Episode 7 — Master Wireless Bands Channels Standards and Short-Range Radio Technologies Clearly
This episode covers the wireless topics A+ candidates need to understand without getting lost in unnecessary detail. You will compare how 2.4 GHz and 5 GHz Wi-Fi behave in terms of range, speed, and congestion, why channel overlap and interference affect user experience, and how wireless standards shape compatibility and expected performance. The episode also introduces short-range radio technologies such as Bluetooth, NFC, and RFID, with clear examples of where each one appears in business and consumer environments. From an exam perspective, the goal is to recognize what technology fits a given use case and what symptom patterns suggest interference, distance, poor placement, or standards mismatches. In real support work, that means knowing why a device may connect slowly in a crowded area, why a Bluetooth accessory may drop when nearby devices compete for spectrum, or why short-range identification tools are useful for access and tracking rather than full network communication.
