Modulu di trasmissione trasparente Ethernet wireless COFDM 100M bps RJ45 FDD trasmettitore è ricevitore di dati video

Mini COFDM wireless Ethernet transparent transmission module 100M bps RJ45 FDD video data transmitter and receiver for UDP IP camera

I MUVRINI

1. This is a broadband cofdm wireless video data transmission module. Both the transmitter and receiver modules have an RJ45 network and UART data and control interface.
2. The network port on the transmitter can be connected to the IP camera as the video source for wireless transmission, and it can also be connected to the data source of the network port, which is transmitted to the receiving module through COFDM technology. The receiver also has an RJ45 network and data UART control port, and it supports UDP playback on the PC.
3. The frequency can be modified through the UART serial port, or one-way data transmission can be added to realize the requirement of remote frequency modification without powering off to restart.
4. There are two RF antennas on this transceiver module, one is TX and the other is RX, which can realize two-way transmission of video and data. Two different frequency ranges need to be set, and BPF filters are used to filter clutter and avoid mutual interference.
5. This model can run the CMD Ping command and get a response. (video on youtube)
6. This is adopted by FDD technology.
7. The default working frequency is 340Mhz and 590Mhz. (Other frequencies can be adjustable from 170~860Mhz)
8. It does not include any power amplifier.

channel size parameter calculation method reference

The maximum channel capacity of the system can be calculated using the following formula:

Rmax=6.75 x b x FEC x (188/204) X (1/(1+GD)) X (BW/8)

Rmax: The maximum capacity of the channel(Mb/s)

B: Coupling wave ratio function, QPSK orab=2, 16Qam orab=4，64Qamorab=6

F fec: internal error correction code rate(1/2, 2/3, 3/4, 5/6, 7/8)

GD: tretu guardia1/4, 1/8, 1/16, 1/32

BW: Bandwidth in M

According to the above formula, the maximum capacity of the channel can be calculated under a few parameters. The following table shows the information capacity under 8M bandwidth. The system will automatically calculate the size of the encoded output stream according to the set channel parameters so that the size of the output stream is not greater than the maximum capacity of the channel.

Ppi

On the L25 position on the board (on the side of U13, the position is empty when leaving the factory) un 0603 inductance can be added to increase the output power. The added inductance value can refer to in the figure below.

Precautions for order customization

1. FDD, as a transparent transmission module of peer-to-peer network with network port RJ45. It comes with two COFDM modules with different frequencies. The default frequency is 340Mhz and 590Mhz, customers can modify it through the parameter configuration board.
2. According to the default frequency of 340Mhz and 590MHz, the delivered accessories will contain the antenna of the default frequency. If you want to modify the frequency yourself, please let us know if we need to provide an antenna for the matching frequency.
3. With the parameter adjust menu board and screen, your client needs one to modify the parameter.
   When the parameters are adjusted well, they can be taken down. Except for your order quantity, please tell me how many pcs of the menu board and screen you need.
