What Does it Take to Get the Most out of Your Wireless Backhaul?

Wireless backhaul operators, both mobile phone networks and others carrying dedicated traffic, face the constant issue of maximizing the functionality of their systems.

In the emerging markets around the world, the pressure can be most intense. Wireless network reliability, availability and capacity all need to be increased. Customer expectations are on the rise, and operators must take the appropriate steps to meet and exceed them.

In working with MTN Ghana, Aviat Networks recently completed an implementation to increase network visibility (i.e., intelligence) by close to one-third. Aviat’s professional services experts designed the mobile operator’s backhaul links for high capacity and resiliency. Using ProVision, Aviat’s leading network management software, MTN Ghana can now administer its wireless backhaul efficiently and effectively with a reduced level of manpower.

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.

Aviat Networks Training Center for Wireless Network Services

At the Aviat Networks full-service training facility in Santa Clara, Calif., Patrick Davis, director of global support services for Aviat Networks, discusses the numerous offerings that the site can provide. Bringing customers into a closed environment such as the Santa Clara facility allows them to focus on learning the technologies and theories behind microwave wireless backhaul, he says.

We sit down with the customer without distractions outside the office and go over the entire wide portfolio of end-to-end services we offer, Davis says. We cover everything—from IP theory to microwave theory to pathloss to transition from TDM, he says. Product training is on Aviat Networks equipment and other vendors’ devices, such as those from Tellabs.

Would You Like Breakfast? User Interface Design Choices for Wireless

Image via Wikipedia

If you are not from the U.S., the number of choices you need to make simply to order breakfast may overwhelm you. Contrast that to my experience staying at a bed and breakfast on a trip to England: I was asked only two questions—both with a choice of “yes” or “no.” Breakfast and Tea. If you are in a foreign country, jet-lagged, hungry and a little parched (thirsty) there is some comfort in being able to simply say “yes” and “yes.”

Having a choice is good but only if you know what you are choosing. If you are in unfamiliar territory, it can be overwhelming to have to choose whether you want Ranch, French or Vinaigrette. Particularly, if you thought that French and Vinaigrette were the same thing. Conversely, it is very disappointing if you want your bacon extra crispy, but you are not given that option.

Challenge of New and Experienced Users

In the world of user interface (UI) design, the challenge is to cater to new users who do not yet understand the choices they can make and at the same time make sure experienced users—who know exactly what they want—have the control they need. For example, the Eclipse DAC GE3 has been a huge challenge to provide a simple and consistent user interface and at the same time provide control over the advanced Ethernet Switch features.

Rolling up groups of settings into default, canned and custom configurations has allowed us to seamlessly provide simple and advanced views. For VLAN configuration, we provide familiar DAC GE “mode of operation” settings for Transparent, Mixed and VLAN (GE and ES compatible) along with a new 1-to-1 mapping of ports to channels. Clicking on them allows you to create and name custom port groupings and selecting Advanced allows full control of the switch behavior.

We also use many diagrams to make it easier to see at a glance how the switch is configured and to help visualize what the settings mean. The VLAN settings are rendered into a small diagram that shows canned, custom or advanced VLAN configuration in a consistent manner.

The challenge of making our user interface universally accessible is ongoing, and we will continue to improve our user interface over time. And I will continue to enjoy my full English breakfast with a hot cup of tea.
