Patent number: 9210719Abstract: Method of accessing a medium on a transmission system having at least two channels, in which a multi-channel device groups at least two channels for the purpose of increasing the bandwidth. The method enables multi-channel devices and single-channel devices to coexist by sending out a preamble and header on each individual channel before the channels are grouped, a single-channel device that may be scanning the channel thus detecting that the message that follows is not intended for itself.Type: GrantFiled: November 10, 2004Date of Patent: December 8, 2015Assignee: Koninklijke Philips N.V.Inventors: Jörg Habetha, Stefan Mangold

Patent number: 9089004Abstract: The present invention relates to the connection of subnets which operate on different frequency channels and are connected by wireless forwarder stations. According to the present invention, a forwarding station periodically switches to the other frequency channel to remain there for a pre-defined presence duration, whereby jitters of the presence time caused by overlapping packet transmissions are compensated. According to the present invention, a presence and absence time of the forwarder station in the respective subnet is indicated by using signals relating to a power saving mechanism.Type: GrantFiled: April 1, 2004Date of Patent: July 21, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jörg Peetz, Yusuf Efe, Jörg Habetha, Klaus Peter May, Olaf Wischhusen

Publication number: 20080317155Abstract: This invention provides a method for dynamically adjusting the transmitter power (PTX) and data rate in a communications system. The scheme is specifically intended for wireless systems based on Code Division Multiple Access (CDMA) or on Multiple Input Multiple Output (MIMO) technology, but can be applied to all systems in which a so-called “Multi-User Detector” can be used. The method includes that the decision whether to increase or decrease the transmitter power (PTX) is based on the Signal to Interference plus Noise Ratio (SINR) at the receiver (S2), whereby the receiver (S2) determines the interference (PIF) with a Multi-User Detector. The interference level (PIF) is then communicated to the sender (S1) or alternatively the receiver (S2) determines the optimal transmitter power level (PTX) and communicates this level to the sender (S1). The proposed method reduces the power consumption and increases the performance e.g. in CDMA based systems.Type: ApplicationFiled: March 28, 2006Publication date: December 25, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Georgios Orfanos, Jorg Habetha

Publication number: 20080009288Abstract: The subnets of a radio network are separated by different scrambling codes. A signalling frame comprises information concerning the spreading code used on the neighbouring or second subnet which can therefore be reserved for a multi hop connection in the first subnet as well. Therefore, in the easiest case the forwarding device only needs to change the scrambling code of the data flow to that of the following subnet and can keep the same spreading code.Type: ApplicationFiled: June 15, 2005Publication date: January 10, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Georgios Orfanos, Jorg Habetha, Francesc Dalmases, Klaus May, Begonya Otal
