Our network has control capability also, soWireless Sense & Control Network (WSCN) might be a better term.All wireless communication is secured with 128-bit AES encryption. A password can be used to lock a mote so it will not joinunauthorized networks.A SkyMote network has a tree topology: SkyMote Network Tree DiagramSlide 1 / 1 Bridge: A bridge is used to connect the wireless network to a host via Ethernet or USB. Each network has only 1 bridge. Thewireless tranceiver on a bridge is always on. A bridge can have up to 16 children (repeaters and motes).Repeater: Creates a wireless link between 1 parent and up to 16 children. The wireless tranceiver on a repeater is always on.Mote: End-device with sensors and actuators. Generally operated in sleeping mode, where the device (including wirelesstranseiver) is shut down most of the time, and wakes up periodically. A sleeping mote cannot have children. 1
The network device limit (bridge + repeaters + motes) is currently set at 128. SMB-x (Bridge/Repeater)SMB-ETH SkyMote Ethernet BridgeSMB-USB SkyMote USB BridgeSMB-REP SkyMote RepeaterA SkyMote network requires 1 bridge to link the wireless network to a host via USB or Ethernet.The SMB-ETH has all features (SkyMote Wireless, Ethernet, USB, Vjack/Vst), while the SMB-USB and SMB-REP are subsets. SMB Block DiagramSlide 1 / 1 There are 3 ways to provide power to the SMB. Multiple can be connected at the same time, in which case the one with thehighest voltage will actually provide power.Vusb: Power from the USB cable.Vjack: 2.1 x 5.5 mm center-positive power jack.Vst: Screw-terminals. Same specifications as Vjack. [1] 2
[2] FCC PART 15 STATEMENTSTHIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS. (1) THIS DEVICE MAY NOT CAUSEHARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIREDOPERATION.Warning: Changes or modifications not expres s ly approved by the party responsible for compliance could void the us er’s authority to operate thisequipment. Note: This equipment has been tes ted and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules . These limitsare des igned to provide reasonable protection agains t harmful interference in a residential installation. This equipment generates, uses and can radiateradio frequency energy and, if not installed and us ed in accordance with the ins tructions , may caus e harmful interference to radio communications.However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio ortelevision reception, which can be determined by turning the equipment off and on, the us er is encouraged to try to correct the interference by one or moreof the following meas ures :—Reorient or relocate the receiving antenna.—Increase the s eparation between the equipment and receiver.—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.—Cons ult the dealer or an experienced radio/TV technician for help.

This mote also has a microphone that can do some limited sound level measurements. The TLB-RH adds a humidity sensor.802.15.4 end-device with 4 built-in sensors for temperature, light, motion, and sound. Housed in a weather-resistant wall-mountable enclosure designed for indoor or outdoor use. No external connections. 3 AAbatteries power the mote, and battery life is multiple years in typical use.From Wikipedia: Motes - Small, battery-operated sensor nodes operating as part of a Wireless Sensor Network. 3
