Being flexible in business is an essential factor these days. The wireless solution, a cost-effective and secure technology, allows for building mobility and versatility. Wireless technology is the same as the technology used in a mobile phone. It uses radio waves to carry data from one point to another. However, one disadvantage with the wireless is that the user must be in the access range. Wireless LAN uses a radio communications device called an access point to connect to the network computers. Access points are small and lightweight, with an antenna attached to send data back and forth over the airwaves. Wireless networks are usually inexpensive and easy to maintain. Wireless networks eliminate the cost of setting up a wired network, which typically means running Cat-5 cable through the ceiling and walls of the office to each workstation or computer. It is also cost effective and saves the time required for the cable installation. One major advantage is that shifting is easy with a wireless network. Some of the major advantages of wireless networks are increased productivity, security, easy set up, faster access, efficient collaboration, and industry solutions provided by the companies. Since wireless network provides convenient access to local network resources and Internet connections, the laptop or the notebook computer can be taken anywhere inside or outside the office, increasing productivity. It is important to understand that the security level in wireless network technology is the same as the type of security existing on wired networks in conjunction with existing network security technology. Wireless network provides quick access to the network server. Also, it is easier to share files or exchange e-mails with the team on-site or off-site. It makes it easier to connect to the company intranet. For a wireless network connection, the user needs a wireless router, Wi-Fi ready computers and LAN capability or a wireless add-in card. Wireless laptops can be used from a broad range of locations like cafes hotels, and airports. These places would have a hotspot that can be detected by the wireless laptop. Hotspots are usually free or fee based. While using wireless laptops in public places, it is suggested to turn off file sharing and avoid sending or receiving sensitive email or personal data. Users should activate a firewall if possible. Always use VPN to connect to work or school from public places. |
