The little things often decide about satisfaction or dissatisfaction of end customer. Even good and cheap service may be perceived negatively if it has from time to time somefault. As an example we can name fluctuating in response to online gaming, jamming pictures when streaming sports tournament or stuttering an important call on Skype. What that for 99% of the time service works fine when at a critical moment it fails? The customer will be mildly annoyed ...

There are ways to achieve a more positive perception of the quality of services in relation to microwave links, which are probably mostly used for the last miles, and are often the weakest point in the transmission chain. Usually, however, they are treated only as a transmission medium and just data transfer from point A to point B is expected from them. In front and behind of the link the switches, routers and other termination equipment are connected which then define the parameters for each service.

However, this is often unnecessary, because the vast majority of modern microwave links are now equipped with at least a basic set of L2 features. Technicians know that the number of devices connected in a chain is often unnecessarily increased and the whole connection can look non-uniform and non-compact, it complicates the device aas well as service management. Additionally, certain features of quality control can work only if they are integrated directly into the device and can not be substitute by an external device. And the financials understand that the TCO is rising. So why not use the functionality integrated directly into the microwave technologies without compromising? Why not to reduce the investment required to deliver new services ...?

An example of such a solution is shown in the diagram. Diagram represents a simplified network topology of service providers (center) with the central access point (left) and the end customer (right).

In the diagram the backbone is represented by an Ethernet ring, which one segment is realized by the microwave link in the unlicensed band and the second segment by licensed microwave link. In one node of the ring a demarcation device (EDD) is connected what represents the POP for data, voice and video services. The central POP can be optionally equipped with a device for traffic analysis, visualization and management up to the level of the user service. The access part of the network is represented by one unlicensed E-band radio backuped by WiFi link and terminated by the customer‘s demarcation device. The real topology is much more complex of course, different paths lead through many of the transport and network devices, but the end customer is not interested in topology or used networking technology, the only relevant for him is the quality and transparency of provided service. Qualitative parameters are comprehensively covered by the SLA and the customer perception of it we are calling QoE - Quality of Experience.
