In the early 21st century, 2.4 gigahertz spread spectrum RC control systems have become increasingly utilized in control of model vehicles and aircraft. Now, these 2.4 GHz systems are being made by most radio manufacturers. These radio systems range in price from a couple thousand dollars, all the way down to under US$30 for some. Some ...
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
The Xbox 360 Wireless Microphone is a microphone peripheral designed for use with the rhythm games, Rock Band, Guitar Hero, DJ Hero, Lips, Def Jam Rapstar and Michael Jackson: The Experience. The wireless microphone uses the same 2.4 GHz protocol as the official wireless controller and other peripherals and is powered by 2 AA batteries.
The 900 MHz band is not an option outside of the US and Canada as it is used by GSM cellular mobile phone networks in most other parts of the world. The 2.4 GHz band is increasingly congested with various systems including Wi-Fi, Bluetooth and leakage from microwave ovens. The 6 GHz band has problems of range (requires line of sight) due to the ...
Wireless USB (Universal Serial Bus) is a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group, which is intended to increase the availability of general USB-based technologies.
