Title: Automatic configuration of client terminal in public hot spot.
Inventor: MATHUR SAURABH
IPC: G06F21/00
Filed: 2004-03-12
Abstract: The invention herein provides an apparatus and a method for automatically configuring an IEEE 802.1x client terminal to provide limited access in a WLAN environment, specifically utilizing the access point to filter traffic associated with the limited access so as to redirect the client terminal's HTTP request to a designated local web server. The web server responds to the client terminal by requesting information required to establish an authorized communication. Thereafter the client terminal provides information required to establish an authorized communication. In the course of the communication the web server sends information such as transmission rates, new user account creation information, authentication method selection, and access user terms and conditions of acceptance, all typically required to establish an authorized access. The client responds with information, required to establish an authorized communication.

Title: A method of reducing the power requirements in a mobile radio receiver.
Inventor: ALEX KRISTER RAITH
IPC: H04W52/02
Filed: 1990-08-06
Abstract: IN A RECEIVING CIRCUIT OF A MOBILE TELEPHONE APPARATUS THE INCOMING BASEBAND SIGNALS ARE DEMODULATED AND EQUALIZED SO AS TO COMPENSATE FOR DEFICIENCIES (MULTIPATH PROPAGATION) OF THE RADIO MEDIUM BETWEEN BASE STATION AND MOBILE TELEPHONE APPARATUS. IT IS NOT, HOWEVER, ALWAYS NECESSARY TO EQUALIZE THE DEMODULATED SIGNALS, FOR INSTANCE AT LOW SYMBOL RATES OR IN THE CASE OF MONOPATH PROPAGATION. ACCORDING TO THE INVENTION, TIME DISPERSION OF THE RECEIVED SIGNALS IS ESTIMATED PRIOR TO DEMODULATION, AND DEMODULATION WITH EQULIZATION (3a) IS EFFECTED WHEN THE TIME DISPERSION IS ESTABLISHED TO BE HIGHER THAN A GIVEN VALUE, WHEREAS DEMODULATION WITHOUT EQUALIZATION (3B) IS EFFECTED WHEN THE TIME DISPERSION IS LOWER THAN THIS VALUE. THIS WILL ENABLE THE POWER CONSUMED BY THE RECEIVING CIRCUIT TO BE REDUCED, PARTICULARLY IN THE LISTENING MODE OF THE APPARATUS. (FIG. 4)
