MNS-300EM is an embedded module that provides mesh connectivity for low-power portable devices to connect to a 802.11s capable mesh network. It features an 802.11ac radio, and a complete TCP/IP network protocol stack with an optimized QCA9377 wireless radio driver and security supplicant in a self-contained hardware package. It also supports enterprise security which ensures data integrity and privacy for highly sensitive applications.Embedded Wi-Fi Mesh with Enterprise Security

Silex Mesh Delivers High Throughput and Reliable Connectivity

The MNS-300EM features NXP’s power efficient and cost optimized applications processor, the i.MX 6ULL, featuring a single ARM Cortex-A7 core, with an 802.11ac radio, a complete TCP/IP network protocol stack, and an optimized QCA9377 wireless radio driver and security supplicant in a self-contained hardware package. It also supports enterprise security, including WPA2 with 802.1x authentication, which ensures data integrity and privacy for highly sensitive applications. It can be used as a mesh node to extend your existing BR-400AN based mesh network infrastructure.

Mesh networks are "self healing," since the network automatically finds the fastest and most reliable paths to send data, even if nodes are blocked or lose their signal. In addition to creating a strong, reliable Wi-Fi signal, it is also easier to setup and manage a mesh network when compared with traditional Wi-Fi.

1. Two Operation Modes:

MNS-300EM can operate in two modes. It can automatically toggle between the two modes depending on its wireless environment.

Mesh Point Mode (MP):
As a mesh point, MNS-300EM can provide mesh back-haul /network connectivity. It is compatible with our BR-400AN. Mesh points are aware of potential neighbors and can form new mesh links if the current mesh link is no longer available.

WLAN Station Mode (STA):
MNS-300EM in STA mode, can connect to a traditional access point as a wireless client and join the wireless network.

2. Automatic Profile Switching

MNS-300EM can save up to five mesh network profiles that it wants to automatically toggle between. As your device moves between different mesh networks, it automatically configures itself to the network profile with the best signal strength. 

3. Multiple Hop Support

The amount of hops represents the number of devices connected to relay data and provide multiple paths of communication in your mesh network. We recommend mesh networks to comprise of no more than 32 nodes (MNS-300EM’s & BR-400AN’s). Our optimized implementation allows multiple hops (5 recommended) without degradation in performance.

4. Add Wi-Fi to your Serial and Wired LAN Device

By embedding the MNS-300EM into your device, you can easily connect your serial (RS232C) or Ethernet device to your traditional Wi-Fi or Mesh network.

5. Configuration via Bluetooth

AMC Manager Mobile application allows users to configure your mesh device remotely using your tablet or cell phones via Bluetooth. This allows accessibility to the devices in remote and hard to reach areas.

AMC Manager

The MNS-300EM is compatible with the optional device management software "AMC Manager®". With this software, network administrators can execute the functions required for device management of Silex networking products from one point, for example monitor device status, configuration settings, update firmware, automatically record device operating logs and restart the devices.

Mesh Monitor

Mesh Monitor is AMC Manager® plug-in option to visualize mesh network composed of BR-400AN . This application aids the user with setup and operation management. User can map BR - 400AN and check communication path, connection link status between terminals, radio field strength at a glance.
