Isingeniso
Umsakazo we-IWAVE PTT MESHkwenza izicishamlilo zikwazi ukugcina ukuxhumana kalula ngesikhathi somcimbi wokucisha umlilo esifundazweni sase-Hunan.
I-PTT (Push-To-Talk) egqokwa umzimbaibhande elincane MESHimisakazo yethu yakamuva yomkhiqizo inikeza ukuxhumana okusheshayo kwe-push-to-talk, okuhlanganisa ukushaya ucingo komuntu oyedwa kuya koyedwa, ukushaya kweqembu elilodwa kuya kwabaningi, konke ukushaya, nokushaya ucingo oluphuthumayo.
Ngendawo ekhethekile engaphansi komhlaba nengaphakathi, ngokusebenzisa i-topology yenethiwekhi ye-chain relay kanye nenethiwekhi ye-MESH, inethiwekhi engenantambo ye-multi-hop ingasatshalaliswa ngokushesha futhi yakhiwe, okuxazulula ngempumelelo inkinga yokuvaleka kwesignali engenantambo futhi ibone ukuxhumana okungenantambo phakathi komhlabathi nangaphansi. , isikhungo somyalo sangaphakathi nangaphandle.

Ingemuva
Ntambama ngoSepthemba 16, 2022, kwaqubuka umlilo esakhiweni saseChina Telecom esifundazweni saseHunan. I-Lotus Garden China Telecom Building yaba yisakhiwo sokuqala e-Changsha ukweqa amamitha angu-200 nobude obungamamitha angu-218.
Yayaziwa nangokuthi isakhiwo eside kunazo zonke e-Hunan ngaleso sikhathi. Kusengenye yezakhiwo eziyingqophamlando zaseChangsha ezinobude besakhiwo obungamamitha angama-218, izitezi ezingama-42 ngaphezu komhlaba kanye nezitezi ezi-2 ngaphansi komhlaba.
Inselele
Phakathi nenqubo yokucisha umlilo, lapho izicishamlilo bengena esakhiweni ukuze zifune futhi zihlenge, imisakazo evamile ye-DMR kanye nemisakazo yenethiwekhi yamaselula ayikwazanga ukufeza umyalo nokuxhumana ngenxa yokuthi kwakunezindawo eziningi ezingaboni emehlweni kanye nezithiyo ngaphakathi kwesakhiwo.
Isikhathi ukuphila. Lonke uhlelo lwezokuxhumana ludinga ukwakhiwa ngesikhathi esifushane. Ngakho-ke asikho isikhathi esanele sokuthola indawo efanelekile yokubeka i-repeater. Yonke imisakazo kufanele ibe yinkinobho eyodwa ukuze isebenze futhi ixhumane ngokuzenzakalela nayo ngayinye ukuze imise inethiwekhi yomsakazo we-mesh ukuze ihlanganise sonke isakhiwo ukusuka ku -2F kuya ku-42F.
Enye imfuneko yesistimu yezokuxhumana ukuthi kwakudingeka ikwazi ukuxhuma isikhungo somyalo esisendaweni ngesikhathi somcimbi wokucisha umlilo. Kukhona iloli lokucisha umlilo eduze nomsebenzi wokwakha i-telecom njengesikhungo somyalo sokuxhumanisa yonke imizamo yamalungu okusindisa.
Isixazululo
Esimeni esiphuthumayo, ithimba labasekeli bezokuxhumana livula ngokushesha isiteshi somsakazo se-IWAVE se-handset mesh meSH esinothi oluphakeme ku-1F yesakhiwo se-telecom. Ngesikhathi esifanayo, iyunithi yesibili i-TS1 nayo yatshalwa emnyango we -2F.
Khona-ke imisakazo yesiteshi sesisekelo se-2units TS1 yaxhuma ngokushesha yodwa ukuze kwakhiwe inethiwekhi enkulu yokuxhumana ehlanganisa sonke isakhiwo.
Izicishamlilo ziphethe iziteshi eziyisisekelo ze-TS1 kanye nemisakazo ye-handset ye-T4 ngaphakathi kwesakhiwo. Kokubili i-T1 ne-T4 zijoyina ngokuzenzakalelayo inethiwekhi yokuxhumana yezwi ye-adhoc futhi yandise inethiwekhi iye noma yikuphi ngaphakathi kwesakhiwo.
Ngohlelo lwerediyo ye-IWAVE ye-tactical manet, inethiwekhi yokuxhumana ngezwi imboze sonke isakhiwo ukusuka ku--2F ukuya ku-42F kanye nemoto yomyalo esendaweni bese isignali yezwi idluliswa ukude esikhungweni sokuyala esijwayelekile.
Izinzuzo
Phakathi nenqubo yokuhlenga, izakhiwo ezingaphansi komhlaba, imigudu namabhilidi abanzi ngokuvamile anezindawo ezinkulu zokungaboni ngaso linye. Lokhu kwenza ukutakula kube nzima kakhulu. Emaqenjini okutakula ahlakaniphile, ukuxhumana okubushelelezi nokuthembekile kubalulekile. Uhlelo lwe-IWAVE lwe-MANT lusekelwe kubuchwepheshe benethiwekhi ye-narrowband ad hoc, futhi wonke amadivaysi anezici zokusebenza zokusatshalaliswa okusheshayo kanye ne-multi-hop cascading.
Kungakhathaliseki ukuthi idolobha elinezakhiwo ezinde, izakhiwo ezingaphakathi noma amathrekhi angaphansi komhlaba, imisakazo ye-MANET ye-IWAVE ingamisa ngokushesha inethiwekhi yokuxhumana yezimo eziphuthumayo ngokuvumelana nezimo zendawo futhi ifinyelele ukusakazwa kwenethiwekhi esizeni ngokushesha ngangokunokwenzeka. Ukwengeza ukufakwa kwesignali kuyisimo esidingekayo ukuze kuqinisekiswe ukuthi abatakuli bangakwazi ukusingatha izingozi ngempumelelo futhi benze imisebenzi enzima.
