But reliable, portable monitoring devices are only one element in the equation. The second is the network across which the data they collect can be sent—and here two new technologies are particularly relevant third-generation (3G) mobile telephony and a wireless network protocol known formally as 802.11 and colloquially as Wi-Fi. 

Improvements in videoconferencing should increase the quality of the received picture, and permit higher quality images over lower bandwidth. Additionally, improvements in mobile or wireless networks (e.g., EDGE network, EVDO... 

The instrument is controlled by an IBM Think Pad laptop computer via a wireless network, utilizing ASD s proprietary software package. For this study, reference standard readings were collected before each sample reading to ensure consistent equipment function and to establish atmospheric conditions. 

In recent years, research into wireless networking has been dominated by the perceived need for high bandwidth access to data intensive files with extensive graphical, video and audio content. Bluetooth has been heralded as the low-power wireless standard of the future, but it is very much a high-bandwidth technology, designed to integrate portable devices into this communications infrastructure, and is relatively power...

ZigBee May become the ultimate wireless control system for home and office lighting and entertainment systems. The ZigBee Alliance is an association of companies working together to enable reliable, cost-effective, low-power, wirelessly networked monitoring and control products based on an open global standard, 802.15.4 entertainment systems. 

Wireless networks afford health care professionals greater flexibility to render patient care because they allow care to be moved to patients instead of having to bring patients to the care. PDAs are used to interface with wireless networks, which makes delivery of...

One of the most fascinating cabling technologies today—and, actually, it s one that doesn t really use cable—is wireless. Wireless networks offer the ability to extend a LAN without the use of traditional cabling methods. Wireless transmissions are made through the air by infrared light, laser light, narrow-band radio, microwave, or spread-spectrum radio. 

Information systems—by which we mean an interrelated suite of communication and computation technologies—are the third infrastructure we consider. In addition to the spread of information services across the population, the other important development during the twentieth century was the advent of wireless information systems. First, the country was hardwired for telephony, and then systems of wireless telephony were built. First, the internet was built on a hardwired infrastructure. Now increasingly it is based on wireless networks. These trends point to a future in which information continues to be untethered from location. 

Another recent development essential to increased communications is wireless networking. Wireless networks are appearing in homes and businesses, and as well as restaurants, airports, movie theaters, and other locations that offer public access to wireless networks—some for a charge, others for free. Data on the initial proliferation of public Wi-Fi (wireless) networks and users are shown in Fig. 3-9. 

Wireless network technology is appearing in vehicles. Wireless networks are being used to integrate communications with a driver s cellular telephone.
