MANET MEWLink 900

MANET MEWLink 900

Introducing an RF module for the ISM Band (917 ~ 923.5MHz) that supports MANET.

MANET MEWLink 900 Features

MANET MEWLink 900 is an RF module for the ISM Band (917 ~ 923.5MHz) that supports MANET. With multi-hop based network formation and stable routing, it enables predictable communication operations in the field.

Build a predictable multi-hop MANET where transmission/response time can be estimated

MANET MEWLink repeatedly searches and establishes routes, and prevents signal transmission/reception loss throughout the entire communication process over an established path. As a result, transmission and response times become predictable, and a wireless network can be built where uncertainty is effectively removed—except for physical loss due to interference or environment.

Improve reliability by avoiding signal collisions during routing setup

MANET MEWLink applies an on-demand (reactive) approach that suppresses unnecessary traffic unrelated to actual communication. It can establish redundant routes without extra overhead, and fundamentally avoids real-time signal collisions during communication, improving reliability. This also enables a complete mesh network where all nodes can communicate with redundant paths.

Media Transmission & MANET Characteristics


In general MANET networks, the ability to avoid signal collisions during communication is not reflected in routing decisions, so minimum QoS to guarantee stable latency is not supported. However, MANET networks using MANET MEWLink can predict transmission/response time and avoid collisions, enabling media transmission such as voice in 1:1 communication.
