How to Avoid Costly Emergency Repairs by Performing Proactive Maintenance in 4 Simple Steps
By Ramon Morales, NOC Operations Team, US
It’s 2:30 AM Saturday morning and the phone rings dragging you out of a deep sleep. Groggily you answer the phone and a voice at the end of the line is alerting you that the communication system is in alarm and traffic is down. While trying to figure out what’s going on, you remember you are the person responsible for your company’s communication infrastructure.

Microwave radio choices
There’s no one-size-fits-all in microwave. Each radio architecture comes with tradeoffs, so you need to weigh the choices in each segment of the network to get the right product mix for your business. To determine your best solution, first establish your requirements from a capacity, reliability, operational, and cost perspective. Then choose the right product. Microwave’s major technologies include the following.

5 Things You Should Know About RSL
By Ramon Morales, NOC Operations Team, US
Do you remember the last time your blood pressure was checked? I remember staring at the results wondering what the numbers meant. Usually my thoughts are, “Great, does this mean I’m healthy or should I be concerned?”
Recently, one of our customers had a similar experience with an email received from our customer service group. The customer’s initial impression was that the content received was vague and meaningless. “What am I supposed to do with this information?”, the customer asked.

State-Wide Microwave Network Case Study: Extra High Power Radios
This large western US state had a longtime relationship with a microwave radio vendor and would have continued buying from them if their radios and support evolved with the State’s needs. However, over time its needs changed and it had to have more capabilities from its communications network. But it did not want to unnecessarily build new sites and erect costly new towers.

Read More
Recently, the longest microwave link (189 km) ever turned up in a public mobile phone network went live in Tonga. It’s part of operator Digicel’s Pacific network. Engineers at Aviat Networks thrive on challenges. We go farther for our customers—in products, service and distance. For example, Aviat Networks previously implemented a very long all-IP backhaul connection across 193 km of open water in Central America for a private network application.
Case Study: When Extra High Power Can Reduce Need for Space Diversity
When designing microwave networks, backhaul engineers have a wide variety of techniques at their disposal. One method that remains highly effective is Space Diversity (SD). With SD, two antennas separated by some distance can increase the availability of a link from something less than 99.999 percent to in excess of five-nines uptime. However, the introduction of a second parabolic antenna on a microwave path poses a substantial increase in the capital expenditure (capex) budget.

4 Steps to Make Cisco Routers Microwave Bandwidth Aware
Cisco routers remain the backbone of internet connections worldwide. Deep in the heart of networks, core routers perform the essential plumbing of the web. Further out on the edges, access routers provide connectivity for mobile devices via microwave radios (many of which are Eclipse radios from Aviat Networks). Generally, routers assume a full 1 Gbps bandwidth capability between Layer 2 connections provided by microwave radios.
However, modulation and channel size selections can vary the actual bandwidth between 1 Mbps and 1000 Mbps (i.e., 1 Gbps). This can also happen when Adaptive Coding Modulation (ACM) is activated on a point-to-point microwave link and the link’s bandwidth varies based on propagation conditions. If congestion occurs on the link, the router cannot quickly prioritize traffic nor select the optimal path, resulting in possible “black holing” of critical traffic.

Getting it Done! Aviat & Australia Public Safety Networks
The public safety market has relied for many years on Aviat Networks to be a supplier of mission-critical microwave backhaul equipment. For example, since the introduction of the Eclipse microwave radio a few years ago, it has been received very successfully in the Australia public safety market. In the last five years, Aviat has sold and deployed thousands of radios (i.e., TRs) in the public safety and life critical radio ecosystem.
“The cutting-edge Gigabit Ethernet and IP capabilities of Eclipse were critical for Australia government agencies,” says Raj Kumar, vice president, sales and services, Asia Pacific, Aviat Networks. “As radio sites rolled out across Australia, Eclipse has enabled efficient deployment of multiple radio carriers in a single chassis—a mission-critical advantage for the simulcast trunking sites.”
