Tropos

Broadband

Capacity for bandwidth-intensive applications, including video

Network traffic load driven by application needs, not network limits

Reliable

Can be designed with no single-point-of-failure

Resistant to interference

Secure

Multi-layer, defense-in-depth security to network’s edge

Multi-application

One network supports many applications (including IEC61850, serial SCADA)

Multiple virtual LANs, each with own address space, security policies, QoS policies

Ubiquitous coverage

Connectivity for all field equipment and mobile workers

Private broadband wireless field area network requirements

Broadband

600 Mbps data rate, 300 Mbps in 2.4 GHz band and another 300 Mbps in 5 GHz band

Reliable

Access to 653 MHz of spectrum plus automatic interference avoidance software mitigates interference

Mesh networking chooses optimal path through network, routes around interference, obstructions, failures, etc.

Secure

IPsec VPN, internal firewall, and more provides security at network edge for wireless and wired

ports

Multi-application

VLANs supported by IP address and SSID

Each VLAN has own address space, security policies, QoS policies

Ubiquitous coverage

Provides coverage for devices and workers throughout service territory

ABB Wireless networks meet field area network requirements

Tropos advantages

Resilient, high-availability architecture, controllerless

Based on 802.11x standards

High performance, mobility

Multi-layer security at network edge

One network for many applications

Application-based Quality of Service (QoS)

Application traffic segmentation

Scalable to economically cover small areas to

thousands of square miles

Standards-based, connects off-the-shelf endpoints and

clients

In congested environments network

performance can “fall of the cliff”!

In mining operations this can lead to

potential loss of productivity and capital

utilization

Wireless equipment and networks can

be designed extend capacity and

provide reliability even in congested

environments
