1. What is W+A doing in this project?
We are converting the radio line network between the mobile radio systems operated by Sunrise to the state of the art. We usually install the latest Huawei components.  

2. What is the approach to or course of action for tackling such an assignment?
After receiving the assignment, we carry out a site survey to verify the proposed building specifications and submit a proposal for implementation. The customer uses the proposal to order material. A team of four then replaces the old beam radio with the new technology, working simultaneously on two installations.  

3. How big is the project?
300 links per year, i.e. we convert around 550 installations per year.

4. Special assignments?
Stations in the mountains that are difficult to access are always a special challenge, especially as two or more teams have to work together simultaneously on different installations.  

5. What characterises W+A in this project?
We are extremely flexible, our project management is customer-oriented and we have an unbeatable First Time Right rate, i.e. fantastic installation quality.  

6. Impact on the daily life of Joe Public?
The performance of the entire network improves when communication between individual mobile telephone stations is faster and more stable. Customers notice a better network coverage, higher bandwidths and faster handover.

7. A look ahead to the future …
The entire network runs on E-band beam radio (around 50% of our current installations are E-band links). Perhaps beam radio will one day be as fast as fibre optic cable.
