1. 16. 5G user satisfaction enabled by FASP : Evaluating the performance of Aspera's FASP

   Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

   Författare :Patrik Hagernäs; [2015]
   Nyckelord :TCP; 5G; emulated radio access network; handover; FASP; CUBIC TCP; packet loss; TCP; 5G; överlämningar; FASP; CUBIC TCP; tappade paket; radioaccessnät;

   Sammanfattning : With Ericsson’s goal to have optimal user experience at 5G’s 2020 release, it is very important to optimize transport protocols and techniques to manage the increasing amount of data traffic. Additionally, it will be important to manage handovers between very high speed 5G networks and older networks. LÄS MER

3. 17. Improving eciency of EMC ImmunityMonitoring of RBS using a FPGA basedinstrument

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

   Författare :Viktor Arfwedson; [2014]
   Nyckelord :LTE; Immunity testing; Ericsson; National Instruments; VST; PXI; FPGA;

   Sammanfattning : A test system for Immunity testing of Ericsson's LTE radiobase station (RBS) was built using a National Instruments(NI) PXI chassis tted with a vector signal transceiver (VST)module and a PC controller module. A program made in Lab-VIEW and MATLAB was run on the controller module in thePXI chassis. LÄS MER

4. 18. Evaluating the use of PXI modules in tests of a radio base station

   Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

   Författare :Willy Wang; [2014]
   Nyckelord :Vector signal transceiver VST ; multiple radio access technology multi-RAT ; PCI extension for instrumentation PXI ; LabVIEW; testing; Vektorsignal transceiver VST ; multipel radioteknik multi-RAT ; PCI extension for instrumentation PXI ; LabVIEW; testning;

   Sammanfattning : This thesis project was carried out at the electromagnetic compatibility (EMC) department at Ericsson AB. One of the department’s goals is to seek a possible replacement to the box test instruments by utilizing PCI extension for instrumentation (PXI) modules. LÄS MER

5. 19. Extending the precision time protocol to a metropolitan area network : Synchronizing radio base stations

   Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

   Författare :Mozhdeh Kamel; [2014]
   Nyckelord :precision time protocol; radio base station; synchronization; precisions tid protokoll; radiobasstation; synkronisering;

   Sammanfattning : When building various types of wide area cellular radio networks there is a need to synchronize all of the base stations within a given system. Today this is typically done by attaching a highly accurate clock to each radio base station. A GPS radio receiver is commonly used as such a clock. LÄS MER

7. 20. Verification technique for fault management system of digitalunit of radio base station

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Saad Fakher; [2014]
   Nyckelord :;

   Sammanfattning : With the evolution of technology the system becomes large and complex. The probability of faults to occur in the system also increases with the size of the system. LÄS MER
