Presence, Location Awareness, Power Management and IP Phone (Infrastructure mode) UCoM Demonstration (Multi-Radio Wireless LAN Research)

Step 1: Presence, Location & Power - Infrastructure Mode SmartBrick is plugged into UCoMProxy ; its presence is detected and registered with UCoMServer

SmartBrick is plugged into UCoMProxy ; its presence is detected and registered with UCoMServer

Step 1: Presence, Location & Power - Infrastructure Mode SmartBrick is plugged into UCoMProxy; its presence is detected and registered with UCoMServer Receiver enters room and MiniBrick registers with the UCoMServer via SmartBrick & UCoMProxy Receiver

SmartBrick is plugged into UCoMProxy; its presence is detected and registered with UCoMServer

Receiver enters room and MiniBrick registers with the UCoMServer via SmartBrick & UCoMProxy

Step 1: Presence, Location & Power - Infrastructure Mode SmartBrick is plugged into UCoMProxy; its presence is detected and registered with UCoMServer Receiver enters room and MiniBrick registers with the UCoMServer via SmartBrick & UCoMProxy UCoMCaller queries UCoMServer to determine MiniBrick ’s presence & location Receiver UCoMCaller

SmartBrick is plugged into UCoMProxy; its presence is detected and registered with UCoMServer

Receiver enters room and MiniBrick registers with the UCoMServer via SmartBrick & UCoMProxy

UCoMCaller queries UCoMServer to determine MiniBrick ’s presence & location

Step 1: Presence, Location & Power - Infrastructure Mode SmartBrick is plugged into UCoMProxy; its presence is detected and registered with UCoMServer Receiver enters room and MiniBrick registers with UCoMServer via SmartBrick & UCoMProxy UCoMCaller queries UCoMServer to determine MiniBrick’s presence & location. UCoMCaller sends a “wakeup” request to MiniBrick via UCoMServer . The UCoMServer forwards request to UCoMProxy & Smart Brick . MiniBrick powers on the Receiver “ Wakeup” “ Wakeup” Receiver Power’s On!

SmartBrick is plugged into UCoMProxy; its presence is detected and registered with UCoMServer

Receiver enters room and MiniBrick registers with UCoMServer via SmartBrick & UCoMProxy

UCoMCaller queries UCoMServer to determine MiniBrick’s presence & location.

UCoMCaller sends a “wakeup” request to MiniBrick via UCoMServer . The UCoMServer forwards request to UCoMProxy & Smart Brick .

MiniBrick powers on the Receiver

Step 2: People Discovery, Location, iPhone Receiver invokes uTalk and registers with UCoMServer according to step 1

Receiver invokes uTalk and registers with UCoMServer according to step 1

Receiver invokes uTalk and registers with UCoMServer according to step 1 Caller invokes uTalk to contact UCoMServer and determine if receiver is present and powered on Step 2: People Discovery, Location, iPhone

Receiver invokes uTalk and registers with UCoMServer according to step 1

Caller invokes uTalk to contact UCoMServer and determine if receiver is present and powered on

Step 2: People Discovery, Location, iPhone Receiver invokes uTalk and registers with UCoMServer according to step 1 Caller invokes uTalk to contact UCoMServer and determine if receiver is present and power on If receiver is present If receiver is powered on then Caller sends call request along with its IP address to UCoMServer , which relays request to receiver else Caller sends a wakeup request to UCoMServer which wakes up receiver

Receiver invokes uTalk and registers with UCoMServer according to step 1

Caller invokes uTalk to contact UCoMServer and determine if receiver is present and power on

If receiver is present If receiver is powered on then Caller sends call request along with its IP address to UCoMServer , which relays request to receiver else Caller sends a wakeup request to UCoMServer which wakes up receiver

Step 2: People Discovery, Location, iPhone Receiver invokes uTalk and registers with the UCoMServer according to step 1 Caller invokes uTalk to contact UCoMServer and determine if receiver is present and power on If receiver is present If receiver is power on then Caller sends a call request along with its IP address to the UCoMServer, which will relay the request to receiver else Caller sends a wakeup request to the UCoMServer which will in turn wake up receiver Receiver opens a connection to caller, and they talk in real-time using the infrastructure network

Receiver invokes uTalk and registers with the UCoMServer according to step 1

Caller invokes uTalk to contact UCoMServer and determine if receiver is present and power on

If receiver is present If receiver is power on then Caller sends a call request along with its IP address to the UCoMServer, which will relay the request to receiver else Caller sends a wakeup request to the UCoMServer which will in turn wake up receiver

Receiver opens a connection to caller, and they talk in real-time using the infrastructure network
