Public safety agencies will soon experience a dramatic improvement in communications capabilities enabled by advances in technology. New broadband multimedia applications will give first responders and commanders alike far better situational awareness, thereby improving both the effectiveness and safety of all personnel charged with protecting the public.

The specific technology, now mandated by the U.S. Federal Communications Commission (FCC) for all new emergency communications networks, is Long Term Evolution, or LTE—a fourth-generation (4G) broadband solution. The FCC has also allocated licensed spectrum to ensure the best possible performance in these new networks. These FCC rulings support the goal of achieving an interoperable nationwide network for public safety agencies.

The FCC chose LTE based on its proven ability to support voice, video and data communications at remarkably high data rates that were previously only possible with wired links. Although there will be some differences in a nationwide public safety network involving capacity and coexistence with Land-Mobile Radio communications, lessons learned from LTE’s deployment in large-scale commercial mobile operator networks will help ensure agencies are able to achieve the FCC’s goal cost-effectively.

What to Expect from IWCE in 2012

As you know, IWCE (International Wireless Communications Expo) is just around the corner (Feb 20-24 Las Vegas) and is the premier event for government, public safety, utilities and transportation.  We are excited to be exhibiting once again at this event.

We can expect to hear about 2 key themes:

1. Public Safety migration to LTE
The introduction of LTE technology into public safety networks is happening now and represents a huge change for state/local agencies.  LTE is a brand new technology for this market and represents a new way of thinking for many folks.  LTE brings new services and applications, different network planning and design assumptions, more capacity requirements, and more IP traffic.  Understanding how to build microwave networks that best support the cost, capacity and mission critical requirements of public safety LTE will be key to building mission critical LTE data networks.  Aviat has unique solutions to solve these complex challenges.

2. Security of critical infrastructure
The current and ongoing migration of public safety networks toward IP/LTE is increasing the opportunities and motivations malicious activity. As the amount of critical data rises in the broadband public safety network, security has become of greater concern.  This will be a key topic at the show.  Again, Aviat has a unique strong security solution which we’ll be talking extensively about at IWCE.  In fact, in addition to the exhibition, we will be speaking on a panel at the IWCE show regarding cyber threats to the public safety network infrastructure on February 23rd at 3:30 – 4:45pm which we would like to invite you to attend.

Please check back after the show for an update on how things went!!

Nathan Hitchcock, NOC team lead for Aviat Networks, provides guidance for all network services professionals in the company’s network operations center during its 24×7 rotation. At the NOC, Hitchcock describes a range of customers the company services—from Internet service providers to public safety networks (government wireless) . “Our customers find value in the NOC,” he says.

“It’s a natural progression that once the network is live, that the NOC just take over the managed services aspect of it,” Hitchcock says. “We provide value to our customers by helping reduce the operational expenses that are associated with managed services.”

When Aviat Networks moved its NOC to San Antonio, Texas, many backbone infrastructure and wireless security improvements were made, according to Hitchcock. And all the technical knowledge was transferred from Raleigh, N.C. He sums up the Aviat Networks’ network services value proposition as: a multi-disciplinary team that provides managed services to meet the clients’ needs.

Microwave Wireless Backhaul Case Study: Tooele County (Utah)

In an all-indoor configuration, Aviat Networks’ Eclipse Packet Node platform has delivered flexibility to Tooele County, Utah, to transition its partially mountainous, rural legacy TDM network to IP when the traffic demands it. When greater functionality is required, the modular nature of the platform is called upon to ease installation and maintenance.

“The entire design is highly modular, and we are able to drop in new network cards with the latest technology. We just swap new cards for old,” says Dave Williams, communications manager for Tooele County. “So not only does Eclipse Packet Node provide native TDM support for our latency-sensitive, mission-critical traffic today but also allows us the flexibility to migrate to native all-IP traffic as our applications evolve. With this platform, we get the best of both worlds.”
