Application field

30.214 defines the performance of the Broadband Access System (BAS), also known as a distributed access architecture (DAA). It specifies the performance requirements and test procedures for the system type, equipment type, and component to ensure the performance of the BAS.

30.214 defines a common set of measurements to evaluate the performance of the physical layer, thereby overcoming the difficulty that the performance of BAS is difficult to measure and evaluate. The performance of BAS can be quantified according to the evaluation metrics and requirements defined by 30.214, so that users, vendors, and other stakeholders can evaluate and make informed decisions on the selection of BAS.

30.214 provides a foundation for the commercial deployment of BAS, ensuring that the performance of the system meets certain standards. With the definition of 30.214, products that have passed its requirements can be trusted by buyers who require enhanced performance.

Working principle

Because the working principle of 30.214 is related to the BAS, it is necessary to analyze the working principle of BAS first. BAS is a type of broadband access network architecture. It divides the distributed base stations into two types: centralized base stations (CCB) and distributed base stations (DBS).

A DBS is attached to the central unit that controls the network. All components of the network (i.e., DBSs, CCBs, and nodes) share the available spectrum in a network. The key principle of 30.214 is to ensure that each component of the network works together to support the overall performance of the system.

30.214 sets performance requirements for each part of the system, such as the transmission rate, latency, frame error rate, and power efficiency. These requirements ensure that the system is able to provide reliable services for the users. It also sets out the applicable test methods to accurately measure the performance of the components.

30.214 also specifies the performance requirements for the overall system, such as the length of the transmission route, the power usage, the distance between nodes, and the maximum number of simultaneous connections. These requirements ensure that the system is optimized to meet the performance target of end users.

In conclusion, 30.214 defines the performance and test criteria for the Broadband Access System(BAS), and sets out the requirements for both the components of BAS and the overall system performance.
