M'manja PTT MESH Radio Base Station

Chitsanzo: Defensor-TS1

TS1 ndiye Siteshoni yapamanja yoyamba yapamanja ya PTT MESH Radio Base Station yokhala ndi kulemera kwa 560g ndi chophimba cha LCD cha 1.7inch.

Mawayilesi angapo a PTT Mesh amatha kulumikizana mwachindunji, ndikupanga maukonde akulu komanso akanthawi (ad hoc) opanda zida zakunja monga nsanja zama cell kapena masiteshoni.

Ogwiritsa ntchito akanikizani batani la Push-to-Talk, ndiye kuti mawu kapena zidziwitso zidzatumizidwa kudzera pa netiweki ya mesh pogwiritsa ntchito njira yomwe ilipo. TS1 iliyonse imagwira ntchito ngati station station, repeater and manet terminal radio kutumiza ndi kubwereza mawu/data kuchokera ku chipangizo china kupita ku china mpaka itafika komwe ikupita.

Ndi mphamvu yotumizira ya 2w-25w(yosinthika), mawayilesi angapo a m'manja a MANET amatha kuphimba dera lalikulu ndi kulumikizana kwa ma hop ambiri. Ndipo kudumpha kulikonse kuli pafupifupi 2km-8km.

Wayilesi ya TS1 yogwirizira m'manja ya PTT manet ndi yaying'ono ndipo imatha kugwidwa pamanja kapena kuyikidwa pamapewa, kumbuyo kapena m'chiuno ndi kachikwama kachikopa.

TS1 ili ndi batire ya lithiamu yomwe imatha kutha kwa maola 31 ndipo ngati igwira ntchito ndi banki yake yamagetsi, moyo wa batri ukhoza kukhala 120hours.

Mawonekedwe

Kulankhulana Kwanthawi yayitali

● TS1 imapangidwa ndikupangidwa kutengera ad-hoc network imathandizira 6hops.
● Anthu angapo amakhala ndi ma wayilesi a TS1 manet kuti apange makina olumikizirana ma hop ambiri ndipo hop iliyonse imatha kufika 2-8km.
● Chigawo chimodzi cha TS1 chinayikidwa pa 1F, nyumba yonse kuyambira -2F mpaka 80F ikhoza kutsekedwa (kupatula kanyumba ka elevator).

Kulumikizana kwa Cross Platform

● IWAVE imapereka njira yonse ya mawailesi a manet kuphatikizapo malo oyendetsera malo ndi malo otumizira, ma solar powered base station, ma radio terminals, airborne MANET base station ndi manpack base station kuti akwaniritse zochitika zosiyanasiyana zogwiritsira ntchito.
● TS1 imatha kulumikizana bwino ndi mawayilesi onse a MANET a IWAVE, malo olamulira ndi masiteshoni oyambira omwe amalola ogwiritsa ntchito pamtunda kuti azilumikizana ndi magalimoto osayendetsedwa ndi anthu, ma UAV, katundu wapanyanja ndi malo opangira zida kuti apange kulumikizana kolimba.

Kodi PTT Mesh Radio Imagwira Ntchito Motani?
●Multiple TS1 opanda zingwe kulankhulana wina ndi mzake kupanga kwakanthawi ndi multi hop opanda zingwe netiweki.
● TS1 iliyonse imagwira ntchito ngati siteshoni yoyambira, yobwerezabwereza komanso yotumizira mawayilesi ndikubwereza mawu/data kuchokera ku chipangizo china kupita ku china mpaka itafika komwe ikupita.
● Ogwiritsa asindikiza batani Push-to-Talk, ndiye mawu kapena deta idzatumizidwa kudzera pa intaneti ya ad-hoc pogwiritsa ntchito njira yabwino kwambiri yomwe ilipo.
● Netiweki ya mauna ndiyodalirika kwambiri chifukwa ngati njira imodzi yatsekedwa kapena chipangizo chili kutali ndi intaneti, mawu/data ikhoza kutumizidwa kunjira ina.

Ad-Hoc Repeater&Radiyo

● Kudzipanga nokha, kugawidwa kwapadera ndi maukonde ambiri opangidwa ndi ma node ambiri omwe ali ndi mphamvu zodutsa malire zomwe zimakhazikitsa maulumikizi popanda waya;
● Nambala ya node ya TS1 ilibe malire, ogwiritsa ntchito angagwiritse ntchito TS1 ochuluka momwe akufunira.
●Dynamic network, lowani mwaufulu kapena kuchoka pakuyenda; kusintha kwa network topology
motero
●2 hops 2 channels, 4 hop 1 channel via single carrier(12.5kHz) (1Hop=1time relay; channel iliyonse imathandizira kuyimba kwapayekha ndi gulu, kuyimba konse, kusokoneza koyambirira)
●2H3C,3H2C,6H1C kudzera pa chonyamulira chimodzi(25kHz)
●Kuchedwa kwanthawi kosakwana 30ms mu single hop

Ad-hoc Network Radio

● Kulunzanitsa koloko ndi netiweki ndi nthawi ya GPS
● Sankhani basi mphamvu ya siginecha yoyambira
●Kungoyendayenda mopanda msoko
● Imathandizira kuyimba kwa anthu payekha kapena pagulu, kuyimba kulikonse, kusokoneza kofunikira
● Njira 2-4 zamagalimoto kudzera pa chonyamula m'modzi (12.5kHz)
● Njira 2-6 zamagalimoto kudzera pa chonyamula m'modzi (25kHz)

Chitetezo Chaumwini

●Munthu pansi
● Batani lazadzidzi la chenjezo komanso kumvera ambulansi
● lnitiate kuitana kumalo olamulira
●Kusonyeza mtunda wa woimbirayo ndi kumene akuimbira foni
●Kusaka m'nyumba ndi malo omwe wailesi ikusowa
● Njira yamphamvu ya 20W ikhoza kutsegulidwa pakafunsidwa pakachitika ngozi

Kugwiritsa ntchito

● Kwa magulu oyankha mwanzeru, kulankhulana kosalala ndi kodalirika ndikofunikira.
●Zochitika zazikulu zikachitika, magulu amayenera kugwira ntchito m'malo ovuta monga mapiri, nkhalango, malo oimikapo magalimoto apansi panthaka, tunnel, m'nyumba ndi zipinda zapansi za nyumba zamatawuni komwe mawayilesi a DMR/LMR kapena ma cellular kulibe, ogwiritsa ntchito amatenga TS1 amatha kuyatsa mwachangu ndi amalankhulana okha kwa nthawi yayitali kuposa ma analogi achikhalidwe kapena mawayilesi a digito.
