Cost-effective network topology to minimize installation costs |
| |
Creating wayside networks is a labor and resource-intensive project, particularly since a typical rail system covers many miles. An efficient network topology is needed to prevent an already-challenging project from becoming insurmountable. |
| |
|
|
High network availability to ensure stability |
| |
Wayside networks include critical passenger information and security systems and are not allowed any failures. Network redundancy must be implemented in wayside applications to ensure uninterrupted network operations. |
| |
|
|
Network management software for simpler network supervision and troubleshooting |
| |
Administrators need network management software to help diagnose and preemptively maintain the health of the network, reducing time expended on troubleshooting trackside communications. |
| |
|
|
Long-haul transmissions to accommodate lengthy wayside applications |
| |
Railway systems can span for miles, and any trackside networks will have to cover a corresponding distance. This makes long-haul transmission capability a major concern for these networks. |
| |
|
|
Compact size for use in space-constrained wayside cabinets |
| |
Ideal networking devices would possess a compact form factor to conserve the limited space in wayside control cabinets. |
| |
|
|
Able to withstand extreme temperature variations |
| |
Since the temperature conditions found in outdoor trackside environments can be extremely varied, networking devices employed in wayside cabinets must be capable of operating reliably in a wide temperature range. |
| |
|
|
Rugged industrial design for reliable communications in harsh environments |
| |
| |
Ethernet switches must meet the high reliability requirements demanded by industrial applications. EN50121-4 certifications can help establish the fitness of a device for wayside applications. Elements of a reliable, rugged design include:
- -40 to 75°C operating temperature
- High MTBF values
- IP30-rated housing protection
- Dual power inputs
- Fanless design
