to add capacity to wireless broadband.

The government can assign more spectrum, perhaps by taking it from TV stations. But spectrum, too, will run out. The carriers can add more cell towers, but that's expensive and difficult. They can't put cell towers everywhere they'd like.

Given these limiting factors, wireless broadband isn't likely to ever replace wireline connections for home broadband, except possibly in rural areas where it's expensive to draw cables for high-speed connections to homes.

The US is at the forefront in the international race to LTE. Verizon's buildout is the world's largest. The US was faster than most other countries in taking back airwaves from TV stations and selling it off for wireless broadband.

Another reason Verizon has been aggressive about LTE is that its 3G network uses a technology that isn't upgradable to higher speeds as AT&T's and T-Mobile's are. That's left it with a burning need for the next network technology.

Verizon Wireless is a joint venture of Verizon Communications Inc and Vodafone Group PLC of Britain. Motorola Mobility Inc was formed this week as Motorola Inc split into two parts. The Mobility consists of the cell phone business.

Twitter sets record on new year in Japan

Twitter
TOKYO: A flood of Japanese Tweets sent as the New Year arrived in Tokyo boosted global traffic within the network to a record 6,939 tweets per second (TPS), the microblogging site has reported.

The figure more than doubles the previous record of 3,283 TPS, set during Japan's surprise victory over Denmark in last summer's World Cup in South Africa, it said.

"Just four seconds after midnight in Japan on January 1st, Twitterers set an all-time record in the number of Tweets sent per second," Twitter said in a blog posted Thursday.

"At that moment, the world sent a staggering 6,939 TPS wishing friends and followers a fond 'Akemashite omedetou gozaimasu' ('Happy New Year!')."

Twitter said that in Japan, with a population of over 127 million, "mobile networks have been known to crash under the strain of this collective cheer. This year, on New Year's Eve, many people turned to Twitter to celebrate."

Twitter said that on New Year's Eve, "we saw epic Tweet activity around the world as people in each time zone inaugurated 2011".

In the United States, "the East coast time zone alone almost amassed the same amount of Tweets at its peak of 3,000 TPS as the entire world did during the peak moment of the World Cup."

Created in 2006 to exchange messages of no more than 140 characters, Twitter had 175 million registered users as of November 1 and transmitted 25 billion "Tweets" last year. About 95 million messages a day are sent over the site.
