via cables or wires, a WLAN does its job by using radio waves. Thus, allowing you to connect within your office without the cables or wires. The radio waves pass through ceilings and cement walls to make your WLAN connection.
The same principle works when you are out of your office and using your laptop as well. You may still access to your office wired LAN or wireless WLAN, then access your files or printer that are physically located within your office on your desk! A great productivity gain for the growing number of mobile workers.
But this WLAN technology isn’t just for desk bound office workers. Offices with constantly roving employees stand to gain the most from cutting the cord of traditional wired networks. The power of the Internet is finally coming to places such as hospitals, retail stores and outdoor areas.
The Medical community is using wireless to ease the mounds of medical paperwork involved in keeping patient records, requesting insurance payments and writing prescriptions.
In traditional doctors’ offices, a receptionist takes insurance information, a nurse asks the patient to fill out a questionnaire for symptoms and medical conditions, and the doctor completes a more thorough examination. All this information is taken down on paper, which is then filed away.
Now doctors and nurses may carry around a touch-screen computers, adding bits and pieces of information to each patient’s record as they go from room to room speaking with different patients.
