With the continuous development of WiFi technology, WiFi modules have applied to our daily household appliances. Among popular types of WiFi modules are applied in the Internet of Things, WiFi4 and WiFi5 are more widely used with high reliability and stability. This content briefly explains how to choose the right WiFi module.

 

Wi-Fi module is a crucial part for deploying a wireless security system. Generally speaking you need to consider its both software and hardware aspects when choosing a Wi-Fi module for your equipment.

There are various types of WI-FI modules available in the market today and each WI-FI Module features with their own specifications. To it’s eay to  select the WI-FI module , MinewSemi are here to have some tips for you should consider when choosing a WI-FI module for your products.


Supported Protocols

The merits of any wireless network depend on the protocol used. Each security system network has its own set of protocols, comes with different specification requirements. The protocol or standard of the WIFI module must be synchronized with the protocol or standard of the security system network in order to work successfully. The protocol or standard of the WIFI module must be synchronized with the protocol or standard of the security system network in order to work successfully. When you are considering for your applications, you may consider the important aspects are data rates and power consumption, etc.

 

The latest modulation technologies and their encoding rates are more efficient and can sustain higher data rates, but still support earlier technologies and rates for backward compatibility.


Transmission Range

Generally speaking, the network of WiFi are limited. The range largely depends on the network deployment of IP camera, router and wireless access points deployed on the network. It is very important for any security system that the WIFI module has the proper range to work properly.

 

Wi-Fi modules with 2.4GHz frequency range are slightly better than Wi-Fi with 5GHz frequency range, which is used by 802.11a, 802.11n and 802.11ac.

 

Operating Power Supply

The performance of a WIFI module depends on its operating power supply or voltage , just like any other electrical device. Wi-Fi modules must have higher transmission power output when the data rates are transmitted over long distance. Therefore, it’s necessary to find out the working voltage of wifi modules based on the area covered by the area covered by the security system.


Data Rate

Theoretically, the maximum data rate of Wi-Fi modules can range from 1 Mbps (802.11 b) to 6.75 Gb/s (802.11 ac). But contrary to popular belief, higher data rates are not always better, and you need to choose the possible solutions based on your requirements. For example, 802.11n and 802.11ac can be defined as higher data throughput applications. Therefore, the data rate requirements of the wifi model depend to a large extent on the specifications of the cameras installed on the security system.


Microprocessor

The microprocessor can be defined as a brain of device. For wifi modules, they provide the best hardware platform according to which a network of wireless security systems is designed combining high performance processing and communication. When deciding on the microprocessor, the criteria of choice is the cost, secondly program size and data memory, power consumption, processing power, etc.

 

Operating System or Driver Support

Different types of wifi module need to its own operation system and supported drivers, so that the users enable to configure their PC systems, smartphones or tablets to wireless security and networking systems. These support software must be taken into account when selecting a wifi module for a security system, as they are sometimes the only barrier to users accessing a wireless security system


Shape and Size

We also need to consider its size when we choose the right wifi module. The dimension of wifi module must be based on the size of security system. For large and distributed security systems, the wifi module should be support appropriately embedded into them.
