  • Patent number: 6606481
    Abstract: A system provides interactive control of broadband services. There are today systems which offer distributive services, for instance analog cable-TV, analog satellites and acting terrestrial TV-networks. A paradigm shift, however, has been initiated in connection with that digital transmissions have started, which make possible a more spectrum efficient transmission. This means, for instance, that a broadband service such as digital transmission of video channels can be developed by making it interactive. One solution can be to use the GSM-system. For example, services which require low capacity in uplink can utilize the SMS-function is GSM. At larger demand of bandwidth GSM's data services can be utilized, which however prevents calls when the telephone is used for interactive communication. The invention solves this problem by interactive traffic between the transmitting and receiving equipment being managed by an interactive center (IC) which is arranged to execute wanted broadband service.

  • Patent number: 6188873
    Abstract: A broadband radio access method device and system includes a first wireless communication segment that operates under 10 GHz, and a second wireless communication segment that operates over 20 GHz. Coordination between the first segment and second segment occurs when establishing links with a subscriber, such that the broader band services available from the second communication link, are assigned to the subscriber, when the communications channel is available to support line-of-sight communications with the subscriber. When the communications channel does not support the second communication segment, the subscriber is assigned to operate with the first communication segment. An integrated first and second segment terminal is provided to provide a transmodulation device for converting signaling protocols between the two different segments so as to support communications between the subscriber and the intended recipient even if the two use apparently incompatible signaling protocols.
