Embedded Wireless Communication : Connectivity of a smartphone with BluetoothLE and UWB devices
Abstract: The next generation (5G) mobile and wireless communications system is expectedto start its deployment in 2020. The 5G system will include various newlydeveloped technologies and enable new applications, among which, for instance,are device-to-device (D2D) communications, and various techniques for Internetof things (IoT). This thesis project aims to develop techniques for connectingsmartphones with small devices (suited for IoT) and for connecting smartphoneto smartphone (suited for D2D communications), using Bluetooth and IEEE802.15.4 ultra wideband (UWB) wireless communications protocols. The mainfocus of the project is on the UWB-based techniques. The project works involvelearning Bluetooth and UWB communications theories and protocols, andimplementing three use cases: 1) connection of a smartphone with a Bluetoothdevice, 2) connection of a smartphone with a UWB-based wireless network, and3) connection of two smartphones through UWB communications. Case 1 and 2 arewell suited for IoT and Case 3 well fits the D2D communications. A prototypefor the three cases has been developed that consists of smartphones (withAndroid operating system), a Bluetooth node (CC2650 development kit from TexasInstruments) and UWB nodes (EVK1000 development kits from DecaWave Inc.,). AnApp has been created that runs on the smartphones to handle Bluetooth and UWBcommunications for transmitting and receiving data. With programs (algorithmsin C/C++) that run on wireless devices and sensor nodes have been developed tohandle measurements from sensors and communications between small devices andsmartphones. The prototype has been tested and shown to work with therequirements satisfied.
