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.

AP Bridge

• Commit Changes and proceed to next ESTeem modem

• Reboot of approx 45 seconds


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

Mobile Client in Network

• Moves Between Multiple Access Points

Greatly Extended Range of Mobile Devices

• Vehicles• Forklifts

ESTeem Client Applications

EtherStation

• Single Ethernet device on wireless network• Only one device connected to ESTeem

Station Router

• Multiple Ethernet devices on client connection• Router between wireless network and connected devices• IP address for each device visible on network

Station Masquerade

• Multiple Ethernet devices on client connection• Firewall between connected clients and wireless network• IP address for each device hidden on network • All devices appear as a single IP on network

ESTeem Client Modes

Security Features

• Enter Network SSID• Select Encryption Type• Enter MAC address of connected

device


Security Features

• Encryption key or Passphrase for matching network Access Points


Security Features


• MAC Filter


EtherStation

• Commit Changes – ESTeem will no longer have an IP address



Custom Roaming Code

• Most Mobile Clients Will Move Only on Connection Loss• Overlapping Coverage Not Helpful

ESTeem Custom Roaming Code

• Signal Strength Threshold• Number of Missed Packets• Client Will Stay With Access Point Until Better Link Found• Client Will Obtain Highest Data Rate Possible

Authentication

• Verification Of Network ID and Security Code• Association with New Access Point• Disassociation of Old Access Point

ESTeem Client Roaming

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

LOS

Repeater Peer Links

• WLAN Address of Remote ESTeem• Path Cost or Path Length• Encryption Type• Data Rate

Routing Base Upon Spanning Tree Protocol (STP)

• Root Bridge• Path Length• Rapid Spanning Tree Protocol

Enable Each Fixed Route

• Mobile Clients Not Required in List
