   Abstract : In recent years cars are becoming more and more connected and it has become commonplace to connect one’s phone to the car interface, allowing streaming of music, making calls and sending messages. The primary technology used for connection is Bluetooth, a short-ranged wireless communication technology that has been around since 1999 and improved and expanded upon ever since. READ MORE

4. 3. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Magnus Wasting; [2021]
   Keywords : Discrete; time; filter; NB-IoT; Charge; Sharing; CMOS; Technology and Engineering;

   Abstract : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. READ MORE

5. 4. Parasitic Tracking Mobile Wireless Networks

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Bowen Xu; [2021]
   Keywords : Location privacy attack and evaluation; mobile network simulation; parasitic attacker; Heuristic LSTM;

   Abstract : Along with the growth and popularity of mobile networks, users enjoy more convenient connection and communication. However, exposure of user presence in mobile networks is becoming a major concern and motivated a plethora of LPPM Location Privacy Protection Mechanisms (LPPMs) have been proposed and analysed, notably considering powerful adversaries with rich data at their disposal, e.
