RF Transmitter and Receiver: Key Components in Wireless Communication

RF (Radio Frequency) transmitters and receivers are fundamental components in modern wireless communication systems. These components play a pivotal role in enabling various wireless technologies, from mobile phones to Wi-Fi routers, to operate seamlessly. In this article, we will explore the significance of RF transmitter and receiver in wireless communication and delve into their essential functions and applications.

RF Transmitter: Sending Signals Wirelessly

An RF transmitter is a crucial element in any wireless communication system. It is responsible for converting electrical signals into radio waves that can travel through the air and be received by compatible devices. RF transmitters are found in a wide range of applications, including radio broadcasting, remote control systems, and data transmission.

One of the key features of an RF transmitter is its ability to modulate the carrier signal with the information to be transmitted. This modulation process allows the transmitter to encode data, voice, or other forms of information onto the radio waves. The modulated signal is then amplified and broadcasted through an antenna.

In modern wireless technologies, such as Bluetooth and Wi-Fi, RF transmitters are the driving force behind the wireless connectivity that allows devices to communicate with each other over short or long distances.

RF Receiver: Capturing and Decoding Signals

On the receiving end, the RF receiver is responsible for capturing the transmitted radio waves, demodulating them, and converting them back into electrical signals that can be processed by electronic devices. RF receivers are integral components in devices like car radios, GPS systems, and satellite television receivers.

The receiver's demodulation process is crucial because it extracts the original information from the modulated carrier signal. This process allows the receiver to recover the transmitted data, audio, or video signal accurately. In essence, the RF receiver acts as the gateway for converting radio waves into usable information.

Applications of RF Transmitters and Receivers:

Wireless Communication: RF transmitters and receiver is the backbone of wireless communication system, enabling devices to transmit voice, data, and multimedia content over the airwaves. They are vital for mobile phones, two-way radios, and wireless Internet connections.

Remote Control Systems: Many remote control devices, including TV remotes, garage door openers, and toy controllers, rely on RF transmitters and receivers to send and receive signals.

Telemetry and Data Acquisition: In industries like agriculture and environmental monitoring, RF technology is used to collect data wirelessly from remote sensors and devices.

Security Systems: Wireless security systems, such as home alarms and surveillance cameras, use RF transmitter and receiver for communication between sensors and control panels.

Conclusion:

RF transmitters and receivers are the unsung heroes of the wireless world, making it possible for us to communicate, control devices remotely, and access information seamlessly. As technology continues to advance, these essential components will continue to evolve and play a pivotal role in our increasingly connected world.

Industry trend｜Another domestic manufacturer launches new WiFi6 chip for low-power IPC

AltoBeam recently launched the new generation of Wi-Fi 6 low-power chip ATBM6461, which was independently developed and has complete intellectual property rights. The main selling point of this chip is WiFi6; the other is low power consumption. From these two functional points, it is almost tailor-made for low-power IPC.

WiFi IPC is the most important product line of consumer IPC, accounting for 80% of the market share, and 80% of them use WiFi4 transmission. As users have higher and higher requirements for image quality, interactive experience, and application scenarios, the market needs higher speed, lower power consumption, and more stable transmission technology. The development of WiFi6 technology can meet the needs of industry development. From WiFi, WiFi5 iteration to WiFi6, from single-band to dual-band, they are all in line with the trend of technology and standard iteration.

In the "2024 Visual IoT Consumer Market Analysis Report", we introduced that WiFi6 IPC has the following advantages over WiFi4 IPC:

1. High speed: WiFi6 is about 50% higher than WiFi4 of the same specification, ensuring a smooth video experience at the same distance.

2. Low power consumption: WiFi6 allows devices to plan communications with routers, reducing the time required to keep the antenna powered on to transmit and search for signals, which means reducing battery consumption and improving battery life performance. The actual power consumption is 20%~30% lower than WiFi4.

3. Stability: WiFi6 introduces cellular OFDMA technology to achieve high-density access routing, and parallel transmission is highly real-time. WiFi4 devices access routing by time-division multiplexing to grab network speed, so WiFi6 can solve the probabilistic disconnection and jamming problems of WiFi4.

4. Iteration trend of new and old standards: WiFi4 to WiFi6 is the iteration of new and old standards, similar to cellular 2G to 4G; as prices approach or remain the same, the iteration will be accelerated. At this stage, WiFi6 has the added advantage of differentiated competition with new selling points in addition to performance advantages compared to WiFi4.

On WiFi6, AltoBeam's data said: ATBM6461 supports all modes from MCS0 to MCS11 specified in the Wi-Fi6 protocol, and the physical layer supports modulation and demodulation up to 1024QAM, with a maximum bit rate of 287Mbps. At the same time, the ATBM6461 chip has further significantly improved the RF performance indicators to ensure that more data can be transmitted at a longer distance. ATBM6461 fully supports various advanced technologies in the Wi-Fi 6 protocol, such as LDPC encoding and decoding, Beamforming, Extended Range frame structure (ER-SU) and dual carrier modulation (DCM). Therefore, ATBM6461 can greatly improve the sensitivity index and the transceiver performance in complex network environments, and the signal coverage range can also be greatly increased.

In terms of low power consumption, for battery-powered terminal product applications, ATBM6461 pays special attention to optimizing the power consumption of the chip, and further extends the battery life by supporting the TWT function in the Wi-Fi6 protocol.

It is said that AltoBeam's new low-power WiFi6 product will soon be launched in the North American market. Recently, the main players in the domestic WiFi6 chip market include: Aikewei, Broadcom Integrated, Espressif Technology, Aojie Technology, etc. The "2025 Visual IOT Low Power Market Analysis Report" has started, and industry professionals are welcome to actively participate in our report. We will also include good products and good ideas in the report.

