In PART 1 of this blog, we provided an analysis of utility applications and expected capacity demands. Applications, especially security and surveillance, are rapidly increasing capacity requirements for utility networks. In this blog, we will outline an approach for performing capacity planning for a sample utility network in light of the applications traffic requirements.Read More
For many, Labor Day marks the end of summer vacations and children heading back to school. But this time of the year also includes potential severe weather threats for many states in the South and along the east coast of the United States.Read More
The tragedy of the commons happens when people sharing a common resource are inclined to overuse it, degrading it so much that becomes useless. An example is a field open to all in which cattle, have grazed for generations. At some point, a cattleman increases the number of animals of his herd to maximize profit.Read More
Opt-in or opt-out of the FirstNet plan is the biggest decision states will make about public safety in the coming years. Costs are critical, but states must ensure a sound architecture for mission critical communications. Whatever the opt-in/out decision, the advantages of microwave will play a huge part in the FirstNet network, and states will do well to follow these four recommendations:Read More
Aviat: The American Microwave Company and The Trusted Choice for State-Wide Microwave Networks
Aviat is the #1 provider of microwave and microwave routing systems to state/local government networks nationwide with 25 of 50 state-wide networks running Aviat equipment.Read More
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
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.”Read More
U.S. based state and local government backhaul buyers face a dilemma. Their microwave networks require continuous upgrades—now with the expectation that they become broadband capable—but their funding apparatus remains stagnant or even atrophies under fiscal pressures from citizens and policymakers. How can they obtain the next generation of wireless backhaul equipment vital to public safety and other purposes while doing so on a reality-based budget? The answer lies partly in an ongoing program that Aviat Networks can offer its government customers.Read More
In the last few weeks, the future prospects of small cell antennas got brighter and shrank at the same time. AT&T and T-Mobile both filed comments with the Federal Communications Commission (FCC) in support of an industry-wide waiver of rules against flat-panel antennas for backhaul radios in the 70-80GHz bands. Currently, out-of-date FCC regulations about antenna radiation patterns hold back development and deployment of this type of equipment that urban dwellers will find acceptable in big city cores.
The current rules effectively call for the use of parabolic antennas that will be unsightly and would violate the aesthetics considerations and zoning regulations in many city core locations—precisely the type of environment that 70-80GHz radios exist to service. While the FCC regulations seem to necessitate parabolic antennas to keep radio beams focused and from interfering with equipment in the vicinity that uses the same wavelengths, mobile subscribers prefer more visually friendly solutions.
How to get from here to there
For the last few years, Aviat Networks has been working with the Fixed Wireless Communications Coalition and others to get the FCC to update its regulations in the 70-80GHz bands. The problem: when the FCC promulgated these rules, the idea had never occurred to anyone that these bands would ever service small cell applications. And the applications that the FCC’s 70-80GHz rules were designed to support never materialized, with only 5,500 links registered in this spectrum since 2005, according to T-Mobile.
However, with this breakthrough in support from Tier 1 operators like AT&T and T-Mobile, the FCC should feel reassured that granting the waiver to the antenna rules for 70-80GHz bands is in the best interest of all the wireless industry service providers. And with OEMs in addition to Aviat asking for the waiver, no specific vendor will be favored. We urge other wireless service providers, communications equipment OEMs, subscribers and anyone else interested in moving forward as fast as the technology can go to also contact the FCC about granting this industry-wide waiver.

If you pay much attention to the mobile backhaul space, you may have noticed a big press launch this week by Ericsson and Cisco for a new partnership between the two tech giants. Both vendors will partner in the mobile backhaul space reselling each other’s solutions.
Analysts inside and outside the backhaul space have been hot to lodge their points of view on this combination. But as in William Shakespeare’s overused quote about “the sound and the fury” it might signify nothing. OK, that’s a bit of an overstatement, but there’s less here than meets the eye.
Don’t let the facts get in the way of a good ‘story’
Let’s take a look at the facts, as commonly understood in the industry. While Cisco is the 800 lb. gorilla in the IP networking room, when it comes to cell site routers it’s less than a 90 lb. weakling for microwave backhaul. Truly, Ericsson ranks high among microwave backhaul vendors, but its IP routers are not top-shelf offerings and leave much to be desired. You may think, well that was the point of the announcement: for Cisco and Ericsson to bolster each other’s relative portfolio failings by teaming up.
However, just as two wrongs do not make a right, a duo of less-than-optimal products cannot have the makings of a No. 1 contender. The shortcomings of both vendors’ kit are still present. Customers do gain the advantage of having one throat to choke, but they will just be choking the same throat twice as often.
Tried-and-tired method of microwave and IP
The underlying tried-and-tired method of using a different microwave radio and IP router in conjunction to solve Layer 3 issues in microwave backhaul still remains: individual devices living separate operational lives. Like a divorced couple staying in the same house, they may talk to each other when they must, but they don’t really like to. So, too, do microwave radios and IP routers have the ability to communicate, but they’re not designed to interact and honestly they’re not very good at it.
Which brings us to the inspiration for the integrated microwave router—the CTR 8000 platform from Aviat Networks. As we’ve made the case before, CTR 8000 microwave routers have been engineered from the ground up to function natively in both the microwave and IP communications worlds. The two technologies function seamlessly within one device. And existing as one piece of gear, a microwave router is easier to deploy and manage in the mobile backhaul network than a pair of randomly cobbled together radio and networking boxes.
In addition, with Aviat’s coded-for-microwave-networking software, ProVision, the leading network management system, admins at Network Operation Centers (NOCs) have full monitoring and management capability. They can see with minimal latency just how effectively microwave and IP activities are being carried out by CTR.
