    摘要: A method and apparatus for calculating a location of a device is provided. A likelihood of the device being located at a particular location point or a particular location floor is determined using a likelihood calculation at each of a plurality of locations. The location point or location floor is then identified as that location having an associated highest likelihood calculation. The likelihood calculation includes calculating a distance from the device to each of a plurality of reference routers including one or more virtual coplanar reference routers, wherein each of the one or more virtual coplanar reference routers comprise a projection of a non-coplanar reference router onto the floor.

    摘要: A node in a wireless communication system announces a channel switch operation to facilitate a smooth transition to other channel. The node detects a requirement to discontinue communications at a first channel and sends a message to a plurality of neighboring nodes in response to detecting the requirement. Generally, the message comprises at least a reason for discontinuation of communications at the first channel and a duration for the channel switch operation after which the node is available for communications at the first channel or an alternate channel. Each of the plurality of neighboring nodes can determine based on the message and the neighborhood conditions a requirement to scan alternate channels to initiate communications with other nodes.
