Methods of Selecting 2.4 GHz transmitter and receiver modules

By sdga:NiceRF Wireless Technology Co., Ltd

What is 2.4 GHz transmitter and receiver module

2.4G refers to wireless technology that operates in the frequency band of 2400-2483MHz. A highly integrated chipset that utilizes this technology is referred to as a 2.4 GHz transmitter and receiver module.

 

Application of 2.4 GHz transmitter and receiver modules

These modules have a wide range of applications, including vehicle monitoring, remote control, telemetry, small wireless networks, wireless meter reading, access control systems, cell paging, industrial data acquisition systems, wireless tags, identification, non-contact RF smart cards, small wireless data terminals, security fire protection systems, Wireless remote control system, biological signal acquisition, hydrometeorological monitoring, and robot control, etc.

 

Methods of Selecting 2.4 GHz transmitter and receiver modules

1. Certification

The certified 2.4 GHz transmitter and receiver module means that the safety performance and quality requirements meet the requirements of certification rules and technical standards, and comply with international trade rules, which is conducive to improving product competitiveness. Certifications such as FCC ID certification in the United States, CE-RED certification, and ROHS certification in the European Union are commonly used.

 

2. Chip

The chip determines the computing capability of the 2.4 GHz transmitter and receiver module. A powerful chip is essential for good performance of the 2.4 GHz transmitter and receiver module.

 

3. Transmission distance

The transmission distance is also an important consideration when selecting a 2.4 GHz transmitter and receiver module. The farther the distance, the better of the 2.4 GHz transmitter and receiver module is used. The distance in the actual application of the 2.4GHz solution is used to determine which 2.4G wireless module is more capable of meeting the data transmission requirements.

 

4. Transmission rate

Transmission rate is usually the key factor for engineers due to it is related to the type of information transmitted. Therefore, when selecting the 2.4 GHz transmitter and receiver module, the application must be clear, and the data transmission rate in the working state must be the selection standard.

 

5. Antenna

The antenna is another important factor to be considered when choosing a 2.4 GHz transmitter and receiver module. When selecting the antenna, factors such as frequency, gain, input, and output impedance should be taken into account. The gain is the most important parameter, as a higher gain leads to stronger signals and longer transmission distances. Our 2.4 GHz transmitter and receiver modules can be matched with PCB wire antennas, 2.4G spring antennas (built-in), 2.4G rod antennas, and 2.4G sucker antennas (external).
