| 1 | 2 | ptrkrysik | A BTS (Base Transceiver Station) on the GSM radio interface may use frequency hopping, that |
|---|---|---|---|
| 2 | poses additional difficulty to transmit and receive GSM signals on the mobile side. The aim of this |
||
| 3 | subtask is to implement frequency hopping for a GSM mobile station. |

| 4 | 1 | ptrkrysik | |
| 5 | 2 | ptrkrysik | * implementing transmission of GSM bursts according to a hopping sequence (deliverables: |
| 6 | code + plot(/s) showing frequency of transmitted bursts) |
||
| 7 | * implementing reception of GSM bursts that follows frequency hopping (deliverables: code + |
||
| 8 | decoded messages from the signal with hopping) |
||
| 9 | * extending the control interface between gr-gsm and Osmocom-BB with ability to |
||
| 10 | send/change hopping parameters (deliverable: code) |
||
| 11 | * testing the mobile station with a GSM BTS supporting frequency hopping (deliverable: |
||
| 12 | protocol traces in Wireshark) |
