The access control devices can be structured to make certain decisions at the access control device and communicate, in real time, information to, as well as receive in real time information from, the access control management host via a networked gateway. The access control device and networked gateway can communicate via a first wireless protocol that at least assists in minimizing the energy of an electrical energy source, such as, for example, a battery, that is coupled to the access control device. Examples of the first wireless protocol can include low latency, low-power wireless technologies or protocols. The networked gateway can communicate with the access control management host using a second protocol via a wired or wireless connection. ## Claims ### Claim 1 An access control device for controlling displacement of an entryway device, the access control device comprising: at least one wireless transceiver; a processing device structured to make a decision relating to the operation of the access control device based at least in part on information stored in the access control device; and wherein the access control device is structured to communicate in real time via a networked gateway using a low latency, low-power wireless technology or protocol. ### Claim 2 (depends on 1) The access control device of claim 1, further comprising a reader device for detecting credential information of a credential device, and wherein the decision made by the processing device is based at least in part on the detected credential information and information stored in a memory of the access control device, the memory coupled to the processing device, and further wherein the access control device is powered by a battery. ### Claim 3 (depends on 2) The access control device of claim 2, wherein the memory includes a user access database, and wherein the decision is a determination of whether credentials detected by the access control device, in view of information in the user access database and the memory, indicates authority to operate the access control device. ### Claim 4 (depends on 3) The access control device of claim 3, wherein the low latency, low-power wireless technology or protocol is at least one of the following: Bluetooth (including Bluetooth low energy (BLE)) and Zigbee. ### Claim 5 (depends on 1) The access control device of claim 1, wherein the access control device is an electronic lock. ### Claim 6 (depends on 5) The access control device of claim 5, wherein the decision is a determination to displace a lock mechanism of the electronic lock from one of an unlocked position and a locked position to the other of the unlocked position and the locked position. ### Claim 7 (canceled) ### Claim 8 (depends on 1) The access control device of claim 1, wherein the access control device is structured to have real time connections with the networked gateway having a duration of less than one second, during which a time the access control device transmits real time communications to the networked gateway. ### Claim 9 (depends on 1) The access control device of claim 1, wherein the access control device maintains a record of certain events during at least an interruption in a networked connection between the access control device and the networked gateway, and further wherein following restoration of the networked connection between the access control device and the networked gateway, the access control device communicates to the gateway device at least an indication of the record of events. ### Claim 10 A system, comprising: an access control device and a networked gateway, the access control device comprising: at least one wireless transceiver; a memory for storing information relating to operation of the access control device; and a processing device coupled to the memory, the processing device structured to make a decision relating to the operation of the access control device based at least in part on information stored in the memory; and wherein the access control device is structured to communicate in real time via the networked gateway using a low latency, low-power wireless technology or protocol. ### Claim 11 (depends on 10) The system of claim 10, further comprising a reader device structured to detect credential information of a credential device, and wherein the decision made by the processing device is based at least in part on the detected credential information, and further wherein the access control device is battery powered. ### Claim 12 (depends on 11) The system of claim 11, wherein the low latency, low-power wireless technology or protocol is at least one of the following: Bluetooth (including Bluetooth low energy (BLE)) or Zigbee. ### Claim 13 (depends on 12) The system of claim 12, wherein the access control device is an electronic lock. ### Claim 14 (depends on 13) The system of claim 13, wherein the decision is a determination to displace a lock mechanism of the electronic lock from one of an unlocked position and a locked position to the other of the unlocked position and the locked position. ### Claim 15 (depends on 14) The system of claim 14, wherein the memory includes a user access database, and wherein the decision is a determination of whether credentials detected by the reader device, in view of information in the user access database and the memory, indicates authority to operate the access control device. ### Claim 16 (canceled) ### Claim 17 (depends on 15) The system of claim 15, wherein the access control device is structured to have real time connections with the networked gateway having a duration of less than one second during which the access control device transmits real time communications to the networked gateway. ### Claim 18 (depends on 17) The system of claim 17, wherein the access control device maintains a record of certain events during at least an interruption in a networked connection between the access control device and the networked gateway, and further wherein following restoration of the networked connection between the access control device and the networked gateway, the access control device communicates to the networked gateway at least an indication of the record of certain events. ### Claim 19 A system, comprising: an access control device, a networked gateway, and an access control management host, the access control device comprising: at least one wireless transceiver; a memory for storing information relating to operation of the access control device; and a processing device coupled to the memory, the processing device structured to make a decision relating to the operation of the access control device based at least in part on information stored in the memory; wherein the access control device is structured to initiate communication in real time with the networked gateway using the first wireless protocol, the first wireless protocol comprising a low latency, low-power wireless technology or protocol; and wherein the networked gateway communicates with the access control management host in real time using a second protocol that is different than the first protocol. ### Claim at position 20 -30. (canceled) ### Claim 31 (depends on 19) The system of claim 19, wherein the access control management host is structured to establish times for the access control device to seek updates. ### Claim 32 (depends on 19) The system of claim 19, further comprising a mobile electronic device; wherein the access control device is structured to transmit at least one of diagnostic results or usage data to the mobile electronic device; and wherein the mobile electronic device is structured to transmit the at least one of the diagnostic results or the usage data received from the access control device to the access control management host. ### Claim 33 (depends on 32) The system of claim 32, wherein the mobile electronic device is further structured to transmit firmware updates to the access control management host; and wherein the access control management host is further structured to push the firmware updates to the access control device.
