Why wireless?
The cost-effectiveness and flexibility of the wireless LANs of the 21st Century, as an alternative to traditional wired networks, are ideal for mobile workers. They allow access to real-time information and corporate resources almost anywhere a mobile worker may be located, and with the growing popularity of wireless “hotspots”, mobile workers can now connect to the Internet at airports, hotels, restaurants, and other public places. Within the last few years, access speeds for WLANs have started to approach those available for conventional wireline networks, making use of wireless networking practical for mainstream business and consumer purposes.
The benefits of wireless networks don’t end outside the office, because with wireless networking, “the air around us is the cable”. Even within modern enterprise offices, workstation mobility, for example using a laptop PC in a meeting room or changing a PC’s location due to organizational changes, is a fact of life. For those who need the flexibility to relocate a workstation, WLANs negate the need for frequent physical wiring changes. This is not just a convenience issue, as cabling changes can amount to a significant burden on already-stressed MIS [Management Information System] and IT [Information Technology] department resources, on top of the costs of the cables themselves. The result? Increased productivity as well as a more positive end-user experience.
