1. 1. Design of Cellular and GNSS Antenna for IoT Edge Device

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Ioannis Broumas; [2019]
   Keywords : IoT; Internet of Things; Edge device; LTE; 4G; LTE-M1; Antenna; Antenna System; Narrow Band IoT; NB-IoT; Plannar Antennas; GPS; PCB; multiband antenna;

   Abstract : Antennas are one of the most sensitive elements in any wireless communication equipment. Designing small-profile, multiband and wideband internal antennas with a simple structure has become a necessary challenge. READ MORE

3. 2. Pattern Reconfigurable MIMO Antennas for Multiband LTE Operation

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

   Author : Rui Ma; Ioannis Chountalas; [2015]
   Keywords : Technology and Engineering;

   Abstract : Nowadays, multiple antennas are becoming widely used in small mobile terminals as they can significantly improve wireless communication performance in terms of link reliability and spectral efficiency. Also, pattern reconfiguration is another new trend for antenna design as it enables the antennas to adapt to different propagation and user scenarios. READ MORE

4. 3. Implicit Channel Allocation in GSM/EDGE radio networks

   University essay from Institutionen för datavetenskap; Tekniska högskolan

   Author : Emily Leiviskä; [2012]
   Keywords : GSM; EDGE; GPRS packet scheduling; channel allocation; implicit channel allocation; ICA;

   Abstract : Efficient channel allocation in GSM communication is difficult and believed to be a performance bottleneck. This thesis is dedicated to studying the performance of GSM/EDGE networks in modern usage scenarios (surfing the web, chatting and streaming services) under the assumption that explicit channel allocation is not needed.

5. 4. Discrete Cosine Transform for Pre-coded EGPRS

   University essay from KTH/Signalbehandling

   Author : Chengzhou Jin; [2012]
   Keywords : ;

   Abstract : Due to the rapid growth of wireless multimedia service, new features such as improved spectral efficiency, latency and increased peak throughput are standardized in the current GSM/EDGE system. Higher order modulations and symbol rates are defined in Enhanced General Packet Radio Service phase 2 (EGPRS2) to achieve better throughput. READ MORE

6. 5. Performance Evaluation of SpectrumSharing between LTE Femtocell andGSM Networks

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Shen Sun; [2012]
   Keywords : ;

   Abstract : In recent years, as the data traffic demand grows rapidly, GSM spectrum refarming is emerging as one cost effective solution for operators to improve its efficiency on spectrum utilization. Among several refarming strategies, a coexistence network where LTE femtocells share the radio spectrum with the existing GSM users is regarded as one with great potential in the future practice.
