Om implementering av frekvenshopping i OpenBTS.

Authors: Bremseth, Morten;

Om implementering av frekvenshopping i OpenBTS.

Abstract

Denne Rapporten gir en forklaring på hva programvaredefinert radio er generelt. Den omtaler en konkret realisering ved hjelp av programvaren GNU Radio og den universale radioenheten USRP (Universal Software Radio Peripheral). GSM forklares slik at leseren får den nødvendige oversikten som trengs for å forstå resten av rapporten. Frekvenshopping forklares generelt og hvordan det er gjort i GSM. Det fremstilles en mulig realisering av frekvenshopping med USRP. Programvaren som benyttes for å opprette et GSM-nettverk presenteres. Programvaren som trengs er OpenBTS, GNU Radio og Asterisk. Den fysiske oppkoblingen av USRP når OpenBTS benyttes i programvare GSM blir forklart og hvilket testmiljø eksperimentene ble utført i beskrives. Delvis vellykkede resultater presenteres og rapporten konkluderer med at det skal være mulig å implementere frekvenshopping i OpenBTS med USRP som RF-maskinvare.
