Q1: What is the FHSS Frequency-hopping spread spectrum?

A1: Frequency-hopping spread spectrum (FHSS) 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. https://i0.wp.com/ivcan.com/wp-content/uploads/2022/02/UI-Advance.webp

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, and there is 110Mb bandwidth to use. 2. The customer can set the working bandwidth as 1.4M/3M/5M/10M/20MHz (However, 1.4M/3MHz may not be suited for video transmitting). Then TX900B-2W can work in FHSS mode (Frequency-hopping spread spectrum) and the system will automatically select the central working frequency and may do frequency hopping (between 1420~1530MHz) during its working. 3. Customers can also plan to use the frequency channels in the whole 1420~1530MHz and set the device to work in the fixed frequency channels too. 4. TX900B-2W supports the longest distance at 22km. Except for the frequency range supported and the longest distance, the physical appearance, interface, UI, operation, and so on, 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.

Q5: 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. Please check the below picture, the blue area is the effective signal, and the red line is interference.

FHSS Frequency-hopping kis spectrum rau wireless yees duab cov ntaub ntawv txuas

FHSS ua hauj lwm rau lub drone wireless yees duab transmitter thiab receiver?

FHSS yog ib qho kev modulation tshuab. Peb lug siv FHSS hauv wireless yees duab transmission ntawm drones. Vim hais tias cov drone wireless txuas yog feem ntau yuav raug teeb liab cuam tshuam.

Nyob rau hauv no yees duab, No zaus taw tes qhia tau hais tias lub teeb liab tam sim no lub zog.

Tus 1365 Peb pom yog lub teeb liab ua hauj lwm frequency taw tes ntawm peb wireless transmission khoom.

Vim li cas qhov no zaus mus ntawm no?

Vim hais tias muaj lwm yam teeb liab rau sab xis uas yog interfering. Nws yuav khiav automatically.

Yog hais tias lub teeb liab tau cuam tshuam dua, Nws sau tseg dua, xaiv qhov sib npaug nrog cov kev cuam tshuam.

Txoj kev no yog meant kom tsis txhob cuam tshuam. Peb kuj hu nws tus FHSS muaj nuj nqi.

Q1: Tus FHSS Frequency-hopping kis spectrum?

FHSS yuav tshwm sim rau ob lub transmitter thiab receiver tib lub sijhawm. FHSS siv los tiv thaiv eavesdropping thiab cuam tshuam rau cov ntev-ntau yam wireless yees duab transmitter thiab receiver. Thaum tam sim no ua hauj lwm frequency yog jammed los yog cuam tshuam nrog, Tus transmitter thiab receiver disconnect thiab hop rau tom ntej no muaj frequency rau reconnect.

Q2: Vim li cas koj thiaj xav tau cov FHSS muaj nuj nqi?

A2:
1. Vim hais tias lub teeb liab hops rau ib tug txawv frequency qhab, FHSS teeb liab yog resistant nqaim-qhab cuam tshuam.

2. Yog hais tias tus qauv frequency-hopping qauv yog tsis paub, teeb liab yog ib qho nyuaj rau kev cuam tshuam.

3. Jamming no kuj nyuaj yog tus qauv yog tsis paub; Yog hais tias qhov kis tau tus kab mob no tsis paub, Lub teeb liab yuav tsuas jammed rau ib zaug xwb hopping lub sij hawm.

4. Muaj kev sib nrig sib cuam tshuam, FHSS transmissions yuav muab ib tug qhab qhab uas muaj ntau hom conventional transmissions. FHSS teeb liab cuam tshuam rau nqaim-qhab naiskhu thiab vice versa.

Q3: Yuav teem cov FHSS ntawm koj wireless yees duab transmitter thiab receiver?

Q6: Does your FPV VTX support the FHSS frequency automatic jumping function to avoid interference?

FPV VTX is a one-way transmission and cannot support the FHSS frequency automatic hopping function.

FPV VTX is a one-way transmission, which can transmit the video from the aircraft to the ground receiver through the transmitter.

FHSS function, when the user finds that the signal sensitivity is declining or encounters an obstacle, it will notify the transmitter and receiver to modify the frequency at the same time and find a frequency with the least interference for transmission. If only the receiver modifies the frequency without controlling the transmitter to modify the same frequency, the frequency of the transmitter and receiver will be inconsistent and the transmission will be interrupted.

Because of the above requirement of notifying the transmitter to modify the frequency, the FHSS function needs to be based on a two-way transmission system.

Or your FPV VTX can support modifying the frequency function through the serial port. When you need to modify the frequency, the operator sends a preset serial port command from the receiver to the serial port of the transmitter. After receiving this command notification, the transmitter automatically changes to the next frequency point.

This is equivalent to your wireless transmission equipment, which has both a one-way video transmission function and a two-way data transmission function, which is equivalent to your current wireless control system. So whether it supports the serial port to modify the frequency of the transmitter depends on whether your current device supports it.

Our models below support such functionality.
