Wireless media players allow media content on a computer to be played on other devices, such as components and TV screens. They connect computers to various consumer electronics using radio frequencies, providing a wider range without using cable connectors. Most models operate at 2.4 and 5.8 GHz frequencies.
Kinds of Wireless Media Players include the following:
Bluetooth wireless media players
Bluetooth wireless media players are used with networked devices transmitting a low to medium speed.
They have maximum download bandwidths of 732 kilobytes per second in half-duplex mode.
They are slower than Wi-Fi models and cannot play real-time or streaming video.
Wi-Fi wireless media players
Wi-Fi wireless media players support high-speed transmissions and provide access to the Internet or a local network.
They are availavble in a, b, and g variants. The a and g variants transmit at about 54 mbps, while the b variant has a maximum speed of 11 Mbps. However, effective rates are about 20 mbps for a and g and 3 mbps for g.
The a variant also operates at 5.8 GHz, while the other two use the 2.4 GHz band.
Frequency: Choose a wireless media player that operates above 2.4 GHz if you have other wireless devices in your home, such as cordless phones. Most wireless home products operate at the same frequency and may interfere with signal reception. Security: Choose a wireless media player with wired equivalent privacy (WEP) encryption to prevent unauthorizes access to your computer via the wireless network. Hackers on the same frequency as the network can obtain confidential information from your computer, such as credit card and social security numbers. Look for one with 128-bit encryption for more secure protection.
