COFDM Transceiver

Eaha te COFDM Transceiver?

COFDM Transceiver o te hoê ïa anairaa matini o te nehenehe e farii e e hapono i te mau haamaramaramaraa e te video. Te taata e farii i te reira, e hoê noa iho rave'a i te hono, e paturu noa te reira i te haaparareraa mana'o-ore-hia.

I roto i te COFDM transceiver, te vai ra e piti anairaa COFDM transmitters e te feia farii, o te hapono i te mau arata'iraa taa ê ia nehenehe i te hoê matini ia farii e ia hapono i te mau haamaramaramaraa, hio, e te faaroo i ni'a i te tahi atu matini haruharu. No reira, ua riro te COFDM Transceive ei hono no te haponoraa e piti tuhaa.

Both COFDM transceiver has ethernet IP RJ45 connectors, e au te reira i te hoê upe'a ite-ore-hia. E turu te reira i te tu'atiraa i te hoê pata hoho'a IP e e turu atoa oia i te tu'atiraa e piti matini roro uira atea, te turu nei oia i te raveraa i te ohipa i roto i te Windows OS CMD, o te faaite mai i te mau mana'o no ni'a i te taime opereraa.

Nahea ia ma'iti i te hoê COFDM Transceiver?

Ia ma'iti ana'e tatou i te hoê COFDM, e ti'a paha ia outou ia hi'opo'a e rave rahi mau tumu:

Taime

Te faatae nei te mau taata hoo e te mau taata farii i te hoê â arata'iraa, no reira, hoê ana'e taime e ti'a ia hi'opo'ahia. TE MAU NOTA, no reira, e ti'a ia hi'opo'ahia e piti mana'o. E tia ia faataa - ê - hia na anairaa e piti no te ape i te mau haafifiraa. No te faaore i te huenane e no te ape i te mau haafifiraa, e mea titau-atoa-hia ia feruri i te tuu atu i te hoê titi'a are.

No roto mai te mau hoho'a taa ê i te 170 no te 860 MHz. Ei hioraa, ma'iti i te 300Mhz no te uplink frequency e 600Mhz no te tai'oraa i raro i te fenua.

E ti'a atoa i te ma'itiraa taa ê ia hi'opo'a i te huru o te tupuraa o te fenua iho. Mai te mea e, te vai ra te DVB-T e aore râ, te DVB-T2 i roto i te afata teata o te fenua iho, e mea titau-atoa-hia ia ape i te mau mata'i roro uira tei ma'itihia e te matini roro uira.

I muri a'e i te ma'itiraa i te pinepineraa no te faataeraa, e ti'a atoa i te taata farii ia tape'ahia i roto i te hoê â anairaa e tae atu i te haponoraa e te fariiraa.

Bandwidth

Taa ê atu i te afata teata roro uira, tei 6, 7, e 8Mhz, e nehenehe te pǔpǔ o te COFDM transceiver e faaohipahia, mai te 2MHZ e 4MHz.

Te mana Amplifier

Te tao'a uira e faahitihia ra i ǒ nei, o te hoê ïa matini o te nehenehe e faarahi i te puai o te tapao o te COFDM no roto mai i te matini haapurororaa, o te nehenehe e haamaitai atu â i te huru e te haaparareraa mana'o.
E mea ti'a i te taata aravihi i te pae no te uira o te COFDM ia tape'a noa i te reni afaro e te aravihi. Te rahiraa o te taime, a ma'iti i te puai tano ia au i te atearaa e ti'a ia oe ia faatae atu. Teie i muri nei te hoê tabula rata i rotopu i te atearaa e te uira no ta outou faahororaa.

Tapao itea

Te auraa o te parau ra Sensitivit, o te aravihi ïa o te hoê matini haapurororaa video aita e niuniu paraparau no te faatae i te mau tapao paruparu e no te farii i te reira e te taata e farii ra i te reira.

E faito - pinepine - hia te tâu'a - ore - raa i roto i te mau décibels (dB) e aore râ, décibel milliwatts (dBm) e te faahoho'a ra te reira i te faito iti roa ' ' e o te puai tapao ta te hoê taata e nehenehe e ite e e rave.

Rahi noa'tu te ino, maitai a'e te ha'utiraa e te haapurororaa i te mau video aita e niuniu paraparau.

Te mau hotu o te COFDM Transceiver

E piti COFDM e ohipa ra mai te 170Mhz e tae atu i te 860Mhz. E tia i te mau ravea i maitihia ia faataa ê roa ia ratou no te ape i te mau haafifiraa i rotopu i te tahi e te tahi.
I roto i te faaohiparaa mau, e mea titauhia te reira no te tuu atu i roto i te hoê buka iti, Titi'a, e antenna e tu'ati ra i te pinepineraa o te ohipa.

Te Puohu o te COFDM Transceiver

COFDM transceiver, ua pii-atoa-hia o Bidirectional COFDM Ethernet Radio, Bidirectional Wireless Ethernet Bridge.

Can you customize the frequency 340Mhz and 554Mhz COFDM transceiver for me?

E.

Why the two filters per transciever are used? One filter for RX and one PA for TX are enough?

1. Filters are added to avoid interfering with or being interfered with by other devices.
   Please test the transceiver first without connecting the filter.
2. The transmitter adds a filter because it has a power amplifier, It will emit a strong signal to avoid interfering with other equipment on the plane.
3. The receiver add filter allows the receiver to receive only the desired signal and avoid clutter, and that signal sensitivity is improved.
4. You need to connect the filter when the transmission distance is not far or the signal strength is very poor in the test.
5. If the transmitter does not add a filter, it may interfere with the flight control or the power battery. Some customers have encountered this phenomenon before, and the filter has solved the problem.
6. You take the sample now and suggest buying it together when you test it and need the filter, and it will take more time and freight to deliver it.
