Tekinoloje ya IWAVE ya single-frequency ad hoc network ndiyotsogola kwambiri, yowopsa kwambiri, komanso ndiyothandiza kwambiri padziko lonse lapansi.
IWAVE's MANET Radio imagwiritsa ntchito ma frequency ndi tchanelo chimodzi kuchita ma frequency amtundu wofanana ndi kutumiza pakati pa masiteshoni oyambira (pogwiritsa ntchito TDMA mode), ndikubweza kangapo kuti azindikire kuti ma frequency amodzi amatha kulandira ndikutumiza ma siginecha (single frequency duplex).
Zaukadaulo:
●Njira imodzi imangofunika ulalo umodzi wopanda zingwe.
●Kulankhulana ndi ma waya opanda zingwe (Adhoc), kuthamanga kwa intaneti.
●Ma network othamanga atha kutumizidwa mwachangu pamalowo kuti amalize "four-hop" multi-base station wireless network.
●Imathandizira ma SMS, ma radio mutual positioning (GPS/Beidou), ndipo imatha kulumikizidwa ku PGIS.
Nawa mafunso aukadaulo ndi mayankho omwe ogwiritsa ntchito amakhudzidwa nawo:
● Pamene makina a wailesi a MANET akugwira ntchito, mawailesi am'manja amatumiza zizindikiro za mawu ndi deta, ndipo zizindikirozi zimalandiridwa ndi kusefedwa ndi maulendo angapo obwerezabwereza, ndipo potsiriza zizindikiro zokhala ndi khalidwe labwino zimasankhidwa kuti zitumizidwe.Kodi dongosololi limachita bwanji zowunikira?
Yankho: Kuwunika kwa siginecha kumatengera mphamvu ya siginecha ndi zolakwika pang'ono.Chidziwitso champhamvu ndikuchepetsa zolakwika pang'ono, ndiye kuti khalidweli limakhala labwino.
●Kodi mungathane bwanji ndi kusokonezedwa kwa ma channel?
Yankho: Lumikizani ndikuwonetsa zizindikiro
●Pamene mukuyang'ana zizindikiro, kodi gwero lokhazikika lapamwamba limaperekedwa?Ngati inde, mungatsimikizire bwanji kuti gwero lokhazikika kwambiri silikhala vuto?
Yankho: Palibe gwero lokhazikika lokhazikika.Kusankhidwa kwa siginecha kumatengera mphamvu ya siginecha ndi zolakwika pang'ono, kenako ndikuwunikidwa kudzera mu ma aligorivimu.
●Pamalo olumikizana, mungatsimikizire bwanji kuyimba kwamawu?Momwe mungatsimikizire kukhazikika kwa kulumikizana?
Yankho: Vutoli likufanana ndi kusankha chizindikiro.Pamalo ophatikizika, makina ofunikira a comms amasankha ma siginecha abwino olumikizirana kutengera mphamvu ya siginecha ndi zolakwika pang'ono.
●Ngati pali magulu awiri A ndi B pa tchanelo chofanana cha ma frequency, ndipo magulu A ndi B amayambitsa kuyimba kwa mamembala nthawi imodzi, padzakhala chizindikiro cholumikizira?Ngati inde, ndi mfundo iti yomwe imagwiritsidwa ntchito popatukana?Kodi kuyimba foni m'magulu onsewa kumatheka bwino?
Yankho: Izo sizidzachititsa chizindikiro aliasing.Magulu osiyanasiyana amagwiritsa ntchito manambala oyimbira osiyanasiyana kuti awasiyanitse, ndipo manambala amagulu osiyanasiyana salumikizana.
●Kodi mawayilesi amtundu wanji omwe anganyamule ndi tchanelo chimodzi chokha?
Yankho: Pali pafupifupi palibe kuchuluka malire.Mawayilesi masauzande ambiri am'manja akupezeka.Pakulankhulana kwachinsinsi pamanetiweki, wailesi ya m'manja sikhala ndi tchanelo pomwe palibe kuyimba, kotero ngakhale pali ma wayilesi angati am'manja, imatha kunyamula.
