Japan's largest WiFi maker signs up for latest WiFi technology

this post is created by aisha

  • Japan's largest WiFi equipment manufacturer signs up for Ericsson's WiFi patents
  • Ericsson holds industry strongest patent portfolio in GSM/HSPA/LTE
  • Ericsson also holds essential WiFi patents
Ericsson (NASDAQ:ERIC), the leading patent holder in mobile telecommunications, has signed an agreement to license its patented WiFi technology to Melco Holdings, parent company of Japanese digital equipment manufacturer Buffalo. Buffalo is the largest WiFi manufacturer in Japan with a market share of about 60%.
Ericsson holds the industry's strongest patent portfolio covering technologies like GSM, GPRS, EDGE, WCDMA, HSPA and LTE.
Ericsson's early research on GPRS and HIPERLAN/2 has been the basis of packet technology for later mobile standards such as HSPA, and more recently the latest WiFi standard, IEEE 802.11n.  As a result, Ericsson holds essential patents that are key to developing products in a wide range of mobile technologies, including WiFi.
More and more people use heavy data applications like HD video and gaming wirelessly at home, on their laptops and set top boxes.  Since many homes are connected to fiber optic networks, the bottleneck of data streaming is now in the wireless link, between the fiber and the devices like TV and laptops. The latest high capacity WiFi standard, IEEE 802.11n, provides a solution to this problem by offering significantly greater download speed. It enables several users to simultaneously access heavy data applications with high quality over the same wireless link.

Latest 802.11 Standard Boosts Wi-Fi Power in New Band

The nearly finished IEEE 802.11y could make Wi-Fi more practical over longer distances: Wi-Fi is a compromise. In the unlicensed bands in which it operates, it has to deal with interference from noise sources and other networks, while using very low power, and trying not to make a pest of itself. It's done very well. In the 2.4 GHz band and parts of 5 GHz, the maximum power from the radio is 1 watt (W), and the effective power (EIRP) is 4 W on an omnidirectional antenna. (You can push far more power if you narrow the antenna's beam. And parts of the 5 GHz band restrict radio power below 1 W. I wrote a long rundown of 5 GHz issues back in Jan-2007.)
But there's this lovely new segment of lightly licensed spectrum in the U.S., the 3.65 GHz band. It's a non-exclusive licensed band available only in parts of the country that don't have pre-existing ground-to-satellite or radar uses that overlap. This omits most of the eastern seaboard and most major cities; Seattle is one exception.
The licensing mechanism allows any number of operators to obtain inexpensive licenses, and register the base stations they use by location. If interference arises among base stations, operators are required to work out the problems themselves. I wrote extensively about this band and its rules on 9-May-2008 in profiling Azulstar, formerly a metro-scale Wi-Fi firm, but now a big proponent of WiMax in 3.65 GHz. I also went over the rules for the band on 11-June-2007 when the FCC announced the arrangement.
Several firms offer base station and customer premises equipment for this band now, so close to the 3.5 GHz band more commonly exclusively licensed in Europe and elsewhere. WiMax equipment is available because the 3.65 GHz band can be used with WiMax without any modifications to that protocol, although limited to just 25 MHz of the 50 MHz that the FCC set aside.
Equipment that conforms to a more stringent set of rules about contention and other factors can use the whole 50 MHz, and that's where 802.11y comes in. It's an extension of Wi-Fi to cope with the specific needs--and to open Wi-Fi technology up to 20 W EIRP, a vastly higher power output. This could allow connections over 5 km, the group says.
The Wikipedia entry on 802.11y, clearly written by someone involved with the specification, notes that three specific additions are needed: a tweak to support the way in which the FCC wants contention among competing devices to work; a method for an access point to tell a station (a connecting radio) that it's about to switch its channel or its channel's bandwidth, and the station should do likewise; and a mechanism to handle a base station allowing or revoking permission to use the spectrum without uniquely identifying the user's system or broadcasting its precise GPS-based location.
The standard is near completion and initial approval. I don't have any knowledge about whether any mainstream Wi-Fi equipment makers or metro-scale equipment makers are looking into building 802.11y into their gear.
The fact is that this could be a great technology for the mostly sub-metropolitan markets that 3.65 GHz is available in, although it has the same pain as WiMax: all new gear on the towers and all new adapters for customers.

