Patent number: 7251224Abstract: A method is disclosed for assigning timeslot numbers to timeslots used for transmission and reception of signals between nodes in a network (1) of nodes (A–H). Each node (A–H) is able to communicate with at least one other node (A–H) by a transmission link (2) between said each node (A–H) and said at least one other node (A–H). At least some of the nodes (A–H) have a respective transmission link (2) to each of plural other nodes (A–H). Each transmission of a signal over a link (2) from a first node (A–H) to a second node (A–H) takes place during a timeslot. The method includes the steps of assigning timeslot numbers to each timeslot in sequence in ascending order of the number of available choices of timeslot number at each timeslot.Type: GrantFiled: October 9, 2001Date of Patent: July 31, 2007Assignee: Intel CorporationInventors: Stephen Ades, Philip T. Hughes, Malcolm C. Taylor

Patent number: 7099297Abstract: A communications system (1) includes a plurality of nodes (2). Each node (2) has receiving means for receiving a signal transmitted by wireless transmitting means; transmitting means for wireless transmission of a signal; and, means for determining if a signal received by said node (2) includes information for another node (2) and causing a signal including said information to be transmitted by said transmitting means to another node (2) if said received signal includes information for another node (2). Each node (2) has one or more substantially unidirectional point-to-point wireless transmission links (3). At least some of the nodes (2) have plural substantially unidirectional point-to-point wireless transmission links (3). Each of said links (3) is to one other node (2) only. The links (3) are arranged such that at least some of the nodes (2) are not linked only to the nearest neighbor node(s) (2).Type: GrantFiled: August 10, 2001Date of Patent: August 29, 2006Assignee: Radiant Networks PCInventors: Philip T. Hughes, Timothy Jackson, James Newman

Each node (2) has one or more substantially unidirectional point-to-point wireless transmission links (3). At least some of the nodes (2) have plural substantially unidirectional point-to-point wireless transmission links (3). Each of said links (3) is to one other node only (2). Each node (2) is arranged such that transmission or reception of a signal at any particular frequency by a node (2) takes place on only one link (3) at a time.Type: GrantFiled: August 10, 2001Date of Patent: July 25, 2006Assignee: Radiant Networks PLCInventors: Philip T.

Patent number: 7061883Abstract: A communications system (1) includes a plurality of nodes (2). Each node (2) has receiving means for receiving via an antenna (13) a signal transmitted by wireless transmitting means; transmitting means for wireless transmission of a signal via an antenna (13); and, means for determining if a signal received by said node (2) includes information for another node (2) and causing a signal including said information to be transmitted by said transmitting means to another node (2) if said received signal includes information for another node (2). Each node (2) has one or more substantially unidirectional point-to-point wireless transmission links (3). At least some of the nodes (2) have plural substantially unidirectional point-to-point wireless transmission links (3) which share at least one of a receiver (10) of the receiving means and a transmitter (11) of the transmitting means. Each of the links (3) is to one other node (2) only.Type: GrantFiled: August 10, 2001Date of Patent: June 13, 2006Assignee: Radiant Networks PLCInventors: Philip T. Hughes, Timothy Jackson, James Newman

Patent number: 6553020Abstract: A communications system (1) has a plurality of nodes (2). Each node (2) has a receiver (10) for receiving a signal transmitted by wireless transmitting means and a transmitter (11) for wireless transmission of a signal. Each code (2) further has means for determining if a signal received by said node (2) includes information for another node and causing a signal including said information to be transmitted by said transmitting means to another node if said signal includes information for anode node. Each node (2) has a substantially unidirectional point-to-point wireless transmission link (3) to at least one other node. The communications system (1) has high spectral efficiency compared to a broadcast cellular system and allows high data transfer rates to be achieved.Type: GrantFiled: June 17, 1999Date of Patent: April 22, 2003Assignee: Radiant Networks PLCInventors: Philip T. Hughes, Timothy Jackson, James Newman
