The device, which measures 3.25 x 2.5 x 0.75 inches, offers 802.11b/g connectivity and can function as an access point, router, or wireless client. It draws power from an included AC adapter, but can also be powered by a notebook's USB port. D-Link supplies a carrying case for the unit and its cables."
A switch on the back of the Wireless Pocket Router/AP is used to select its function. In access-point mode, the device can create a wireless connection wherever a single Ethernet connection is present. The router mode, designed for sharing broadband connections among multiple devices, features an internal DHCP server that automatically assigns IP addresses to connected devices, supports VPN pass-through, and includes firewall capabilities such as Network Address Translation and MAC filtering.
When switched to wireless client mode, the unit enables users to access existing wireless networks from any Ethernet-equipped device.
Note from Bill Drew: Important development. Keep an eye on this new standard.http://search-engines-web.com/ writes "http://focus.ti.com/docs/pr/pressrelease.jhtml?pre lId=sc04181Highlights of the WWiSE Proposal
The technical aspects of the WWiSE proposal mark a significant improvement in the capability of 802.11 implementations. Key features include: Mandatory use of the approved, pre-existing, worldwide 20MHz Wi-Fi channel width, assuring immediate applicability and deployment in all regulatory jurisdictions.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~http://www.reuters.com/printerFriendlyPopup.jhtml? type=technologyNews&storyID=5959406http://www.reuters.com/newsArticle.jhtml?type=tech nologyNews&storyID=5959406
Enhanced MIMO-OFDM technology is key to achieving a maximum data rate of 135 Mbps in the minimum mandatory 2x2 configuration and a single 20MHz channel to keep implementation costs low, while greatly improving upon simple antenna additions or channel bonding schemes.
Rates up to 540 Mbps, accomplished with a 4x4 MIMO structure and 40MHz channel width (where permissible by regulatory bodies), provide a roadmap for future devices and applications.
Mandatory modes affording backwards compatibility and interoperability with existing Wi-Fi devices in the 5 GHz and 2.4 GHz bands to ensure strong support of legacy deployments.
Advanced forward-error-correction coding option to facilitate maximum coverage and range, applicable in all MIMO configurations and channel bandwidths.
A group of technology companies including Texas Instruments Inc. , STMicroelectronics and Broadcom Corp. , on Thursday said they will propose a new wireless networking standard up to 10 times the speed of the current generation.The group says they are submitting a plan for a new standard for a popular short range wireless networking technology known as Wi-Fi -- which is used in airports, hotels and coffee shops to access the Web without wires."
The group, calling itself "WWiSE," said their version of an 802.11n standard would be compatible with the technology currently in use, known by various code names such as 802.11b and 802.11g. Their technology could operate at speeds up to 540 megabits per second.
The group said they planned to submit their proposal to the task force at the Institute of Electrical and Electronics Engineers charged with developing an 802.11n standard.
The group's proposed version of the standard would peak at a speed of 540 Mbps, requiring using a larger communications channel for the signal than most jurisdictions allow. Using the more standard channel size, their 802.11n proposal would peak at 135 Mbps.
They also said they would license their patents necessary to implement their version of 802.11n on a royalty-free basis.
Note from Bill Drew:
I do not know what this has to do with Wi-Fi in libraries but I am approving this submission because it is interesting.
At the Intel Developer Forum on Wednesday Intel announced the company was giving up on the deadlocked Ultrawideband IEEE task group and going it alone with a derivative offering they are calling Wireless USB. This initiative, for them, does everything that Bluetooth does and, effectively means that for PCs Bluetooth is all but dead.====================================http://www.eweek.com/article2/0,1759,1633841,00.as p++++++++++++++++++++++++++++++++++++=
According to industry analysts, some form of UWB (ultra wideband) wireless technology is expected to replace USB (Universal Serial Bus) as a peripheral connector for PCs and could enable a new generation of wireless devices.===============================================http://www.extremetech.com/article2/0,1558,1530522 ,00.asp
With the approval by the feds, the company can ship its XS110 UWB chip set to peripheral vendors, who in turn are expected to release products incorporating the technology by the end of the year, a Freescale executive said. Although Freescale would not disclose its customer list, one of the early uses for the company's "direct-sequence" wireless approach will involve sending video content from a set-top box
Once the standard is completed, the MBOA will resubmit to the IEEE for approval as a fait accompli, executives said. The MBOA specification expects to be able to transfer about 480 Mbits per second, through a spectrum of between 3 to 5 GHz, using OFDM as a physical-layer technology.For Intel, UWB's appeal is simple: eliminating the USB and IEEE 1394 cords that connect consumer and other devices with a PC. "Our job is to kill the wires and we think that UWB is the technology that kills the rat's nest (of wires)," said Pat Gelsinger, chief technology officer of Intel, at the Intel Developer Forum here."
