Network Overview
Product Overview
The Building Automation system uses Millennial Net's i-Bean® technology to allow monitoring
and configuring of building thermostats over a wireless network. When installed, the i-Bean
wireless network replaces the RS-485 bus typically used between the controller and the
associated thermostats, eliminating the need for running cables between devices. Millennial
Net's Gateway Server provides the interface between the controller and the Millennial Net
Sub-base Routers attached to each thermostat. Figure 1-1 provides a view of the various
components of the Building Automation system.
Figure 1-1. Millennial Net’s Building Automation Wireless Network
Client Monitor System
The client monitor system contains the third party Building Management System for
monitoring and control of the thermostats on the wireless network.
Controller
The controller is a data collection and storage device that is designed to communicate
directly with TCS/Basys Controls S-series microprocessor-based thermostats over an RS-485
cable. Millennial Net supports the following third party controller models:
• Basys Controller, model: QD2020ie
Building Automation User’s Guide 1-3
General Network Characteristics
• WebGen Controller, model: Web-i
• Tridium Controller, model: JACE-403
Gateway Server
Millennial Net’s Gateway Server translates messages from the controller’s RS-485 port to
Millennial Net packets for wireless transmission to a thermostat’s Sub-base Router and vice
versa. The Gateway Server also manages the wireless network.
Sub-base Router (mounted to back of thermostats)
Millennial Net’s Sub-base Router provides each thermostat with wireless communications.
The Sub-base Router converts data on the thermostat’s RS-485 line to/from Millennial Net
packets.
Standalone Router
Millennial Net’s Standalone Router is used in applications requiring increased distances
between Sub-base Routers, Sub-base Router(s) and the Gateway Server, or to circumvent
obstacles preventing good wireless communications.
General Network Characteristics
Characteristics of the Building Automation system include the following:
• Communication path: Messages are passed from i-Bean node to i-Bean node until they
reach their destination, extending the range and allowing for routing around obstacles.
Up to six intermediate i-Bean nodes (Sub-base Routers or Standalone Routers) can hop the
signal from source to destination.
•Range: Typically, 20 meters maximum between any of the i-Bean nodes. This value is
based on a same-floor application, in which all the devices are on one floor without any
obstacles between them. The actual distances between devices will vary depending on
environmental issues, such as the number of floors between devices, construction
material, etc.
•Number of thermostats: Up to seven thermostats and seven Sub-base Routers and/or
Standalone Routers can be used in a wireless network with one controller and one
Gateway Server.
•Polling rate: Typically, from two to three nodes (Sub-base Routers with attached
thermostats or Standalone Routers) per second, depending on network topology. A star
network topology, in which Sub-base Routers or Standalone Routers are only one or two
hops from the Gateway Server, supports a higher polling rate than a linear topology, in
which the furthest node is reached through several hops. For more information on
different network topologies, refer to ’i-Bean Network Overview’ on page 1-4.
•Radio frequency: i-Bean network nodes use the license-free 916 MHz band.
•FCC Compliance: All radio components are designed to be compliant with FCC 15.249.

Network Overview
i-Bean Network Overview
Millennial Net's innovative, self-organizing i-Bean network technology combines micro-power
sensor interface Sub-base Routers and Standalone Routers with a Gateway Server to form a
reliable, scalable Star Mesh wireless network (see Figure 1-2). This is a unique solution for low
data-rate networks that provides fault-tolerant networking. Our patent-pending network
protocol creates robust, fully redundant wireless links from the Gateway Server to the Sub-base
Routers and optional Standalone Routers through a self-configuring mesh network.
Figure 1-2. i-Bean Network Topology
Each i-Bean network device is configured at the factory with a unique device ID and a group ID.
The device ID indentifies the device within a network, while the group ID identifies the i-Bean
network that the device is associated with. Both IDs are statically assigned and cannot be
changed by a system user. The group ID allows i-Bean devices to establish networks within the
same location without interfering with each other. Sub-base Routers and Standalone Routers
can join the network only if they have the same group ID that is assigned to the Gateway
Server.
The i-Bean network devices self-organize at power-up and re-configure in response to changes
in the environment, network traffic, device status, and location. These devices enable mobility
and minimize installation and operating costs.
Figure 1-3 illustrates several different possible i-Bean wireless network topologies. Standalone
Routers are included randomly in the Star Mesh example to illustrate how they can be placed
where needed to increase the communication range between device hops or circumvent
obstacles.

i-Bean Network Hardware
Performance Considerations
Since the i-Bean wireless network uses radio waves to communicate between devices, there are
a number of items that need to be considered when implementing this type of network. This
section of the manual provides a number of suggestions that will ensure that your wireless
network will operate at its peak level of performance.
General Installation Recommendations
When installing the i-Bean wireless network devices, observe the following recommendations
when possible for optimal performance:
•Higher locations for i-Bean devices are generally better than lower locations. A
higher location usually provides a clear communication path over obstacles.
•Locate i-Bean devices at least one foot from metal shielding on all sides. Avoid
obstacles such as book shelves and file cabinets.
•Avoid sources of electrical noise, such as motors, pumps, and welding machines.
Locate i-Bean devices at least two feet from fluorescent fixtures.
•Avoid other devices using 900 MHz Industrial/Scientific/Medical (ISM) band. This
includes such items as cordless phones, intercoms, and walkie-talkies.
Warning
These electronic products are sensitive to electrostatic discharge (ESD).
Permanent damage to these devices can result if subjected to high energy
electrostatic discharges.
Proper precautions are recommended to avoid performance degradation or loss
of functionality.
Note: For instructions on installing the i-Bean devices, refer to the Quick Start Guide for
Building Automation (P/N DOC-0010).
