Top WiFi Antennas Manufacturers and Suppliers in USA

Wi-Fi plays a key role in the cellular Internet of Things (IoT) applications. Wi-Fi enabled IoT applications are secure and reliable, thus making Wi-Fi a highly sought communication protocol in designing IoT applications. However, uniform signal strength and diminishing signal strength with distance impose a major constraint in WLAN networks. To overcome this, we can use Wi-Fi antennas to increase the coverage by increasing the signal strength. In this article, we will identify some of the leading manufacturers and suppliers of WiFi antennas. 

What is WiFi? 

Wi-Fi is the underlying technology in realizing Wide Local Area Networks (WLANs). In simple words, it is a wireless technology used to connect different applications such as computers, tablets, smartphones, and other different devices which require internet access. IoT applications are the newest addition to this collection, where many modern IoT applications rely on Wi-Fi connection to establish a connection to the Internet.

Wi-Fi is the widely given name to the standard IEEE 802.11 which stands for facilitating wireless communication interfaces. In short, Wi-Fi stands for Wireless Fidelity. Also, Wi-Fi networks would have a range of about 300 m and operate in 2.4 GHz and 5.8 GHz bands. However, unlike other IoT communication protocols, Wi-Fi is equipped with more security and high reliability when compared to other IoT communication protocols. These features come with a cost, as the deployment and device cost of Wi-Fi is relatively high when compared to other communication protocols.  

What are WiFi Antennas? 

As mentioned above, Wi-Fi plays a key role in realizing WLAN networks. Due to the spread of WLAN networks, we should make sure that all the end-devices receive radio signals of enough strength and can transmit data with enough signal strength. To facilitate this need we use antennas, which are critical for dispersed networks over a large geographical area. However, requirements for Wi-Fi antennas solely depend on the nature of the application and the operating environment. The main objective of Wi-Fi antennas is to provide enough signal strength in the network and enhance the coverage of the WLAN network. These are usually mounted on top of the routers and gateways rather than on top of the end-devices. This is due to their considerable power consumption when compared to other IoT communication protocols.

There are two types of Wi-Fi antennas namely, omnidirectional, and directional. This is a broad division of Wi-Fi antennas, and these can be further divided into different sub-divisions. Now let us investigate some WiFi antenna suppliers and manufacturers.