●Kodi mungawerengere bwanji malo a GPS pa siteshoni yam'manja?Kodi ndi malo amodzi kapena malo osiyana?Chimadalira chiyani?Kodi kulondola kumatsimikizika?
Yankho: IWAVE MANET mawailesi anzeru adamangidwa mu gps / Beidou chip.Imapeza mwachindunji zidziwitso za malo akutali ndi latitude kudzera pa satelayiti kenako ndikutumizanso kudzera pa siginecha ya ultrashort wave.Kulakwitsa kolondola ndikochepera mamita 10-20.
● Pulatifomu yotumizira imakhala ngati gulu lachitatu loyang'anira mafoni mu gulu loyankhulana.Ngati ma tchanelo oyendetsedwa ndi ma frequency amodzi onse akhazikika, kodi tchanelo chidzatsekedwa pomwe wina alowetsa kuyimba mugulu lolumikizana?
Yankho: Ngati nsanja yotumizira imangoyang'anira mafoni, omwe sakhala ndi zida zamayendedwe pokhapokha ngati kuyimba kuyambika.
●Kodi pali zofunika pamayimbidwe amtundu wamtundu womwewo?
Yankho: Ntchito yoyitanitsa gulu ikhoza kupangidwa kudzera pamapulogalamu osinthidwa makonda.
●Pamene gulu lolankhulana lapamwamba likusokoneza mokakamiza, kodi gulu loyankhulana lokhala ndi chizindikiro champhamvu lidzapatsidwa patsogolo?
Yankho: Kusokoneza kumatanthauza kuti wailesi yam'manja yamphamvu kwambiri imatha kusokoneza kuyimba ndikuyambitsa kuyimba kuti mawayilesi ena am'manja ayankhe mawu apawayilesi akuluakulu.Izi ziribe kanthu kochita ndi mphamvu ya chizindikiro cha gulu loyankhulana.
●Kodi zinthu zofunika kuziika patsogolo zimadziŵika bwanji?
Yankho: Powerengera, mlingo wapamwamba umagwiritsa ntchito nambala imodzi, ndipo mlingo wochepa umagwiritsa ntchito nambala ina.
●Kodi kulumikizana pakati pa masiteshoni oyambira kumakhala ngati kukhala ndi tchanelo?
Yankho: Ayi. Chanelo likhala lokhazikika pokhapokha ngati pali kuyimba.
●Base base station imodzi imatha kutumiza ma sign kuchokera kumagulu asanu ndi limodzi olankhulana nthawi imodzi.Ngati ma tchanelo 6 ali otanganidwa nthawi imodzi, padzakhala kusokonekera kwa mayendedwe pamene gulu lapamwamba lolankhulana lisokoneza mokakamiza?
Yankho: Mafupipafupi amodzi amathandizira kuyimba kwamagulu 6 nthawi imodzi, yomwe ndi njira yachindunji pamalopo popanda kutumiza ndi siteshoni yoyambira.Kusokonekera kwa ma Channel kumachitika pamene njira zisanu ndi imodzi zimakhala nthawi imodzi.Dongosolo lililonse lomwe liri lodzaza lidzakhala ndi blockage.
●Munetiweki yofanana yanthawi yofanana, siteshoni yoyambira imadalira gwero la wotchi kuti igwire ntchito mogwirizana.Ngati gwero la kulunzanitsa latayika ndipo nthawiyo idayikidwanso nthawi, kodi pali kupatuka kwa nthawi?Kodi kupatukako ndi chiyani?
Yankho: Co-channel simulcast network base station nthawi zambiri amalumikizidwa kutengera ma satellite.Populumutsa mwadzidzidzi ndikugwiritsa ntchito tsiku ndi tsiku, palibe vuto lomwe gwero la satellite synchronization likutayika, pokhapokha satellite itatayika.
●Kodi nthawi yokhazikitsidwa ndi chiyani mu ms ya kuyimba kwa gulu pa netiweki yofanana ya simulcast?Kodi kuchedwa kwakukulu kwa ms ndi kotani?
Yankho: Onse ndi 300ms
