In two sizes at $1,000 and $1,500, the portable LCD uses a base station to access 802.11a, b, or g networks: The LocationFree Portable Broadband TV will ship this fall with two options: a 5 pound, 12.1-inch, 800 by 600 pixel display for $1,500, or a smaller 7-inch, 800 by 480 pixel unit for $1,000. The screens connect remote to a base station which has Ethernet, two USB ports, and an NTSC tuner, plus an infrared blaster needed to tune set-top boxes which don't produce tunable signals.
Interestingly, the base station can feed content over the Internet if you have an upload speed of at least 300 Kbps on your local network. Sony can't guarantee the quality of this kind of remote viewing, but has built early 802.11e-like support for quality of service (QoS) packet prioritization and scheduling for crisp local viewing, according to the report. The larger unit has a Compact Flash slot; the smaller, a Memory Stick slot. The portables can view images stored on those cards.
Oddly, the article doesn't mention battery life, but a posting from earlier this year on AkibaLive notes that it has a lithium-ion battery that offers 100 to 180 minutes of viewing on a charge depending on the unit's brightness setting.
