4G Lte ready to start in 2010, faster then Adsl2
Everything is ready for LTE (Long term evolution) the fourth-generation mobile networks (4G). Many companies announced agreements to 66 networks (22 in 2010) and first Lte products.
The LTE standard is ready for data, while for voice call is in draft. At the same companies announce other news: TD-LTE and LTE Advanced, to hit record Gbps by 2014-2015. The 4G will be the first universal technology for the mobile network. It will also be the first fully IP-based: Lte ends with the era of circuit-switched telephony, designed for mobile calls.
Information, including voice, begin to travel in the form of data packets. A revolution, very expensive: Telia Sonera, at the moment the only Lte operator, have launched it in Stockholm and Oslo, respectively with Ericsson and Huawei. Telia Sonera estimate a cost of 70 million euros to cover another 28 cities in 2010 in Sweden and Norway. Companies must rebuild from scratch the mobile network, with its various systems. Given the costs, it is unthinkable that operators pass to Lte suddenly: they will do so gradually, maintaining at the same time GSM and UMTS / HSPA.
UMTS and / or GSM netowork will remain for some years the only standard supported by most of the cell phones. Ericsson also has multi-standard equipment (it is the first networking vendor in the world, Huawei is the second). Qualcomm has introduced dual-mode chip.
It is urgent to increase the capacity of cells, because the mobile traffic will increase more than sevenfold in the world between 2010 and 2014, according to GSA. The Lte offers greater speed (100 Mbps), lower latency but also lower operating costs: 4G network will work with IP protocol, it needs fewer devices, which are also more advanced and therefore consume less (10 – 20%) also they have a better intelligent traffic management system. A network test made by Ericsson in Stockholm, presented in early May 2010, shows that the performance of Lte are greater than ADSL 2 Plus (20 Mbps), Huawei has shown instead, in Shanghai in late May, some Lte 4g applications: 3D games, high definition IPTV (1080p). From 2011-2012 there will be the first networks TD-LTE (Time Division) while the current is Fd (frequency division, more adapted to the voice). The TD-LTE, shown for its first time at 2010 Shanghai China Mobile Expo, can add up the frequencies in the downlink and uplink , to double the bandwidth.
From late 2009, the industry works at Advanced Lte at 300/100 Mbps to 1.2 Gbps in terms of reduced mobility (as shown by Huawei in March, in the laboratory). Benefits are possible thanks to new functions, such as carriers, and spectrum aggregation (aggregates resources different wireless), the Comp (Coordinated multipoint transmission the user connects to multiple base stations at once) and better Mime download (multiple smart antennas).
From 2015 we will see the first phones cloud, that will do everything via the Internet, will be the first to launch them Huawei and ZTE, while today only Samsung (SCH-r900) and HTC Evo 4G has announced a LTE phone.
4G Lte networks start in Usa around the end of 2010 with Centurytel, Metro PCS, Verizon Wireless, Cox Comms and in Canada with Telus and Bell Canada.

built in air card wireless makes iPad the ultimate portable device
The iPad comes, as you would expect these days with aircard wireless connectivity built in. This is a device that has been designed to be the ultimate portable gadget, and used not only in your own home but when you are out an about too. WiFi technology is everywhere, and the availability of wireless ports increases everyday. Some people think that to truly get the benefit out of the iPad you need 3G, however, I think that for most users they will find that there are more than enough wireless hotspots out there for them to get the most out of devices.
For those times when you are in a WiFi blackspot you can always relished the unconnected time that you have an make use of all of the other features of this ultimate touch screen computer. You can of course use the high definition screen to watch a movie, or listen to your favorite tunes that you have synced up from your main computer using the iPad dock. If you want some time to relax and are in one of those rare moments without a wireless connection you could always read a book on the beautiful eReading application. When you are back and connected you can download music, books and films straight to your device in just a couple of clicks, or more accurately touches.
Due to Apple’s early locking down of the iPhone, many of the fantastic applications utilized wireless connectivity to talk to other devices, and this trend is set to continue with the iPad and the new applications being developed specifically for this device. We expect that there will be far more business user centric applications and this will mean that people would want to hook up their iPad using a wireless connection to presentation devices, printers and even to hook in to bespoke machinery such as in the medical world.
There are a number of fantastic iPad accessories being released along with the iPad, but there are a lot more coming on to the market. As wireless becomes more common and more useful, expect to see a lot more peripherals supporting this kind of connection. When you combine the ultimate usability of the iPad, along with both the native and third party applications you can get for it and you connect it to a wireless network and ultimately the Internet you can see that it really is the future of wireless computing.

