Abstract: A method for multicasting information, the method includes: utilizing a distributed media access control scheme for allocating at least one timeslot for a transmission of information from a first device to a group of peer devices and for a transmission of acknowledgement messages from the peer devices of the group; and transmitting the information in response to the allocation. A computer readable medium having code embodied therein for causing an electronic device to perform the stages of: utilizing a distributed media access control scheme for allocating at least one timeslot for a transmission of information from a first device to a group of peer devices and for a transmission of acknowledgement messages from the peer devices of the group; and transmitting the information in response to the allocation.

Abstract: A method for dynamically updating transmission characteristics, the method includes: evaluating at least one transmission characteristic in response to a reception of at least one information frame being transmitted over an ultra wideband wireless medium; and transmitting link feedback information and acknowledgement information in response to the reception of the at least one information frame. A device that includes: a receiver adapted to evaluate at least one transmission characteristic in response to a reception of at least one information frame being transmitted over an ultra wideband wireless medium; and transmitter adapted to transmit link feedback information and acknowledgement information in response to the reception of the at least one information frame.

Abstract: A method for expanding a range of an ultra wide band wireless network, the method includes: (i) providing a first network and an external device, the first network includes multiple devices that receive ultra wide band wireless transmissions from each other, the external device is capable of receiving a transmission from a first device of the first network but not capable of receiving a transmission from a second device of the first network; and (ii) allowing the first device to relay transmissions between the external device and the second device. An ultra wide band device that includes: (i) a receiver, adapted to receive transmissions from members of a first network and from an external device not capable of receiving transmissions from a second device of the first network, and (ii) a transmitter, adapted to transmit information to members of the first network and to the external device; wherein the device is adapted to relay transmission from the second device of the first network to the external device.

Abstract: A device and method for ultra wide band transmission, the method includes: (a) allowing a first group of ultra wide band devices to exchange information using a first frequency hopping sequence; and (b) allowing at least one certain device that is responsive to at least one transmission of information from a device of the first group to exchange information using the first frequency hopping sequence during at least one time period and allowing devices that belong to the second group to exchange information using a second frequency hopping sequence during at least one other time period.

Abstract: A method for multicasting information, the method includes: utilizing a distributed media access control scheme for allocating at least one timeslot for a transmission of information from a first device to a group of peer devices and for a transmission of acknowledgement massages from the peer devices of the group; and transmitting the information in response to the allocation. A computer readable medium having code embodied therein for causing an electronic device to perform the stages of: utilizing a distributed media access control scheme for allocating at least one timeslot for a transmission of information from a first device to a group of peer devices and for a transmission of acknowledgement massages from the peer devices of the group; and transmitting the information in response to the allocation.
