He aha ka DMR
ʻO Digital Mobile Radio (DMR) kahi maʻamau honua no nā lekiō ʻelua ala e hoʻouna i ka leo a me ka ʻikepili ma nā pūnaewele lekiō ʻole. Ua hoʻokumu ka European Telecommunications Standards Institute (ETSI) i ka maʻamau ma 2005 e hoʻoponopono i nā mākeke kalepa. Ua hoʻonui ʻia ka maʻamau i nā manawa he nui mai kona hana ʻana.
He aha ka ʻōnaehana Ad-hoc Network
ʻO kahi pūnaewele ad hoc kahi ʻupena uʻi liʻiliʻi e hiki ai i nā mea hana ke hoʻopili a kamaʻilio me ka ʻole o kahi alalai kikowaena a i ʻole server. e hilinaʻi ana i kahi ʻoihana i loaʻa mua a i ʻole kahi hoʻokele kikowaena. Hoʻokumu ʻia ka pūnaewele me ka ikaika i ka hele ʻana o nā mea i loko o ka laulā o kekahi, e ʻae iā lākou e hoʻololi i ka ʻikepili peer-to-peer.
He lekiō kelepona kaulana loa ʻo DMR no ʻelua kamaʻilio leo. Ma ka papa aʻe, Ma ke ʻano o nā ʻano hana pūnaewele, ua hoʻohālikelike mākou ma waena o IWAVE Ad-hoc network system a me DMR.

| loulou uea | ʻAʻole pono | Pono |
| E hoʻomaka i kahi kelepona | E like me ka wikiwiki e like me nā walkie-talkie mau | Hoʻomaka ʻia ke kelepona e ke ala hoʻomalu |
| Hiki ke kū'ē i ka pōʻino | Ikaika 1. ʻAʻole hilinaʻi ka ʻōnaehana i kekahi loulou uea a i ʻole nā mea hana paʻa. 2. He uwea ka pilina ma waena o kēlā me kēia mea. 3. Hoʻohana ʻia kēlā me kēia mea hana e ka pākaukau i kūkulu ʻia. No laila, loaʻa i ka ʻōnaehana holoʻokoʻa ka ikaika anti-pōʻino | Nawaliwali 1. He paʻakikī ka lako 2. Pili ka hana o ka ʻōnaehana ma nā loulou uea. 3. I ka wā i luku ʻia ai ka ʻoihana e ka pōʻino. ʻAʻole e hana maʻamau ka ʻōnaehana. no laila, nāwaliwali kona mana anti-damage. |
