Kune akawanda makiti akavakirwa paSBC Raspberry Pi, kana pabhodhi rekuvandudza Arduino. Kubva kune zvimwe zvakagadzirirwa kugadzira yako retro consoles, kunyange vamwe yemalaptop, zvishandiso hackable, nezvimwe. Kana iri LibreCellular chirongwa ivo vanoda kuenda kumberi uye kujoina iyo nguva yemafoni nhare uye-inomhanya-mhanya isina waya netiweki vachishandisa mahara Hardware uye software.
LibreCellular inotarisira kufambisa nharembozha mbozhanhare zvichibva pa 4G LTE tekinoroji, uchishandisa yakavhurika sosi software uye Hardware. Kune izvi zvakavakirwa pa SDR (Software Defined Radio), redhiyo yekukurukurirana system uko zvikamu zvakasiyana izvo zvinowanzoitwa mumuviri zvinotsiviwa ne software.
Chinangwa cheLibreCellular
LibreCellular ine chimwe chinangwa, kwete kungoitwa kwe yako nhare yedata nhare shanda, asi zvakare kuti unogona kuzvigadzira nemutengo wakaderera. Kune rimwe divi, ivo vakaisawo ino system kumiedzo yakaoma kwazvo kuti isimbise kuti inoshanda nemazvo, uye ivo vakaipa nemidziyo uye zvinyorwa zvevagadziri izvo zvavanenge vachida.
Zvese zvinhu zvinozo nyorwa chirongwa ichi zvichave pasi peakavhurika sosi marezinesi, uye mamwe ma module anotarisirwa kusvika kuti arambe achizadzisa basa iri. Chinhu chinotarisa kuyedza kwese pakubatanidza, kuyedza, kurongedza uye zvinyorwa kuti zviite chirongwa chinogoneka uye kugadzira mhinduro dzakasiyana nenzira inochinja.
LibreCellular basa rekutanga richava kuvhura iyo kuenderera nekubatanidzwa (CI) chikuva. Ndokunge, gadzira chikuva chekusimudzira umo vagadziri vanogona kusanganisa sosi kodhi shanduko kuita yepakati repodhi uye / kana kudzoreredzwa kwehardware.
Kuedza kunozoitwa zvakare kupedzisa SDR base chiteshi cheredhiyo frequency uye telecommunication yeaya maratidziro, pamwe nekugadzira inodiwa bvunzo michina, RF yekuparadzira network, uye mabhanga e LTE modems yekubatanidza. Kana zvese zvivakwa zvatanga kushanda, tarisiro inozoenda kune iri pamusoro: nhare yekubatanidza, kurongedza, uye zvinyorwa.
Zvirongwa zveProjekiti
Iyo LibreCellular chirongwa chinogadzirwa nemahara uye software zvikamu, sezvandakambotaura. Zvese zvaunoda kuti upe yakakosha LTE data sevhisi uye rutsigiro zvakare yezwi mafoni. Kuti izvi zvikwanisike, zvikamu zvinotevera zvinofanirwa kuve zvakasanganiswa:
- Hardware CI chikuva- Yechiteshi chechiteshi chine LTE modem mabhengi pamusoro peiyo wired RF network, ine chiyero cheRF, kudzora uye revhizheni yekuparadzira wachi.
- Kugadziriswa uye kuyedzwa: ichaitwa kuburikidza nekushandisa software OsmoGMTester, uye kufukidzwa kuchawedzerwa sekuvandudza kuri kuchinja. Mune mamwe mazwi, inozoenda ichibva kune yakasarudzika sevhisi uko vamwe vanyoreri nhare mbozha vanogona kusunganidzwa kune yakazara yakazara sevhisi neVoLTE izwi rekudaidza kugona nekuda kweiyo IP multimedia system (IMS).
- Software stack: zvese izvi Hardware zvichaperekedzwa nesoftware iyo inobvumidza kutaurirana.
- Referensi Hardware chikuva- Ichi chichava chinangwa chakakosha, sezvo ichi chengetedza yakawanda nguva yekuita vashandisi vatsva kusimuka uye ichaita kuti matambudziko ekugadzirisa matambudziko ari nyore.
- Kugadziriswa kwebaseband: SBC inoshandiswa Intel NUC7i7DNBE kumhanyisa baseband uye epamusoro matara eiyo inofamba stack.
- SDR Hardware: iyo ndiro yakasarudzwa LimeSDR-USB.
- RF inowanikwa: redhiyo frequency iyo projekiti ichashandiswa LimeRFE iyo ichazopa yakazara multiband RF kumberi-ent neLNA, PA uye ma duplexers. Uye zvakare, inopa modulated kuburitsa pa24 dBm mune anofamba mabhendi 1, 2, 3, 4 uye 5.
- Tarisa uone: yeiyo revhizheni wachi iyo inoshandiswa neLimeSDR, a GPS Leo Bodnar Mini Kugadziriswa kugadzirisa kugadzikana uye kurongeka kwechiratidzo.
