  • Patent number: 9761958
    Abstract: One or more access points in a wireless communication system, wherein at least one of those access points includes a set of more than one antennae capable of concurrent communication, and at least one of those more than one antennae is isolated from a remainder of that set of antennae during concurrent communication. Isolation includes one or more of disposed a first antenna in a null region of a second antenna, disposing a first antenna to communicate polarized and substantially orthogonal to a second antenna, disposing a set of antennae to communicate at two or more carrier frequencies, wherein each first antenna adjacent to a second antenna operate at distinct such carrier frequencies, or disposing a set of antennae to communicate using two or more substantially distinct protocols, wherein substantially each first antenna adjacent to a second antenna operate at substantially distinct such protocols.

  • Patent number: 8344953
    Abstract: An access point housing structure includes a first enclosure, a second enclosure to house an array of antenna patches, and an omni-directional hinge component. The first enclosure includes a first coupling mechanism located near one of the corners of the first enclosure. The second enclosure includes a second coupling mechanism located near a corner corresponding to the location of the first coupling mechanism. The omni-directional hinge component connects to the first coupling mechanism and to the second coupling mechanism and allows rotation of the second enclosure about a first axis along an edge of the first enclosure adjacent to the first coupling mechanism and about a second axis along an edge of the second enclosure adjacent to the second coupling mechanism.

  • Patent number: 8160664
    Abstract: An omni-directional antenna supporting simultaneous transmission/reception, from the same AP, on multiple frequencies, allowing each AP to communicate using each possible frequency. Each AP multiplexes its outgoing signals onto its transmitting antenna, and de-multiplexes its incoming signals from its receiving antenna. The transmitting and receiving antennae are each substantially located in each other's NULL zone (or one is in the NULL zone of the other). The AP can transmit/receive on many distinct frequencies without needing more antennae.