Internet on the aircraft with your air cards
Some of the major U.S. airlines are equipping their airplanes with the access point capable of supporting the Gogo system, developed by Aircell, to allow passengers Internet inflight access with their laptop and air cards . The service has not only attracted the attention of big companies specialized in the business traffic as Delta, United, Virgin America,American Airlines but even AirTran, low-cost carrier overseas, has installed Gogo internet system on its Boeing 737 and 717.
Delta has already deployed the service on around half of its domestic fleet (150 aircraft).
When aircraft reach the minimum quota of 10 thousand feet, passenger may activate their laptop and air cards and check the signal called gogoinflight. Inside the portal Gogo Mobile you will simply enter your login credentials to start surfing on Internet. At present, rates of use vary between 7.95 and $ 12.95, it depends on the duration of the flight and the type of device. The download speed can vary between 266Kbps and 1.4 Mbps, while upload range is more limited: around 250-300kbps.
Internet on aircraft cost to airlines, without difference between type of airplane, around 100 thousand dollars. Arianne Venus, spokeswoman for Aircell, said that the orders orders exceed their expectations. The changes needed on the aircraft include the installation of three antennas fixed on the outside of the fuselage through which aircraft can make contact with the national air-to-ground net (ATG) operated by Aircell, which will soon consist of 500 towers able to emit a signal up to 350 miles away.
The same Aircell CEO Jack Blumenstein, was expressed on the success of Gogo but that the devices ideal for use will not be the laptops with air cards, whose autonomy is limited when you consider the length of flights coast to coast, but with the smartphone chip integrated WiFi, more manageable. “When two summers ago we began to set up our network – explains Blumestein – no smartphone with wireless technology was available. Now 90% of mobile devices out in the next five years will include a WiFi chip “.
Remains to be resolved the problem of security. A test conducted last summer by SNOsoft Research Team has shown a vulnerability in the transmission of data between the device and the aircraft access point: the connection is found not encrypted so it is possible that the vortex of data that runs on the director can be intercepted from other passengers motivated by dubious intent.

New Fonera 2.0n wireless router now supports usb 3g air cards
After months of fervent planning and waiting by the increasing number of Foneros, the community dedicated to wireless connectivity created by the Spanish social FON gives now a welcome to the new entry of La Fonera 2.0,n the new router’s wireless, enhanced by increasingly broad compatibility with many web based services and with usb 3g air cards support. In the meantime, there has been considerable interest in the agreement between WeFi Fring and aiming to make the search for a hotspot to connect to open a real snap. All this, in the name of social-mobile connectivity.
Waiting to know if its use IS IMMUNE OR NOT from a legal standpoint, the new spanish router arrives on the European market at a price decidedly competitive: 59 euros for the new router enriched by a new firmware (2.2.5.0 flipper enduser) and new, interesting feature. The most interesting is undoubtedly the addition of support for popular USB air cards offering connectivity with 3G: With this feature you can then connect the router to air cards to spread via wireless connectivity to other devices.
Equipped with a LAN access more than in previous La Fonera 2.0 supports the 802.11 b/g/n wireless protocol provides full native compatibility with the most popular social networking services and file sharing: from YouTube to Facebook, from Flickr to Picasa, via BitTorrent , RapidShare and MegaUpload, not forgetting the chance to share with other computer scanners and printers. But FON is not only this: the feature that has most contributed the rise of Spanish in all likelihood is the revolutionary idea of shared social network.
La Fonera shares in two parts connectivity provided by the ISP: from one side the encrypted part (for the premises of the user), other side than one making available to the community, which may benefit from free (for registered service) or payment. In the latter case, the revenue generated will be divided equally between those who provides the bandwidth and the Spanish company.
Still in the field of wireless connectivity, it is expected the users would benefit with the partnership signed between Fring, one of the most widely used multi-platform IM client and WeFi service that maps all free hotspots in the area. Marriage between the two gave birth to a free plugin for the client Fring allows you to search for access points using (if any) the internal GPS to your mobile device or through the inclusion of its position on the map. At the time, according to Fring’s website, the plugin is only available for all devices with Symbian OS or Windows Mobile: It is not known at this time whether this is an update to the ever-growing user community with iPhone.
According to WeFi, there are already over 20 million hotspots accessible free of charge by the community of users using Fring, a number that should not be underestimated, since in many countries, mobile telephone providers do not seem to provide cheap solutions in the field of connectivity to the Web using the 3G network both for mobile and for laptop with air cards. “WeFi represents an exciting new opportunity for our selection of add-ons made for Fring, because it allows us to locate and access thousands of free hotspots all over the world in a very simple way, making the mobile web experience even more attractive for those who prefer the quality of the WiFi at no cost”, said Avi Shechter, CEO of Fring.

How to improve wireless signal of your air cards
Sometimes it happens. In your home you find an open wireless networking, you prepare to navigate freely but the signal for your air cards is too weak. You dock in the wireless line but fail even to get the simple page of google. We need a little more power.
You can get off the street, but it is inconvenient, or go and buy an usb extension of a few meters to hang on your wireless air cards , put it out the window and see if the signal is strong enough, or do this simple thing: open the fridge , take out a can of cola or beer , drink it, and then follow the video below. Take the tin and with a pair of scissors cut the top, the one where there is the tongue. Now clean, but be careful to cut yourself! To avoid trouble in this way put the tape around the edge opened. Practice a hole at the bottom as shown in the video and now you are ready. Just put your usb air cards inside the can, which should amplify a few db in the signal reception of your aircard. Your signal is now strong enough.
