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

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
  MiniBricks 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
  MiniBricks 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

7
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

8
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

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
