An Investigation of the Impact of Wireless Networks on Business
Wireless technologies represent a rapidly emerging area of growth and importance for providing access to the networks for the workplace community. Employees, clients, and customers increasingly want service and network access from various places inside and outside the company. There has been significant interest lately for all businesses to set up mobile computing workplaces for their employees and also mobile computing for other functions of the business from distributors, suppliers, and service providers. The industry has recently made significant progress in wireless technology in resolving some constraints that have affected the widespread adoption of wireless technologies. Some of these constraints have included disparate standards, low bandwidth, and high infrastructure and service cost. Wireless technologies can both support the organizational company mission and provide cost effective solutions. Wireless is being adopted for many new applications such as to connect computers, to allow remote monitoring and data acquisition, to provide control and security, and to provide a solution for environments where wires may not be the best implementation.
4. Computer World Publication, WIRELESS FREEDOM, by Jake Plumwood, November 1, 2001, www.computerworld.com Many of us now find it convenient to connect our PDAs to our LANs to synchronize data and e-mail quickly, to access databases, or to use an Internet connection. Connect your PDA to a WAN in order to send and receive e-mail, to browse the Internet, and for remote access to company data and applications. WANs include telephone networks and digital data networks such as CDPD and Bell South Wireless Data. High-speed Internet connections are also referred to as WANs, but PDAs usually access the Internet through a LAN connection that is in turn connected to the WAN(3, Smith, 10/28/2001, www.networkmagazine.com). It's certainly possible to connect a cable or DSL modem directly to a PDA with a wired Ethernet card (assuming the ISP is configured dynamically). You can connect a PDA to the network via Ethernet cables and devices that slide into or plug onto the PDA, but those connections require you to stay in one place. There are a number of wireless LAN technologies competing for use with desktop PCs, but the only products currently available for PDAs use 802.11b technology. Note that some propose using Bluetooth for LAN connections, but its short range (it can transmit only up to 33 feet, compared with 802.11b's 300-foot indoor limit), low bandwidth (1 Mbps compared to 11 Mbps for 802.11b), and high cost make it a poor choice for this purpose(3, Smith, 10/28/2001, www.networkmagazine.com). For wired Ethernet LAN connectivity, you'll find that expansion cards and cradles, as well as wireless cards, adapters, and expansion jackets compatible with 802.11b networks have become available more recently. As the price of wireless components continues to drop (and as wireless networks like those at airports and Starbucks coffee shops become more common), the convenience of roaming will become ever more attractive. Security is always a factor with networking, and it requires special attention with wireless connections. But the advantages of untethered networking are compelling, especially when applied to PDAs that people use as they move about during the business day(4, Plumwood, 11/01/2001, www.computerworld.com). Obtaining Services & Costs Associated Mobile wireless communication has freed up our need of being wired in. It enables us to communicate virtually anywhere and at any time. It is no longer about just a cell phone; it allows two way high speed data transmission as well. You gain the ability to manage data and possess information about your enterprise when and where you need it. It is changing the business client for customers, clients, suppliers, employees, distributors, retailers, and even financial service providers. Everything is moving into a new global age market into a new business climate throughout the world. Pocket PC's with their full color and motion displays could eliminate the laptop market in the future. The impact of wireless technology will become even more prevalent with the advances of voice to text or text to voice technology, enabling clients to communicate with computers and servers without the functionality of a computer keyboard (3, Smith, 10/28/2001, Wired or Wireless?, www.computerworld.com). This might allow the user to dictate documents, send email, and control some applications all hands free. The voice to text technology will free up the computer desktop, no longer being chained to the desk, with new availability in data communication, it will incre
