According to Intel Research Berkeley director Eric Brewer, the technology uses “regular Wi-Fi hardware but with modified software.” The new technology is intended for emerging markets, where communications systems remain lacking in villages. Intel plans to carry out a trial of long-range Wi-Fi in Uganda later this year.

The technology requires that signals be transmitted from one antenna to another and not anywhere else. Because it demands perfect alignment of antennas, generating signals is difficult. To address this issue, Intel came out a “steerable” antenna, which uses an electrical signal to guide signals between towers and maintain signal integrity even if physical antennas misalign.

Though somehow similar to WiMax, long-range WiFi antennas are cheaper than WiMax towers, with the former only costing between $700 and $800 apiece whereas the price of the latter would range from $15,000 to $20,000 each.

The said function involves using two channels in the WiFi spectrum to enable higher data transmission, as compared to current WiFi technologies that employ only one channel. Interference, however, is very likely if channel bonding is carried out on the 2.4GHz band, which existing 802.11b/g Wi-Fi gear and digital cordless phones are using. Sans channel bonding, 802.11n can still deliver sustained data rates of 50 Mbps, twice faster than 802.11g but half the maximum speed of 802.11n with channel bonding.

Aside from Intel, several companies like notebook makers Asus, Acer, Gateway and Toshiba, and network equipment vendors Belkin, Buffalo, D-Link and Netgear are ready to ship devices supporting 802.11n standard. Gartner, however, warned against premature adoption of the 802.11n standard. The analyst sees more discussions prior to the ratification of the specification, which might entail further changes and therefore need interoperability testing by the Wi-Fi Alliance. Gartner also fears that 802.11n compliance claims by vendors could mislead customers, who may think that the products “can be made compliant through upgrades.”

The company plans to offer an 802.11 a/b/g/Draft-N PCIe Minicard network adapter card that can work on both the 2.4 GHz and 5.0 GHz spectra. It claimed that the new device can improve performance five-fold and double the wireless range of the earlier 802.11 a/g technologies. The adapter, Intel further stated, also offers an extra hour of battery life as compared to similar products.

Meanwhile, because of the early approval by the IEEE 802.11 working group of Draft 2.0, the 802.11n’s schedule has been changed. Final approval of the draft is due by the end of January, with voting expected by the end of March. The panel plans to work on Draft 3.0 and have it approved by June. With the endorsement of 75 percent of members, the draft could be the basis for the final standard, which is likely to be ratified by October 2008.

The firm originally planned to launch the product along with its new mobile chipset code-named Santa Rosa in the second quarter of 2008. Kedron’s 802.11 n draft-capable version will be named “WiFi Link 4965 AGN” while the non-draft n capable variant will go by the name “WiFi Link 4965 AG”.

Santa Rosa would replace the Napa64 platform and features the ICH8-based mobile 965 chipset code-named Crestline, along with support for FSB800 and the company’s Active Management Technology (AMT). It will house processors with Merom core, including the Core 2 Duo T7100 (1.8 GHz) and the Core 2 Duo T7700 (2.4 GHz). Intel intends to sell T7100 with 2M of L2 cache for $209 and T7700 with 4 MB L2 cache for $530.

The said silicon is due to make an appearance at CES 2007 in Las Vegas. Some analysts believe it will not be an easy road for Qualcomm. At the moment, some 370 technical issues beset Draft 2.0 and IEEE members are not expected to vote on the specifications until March 2007. In addition, the company is facing stiff competition from Intel, which is aggressively marketing its own WiMax equipment.

The silicon, according the company, can extend the range and capacity of wireless networks. DataComm President Ira Brodsky lauded Intel’s move to combine WiMax with WiFi and other wireless technologies, which could benefit users wanting more multimedia content like mobile TV.

The 802.11n standard, which promises better performance than the current WiFi technology, is not likely to be ratified until the first half of 2008.

Gartner analyst Ken Dulaney expressed concerns regarding decisions like that by Intel. He said that a prestandard version might function well in homes where it is deployed as a closed looped technology but could bring interoperability issues in enterprises that have heterogeneous wireless infrastructure.

At that same gathering, Intel officials promoted Ultra Wideband or UWB. Alan Crouch, who heads Intel’s Communications Technology Lab, expects the short range wireless technology to start gaining acceptance in 2007 and become popular in the consumer market. Crouch believes UWB will become a future version of Bluetooth. David Leeper, senior principal engineer for UWB at Intel, claimed UWB “can do video streaming at very low power.” He said downloading a full-length movie through UWB would only take 80 seconds.

Barrett said WiMax “is relatively inexpensive and relatively simple” and therefore “ideal for rural environment where there is limited infrastructure in place.” He made these remarks following his tour of Baramati, a town that Intel adopted under its World Ahead Program. There, he visited a hospital that is using WiMax to connect to the Internet for diagnostic work, a school that is employing new technology-driven learning methods, and farmers in remote villages to assess how information technology can help raise living standards.

The U.S. chipmaker is vigorously promoting WiMax around the globe, spending $1 billion for this campaign. Barrett revealed that there are ongoing trials in some 200 sites worldwide, with about 40 to 50 companies looking to use the technology for commercial purposes.

According to Dadi Perlmutter, who heads Intel’s mobility group, the Santa Rosa package will hit the market in the first half of next year. The company also plans a 2007 release for a new chip using a different architecture from the Core 2 Duo for ultramobile PCs. The chip is expected to eat less power and be considerably smaller than the current mobile designs.

Kedron is expected to be five times better, with data throughputs that are 30 times higher than the 2003 version. The company is now conducting a cooperative testing with major LAN networking suppliers, namely Netgear, D-Link, Linksys and Buffalo, to ensure interoperability of the chipset with other 802.11n products out of the box. The company’s goal is to come out with the first combined Wi-Fi and WiMax radio chipset in two years.

In view of plans by Sprint and Clearwire, Otellini believes WiMax will virtually extend over the whole country, with around 100 million people using the technology. According to the company, no less 200 WiMax trials are under way worlwide.

David Maynor of SecureWorks and independent researcher Jon Ellch, aka Johnny Cache, opted for a video presentation instead of a live demo so as not to provide too much information that could be taken advantage of by cyber criminals. The video showed how easily Maynor was able to remotely control an Apple Computer MacBook Pro using a Dell laptop due to a flaw in the MacBook’s third-party WiFi card. Maynor clarified that the problem is not unique to Mac units and can also affect those running Windows or Linux.
