| impendulo: Ukuba ufaka PA (booster), wena awukwazi; Ukuba awufuni PA (booster), ke awukwazi (PA nguye izinto, ukuba utshintsha indawo isicwangciso, izinto kumele adjustable) |
| umbuzo: Yintoni na ixabiso amaza ubuninzi ukuba sikwazi ukuchaza? |
| impendulo: 900MHz, ezinendingeko enkulu, Nceda ukhethe COFDM-902T |
| umbuzo: Ukuba isiqwenga Beach 300-900 Ndiza kukuxelela ngokuchanekileyo 4 enxibelelanisayo ukuchaza kum, mna nda uya kufuna izinga data njalo 10 mbps, 16QAM kwezwi ku, FEC 1/2 kunye noKhuseleko lwexesha 1/32. le encoding 4.2.2 xa oku kunokwenzeka endaweni yokusebenzisa 4.2.0, 200 mitha (NLOS) Akukho umgca kwamehlo kunye 500 mitha (THE) Umgca we Phambi. RF amandla 500 MW, khumbula ukuba, ireyithi yedatha KUFUNEKA abekwe (akukho eziguquguqukayo) ukuba 10 mbps, zama esi sicwangciso kwaye makhe uyazi ukuba isebenza njani: (bhetele ukuba ungandithumelela ividiyo emfutshane erekhodiweyo ngokuthe ngqo kwimveliso ye-hdmi yomamkeli- UNGAYENZI Ngokudubula ESWENI screen! Ubuncinane sidinga 27dBm |
| impendulo: kulungile, singenza phezu isampuli xa kuqinisekiswa. |
| umbuzo: Ingaba unayo ikhamera, I Ungafumana ividiyo kwi computer yam? |
| impendulo: yes, Nceda ujonge elinye iphepha. COFDM receiver USB imidlalo yokuzonwabisa. |
Ingaba unayo imibuzo, Nceda ucofe apha buza umbuzo.