As I have noticed, an average statistical person carries a mobile phone, a communicator, an iPod or an mp3 player, sometimes a laptop, etc. Have you recognized yourself?! It's absolutely normal, because you are a modern person, your lifestyle is very active!

Now Apple gives you the possibility to exclude some of these gadgets from this list and buy just one that is right for you! An iPod with a touchscreen interface from Apple now gives you more than you even expect from your iPod. The first fans of this Apple iPod are its creators, especially Steve Jobs, the boss of Apple! I am sure that when you take this newest gadget in your hands you will love it too! Anyway, I don't recommend you to take the iPod creator's autographs! You'd better have a look what possibilities does this gadget have!

First of all, the 3.5in widescreen display is really fascinating! It guarantees you the most comfortable revision of films and videos! You will be shocked if you just imagine that you can load 40000 songs! Of course, favorite videos, games or even films can be loaded as well.

But the main novelty of the Apple iPod is that it gives you an incredible possibility to use wireless internet access and a web browser! Its biggest advantage is that the WiFi connection gives you more speed and, as the result, more possibilities than a mobile phone! It is so important and useful for a modern person!

You can take it everywhere - it will distract you in a trip or will be an irreplaceable helper if you need the internet.

Generally, the iPod looks very stylish - no buttons and dials. It is available in five different colors.

There are a lot of different iPods nowadays! So, you should choose the best one for yourself! Why Apple? Because it opens new possibilities and a new level of quality for its clients!

New Qosmic Laptop from Toshiba - Qosmio G40

Toshiba upgrades its series of portable multimedia devices with a new model - Qosmio G40. The new representative of the multimedia laptops is based on the Intel Core 2 Duo T7700 CPU with a 2.4 GHz frequency and the Intel 965 PM Express Chipset. Qosmio G40 has 2 GB RAM (PC2-5300), 400 GB hard disk space on two separate hard drives, an nVidia GeForce 8600M GT with 512 MB memory, a Bluetooth v2.0 EDR module and an adapter for new generation networks from Intel - Wireless WiFi Link 4965 AG.

The Qosmio G40 has a 17'' widescreen WUXGA display with recommended resolution of 1920&times1080 dpi. This display enables video playback in 1080p/1080i format.

This new, third, generation of Toshiba laptops is also equipped with an HD DVD-R drive and 5 Dolby Home Theatre speakers. The developers state that this sound system will transport the viewer directly in the center of the action due to four Harman Kardon speakers (2 for low and 2 for high frequencies) a subwoofer and the upper mentioned Dolby Home Theater technology. The laptop has also an in-built one bit digital sound amplifier, which enables the sound to come out of the speakers without losses in quality. The SPDIF interface enables users to connect an external amplifier to create a 7.1 sound system. Qosmio G40 also supports the High Definition Multimedia Interface (HDMI) allowing connection of other external devices.

To round up a bit, here are some more features:

  • 5 USB ports;
  • a FireWire port;
  • a PC Card type 2;
  • flash memory card reader for any known format;
  • Express Card/54 slot;
  • Gigabit Ethernet;
  • 802.11a/b/g wireless connection possibility;
  • mini-D-Sub15 output;
  • S-Video output;
  • 1.9 megapixel web camera;
  • fingerprint sensor.

The rest of the list will be available at the retailer shop, when the Qosmio G40 will become available.

The gadget is actually already out in Japan, which is not of much wonder, and it costs around $ 3,600, but probably all gamers will not hesitate to invest such money into this powerful gaming tool.
