Typically, low-latency microwave is used to “replace” traditional-fiber based networks linking financial centers. The business driver for microwave-instead-of-fiber in low latency is the time it takes to transmit trading instructions. With microwave, latency is reduced by a few milliseconds as compared to fiber. Nevertheless, those few milliseconds can translate into a trading edge over rival investors, which means big bucks. Low latency investors will pay a premium for this edge resulting in increased revenue for low-latency microwave network operators.
However, as with most financial functions, low latency is subject to a set of stringent regulations. The scenario is doubly difficult when low-latency microwave networks transmit across international boundaries. This compares to linking financial centers within a single country, which is relatively straightforward from a regulatory perspective because there is only one set of rules. The fact is when connecting financial centers in different nations and the operator’s network has to traverse other countries’ borders, the process becomes orders of magnitude more complex. Download the complete article for a fuller examination of some of these issues and why there should be widespread support for greater international harmonization of microwave regulation.

Are you considering building an ultra-low latency microwave network? Then you are not alone. Microwave is quickly becoming the default transport choice for low latency networks. However, building an ultra-low latency microwave network is not simple; there are many considerations. Latency through the “box” is important, but it is not the only factor, and too much focus on this metric may be a distraction. What is most important is end-to-end latency of the link. Aviat Networks recently addressed this topic in a webinar (registration required) and free presentation download and answered three very important questions regarding ultra-low latency microwave technology.
Also in this webinar, Travis Mitchell, Aviat Networks director of low latency business development, and Sergio Licardie, Aviat Networks senior director of systems engineering, consider the best practices for ultra-low latency microwave networks as they explore the techniques, technologies and design approaches necessary to ensure lowest end-to-end latency. They also discuss some innovations to look for in microwave networking to ensure continuous improvement in end-to-end latency performance. Other topics covered include:
- Main contributors to end-to-end latency of microwave networks
- Best options to reduce overall latency
- Strategies to avoid compromising overall availability

- Availability, Aviat Networks, Business, microwave, Reliability Engineering, technology, White Paper
This white paper was extremely popular when we featured it in our eNews newsletter recently. Now it’s time to share it with a wider audience.
It talks about how there are several considerations when establishing realistic outage or reliability objectives for and how the effects of long-term and short-term outages differ when it comes to microwave path engineering.

Managing Wireless Networks with Element Management Systems

An EMS can be thought of as managing all the elements in a complex network, keeping them all in balance. Image by michael.heiss via Flickr
Managing a wireless network is essential. Radios, routers and third-party add-ons control vast amounts of valuable user data. Any wireless network downtime damages the user’s business and the operator’s long-term reputation. Thus, operators need a powerful but easy-to-use element management system (EMS) to monitor and administer all the disparate elements in their wireless communication networks.
Also, operators should be able to manage complete networks from a user-friendly interface, which must provide all the necessary information for fast network management system decision-making. And this system must be capable of complete standalone operation or being integrated into an operational support system using NorthBound Interfaces (NBIs).
Other additional functionality in the form of event management and notifications capability is also necessary in an EMS for wireless networks. An EMS should inform wireless operators about network events and device failures and let them to diagnose problems and apply network updates remotely. This reduces the time between a fault occurring and the fault being repaired. It may even allow a repair to be completed before a wireless link fails completely. For day-to-day management, operators need an EMS that can:
- Deploy, manage and auto-discover wireless equipment—including all Aviat Networks devices, partner products and third-party devices
- Display an entire network at once, via one of several map views
- Provide an overview of network events
- Deliver notifications of important network events
- Enable analysis of network events, device events and performance data
- Generate detailed reports on all aspects of a network
The ProVision EMS solution can manage all Aviat Networks wireless solutions, partner wireless equipment and third-party devices from a user-friendly GUI.
Fortunately, such a carrier-class EMS solution does exist. Aviat Networks develops its ProVision EMS based on customer demand and continues to upgrade it as per user requests and requirements. For customers, implementing ProVision is vastly more efficient than developing an in-house EMS, saving time, resources and money. Aviat Networks EMS solutions are the most cost-effective way to manage wireless solutions. Aviat Networks works closely with customers to make sure that ProVision is user-friendly. The goal is that ProVision EMS allows operators to manage their networks proactively—rather than reactively—and with reduced network operating costs.
Look for future blog posts on must-have EMS data features and stats on operators using carrier-class EMS.

Evolution of Microwave: History of Wireless Communications

This image of microwave energy in a "total sky" picture of the known universe shows it's everywhere in primordial space, more than 13 billion years ago.
Microwaves are as old as the beginning of the universe. Well, they’ve been around for at least 13.7 billion years—very close to the total time since the Big Bang, some 14 billion years ago. However, we don’t want to go that far back in covering the history of microwave communications.
Having just observed the 155th anniversary of the birth of Nikola Tesla, arguably the most important inventor involved in radio and wireless communications, this is a good time to take a broader view of the wireless industry. If you have been in the wireless transmission field for some time, you are probably familiar with Dick Laine, Aviat Networks‘ principal engineer. He has taught a wireless transmission course for many years—for Aviat Networks and its predecessor companies.
The embedded presentation below comes from one of those courses. In a technological field filled with such well-educated scientists and engineers from some of the finest universities and colleges, it’s hard to believe that microwave solutions and radio itself started in so much controversy by men who were in many cases self-taught. Dick’s presentation goes over all of this in a bit more detail. Hopefully, it’s enough to whet your appetite to find out more. If you like the presentation, consider hearing it live or another lecture series on wireless transmission engineering at one of our open enrollment training courses.

Antennas: Why Size is Important for This Wireless Equipment

In response to the recent FCC docket 10-153, many stakeholders proposed relaxing antennas requirements so as to allow the use of smaller antennas in certain circumstances. This is an increasingly important issue as tower rental costs can be as high as 62 percent of the total cost of ownership for a microwave solutions link. As these costs are directly related to antenna size, reducing antenna size leads to a significant reduction in the cost of ownership for microwave equipment links.
The Fixed Wireless Communications Coalition (FWCC), of which Aviat Networks is a major contributor, proposed a possible compromise that would leave Category A standards unchanged while relaxing Category B standards. The latter are less demanding than Category A, and after some further easing, might allow significantly smaller antennas. The rules should permit the use of these smaller antennas where congestion is not a problem, and require upgrades to better antennas where necessary.
A further detailed proposal from Comsearch proposed a new antenna category known as B2, which would lead to a reduction in antenna size of up to 50 percent in some frequency bands. This would be a significant cost saving for link operators.
At the present time, the industry is waiting for the FCC to deliberate on the responses to its 10-153 docket, including those on reducing antenna size.
