Overview
Wi-Fi HaLow is a newly established wireless communication technology based on IEEE 802.11ah by the Wi-Fi Alliance. It’s a next-generation wireless LAN technology that can transmit data from various IoT devices over long distances.
sHaLow/all, which incorporates Wi-Fi HaLow, serves as a wireless gateway converter providing Wi-Fi HaLow wireless communication capabilities to equipment supporting RS232/RS422/RS485 signals. It supports RS232/RS422/RS485 with a maximum communication speed of 921.6kbps in wired sections and incorporates Wi-Fi HaLow with a maximum of 2Mbps in wireless sections, overcoming the limitations of short-range communication technologies such as existing Wi-Fi and BLE.
Users can use Wi-Fi HaLow to construct long-distance wireless networks based on serial communications, enabling the formation and use of various M2M networks such as smart grids and sensor networks.
Long-range, low-power WLAN technology Wi-Fi HaLow
Approved by the Wi-Fi Alliance in 2016, IEEE 802.11ah (Wi-Fi HaLow) is a WLAN technology that utilizes the Sub 1GHz band. The reality is that the 2.4GHz ISM band, where existing Wi-Fi and BLE etc. are applied, has increased congestion due to various communication devices and decreasing stability.
Wi-Fi HaLow overcomes these issues by utilizing Sub 1GHz, surpassing the limit of approximately 100m communication distance that traditional wireless communication technologies possess and implementing medium to long-range communications of about 1~1.5km. Thanks to its low power characteristics, it shows excellent advantages in sensor networks and M2M communication networks powered by batteries or similar sources, making it a next-generation IoT-specific WLAN technology.
Building a Wireless Serial Network
Through a Wi-Fi HaLow network, you can easily communicate with, control, and monitor remote serial devices. Various communication modes such as 1:1 communication mode TCP Server/Client, UDP and others allow you to configure and utilize the network according to your user environment.
Enhanced Reliability and High Performance
sHaLow/all supports excellent security protocols for information security. For sites where enhanced security is needed, it provides WPA2-PSK, allowing users to use more reliable wireless communication. Moreover, considering the characteristics of various usage sites, it uses components that offer excellent reliability and high performance at the same time. It is a multi-functional high-performance device.
