Piconet Topology
• Nodes can assume the role of master or slave
  – One or more slaves can connect to a master, forming a
  – The master sets the hopping pattern for the piconet,
    and all slaves must synchronize to that pattern
  – Maximum of 7 slaves controlled by a master

Introduction to Wi-Fi
• Connect electronic devices to each other, to the Internet, and to wired
  networks – quickly and securely
• Most prominent wireless connectivity technology
  for computers and internet
• Consumer devices,
  home/industrial automation,
  security/surveillance, medical
• High data rate,
   (>20Mbps throughput)
• Over 2.5 billion WiFi units
  deployed in the market today,
   1 billion units/year in 2011
WLAN Infrastructure Mode Networks
                   Access Point (AP)
                   • Networks are built to transfer data between stations
                   • Stations can access the Internet through the access
                      point connected to a network
    Access Point   • AP’s serve as the hub to relay all network
                      communications, translating frames between a
                      wireless medium and a wired medium
                   • AP’s are given a service set identifier (SSID), which
                      becomes the network name for the users
                   • AP sends out beacons to let stations know there is an
                      access point they can connect to

                   • Computing devices with wireless network interfaces
                   • Stations associate with an AP to join a network
                   • Stations listen for beacons to understand if any traffic
                      is available
                   • Because stations know when the next beacon is
                      coming, they can go to sleep during this wait period
                      and wake up in time for the next beacon

Smart Config
Connect to a home network in only one step with the world’s
  simplest Wi-Fi configuration scheme

                    Home network name automatically detected or typed by the user
                    User types the network password

                    Group configuration can provision multiple devices at the
                    same time

                    Optional Security Key

                    One step activation
Secured Provisioning with Smart Config
• Smart Config encrypts the SSID and the Password before they are
  send over the air with an AES-128 cipher
• The key used in the encryption is a 128 bit long private secret between
  the CC3000 end point and the configuration application

Service Discovery
Enhance your app experience with easy access to
  SimpleLink devices



Service Discovery with CC3000
• CC3000 supports service discovery using industry
  standard protocols: Bonjour and uPnP

• Integrated with Smart Config to give a great first time
  provisioning experience

• Once provisioned on the network,
   – The CC3000-enabled device can advertise itself within a local link
     network such as a home network
   – Shows up as a new service on a Phone, a Tablet or a PC allowing
     the application to connect quickly and easily to the device
   – Allow easy access to any registered Phone or PC within the home
   – Access to the device can be protected by password
