Customizable RF frequency Generator and receiver
kowshik1729 last edited by
I would like to know how can we generate RF waves with customizable frequency. For example the generic RF modules which we get in the market operates at a frequency of 433MHz. But I wanna make a transmitter and receiver pair that can operate on freqeuncy that can be customized by me. How can I do it? Please guide me. Thanks in advance..!!

This is an interesting question, Traditionally we are using mixers, filters, amplifiers, modulators/demodulators, detectors, etc to build a radio communication system and it's tightly coupled with hardware. And there are many types of frequency modulation like FM, AM, FSK, LoRa etc.

To generate a different band we need to use a specific combination of mixers, filters, amplifiers, modulators/demodulator, also most of the scenario we only use a specific frequency to communicate in cost-efficient ways like 2.4 GHz for WiFi and Bluetooth but we use different modulations like GFSK in BT Classic and DSSS, FHSS in IEEE802.11 etc. And building many different combinations of mixers, filters, amplifiers are not cost-effective and economic.But using the SDR (Software Defines Radio ) we can achieve this,
A basic SDR system may consist of a personal computer equipped with a sound card, or other analogue-to-digital converter, preceded by some form of RF front end. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware (electronic circuits). Such a design produces a radio which can receive and transmit widely different radio protocols (sometimes referred to as waveforms) based solely on the software used.

So as an answer to your question, yes we can generate radio frequency but it's high cost and not economical, also with the help of the SDR system we can solve the issues.
You can also try SDR via online using https://eshail.batc.org.uk/nb/ , it was hosted at Goonhilly Earth Station in Cornwall, England.
Arduino also providing Portenta Carrier board that will add extra capabilities to your H7 board
The Portenta Carrier exposes all of the extra capabilities of the processor on your microcontroller board through connectors and peripherals that do not physically fit on it. There are connectors for USB, RJ-45, CAN bus, audio in and out lines, camera, DisplayPort, etc.
This design expands the default communication ports of Portenta boards to other wired and wireless protocols. Gigabit Ethernet will let you transform your board into a dedicated access point, a network drive, or even a serial-to-ethernet bridge. Adding a SIM card to the board makes it possible to connect to NBIoT or GPRS networks. Thanks to its LoRa connectivity you can design your own gateway to host your wireless sensor network.
Adding an 8-bit camera sensor to the Portenta Carrier camera connector will help you implement any kind of computer vision application. And if the onboard computing power is not enough, you could enhance your board’s AI capabilities by adding state-of-the-art Machine Learning modules through the Carrier’s miniPCI connector (like Google’s Coral unit of computation).
@kowshik1729 thanks bro
The theme of the challenges is Oil & Gas, Fuel Retailing, Marketing and Energy Conservation and they also provided complete problem statement on their website.
Should we only develop solutions only related to Oil & Gas or it's an open innovation?
