Modes of Operation

Most commonly used mode of operation

Bridges wireless and wired network ports

All data from both wired and wireless are shared

Simple network configuration • Single IP subnet• No IP routing required

Applications• Fixed Locations• Small or isolated Ethernet network

Access Point Bridge

Provides wireless access to mobile clients

• Developed for WiFi type access• Available to all ESTeem client modes

Connects mobile clients to fixed Ethernet network

Expands range between mobile clients

Access Point

Mobile Wireless Network With Overlap Coverage

Note:

Antenna’s shown are for illustration purposes. There are many antenna options available depending on your application.

195E acts as router between wireless network and wired network

More extensive network configuration required

• Wired and wireless must be on different subnets• Network router required

• Existing network router• Configuring ESTeem 195E as router

Applications

• Connecting wireless network to large plant network• Network segmentation

Access Point Router

195E used as firewall between wireless network and wired network

Wireless network requests on wired network will pass but wired network requests will not

Used for isolating wireless network from wired Ethernet network

Applications

• Network firewall requirements• Functions similar to home cable/DSL routers

ESTeem Mesh Technology

Redundant Repeater Routes

• Configured Priority Routing• Manual Input• Direct Control Over Routing

• Auto Configuration • Shortest Path to Root Bridge• Highest Signal Strength

Priority Routing Configuration

• Multiple Links Create “Meshing” Pattern• “Self Healing” from Spanning Tree Protocol

Redundant Path Overview
