A system for transferring content includes a wireless local area network (WLAN) and a network module provided within the WLAN or a cellular network to alert users of available content in the WLAN and handle user requests made for content when a user has access to the cellular network. The network module, which may comprise an interworking function, delivers the content to the user through the WLAN when the user is present in a coverage area of the WLAN. The invention allows a user to view the pr...

A method for WLAN signal strength determination comprises receiving a WLAN RF signal; converting the WLAN RF signal to a voltage proportional to the signal; comparing the voltage to a first reference voltage; and outputting data corresponding to WLAN RF signal strength if the voltage is greater than the first reference voltage.

A technique for steering a directional antenna such as may be used in a Wireless Local Area Network (WLAN) device. The technique detects signal parameters during reception of short sync pulses in the very beginning portion of a Packet Protocol Data Unit (PPDU) frame. As a result, the antenna can be steered to an optimum direction for reception prior to receiving other portions of a preamble that may be needed to acquire carrier signal phase and frequency.

A pipeline ADC (Analog to Digital Converter) unit is provided that has a first and a second multi-stage portion. The first multi-stage portion has a first plurality of converter stages for converting a first analog signal to a first digital signal having a first digital resolution. The second portion has a second plurality of converter stages to convert a second analog signal to a second digital signal having a second digital resolution. The second plurality includes the first plurality. The pip...

A removable antenna assembly and wireless access point including the same is disclosed in which a plurality of antenna elements are provided for transmitting and receiving wireless signals over a plurality of wireless channels. A sectorized mounting structure is provided for retaining each of the plurality of antenna elements substantially in an antenna isolation configuration, so as to enable simultaneous sectorized signal communication of the antenna elements over the wireless channels. A remo...

A digitally controlled filter tuning method and corresponding WLAN (Wireless Local Area Network) communication devices and integrated circuit chips are provided. A WLAN communication signal is filtered by a tunable filter. A cut-off frequency of the tunable filter is tuned by a feedback loop. Tuning the cut-off frequency includes comparing by a comparator an output signal emitted by the tunable filter to a reference signal and emitting by the comparator a comparator signal indicative of the diff...

A method and system for providing ubiquitous coverage and seamless connectivity for devices which support Internet access via third generation (3G) cellular and IEEE 802.11 wideband local area network (WLAN) technologies, irrespective of which radio access technology is available.

A surface-mountable dual-band monopole antenna includes a substrate and a folded radiative metallic patch with a small metallic lug. The folded radiative metallic patch encloses the substrate, and the small metallic lug protrudes from the substrate, wherein a feeding point is located on the small metallic lug for transmitting the signals.

Real-time handover decision techniques are provided which can utilize prior known system behavior in making a handover decision to avoid averaging delay and hysteresis delay.

The invention relates to a method and system for recording and billing of services during roaming of a mobile IP node (20) in heterogeneous WLANs, in which first call detail records are transmitted from an access server (23/1001) to a billing module (1003) and second call detail records from the access server to a proxy module (1002). By means of a clearing module (1004), the obtained service is billed (1016) at a provider (1008) of a fixed network (1007) and/or TAP files (1017) are transmitted ...
