2.4G and 433M practical applications, who is better?

December 03, 2020

The frequency range of 433.05~434.79MHz and 2.4~2.5GHz is a domestic license-free ISM (Industrial, Scientific and Medical) open frequency band. The use of these frequency bands does not require authorization from the local radio management, so the two frequency bands have been obtained. widely used.

Many users have many questions about the mainstream products in these two frequency bands. We have simply summarized and explained the problems that customers are concerned about, as shown in the table below.

Application selection

Based on the relatively high diffraction sensitivity of 433MHz, the 433MHz product can be actually used in the communication system of the master-slave mode in the following figure. In this way, the master-slave topology has the advantages of simple network structure, easy layout, and short power-on time. This is actually the prototype of the early smart home. 433MHz and 470MHz are now widely used in the smart meter reading industry.

The 2.4GHz application point is a networking protocol developed based on its high-speed transmission rate. The following picture shows the network structure of the intelligent security monitoring system designed by a customer for a large hotel. It uses ZM5168 series ZigBee wireless module and is equipped with FastZigBee networking protocol. Because our designed network has adaptive function and is very powerful in power consumption. Great advantages, the project includes hotel wireless door locks, wireless smoke and other equipment. The hotel security monitoring room and front desk can monitor the security status of the hotel building in real time.

All in all, if the network topology and functions are simple, one master and multiple slaves, but the network environment is complex and cost-limited, it is recommended to filter the 433MHz product preferentially; if the network topology is complex, the functions are numerous, the network is robust, and the power consumption is low. The development of a simple, 2.4GHz network with networking features will be your best choice.

Gas Bbq Grill

Gas burner principle

The general use of stainless steel as the furnace material, through the electronic pulse ignition, the use of oil liquefied petroleum gas or natural gas combustion, heat to heat the above four independent high temperature crystal red gas heating plate and then baking food on the iron plate. With the energy-saving component control, the electronic pulse switch can also control the size of the flames to control the temperature of the iron plate, practical and convenient.