Six wireless providers are set to begin installing equipment for cellar networks, Wi-Fi and Internet telephony in New York City street lamps, traffic lights and other prime real estate this summer under a plan expected to net the city more than $20 million a year, city officials said last week."
T-Mobile USA Inc. and Nextel Communications Inc. are the largest companies taking part in the scheme, originally discussed in February, with Nextel planning to install repeaters capable of carrying any type of wireless service. IDT Business Services LLC is to provide low-income homes with Internet telephony services and equipment, while ClearLinx Network Corp., Crown Castle Solutions Inc. and Dianet Communications LLC will offer the light pole real estate to other carriers.
The use of street lights, street signs and traffic lights could change the way users access wireless services. Currently cellular service providers and wireless ISPs must build powerful base stations on private property, leaving gaps in service, while wireless LAN hot spots are limited to specific locations such as airport lounges and coffee shops. Under the city's plan, access points would be more numerous and would therefore need less power.
3Com Corporation (Nasdaq: COMS) today announced that it has formed strategic alliances with leading gateway vendors to create effortless, plug-and-play solutions for Wi-Fi-certified wireless hotspots worldwide. The strategic alliance vendors' wireless products have passed interoperability testing with 3Com's wireless products to ensure smooth operation of complete hotspot systems. The list of alliance vendors include: Aptilo Networks, IP3 Networks, Nomadix, PatronSoft, Pronto Networks and SolutionInc Limited. The prospect of new wireless hotspots, ideally suited for hotels, airport terminals, train stations, cafes and community centers, will also create new opportunities for system integrators within 3Com's channel partner program."
Through these new wireless alliances, 3Com will be able to provide a wider range of hotspot solutions. Whether a customer is seeking simple authentication for a wireless hotspot or enhanced roaming capabilities between different technologies, such as Wi-Fi and GPRS/UMTS networks, 3Com and the new strategic alliance vendors can provide tested and proven solutions. The new 3Com wireless hotspot program involves these new wireless strategic vendors who will combine their billing and authentication gateways and software with 3Com's wireless access points, Power over Ethernet technology and security devices to build new public wireless LANs (local area networks), better known as "hotspots."

This week, staffers at the Berkeley Public Library will begin putting radio frequency identification (RFID) tags in half of the 500,000 items in their collection.When the tags embedded in copies of "Gone With the Wind" and "Mein Kampf" pass within 18 inches of the library's RFID readers, they'll come to life, revealing a unique identification number specific to each individual copy. The tags will allow readers to do their own checkouts and will liberate librarians from the monotonous -- and sometimes painful -- task of endlessly scanning books.By implementing the system this fall, the Berkeley Public Library will join more than 300 libraries around the world that have already outfitted their books with RFID tags,including theSanta Clara City Library,the Maricopa County Library in Arizona,the University of Nevada, Las Vegas Libraries, the Independence Township library in Michigan and the National University of Singapore Libraries.ven the Vatican Library's vast collection is getting chipped.

University of Michigan researchers have figured out how to build wireless systems even smaller while still retaining range and power efficiency.http://www.sciencedaily.com/releases/2004/07/04072 2085808.htm_____________________________http://www.eecs.umich.edu/RADLAB/bio/sarabandi.dir /saraband_hp.html________________________________"
One obstacle to further shrink small wireless devices has been trying to fit all the components onto one chip but U-M researchers have built a tiny silicon-compatible antenna and frequency resonator that will do just that.
The antenna and resonator are two of the most problematic off-chip components in wireless systems. The two components require large amounts of space off the chip---think of a cell phone antenna extending outward---thus limiting how small a device can be built.
We could have cell phones almost the size of an earpiece," Flynn said. "You could have sensor nodes that are almost invisible, you could just sprinkle them around."
Rather than using a traditional wire antenna, researchers built a slot antenna. In a slot antenna, instead of the metal wire, imagine covering an entire plane with metal, leaving only a slot or groove in the metal bare. Wire surrounds the groove so it's much more effective at radiating electromagnetic waves in a small antenna, Sarabandi said. Because of the antenna's shape, the wireless system does not need a network to match the antenna's frequency to the rest of the electronic device.
