The first generation of High Speed Packet Access mobile services increased download speeds to mobile phones. Now carriers are also launching HSPA services, also known as Turbo-3G, with faster upload speeds, making the mobile office even more of a reality.On Thursday, AT&amp;T Wireless unveiled two new LaptopConnected HSUPA (High-Speed Uplink Packet Access) data cards for its wireless broadband customers.Another carrier that has upgraded its network and recently launched a service is 3 Sweden.&quot;We are mainly talking to professional users. It&#39;s a really good service for people that need to send large files,&quot; said Camilla B&#252;low.It charges a flat monthly fee of 299 Swedish kronor ($46) for the service, aptly named Pro.AT&amp;T Wireless and 3 Sweden are not the only operators speeding up their networks. Around 50 carriers currently support HSUPA, according to the latest figures from GSM Association, a group representing network operators.&quot;Moving to HSUPA is a logical progression, and it doesn&#39;t take a substantial investment to upgrade,&quot; said David Pringle, spokesman for the GSM Association.Heavy e-mail users aren&#39;t the only ones who have a lot to gain from faster upload speeds. In a world where consumers create more of their own content and make phone calls from the PC, and where the move to delivering software as a service is gaining momentum, faster upload speeds are becoming increasingly important.&quot;We are doing a lot of work around virtual desktops, and faster network speeds in both directions would improve the mobile user experience,&quot; said Peter S&#246;derholm, field systems engineering manager at Citrix Systems Nordic.The first iteration of HSUPA supports theoretical data rates of up to 1.4Mbps. In the real world that means around 1Mbps -- three to four times faster than existing networks. Next year the speed will increase to up to 5.76Mbps, and carriers are getting ready for that too.&quot;Our network is ready for that speed, but we haven&#39;t said when we are going to upgrade,&quot; said B&#252;low.For the technology to become useful, users must have compatible modems and phones. Modems are becoming more common, but mobile phones are still scarce. HSUPA products launched at last week&#39;s Mobile World Congress included Sony Ericsson&#39;s Xperia X1 and Toshiba&#39;s Port&#233;g&#233; G810.&quot;The phones are a bit behind,&quot; B&#252;low concluded.

(InfoWorld) - NTT DoCoMo has embarked on a month-long experiment of a Super 3G (third-generation) cellular system. The indoor experiment will test data transmission speed and NTT DoCoMo hopes to hit a downlink speed of 300Mbps, it said Friday. First trails will involve the use of a single antenna on both the transmitter and receiver and then the use of up to four multiple-input multiple-output (MIMO) antennas. The tests will also look at the speed with which communications can be handed from one base station to another. Super 3G, which is also known by the acronym LTE (long-term evolution), uses the same radio spectrum band as current 3G services, but that's one of the few similarities. Super 3G allows for a number of different bandwidth channels and uses different modulation systems to transmit the data. It is envisaged to eventually allow data links at 80Mbps to the network and 300Mbps from the network. The company, which is Japan's largest cellular carrier, has been working on Super 3G for some time and anticipates introducing the technology in Japan sometime around 2009 as a stepping stone between current so-called 3.5G technology and future 4G (fourth-generation) systems. NTT DoCoMo has also been aggressively pursuing 4G system development. In experiments conducted in late December last year the carrier came close to hitting aÂ 5Gbps data transmission speedÂ from an experimental 4G system to a receiver moving at 10 kilometers per hour.

It&#39;s easy to be wowed by Japan&#39;s mobile communications infrastructure. &quot;Next-generation&quot; 3G coverage is now so ubiquitous that carriers have already stopped launching 2G phones; an impressive array of attractive handsets offer free digital TV; phones can be used to pay for goods and train rides, thanks to embedded contactless smart cards; and on the mobile information superhighway data whizzes along at 3.6Mbps. But watch out for the off-ramps.While Japan has led the world with many of the services offered to consumers, in some ways the mobile ecosystem here is downright backward as I found out last weekend when I tried to buy a new phone. A broken handset necessitated a new model and this is where my story begins.In Japan, phones are sold by carriers and not the phone makers. Companies like Fujitsu, NEC, Sony Ericsson, and a few foreign vendors including Nokia, Samsung, and LG sell their phones in the thousands to carriers. This gives carriers the ability to pretty much dictate to the phone maker what software needs to be installed.This model is one of the reasons that mobile Internet services like I-mode took off here so quickly. There was no chicken-and-egg situation with phone makers and users waiting for each other to take the plunge. NTT DoCoMo decided I-mode would be in new phones and so it was.But this model has a downside. Phones are so tightly customized to each carrier that it&#39;s not practical to keep the same handset when switching carriers, and if you see a phone you like you can only buy it if it&#39;s offered by your carrier.Back to my story. The new phone was looking quite expensive so I decided to switch carriers and take advantage of a free phone on a competitor network. Japan launched number portability a year ago, so I could make the jump without losing my cell-phone number. I&#39;d still have the hassle of a new e-mail address, but it appeared a small price to pay.Before long I had a new phone in my hands, but my phone numbers remained locked in the old handset. The new carrier didn&#39;t have a cable to hook up to my old phone so they couldn&#39;t transfer the address book and it wasn&#39;t possible to beam it between the phones. While my old carrier was gung-ho on Bluetooth, my new carrier wasn&#39;t so enthusiastic, so the new phone had no support. Similarly, while the new phone offered infrared, the old phone didn&#39;t. Heavy customization strikes again.Back home I fired up my PC and managed to get my address book from the old phone into the computer. Getting it to the new phone via a memory card seemed like an easy task ... but no! The VCard file wasn&#39;t being properly read by the new phone. Carriers, it was explained to me when I called the help line, often used custom fields in their VCards so there were sometimes problems. So much for a common standard.I won&#39;t bore you with the technicalities of how I eventually got my address book into my new phone, but suffice to say this story has a happy ending. I&#39;m now back in cruise control, enjoying all the attractions the mobile superhighway has to offer.The number portability system that enabled me to keep my phone number is coincidentally one-year-old this week. About 3 percent of users in Japan -- roughly 3.7 million people -- have made use of the system during its first year -- far less than the industry predicted, or feared.One thing that&#39;s said to be stopping users from switching is the inability to keep their e-mail addresses. While carriers fussed over the details of keeping numbers, they forgot, or perhaps ignored, the need to carry e-mail addresses between carriers. In other countries this wouldn&#39;t be a big deal because most messaging is done via SMS, which relies on phone numbers, but in Japan the advanced stage of the market has again caused hassle for consumers.
