The Growing Challenge
As spectrum becomes more crowded and technologies like Wi-Fi 6E proliferate, interference and misconfigurations are no longer rare. Even well-behaved devices can create additive interference, and seemingly healthy links can mask packet loss or congestion. For decision-makers, this means higher operational risk and potential revenue loss.
Why Traditional Monitoring Falls Short
Traditional Network Management Systems (NMS) often present a false sense of security. They may show all links in a “green” state as long as they are minimally communicating, hiding underlying degradation.
Conversely, NMS platforms can flood teams with alarms and raw data without providing actionable insights. In large networks, this leads to longer Mean Time to Repair (MTTR), higher costs, and frustrated customers.
The risks fall into three primary categories that chip away at your network’s health:
1. Sporadic Interference
The growing prevalence of unlicensed 6 GHz devices (like Wi-Fi 6E) can cause periodic, unpredictable interference in the licensed spectrum. This subtle noise can compound across multiple devices, leading to degraded customer performance that is nearly impossible to spot manually.
2. Mis-provisioning and Hidden Congestion
Configuration errors, such as incorrectly set queues or thresholds, can cause intermittent packet loss and congestion that traditional alarms simply miss.
3. Data Overload
Modern equipment generates massive amounts of performance data—potentially millions of data points per link per year. This makes it impossible for human staff to manually triage and identify the most critical issues.
The Solution: From Data Overload to Actionable Intelligence
Aviat’s Health Assurance (HAS) and Frequency Assurance (FAS) tools transform network management. Instead of reacting to outages, these tools analyze millions of KPIs, detect anomalies early, and pinpoint root causes—without requiring deep microwave expertise. Purpose-built by microwave engineers to address these unique challenges, HAS and FAS transform mountains of raw data into immediate, actionable intelligence.
Health Assurance Software (HAS)
Key Function:
Analyzes and correlates link performance data (Utilization, Congestion, Propagation Anomalies). Provides a probable root cause and likely next steps.
Business Impact
Real-time Network Health: Delivers two critical business values.
- Early fault detection and proactive maintenance, helping you address potential issues before they impact your customers.
- Provides clear visualization of link utilization trends, empowering your team to make informed, just-in-time capacity upgrade decisions.
Together, these capabilities reduce troubleshooting time, minimize service disruptions, and support efficient network growth
Frequency Assurance Software (FAS)
Key Function:
Analyzes high-resolution Paperless Chart Recorder (PCR) data to detect and identify the source of RF interference (e.g., bursty Wi-Fi 6E vs. steady external radio).
Business Impact
Spectrum Protection: Protects your investment in expensive spectrum by maintaining optimal link performance. Enables proactive intervention before customers experience outages.
Key Benefits for Your Business
Implementing ProVision Plus with HAS and FAS delivers tangible, measurable business benefits :
- Reduced Operating Costs (OpEx): Automate complex troubleshooting, lowering the reliance on a large team of expensive, highly experienced microwave radio engineers.
- Optimized Capital Expenditures (CapEx): With “just-in-time” capacity upgrade planning based on actual utilization trends.
- Maximized Network Availability: Enable proactive resolution and identify issues before they become outages, increasing network uptime and availability.
- Faster Response & Resolution: Technicians arrive on-site with a focused understanding of the problem and the necessary tools, leading to a dramatic reduction in repeat visits (truck rolls).
Investing in assurance tools is not just about troubleshooting; it’s about shifting your network operations from reactive crisis management to proactive health monitoring and strategic capacity planning.
Bottom Line
Silent killers don’t announce themselves—but they can erode your ROI. Consider Aviat HAS and FAS if you would like to see the following benefits applied to your network:
- Faster Resolution: Reduce MTTR with actionable insights.
- Lower Costs: Minimize truck rolls and reliance on specialized engineers.
- Improved Reliability: Detect interference and congestion before they impact service.
- Capacity Planning: Trend analysis for smarter upgrades.
