A system and device for harvesting various frequencies and polarizations of ambient radio frequency (RF) electromagnetic (EM) energy for making a passive sensor (tag) into an autonomous passive sensor (tag) adapted to collect and store data with time-stamping and some primitive computation when necessary even when an interrogating radio frequency identification (RFID) reader is not present (not transmitting). A specific source of ambient RF EM energy may include wireless fidelity (WiFi) and/or cellular telephone base stations. The system and device may also allow for the recharging of energy storage units in active and battery assisted passive (BAP) devices. The system could be a “smart building” that uses passive sensors with RF EM energy harvesting capability to sense environmental variables, security breaches, as well as information from “smart appliances” that can be used for a variety of controls and can be accessed locally or remotely over the Internet or cellular networks.

Apparatus and methods implement aggregation frames and allocation frames. The aggregation frames include a plurality of MSDUs or fragments thereof aggregated or otherwise combined together. An aggregation frame makes more efficient use of the wireless communication resources. The allocation frame defines a plurality of time intervals. The allocation frame specifies a pair of stations that are permitted to communicate with each other during each time interval as well as the antenna configuration to be used for the communication. This permits stations to know ahead of time when they are to communicate, with which other stations and the antenna configuration that should be used. A buffered traffic field can also be added to the frames to specify how much data remains to be transmitted following the current frame. This enables network traffic to be scheduled more effectively.

When connecting a unit to one or more existing ad hoc wireless networks comprising several units, the units e.g. adapted to communicate according to the Bluetooth specification and the network then being formed according to the same specification to comprise one or more piconets, a unit can discover the units which are the masters in the networks, and then connect as a slave to those masters. Specifically it does not have to use the master-slave switch according to the Bluetooth specification. In the first stage of the unit trying to make a connection it establishes contact with at least one unit in an existing ad hoc network and then additional information on the status, in particular the role of master or slave, of the unit already connected in the network is transferred to the not yet connected unit. This information facilitates the decision of the unconnected unit as to which unit in the network that it should try to correct to. Then, in the actual connecting of the unit to the network, the roles of the unit and of the already connected unit can be chosen by the unit wanting to be connected. In particular, the initially inquiring and paging unit may become a slave unit in a newly formed piconet or in an already existing piconet.

In a blended inbound/outbound call center (100), an outbound call-pacing function (122) decides whether or not to initiate an additional outbound call for a particular skill. It determines (206) whether the number of available agents for the skill plus the number of resting agents for the skill exceeds the number of available inbound calls for the skill plus the number of outstanding outbound calls for the skill. It also determines (312) whether a target service time for the skill exceeds an estimated wait time of each of the available inbound calls for the skill assuming that pending outbound calls for the skill plus one take precedence over the inbound calls. If both determinations are affirmative, the call pacing function initiates (318) an additional call for the skill. If either determination is negative, the function forbears (321) from initiating an additional call for the skill. The number of available and resting agents may be incremented (206) by (a) a difference between the target service time for the skill and the present waiting time of the last-enqueued inbound call for the skill divided by the average rate of advance through the skill's call queue, or (b) the average amount of time that a newly-initiated outbound call for the skill takes to become available divided by the average rate of advance, plus the number of agents for the skill who are busy but expected to become available within a time period equal to (a) or (b), less the number of those agents that will receive a rest period upon becoming idle. The number of calls may be incremented (206) by the number of inbound calls that are expected to arrive within the time period (a) or (b).

According to the invention,the implementation complexity is low, and the performance of multi-user MIMO uplink transmission can be effectively improved.