RDS Data Extraction with RFtap and Wireshark

RDS (Radio Data System) is a communication protocol standard used for embedding small amounts of digital information in traditional FM radio broadcasts. It enables radio stations to transmit data such as station identification, program information, and traffic updates. 

To capture and decode RDS data, one method involves using a Software Defined Radio (SDR) along with GNU Radio and RFtap. GNU Radio provides a framework for creating software radios, while RFtap acts as a bridge between GNU Radio and conventional network monitoring and packet analysis tools like Wireshark.

Unfortunately, as of the time of writing, RFtap is no longer being maintained and does not work with the latest version of GNU Radio (version 3.10.10). This post offers guidelines for rebuild and using RFtap with the new GNU Radio release.

This post assumes that the reader has access to DVB-T dongles based on the Realtek RTL2832U and a PC running Ubuntu or Debian Linux. For this, I used an RTL dongle with Rafael Micro R820T tuner and Ubuntu 24.04 LTS release.

As the first step install the following GNU Radio build dependencies into the OS:

sudo apt-get install cmake libboost-all-dev \ liblog4cpp5-dev qtcreator qtbase5-dev \ qt5-qmake python3-cheetah python3-numpy \ python3-pygtk python3-gi python3-gi-cairo \ gir1.2-gtk-4.0

sudo apt install git g++ libgmp-dev swig \ python3-mako python3-sphinx python3-lxml \ doxygen libfftw3-dev libsdl1.2-dev \ libgsl-dev libqwt-qt5-dev libqt5opengl5-dev \ python3-pyqt5 liblog4cpp5-dev libzmq3-dev \ python3-yaml python3-click \ python3-click-plugins python3-zmq python3-scipy \ libcodec2-dev libgsm1-dev libusb-1.0-0 \ libusb-1.0-0-dev libudev-dev \ python3-setuptools

sudo apt install pybind11-dev python3-matplotlib \ libsndfile1-dev libsoapysdr-dev soapysdr-tools \ python3-pygccxml python3-pyqtgraph

sudo apt install libiio-dev libad9361-dev \ libspdlog-dev python3-packaging python3-jsonschema \ python3-qtpy

sudo apt remove swig

Next, clone and build Volk (Vector-Optimized Library of Kernels)

mkdir ~/rf cd rf git clone --recursive https://github.com/gnuradio/volk.git cd volk mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../ make sudo make install sudo ldconfig

After installing the Volk library, we can proceed to build GNU Radio.

cd ~/rf wget https://github.com/gnuradio/gnuradio/archive/refs/tags/v3.10.10.0.tar.gz tar -xvf ./v3.10.10.0.tar.gz cd gnuradio-3.10.10.0 mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../ make -j8 make test sudo make install sudo ldconfig

Now GNU Radio is installed with all necessary components. To enable RTL SDR support, we must build and install Osmocom RTL SDR libraries and SDR components.

cd ~/rf git clone https://gitea.osmocom.org/sdr/rtl-sdr.git cd rtl-sdr mkdir build cd build cmake ../ -DINSTALL_UDEV_RULES=ON make sudo make install sudo ldconfig

cd ~/rf git clone https://gitea.osmocom.org/sdr/gr-osmosdr cd gr-osmosdr mkdir build cd build cmake ../ make sudo make install sudo ldconfig

Before plugging in the RTL-SDR dongle, we need to prevent the kernel modules for the RTL-SDR USB device from being loaded into the kernel and taking ownership of the device. To do this, simply navigate to the /etc/modprobe.d directory and create a file called rtl-sdr-blacklist.conf with the following content:

# This system has librtlsdr0 installed in order to # use digital video broadcast receivers as generic # software defined radios. blacklist dvb_usb_rtl28xxu blacklist e4000 blacklist rtl2832 blacklist rtl2830 blacklist rtl2838

Next, you should clone and build the FM RDS/TMC transceiver module for GNU Radio.

cd ~/rf wget https://github.com/bastibl/gr-rds/archive/refs/tags/v3.10.tar.gz tar -xvf ./gr-rds\ -v3.10.tar.gz cd gr-rds-3.10 mkdir build cd build cmake .. make sudo make install sudo ldconfig

For the next steps, we need to have Wireshark and RFTap. Wireshark can be installed using a package manager.

sudo apt-get install wireshark

To run Wireshark without requiring root user permissions, use the following set of commands:

sudo dpkg-reconfigure wireshark-common sudo usermod -a -G wireshark $USER newgrp wireshark

A message may be prompted in the first step above and proceed by selecting the "Yes" option.

Now restart the OS and continue with the RFTap installation.

The official RFTap repository is no longer being maintained and is not compatible with newer versions of GNU Radio. For this step, please use the RFTap fork available in my GitHub repository. This version has been successfully tested with GNU Radio 3.10.10 and Wireshark 4.2.2.

cd ~/rf git clone https://github.com/dilshan/gr-rftap.git cd gr-rftap mkdir build cd build cmake .. make sudo make install sudo ldconfig

Now get the modifier version of rds_rx_rftap.grc from the above repository.

The Wireshark Dissector file for RDS data is also available in the repository. Copy it to the ~/.config/wireshark/plugins directory. Create the directories if they do not exist.

Launch Wireshark and monitor the loopback (lo) adapter. Start GNU Radio and execute the rds_rx.grc file, which was downloaded in the above step.

If all the steps are performed correctly, the RDS data should appear in the packet list pane as UDP messages. The dissected messages can be observed through the packet bytes pane.
