An ad hoc network inguva pfupi, isina waya network inobvumira zvishandiso kuti zvibatane nekutaurirana pasina chepakati router kana server.Inozivikanwawo senharembozha ad hoc network (MANET), inzvimbo inozvigadzirisa yega yenharembozha inokwanisa kutaura pasina. kuvimba nehurongwa hwagara huripo kana hutongi hwepakati. Iyo network inoumbwa zvine simba sezvo zvishandiso zvinouya muhuwandu hweumwe neumwe, zvichivabvumira kuchinjanisa data peer-to-peer.

DMR inonyanya kufarirwa maredhiyo emafoni ekukurukurirana maviri ekuteerera. Mune tafura inotevera, Panyaya yenzira dzetiweki, takaita kuenzanisa pakati peIWAVE Ad-hoc network system neDMR.

 

  IWAVE Ad-hoc System DMR
Wired link Hapana chikonzero Zvinodiwa
Tanga kufona Nekukurumidza senguva dzose walkie-talkies Kufona kunotangwa nechiteshi chekutonga
Anti-kukanganisa kugona Strong

1. Iyo sisitimu haivimbi kune chero wired link kana yakagadziriswa hurongwa.

2. Kubatana pakati pemudziyo wega wega hakuna waya.

3. Chigadzirwa chimwe nechimwe chinofambiswa nebhatiri rakavakwa.

Saka, iyo yese system ine yakasimba anti-kukuvara kugona

Weak

1. Hardware yakaoma

2. Kushanda kwehurongwa kunoenderana newaya links.

3. Kana zvivakwa zvaparadzwa nenjodzi. Iyo sisitimu haishande zvakajairika.

saka, kugona kwayo kwekudzivirira kukanganisa hakuna simba.

Switch 1. Hapana chinodiwa wired switch
2. Inotora mhepo isina waya switch
Kuchinja kunodiwa
Coverage Nekuti iyo base chiteshi inotora girazi tekinoroji, iyo rf inopfuudzwa. Naizvozvo, iyo sisitimu ine kuvharika kuri nani kune mashoma mapofu makwapa Mamwe mapofu
Centerless ad hoc network Ehe Ehe
Kuwedzera simba Wedzera huwandu pasina muganhu Kuwedzera kushoma: Kunoganhurwa nehuwandu kana zvimwe zvinhu
Hardware Chimiro chakareruka, uremu huremu uye hukuru hudiki Complex chimiro uye hukuru hukuru
Sensitive -126dBm DMR: -120dbm
Hot backup Multiple base zviteshi zvinogona kushandiswa zvakafanana kune kuwirirana inopisa backup Kwete kutsigira zvakananga kuita inopisa backup
Kukurumidza kutumira Ehe No
