Constantly Connected: Beyond WiFi and Bluetooth.Constantly Connected: Beyond WiFi and Bluetooth
Technology leaders are pushing the envelope of wireless connectivity well beyond WiFi and Bluetooth. The speed and availability of wireless that we enjoy today promises to be bigger and better as the next generation of standards becomes more pervasive: think constant connectivity at significantly higher speeds and lower costs. Here's a quick overview of emerging wireless standards to watch:
Intel's latest wireless technology, WiMax, delivers wireless broadband High-speed wireless transmission of data. What is "high" speed is always a changing number. Wireless systems are typically slower than land-based, wireline networks. In the past, wireless broadband started at 250 Kbps, whereas land-based broadband was generally considered to start at T1 connections ranging from one to 10 miles, compared to the 150-foot range of WiFi connections available in many offices and public hotspots today. WiMax is being positioned as a complement to WiFi and an alternative to DSL DSL

Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary and cable Internet Internet access via the cable companies. There are two kinds of service. One uses a cable modem to connect to a computer, and the other uses an enhanced cable box that provides Internet access directly at the TV. access in homes today. Although it will be a couple of years before the benefits of WiMax are evident to the mobile user, Intel and major telecom providers are pushing the technology into rural areas where the current hard-wired broadband systems don't reach. If Intel and partners are successful in implementing the WiMax vision, mobile professionals will be able to retire their hotspot finders, because connections will be available everywhere we go. On another note, because WiMax reduces the need for wired provider networks, the wireless broadband market will open up to startups and more intense competition among the major providers, which equates to more options and lower bills for our at-home Internet access See how to access the Internet. .
Mobile-Fi, AKA Mobile Broadband Wireless Access (MBWA MBWA Mobile Broadband Wireless Access (IEEE 802.20)
MBWA Management By Walking Around ), is a similar standard to WiMax, and it seems to be losing the race for industry acceptance. This is probably due to the massive market power of Intel and Alcatel vs. Mobile-Fi's smaller primary backers, Flarion Technologies and Navini Networks. Mobile-Fi differs from WiMax in that it can deliver broadband Internet access Broadband Internet access, often shortened to just "broadband", is high speed Internet access—typically contrasted with dial-up access over modem.
Dial-up modems are generally only capable of a maximum bitrate of 56 kbit/s (kilobits per second) and require the full use of a to users traveling at speeds of up to 155 miles per hour. Mobile-Fi may be perfect for train commuters, but it may never make it to the mainstream because products will not be offered until after WiMax becomes broadly available in the consumer market.
Ultra Wideband (802.15.3a)
Ultra Wideband, often referred to as UWB (Ultra-WideBand) A wireless technology that uses less power and provides higher speed than 802.11 Wi-Fi networks or first-generation Bluetooth products. UWB is expected to provide wireless video transmission for home theater systems, cable TV, auto safety and , allows you to transfer data wirelessly with a radio connection, much like Bluetooth but hundreds of times faster. Ultra Wideband eliminates the need for USB USB

Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. and Firewire cables between computers and peripherals. Some of the more exciting uses: click a button on your camera and picture files zoom to the desktop, or hit a key on the computer and a DVD DVD: see digital versatile disc.

Type of optical disc. The DVD represents the second generation of compact-disc (CD) technology. movie displays on your flat-screen TV. UWB products, including phones, cameras, and TVs, should begin hitting the shelves in late 2005. UWB and Bluetooth have recently teamed up to create better cooperation and development for both standards, which can only mean good things for consumers who like to operate without wires.
ZigBee is mainly geared towards home and building owners who want to build a network to control household appliances, power, and security. It's a low-power usage technology that operates on the same radio frequency as Bluetooth, microwaves, and cordless phones. The ZigBee Alliance, lead by Mitsubishi Electric and Motorola, has been working on the standard for several years. According to ABI Abi (ā`bī) [short for Abijah], in the Bible, King Hezekiah's mother.
(Application Binary Interface) A specification for a specific hardware platform combined with the operating system. Research, more than a million Zigbee-enabled devices will ship in 2005, and more than 60 million will ship the following year.
