Abstract: One or more content providers push data related to: movies, movie products, digital movie content over a network (e.g., a LAN, a WAN, the Internet, or a wireless network) onto an information filling station which, in turn, wirelessly transacts (over a network based on the 802.11b protocol) and transmits any requested data to a portable computer-based device (e.g., laptop, a pen-based computer device, a PDA, a wireless phone, or a pager). The portable device performs financial transactions for: purchasing movie tickets (directly or via auctions), downloading digital entertainment content of interest (e.g., copy of a movie of interest, copy of a movie identified based on a pre-stored profile, copy of soundtrack of a movie of interest), or movie related products. Any purchased digital content is either transferred wirelessly onto the portable device or, optionally, sent on a storage medium to a physical address associated with the profile.

Abstract: A method includes automatically sending a request from a wireless access point to a configuration server during a power-up procedure for the wireless access point. The method includes receiving virtual private network tunnel parameters at the wireless access point from the configuration server in response to the request. The virtual private network tunnel parameters identify an access gateway. The method also includes establishing a virtual private network tunnel between the wireless access point and the centralized access gateway during the power-up procedure based on the virtual private network tunnel parameters. The virtual private network tunnel enables the wireless access point to provide one or more wireless devices access to a wide area network.

Abstract: A technique includes jointly demodulating a desired signal and an interfering signal of a received signal in response to a carrier-to-interference ratio estimate for the received signal being below a threshold level. The jointly demodulating is based on first channel impulse response coefficients associated with the desired signal and second channel impulse response coefficients associated with the interfering signal. The technique includes determining the first channel impulse response coefficients based on a first cross-correlation function between the received signal and a training sequence of the desired signal and determining the second channel impulse response coefficients based on a second cross-correlation function between the received signal and a training sequence of the interfering signal. The second channel impulse response coefficients are determined based on a time difference between a time value of a peak in the first cross-correlation function and a time value of a peak in the second cross-correlation function.
