The system includes a plurality of mobile communication devices each having a first communication interface and a second communication interface. The first communication interface enables the mobile communication devices to access a mobile communication network which utilizes a second communication protocol, and the second communication interface enables the mobile communication devices to communicate with the access control readers. The plurality of physical access control readers exchange status information for the plurality of physical access control readers and for the plurality of mobile communication devices over the reader network. ## Claims ### Claim 1 An access control system, comprising: a plurality of physical access control readers that form a reader network which utilizes a first communication protocol; and a plurality of mobile communication devices each having a first communication interface and a second communication interface, wherein the first communication interface enables the mobile communication devices to access a mobile communication network which utilizes a second communication protocol, wherein the second communication interface enables the mobile communication devices to communicate with the access control readers, wherein the plurality of physical access control readers exchange status information for the plurality of physical access control readers and for the plurality of mobile communication devices over the reader network. ### Claim 2 (depends on 1) The access control system of claim 1, wherein the second communication interface utilizes a third communication protocol. ### Claim 3 (depends on 2) The access control system of claim 2, wherein the second communication interface is one of a Bluetooth Low Energy (BLE) interface, a WiFi interface, a near field communication (NFC) interface, and a Zigbee interface. ### Claim 4 (depends on 3) The access control system of claim 3, wherein each of the plurality of physical access control readers includes a memory to store the status information. ### Claim 5 (depends on 4) The access control system of claim 4, wherein the status information includes first information regarding a physical location of each mobile communication device relative to locations the physical access controller readers in the reader network. ### Claim 6 (depends on 5) The access control system of claim 5, wherein the status information includes second information to identify active and inactive physical access control readers in the reader network and their current condition, and wherein the status information includes third information to identify which of the plurality of mobile communication devices are currently connected to the reader network. ### Claim 7 (depends on 6) The access control system of claim 6, wherein the memory stores the first, second, and third information in respective logs. ### Claim 8 (depends on 4) The access control system of claim 4, wherein the memory stores guidance information, and wherein, in response to an emergency event, the reader network sends the guidance information to the plurality of mobile communication devices. ### Claim 9 A method for an access control system, the method comprising: forming a first network that enables communication between a plurality of physical access control readers; forming a second network that enables communication between the plurality of physical access control readers and a plurality of mobile communication devices; and exchanging, over the first network, status information for the plurality of physical access control readers and for the plurality of mobile communication devices. ### Claim 10 (depends on 9) The method of claim 9, wherein the forming the second network occurs in response to an emergency event. ### Claim 11 (depends on 9) The method of claim 9, further comprising: determining, by one or more of the plurality of physical access control readers, locations of the mobile communication devices relative the one or more of the plurality of physical access control readers based on the exchanged status information; and providing, over the second network, guidance information to one or more of the plurality of mobile communication devices based on the determined locations. ### Claim 12 (depends on 11) The method of claim 11, wherein the guidance information includes at least one of audio and video relating to a premises in which the plurality of physical access control readers are located. ### Claim 13 (depends on 12) The method of claim 12, wherein the video includes a map that updates in real time to show a location of the one or more of the plurality of mobile communication devices within the premises. ### Claim 14 (depends on 9) The method of claim 9, further comprising: detecting a change in a number of the plurality of physical access control readers that are in the first network; and providing a notification of the change to one or more of the plurality of mobile communication devices, wherein the notification includes information to identify where the detected change occurred within the first network. ### Claim 15 (depends on 9) The method of claim 9, wherein the status information includes at least one of: one or more first quantities sensed by one or more of the plurality of physical access control readers; and one or more second quantities sensed by one or more of the plurality of mobile communication devices. ### Claim 16 (depends on 15) The method of claim 15, wherein the one or more first quantities and the one or more second quantities each include at least one of temperature information, air quality information, access information, and pressure information. ### Claim 17 (depends on 9) The method of claim 9, further comprising: storing the status information on at least one of the plurality of physical access control readers and on at least one of the plurality of mobile communication devices. ### Claim 18 A device, comprising: a first interface to communicate with first devices according to a first communication protocol over a first network; a second interface to communicate with second devices according to a second communication protocol over a second network, wherein the second communication protocol is different than the first communication protocol; a memory including executable instructions; and a processor to execute the instructions to control the exchange of status information for the first devices and the second devices over the first network. ### Claim 19 (depends on 18) The physical access control reader of claim 18, wherein the first devices are physical access control readers, and the second devices are one or more mobile communication devices. ### Claim 20 (depends on 19) The physical access control reader of claim 19, wherein the memory stores the status information, and wherein the status information includes at least one of: one or more first quantities sensed by one or more of the plurality of physical access control readers; one or more second quantities sensed by one or more of the plurality of mobile communication devices, wherein the one or more first quantities and the one or more second quantities each include at least one of temperature information, air quality information, access information, and pressure information; first information regarding a physical location of each mobile communication device relative to locations the physical access controller readers in the reader network; second information to identify active and inactive physical access control readers in the reader network and their current condition; and third information to identify which of the plurality of mobile communication devices are currently connected to the reader network.
