Sunrise Communications, the second-largest mobile operator in Switzerland, has decided to deploy RAD’s Service Assured Access (SAA) solution to guarantee its customers’ high performance services.
With three million subscribers nationwide, Sunrise offers fixed-line, IPTV, and internet access, as well as business and IT services to enterprises, in addition to its mobile offerings, which include LTE and LTE-Advanced (LTA-A, or 4G+). Much of this IP traffic is transmitted over microwave, which adds latency and jitter and can result in packet loss. To address that problem, Sunrise sought a flexible, cost-effective performance monitoring solution that would ensure quality of service (QoS) across all network segments and guarantee end-to-end quality of experience (QoE) for its customers.
Sunrise selected RAD’s performance monitoring overlay solution as an add-on to its existing network.
RAD’s performance monitoring (PM) solution is comprised, among other elements, of PM controllers, which monitor and collect data on network traffic and service quality using various protocols, including both versions of TWAMP, as well as the patented MiNID, a field-programmable miniature Carrier Ethernet and IP network interface device (NID), which functions as a remote high-precision testing probe.
The PM controllers were deployed at Sunrise’s central sites, where they collect performance monitoring data. The MiNIDs were placed at intermediate measurement points and multiple eNodeBs, where TWAMP support is not otherwise available. This allows all elements throughout the network to quickly match their testing capabilities.

The RAD solution allows us to constantly monitor service performance and solve issues before they turn into problems that affect our customers. For detected issues, we are able to segment the problematic service path, measure the performance on each segment and in this way quickly identify the root cause.
Frank Mobius, RAD Sales Director for German, Austrian, Swiss and Nordic Service Providers
RAD’s SAA solution allows Sunrise to identify and segment performance degradation for its mobile and IPTV services. That is due to its deep visibility throughout the transport network, along with its intuitive graphs and reports that enable quick remedial action when and where it is necessary.
