MODES OF OPERATION
The ESTeem Model 195Ea is a sophisticated wireless networking device that can be configured for multiple modes
of operation. Determining the correct mode of operation for the ESTeem is the first step in creating a reliable
wireless network. This chapter will explain each mode of operation, provide example applications and detailed
programming information for each mode. Please review the following modes of operations. If you do not see an
example of your application, please contact ESTeem support at 509-735-9092 for help in selecting your mode of
operation.
Ethernet Bridge Mode (AP Bridge)
The most commonly used mode of operation with the ESTeem Model 195Ea is the Ethernet bridge mode. The
Ethernet bridge mode will connect two or more ESTeem 195Ea’s while passing all network traffic that arrives in both
the wireless and connected Ethernet ports; including all global network traffic (Figure 1). This mode will work in
most wireless applications of the 195Ea to wirelessly connect two or more remote Ethernet devices or networks.
The Ethernet bridge mode is also used in repeating (Figure 2) and in self-healing Mesh networks (Figure 3) for fixed
(non mobile) applications.
Example Applications
Building to building remote wireless LAN networks
Point to point wireless Ethernet communication devices
Multi-point wireless Ethernet networks
Remote Supervisory Control and Data Acquisition (SCADA) networks
Redundant, self-healing Mesh networks
Fixed locations with mobile ESTeem 195Ea’s
Applications Where Ethernet Bridge Mode Not Used
Mobile applications (see Mobile Clients)
Connections to large Ethernet traffic networks such as large office buildings or plant networks (see Router
modes)
