Wireless Networking Technologies

When a user submits a help desk ticket complaining of "slow Wi-Fi," the culprit is rarely a broken router. Usually, the issue is an invisible collision of electromagnetic waves. Wireless networking is fundamentally the engineering of invisible light. An antenna manipulates the electromagnetic spectrum to push data through the air, across walls, and into the devices that modern businesses rely on. As an IT support professional, you cannot see these waves, but you must govern them. To resolve connectivity issues, eliminate interference, and deploy secure networks, you must intimately understand how frequencies behave, how devices negotiate airspace, and how short-range protocols connect the peripherals on a user's desk.
