Dau teteva vagauna na FHSS na veititi ni cakacaka me baleta na isema ni veitaratara ni vidio kei na iciqociqo
How does FHSS work on the drone wireless video transmitter and receiver?
FHSS is an automatic frequency modulation technology. We widely used FHSS in wireless video data transmission of drones. Because the drone’s wireless link is often subject to signal interference.
Ena vidio oqo, this frequency point shows the current signal strength.
Na 1365 we see is the current signal working frequency point of our wireless transmission equipment.
Why does this frequency go here?
Because there are other signals on the right that are interfering. It will run automatically.
If the signal receives interference again, it runs away again, choosing the frequency with the least interference.
This process is meant to avoid interference. We also call it the FHSS function.

Q1: What is the FHSS Frequency-hopping spread spectrum?
A1: Tete ni ivakarau ni bula (MSTS) is a method of transmitting radio signals that involves rapidly changing the carrier frequency among a wide range of frequencies.
FHSS will occur automatically on both the transmitter and receiver at the same time. FHSS is used to prevent eavesdropping and interference on the long-range wireless video transmitter and receiver. When the current working frequency is jammed or interfered with, the transmitter and receiver disconnect and hop to the next available frequency to reconnect.
Q2: Why do you need the FHSS function?
A2:
1. Because the signal hops to a different frequency band, FHSS signals are highly resistant to narrow-band interference.
2. If the frequency-hopping pattern is unknown, signals are difficult to intercept.
3. Jamming is also difficult if the pattern is unknown; if the spreading sequence is unknown, the signal can only be jammed for a single hopping period.
4. With minimal mutual interference, FHSS transmissions can share a frequency band with many types of conventional transmissions. FHSS signals interfere in narrow-band communications and vice versa.
Q3: How to set the FHSS at your wireless video data transmitter and receiver?
A3: At the web manager UI, please choose the advance page, you can see the above picture.

Q4: 7 tips you should know before you choose a wireless video transmitter and receiver with FHSS function.
A4:
1. TX900B-2W supports the frequency range is 1420~1530MHz, ka sa 110Mb na bandwidth me vakayagataki.
2. Sa rawa vua na kasitama me tuvanaka na bandwidth cakacaka me 1.4M/3M/5M/10M/20MHz (Ia, 1.4M/3MHz may not be suited for video transmitting). Sa na qai rawa ni cakacaka na TX900B-2W ena ivakarau ni FHSS (Tete ni ivakarau ni bula) and the system will automatically select the central working frequency and may do frequency hopping (ena maliwa ni 1420 ~ 1530MHz) ena gauna ni nona cakacaka.
3. Sa rawa talega vei ira na kasitama me ra tuvanaka me ra vakayagataka na sala ni vakawasoma ena 1420 taucoko ~ 1530MHz ka tuvanaka na misini me cakacaka talega ena sala tudei ni wasoma.
4. TX900B-2W supports the longest distance at 22km.
Vakavo ga na ivakarau ni kena tokoni ka yawa sara, the physical appearance, veisemati, UI, operation, kei na so tale, the TX900B-2W is the same as the existing TX900B-15km-2W.
5. TX900B-2W only support a frequency range is 1420~1530MHz, it does not support 800MHz and 2.4GHz frequency range.
6. There are two versions, TX900B-2W-15km, and TX900B-2W-22km.
7. As the TX900B-2W frequency range is 110Mb, so if you config the working bandwidth as 10Mb, then you will get 11 points to hopping.
T5: What is the working principle of your FHSS?
Our wireless video transceiver adopts intelligent frequency selection-interference avoidance.
Intelligent frequency selection (interference avoidance) technology is a new anti-interference technology, which can effectively avoid interference and maximize the reliability and stability of wireless transmission.
The key to our unique intelligent frequency selection (interference avoidance) technology lies in the three major processes of interference detection, decision-making, and switching execution. Interference detection refers to real-time detection of interference and background noise at each frequency point during normal communication, so as to provide basic support for decision-making. The decision-making is completed independently by each node, and the optimal frequency is selected based on the criterion of optimizing its own receiving performance. The point is used as the receiving frequency point; the switching execution occurs after the decision selects a new optimal frequency point, and the switching process will not cause data loss, ensuring stable and continuous data transmission.
Our unique intelligent frequency selection (disturbance avoidance) technology enables each node to independently and dynamically select different optimal frequency points for different frequency networking, so as to optimize the overall network performance and effectively avoid interference.
Yalovinaka dikeva na iyaloyalo e ra, the blue area is the effective signal, kei na the red line is interference. 
T6: Do you have a video data link as per the below requirement?
The required distance is 50 kilomita, kei na kena dau vagauna na tekinolaji (jumping over 1,000 times in one second), ideally above 6Ghz (others can be considered, the most important thing is frequency hopping technology), and it is also necessary to transmit data, Vidio, and protect the remote control channel, preferably A set of data links (transmitter + iciqociqo + ivana ni walesi o) using frequency hopping technology (MSTS)
iVcan Reply: Sega, The frequency is only 1.4G, the working frequency for 6Ghz needs custom development.
T7: Do you have any optional model to support the FHSS Frequency-hopping spread spectrum?
In the below picture, you can see that there are 12 points frequency ready for FHSS.
