What is a military cofdm wireless signal transmitter?
A military COFDM wireless signal transmitter is a device that can send and receive audio and data signals using the COFDM (Hoʻohui ʻia ʻo Orthogonal Frequency Division Multiplexing) digital modulation technique. COFDM is a similar technology to DVB-T Europe digital tv standard, which can highly effectively compress the video and audio in TS stream by encoder and modulator, and at the receiver with decoder and demodulator chipset, it can perfectly get the real living video, Audio, and data from the transmitter to the receiver.
This approach makes the signal more resistant to interference, halulu, and fading, kupono no na hana koa.

Military cofdm wireless signal transmitter Types
makepono: No ke kumu hoʻohālike loa, manaʻo mākou ua kau ʻia kekahi mau transmitters ma nā drones, a hiki iā lākou ke kuʻi i nā lāʻau a i ʻole nā mea keakea ʻē aʻe i kēlā me kēia manawa a hāʻule lākou. No ka mea, ua maʻalahi lākou, hiki ke kūʻai ʻia i ka nui a hoʻohana ʻia e like me nā mea hoʻopau. Ina nalowale, hiki ke pani ia lakou. Hiki ke hoʻoponopono ʻia ka mea hoʻokipa me nā transmitters ʻē aʻe no ka hoʻohana mau ʻana. COFDM-912T, E noi i nā kikoʻī e pili ana i kēia kükohu. 
HDMI 1080p: Kākoʻo ke kumu hoʻohālike haʻahaʻa ma luna nei i ka hoʻonā 720P a me ka hoʻokomo kiʻi kiʻi kiʻi CVBS composite. Inā loaʻa iā ʻoe nā koi kiʻekiʻe no ka hoʻonā wikiō, ʻōlelo ʻia ʻoe i ka COFDM-908T me ka hoʻokomo HDMI a me ka hoʻopuka e kākoʻo i ka 1080P. COFDM-908T, E noi i nā kikoʻī e pili ana i kēia kükohu.
Latency haʻahaʻa: No kekahi mau UAV nui a nui, ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana o ka mokulele, a pono e hana ʻia ka transmitter me ka latency ultra-low. ʻO ka lohi o nā ʻōnaehana hoʻoili wikiō maʻamau e hiki i 200 ~ 400 milliseconds, akā, hiki i ka ʻōnaehana hoʻoiho wikiō uʻi haʻahaʻa haʻahaʻa ke hiki i kahi 30 ~ 40 milliseconds kupaianaha., He kūpono loa ia no nā drones kiʻekiʻe a me ke kumu kūʻai nui e hōʻoia i hiki ke ʻike i nā pilikia i ka manawa a hana i nā hoʻoponopono kūpono.. Vcan1729, E noi i nā kikoʻī e pili ana i kēia kükohu.
HDMI + ʻO CVBS nā kāmeʻa wikiō ʻelua: I kekahi mau drones a i ʻole nā kūlana palekana ʻē aʻe, ua hoʻokomo ʻia ʻelua kamera, e koi ana i kā mākou transmitter e hiki ke hoʻouna i ʻelua wikiō i ka manawa like. No nā mea kūʻai me kēia pono, hiki iā ʻoe ke koho i kā mākou Vcan1726., E noi i nā kikoʻī e pili ana i kēia kükohu.
Hoʻopuka ʻo Ethernet RTSP i ke kamepiula: Pono kekahi mau mea kūʻai aku ʻaʻole hiki i ka mea hoʻokipa ke hoʻopuka i nā kiʻi i kahi nānā maʻamau akā hoʻopuka pū kekahi i nā kiʻi i kahi kamepiula i ka manawa maoli.. Ma keia hihia, pono ka mea hoʻokipa e loaʻa i kahi puka puka pūnaewele e kākoʻo ana i nā protocols ONVIF a me RTSP. Hiki iā ʻoe ke pāʻani i ke wikiō ola o ka mea hoʻolaha me ka hoʻohana ʻana i kahi mea pāʻani VLC. Vcan1726, E noi i nā kikoʻī e pili ana i kēia kükohu.
Hoʻolaha hōʻailona / Mea hana hou / Hoʻonui: Ma kekahi mau noi kūikawā, e like me na hale, mauna, a i ʻole nā lāʻau e ālai ana i ka hōʻailona, hiki iā mākou ke kau i nā relays i waenakonu o nā mea pale e hoʻonui i ka mamao o ka hoʻouna ʻana a hoʻonui i ka ikaika hōʻailona o ka hoʻouna.. Vcan 1870, E noi i nā kikoʻī e pili ana i kēia kükohu.
Hoʻonā no ka noi transceiver ʻelua ala: Ua ʻike nā kānaka a pau ʻo CFODM kahi ʻōnaehana hoʻoili ala hoʻokahi e hiki ke hoʻouna i ke wikiō, Audio, and data from the transmitter to the receiver, akā ʻaʻole hiki ke hāʻawi i ka hōʻailona hōʻailona a i ʻole nā manaʻo pane. Eia naʻe, i mea e hoʻoponopono ai i nā pono o ka mea kūʻai aku no ka lawe ʻana i ʻelua ala, Hiki i nā ʻenekini ke hana i ʻelua pūʻulu o nā ʻōnaehana transceiver COFDM i hoʻokahi, no laila, loaʻa i ka transmitter ka hana o ka mea hoʻokipa, a o ka mea hookipa no hoi ka hana o ka transmitter. ʻO kēia ka transceiver COFDM. Vcan 1886, E noi i nā kikoʻī e pili ana i kēia kükohu.
Hana hoʻolaha UDP: Vcan1816, E noi i nā kikoʻī e pili ana i kēia kükohu.
