A portable LCD TV unveiled by Sony needs no tether to a cable or antenna connection, and is so portable it even has a built-in handle.

Sony introduced two models of its LocationFree Portable Broadband TV at the Home Entertainment Expo currently underway in New York City, NY, U.S. The flagship 12.1-in LF-X1 model, weighing about 5 lb with a screen resolution of 800 by 600, will sell for U.S. $1,500. Its 7-in junior, the LF-X5, has a screen resolution of 800 by 480 and will be priced at $1,000, according to Sony representatives. Both models are scheduled to ship this fall, each bundled with a required base station.

The base station has a built-in NTSC tuner, an ethernet port, two video inputs, a USB port (for connecting to an optional analog modem), and an IR Blaster for remote control use. The video source--the cable from your cable box, for example, or an antenna—must be hooked into to the base station. The LocationFree TV can access the signal using one of the three most common types of Wi-Fi (the kit supports all three).

The 802.11g standard is said to offer high speed (up to 54 MB per second) and has good range, but is also subject to interference from other traffic on the 2.4-GHz band that 802.11g uses--microwaves and cordless phones, for example. The 802.11a standard offers similar high-speed rates and is less likely to run into interference, but its range is poor. Sony says in most cases the TV will choose whichever of these Wi-Fi technologies produces the best-quality image. (PC World)
