Wireless connectivity comes in many flavors. Wi‑Fi, Bluetooth, and 2.4GHz are often grouped together, but they differ in power consumption, performance, and use cases. Wi‑Fi allows Internet access, Bluetooth pairs audio devices, and 2.4GHz links peripherals to PCs.

The biggest distinction is that only Wi‑Fi supports network connections and can create a local wireless network for dozens of devices. It offers up to 50m range and several Gbps bandwidth, whereas hij Bluetooth tops at about 3 Mbps and 2.4GHz stays under 10 Mbps. Both Bluetooth and 2.4GHz need no router and consume far less power, making them ideal for headphones, keyboards, and mice.

Choosing between them depends on the device. For high performance, low latency, and Internet access, Wi‑Fi is best, though it is power‑hungry. Bluetooth is perfect for simple pairing and battery‑saving peripherals. Some devices, like Android Auto, combine both: Wi‑Fi for map data and Bluetooth for communication.

Many gaming peripherals use 2.4GHz because it offers lower latency—often 1‑5 ms versus up to 30 ms with Bluetooth—and a more stable connection. The band also supports higher polling rates and better audio quality, all while keeping battery life high.
