The software defined radio (SDR) technology has undergone various technical and use-related changes in the past few years. SDR is a radio communication system where communication is carried out with software on an embedded system or personal computer. It eliminated the use of any hardware like amplifiers, filters, detectors, mixers, and modulators. Software defined radio can transmit and receive a broad frequency spectrum.

What is the software defined radio technology?

Software-defined radio conti

The broad spectrum of high-quality radio frequency components is founded on the varying requirements of in-building or distributed antenna networks and applications for railway, test, and measurement. The parts are compatible with each other and have very high-quality stable characteristics. This high-quality standard is the culmination of many years of radio frequency device development and production experience.

Radio frequency (RF) refers to the oscillation rate of electromagnetic radio waves

The growing incidence of property crimes and home invasions has fuelled the need for Radio Frequency Identification lock solutions for residential and other premises. Radio frequency identification (RFID) Locks is a non-contact technology that is widely used in industries for personnel tracking, access control, tollgate systems, and so forth.

Various enterprises are using Radio Frequency Identification locks of doors. The key cards used contain data encoded on RFID chip that is machine-readable.
