Cathetan

Nalika pemancar COFDM-905T lan panrima COFDM-905T mbentuk sistem transmisi video nirkabel point-to-point, indikator tundha video:
Telung pratondho wektu tundha video, bit rate video, lan tingkat antarmuka udhara minangka pengaruh lan saling ngendhaleni. Nalika tingkat antarmuka online luwih saka 5 kaping tingkat kode video, wektu tundha video minimal. Ing kasus iki, test nyata iku wektu tundha video bab 60 ms nalika kode dikirim ing 720P@60, lan wektu tundha video babagan 130 ms ing 1080P@60. Wektu tundha nuduhake wektu tundha saka input video HDMI ing mburi ngirim menyang output video HDMI ing mburi panampa., ora kalebu wektu tundha kamera ngarep mburi mburi transmisi (kita diukur wektu tundha saka kamera SLR account ing babagan 70 ms, lan wektu tundha saka merek misuwur olahraga kamera ing babagan 130 ms). Kanggo umume skenario aplikasi, wektu tundha video disetel kanggo bab 200ms minangka standar.

Nalika pemancar COFDM-905T lan panrima COFDM-905R mbentuk sistem transmisi video nirkabel point-to-point, jarak transmisi punika:
Jarak transmisi nirkabel ana gandhengane karo akeh faktor kayata lingkungan tes, interferensi elektromagnetik sekitar, kahanan occlusion, asor hawa, frekuensi kerja, bandwidth nirkabel, lan ngirim lan nampa antena. Asil tes nyata: tes pelanggan, pesawat tanpa awak dipasang ST100 pemancar kanggo fly babagan 100 dhuwur meter, nyetel bandwidth nirkabel 4M QPSK, 700frekuensi operasi tengah MHz, 1W ngirim daya, antena pemancar 3dBi watara, Nampa gain antena serat kaca kaping pindho babagan 10dBi, jarak nganti 16 km (video lancar); test dalan kita dhewe ing Shenzhen, pungkasan peluncuran ing flyover, antena selang biasa (babagan gain 3dBi), 340peluncuran MHz, Bandwidth QPSK 8M, antena fiberglass ing mburi nampa, lan antena Yagi, babagan 2.2 meter dhuwur ing kutub, 2.2 kilometer adoh, video dhuwur-definisi Gamelan, jumlah cilik saka bangunan dhuwur antarane pemancar lan panrima, dalan visual babagan 20 derajat mlengkung. Amarga watesan kondisional, ora ana tes dalan maneh.
