I-IWAVE Ad-hoc Network System VS DMR System

433 ukubukwa

Yini i-DMR

I-Digital Mobile Radio (DMR) indinganiso yamazwe ngamazwe yemisakazo yezindlela ezimbili edlulisa izwi nedatha kumanethiwekhi omsakazo okungewona awomphakathi. I-European Telecommunications Standards Institute (ETSI) idale izinga ngo-2005 ukubhekana nezimakethe zezentengiselwano. Izinga libuyekezwe izikhathi ezimbalwa kusukela ekudalweni kwalo.

Iyini i-Ad-hoc Network System

Inethiwekhi yesikhangiso iyinethiwekhi yesikhashana, engenazintambo evumela amadivayisi ukuthi axhume futhi axhumane ngaphandle kwerutha emaphakathi noma iseva.Eyaziwa nangokuthi inethiwekhi yesikhangiso seselula (i-MANET), iyinethiwekhi ezilungiselela yona yamadivayisi eselula akwazi ukuxhumana ngaphandle ukuthembela engqalasizinda ekhona ngaphambili noma ekuphathweni okumaphakathi. Inethiwekhi yakheka ngokushintshashintshayo njengoba amadivayisi eza ebangeni elinye nelinye, eliwavumela ukuthi ashintshisane ngedatha kontanga kuya-kontanga.

I-DMR idume kakhulu imisakazo ephathwayo yokuxhumana okulalelwayo okubili. Kuthebula elilandelayo, Mayelana nezindlela zokuxhumana, senze ukuqhathanisa phakathi kwesistimu yenethiwekhi ye-IWAVE Ad-hoc kanye ne-DMR.

 

  IWAVE Ad-hoc System I-DMR
Isixhumanisi esinezintambo Asikho isidingo Kudingeka
Aqale ucingo Ngokushesha njengama-walkie-talkies avamile Ucingo luqalwa yishaneli yokulawula
Ikhono lokulwa nomonakalo Iqinile

1. Uhlelo aluncikile kunoma yisiphi isixhumanisi esinezintambo noma ingqalasizinda engashintshi.

2. Ukuxhumana phakathi kwedivayisi ngayinye akungenantambo.

3. Idivayisi ngayinye inikwa amandla ibhethri eyakhelwe ngaphakathi.

Ngakho, lonke uhlelo lunamandla okulwa nomonakalo

Buthaka

1. I-hardware iyinkimbinkimbi

2. Ukusebenza kwesistimu kuncike kuzixhumanisi ezinezintambo.

3. Uma ingqalasizinda isicekelwe phansi yinhlekelele. Uhlelo ngeke lusebenze ngokujwayelekile.

ngakho, ikhono layo lokulwa nokulimala libuthakathaka.

Shintsha 1. Asikho isidingo sokushintsha okunezintambo
2. Isebenzisa inkinobho yomoya engenantambo
Ukushintsha kuyadingeka
Ukumboza Ngenxa yokuthi isiteshi esiyisisekelo samukela ubuchwepheshe be-mirroring, i-rf idluliswa ngemisebe. Ngakho-ke, uhlelo lunokufakwa okungcono okunezindawo ezimbalwa eziyimpumputhe Ezinye izindawo ezingaboni lutho
Inethiwekhi ye-ad hoc engenasikhungo Yebo Yebo
Umthamo wokunweba Nweba umthamo ngaphandle komkhawulo Ukunwetshwa okukhawulelwe: Kukhawulelwe imvamisa noma ezinye izici
Izingxenyekazi zekhompuyutha Isakhiwo esilula, isisindo esincane kanye nosayizi omncane Isakhiwo esiyinkimbinkimbi nosayizi omkhulu
Kuyazwela -126dBm I-DMR: -120dbm
Isipele esishisayo Iziteshi eziningi eziyisisekelo zingasetshenziswa ngokuhambisana ukwenza isipele esishisayo esihlangene Ayisekeli ukwenza isipele esishisayo ngokuqondile
Ukuthunyelwa okusheshayo Yebo No
