Carrier grade design refers to a system, hardware or software component that is extremely reliable, well tested and proven in its capabilities. Carrier grade systems are tested and engineered to meet or exceed “five nines” high availability standards, and provide very fast fault recovery through redundancy (normally less than 50 milliseconds).
The initial Carrier Grade requirements were focused on public wired and later wireless telecom infrastructures. Later the same Carrier Grade requirements were adopted to the critical infrastructures such as VoIP and the Internet at large.
The classic telecom Carrier Grade specifications focus on:
- Network Availability (so called 5 9s or 6 9s)
- Performance (best Key Performance Indicators for type of product)
- Security (product and network)
- Maintenance (operation and evolution).
For any product to meet Carrier Grade requirements there are many relative standards and product specifications they have to meet depending on the network and deployment. However, there are 12 key areas that any Carrier Grade product must address. The developers and operators should also understand the Carrier Grade LoRaWAN Gateway design implementation, specifications and their importance.
