Yintoni i-DMR
I-Digital Mobile Radio (i-DMR) ngumgangatho wamazwe ngamazwe kwiirediyo ezinezindlela-mbini ezisasaza ilizwi kunye nedatha kuthungelwano lwerediyo olungelulo ololuntu. I-European Telecommunications Standards Institute (ETSI) yenza umgangatho kwi-2005 ukujongana neemarike zorhwebo. Umgangatho uhlaziywe amaxesha amaninzi ukususela ekudalweni kwawo.
Yintoni inkqubo ye-Ad-hoc Network
Inethiwekhi ye-ad hoc yinethiwekhi yesikhashana, engenazingcingo evumela izixhobo ukuba zidibanise kwaye zinxibelelane ngaphandle kwe-router ephakathi okanye i-server.Kwaziwa ngokuba yi-mobile ad hoc network (MANET), yinethiwekhi yokuzimela yezixhobo eziphathwayo ezinokuthi zinxibelelane ngaphandle kokuxhomekeka kwisiseko esele sikhona okanye ulawulo oluphakathi. Inethiwekhi yenziwa ngokuguquguqukayo njengoko izixhobo zingena kuluhlu lomnye nomnye, zivumela ukuba zitshintshiselane ngedatha yoontanga-kuontanga.
I-DMR ithandwa kakhulu kwiirediyo eziphathwayo zonxibelelwano oluvakalayo. Kule theyibhile ilandelayo, Ngokweendlela zokunxibelelana, senze uthelekiso phakathi kwe-IWAVE Ad-hoc network system kunye ne-DMR.
| IWAVE Ad-hoc System | I-DMR | |
| Ikhonkco elineentambo | Akukho mfuneko | Kufuneka |
| Qalisa umnxeba | Ngokukhawuleza njengee-walkie-talkies eziqhelekileyo | Umnxeba uqalwa ngumjelo wolawulo |
| Ubuchule bokuchasana nomonakalo | Yomelele 1. Isistim ayixhomekekanga kulo naliphi na ikhonkco elineentambo okanye iziseko ezingundoqo. 2. Uqhagamshelwano phakathi kwesixhobo ngasinye alunacingo. 3. Isixhobo ngasinye sinikwe amandla ngebhetri eyakhelweyo. Ngoko ke, yonke le nkqubo inamandla okuthintela umonakalo | Ubuthathaka 1. I-hardware inzima 2. Ukusebenza kwesistim kuxhomekeke kumakhonkco aneentambo. 3. Nje ukuba iziseko zophuhliso zitshatyalaliswe yintlekele. Inkqubo ayiyi kusebenza ngokuqhelekileyo. ke, isakhono sayo sokuchasa umonakalo sibuthathaka. |
| Tshintsha | 1. Akukho mfuneko yokutshintsha ucingo 2. Yamkela iswitshi yomoya engenazingcingo | Ukutshintsha kuyafuneka |
| Ukhuseleko | Ngenxa yokuba isikhululo esisisiseko samkela itekhnoloji yokujonga isipili, i-rf isasazwe. Ke ngoko, inkqubo inokhuselo olungcono kunye neendawo ezimbalwa ezingaboniyo | Iindawo ezininzi ezingaboniyo |
| Inethiwekhi ye-ad hoc engenaziko | Ewe | Ewe |
| Ukwandiswa kwamandla | Yandisa umthamo ngaphandle komda | Ulwandiso olulinganiselweyo: Unyinwa ngamaxesha amaninzi okanye ezinye izinto |
| Hardware | Isakhiwo esilula, ubunzima obulula kunye nobukhulu obuncinci | Ubume obuyinkimbinkimbi kunye nobukhulu obukhulu |
| Inovakalelo | -126dBm | I-DMR: -120dbm |
| Backup eshushu | Izikhululo ezininzi ezisisiseko zingasetyenziswa ngokunxuseneyo ukuze zigcinwe zishushu | Ayixhasi ukwenza ugcino olushushu ngokuthe ngqo |
| Ukuthunyelwa ngokukhawuleza | Ewe | No |
