In Australia, the federal government has had an ambitious plan to connect all citizens to a national broadband network (NBN). However, in some of the more remote parts of the country, of which there are more than a few, the incumbent provider, Telstra, cannot deliver that subscriber experience. This leaves it to alternative access providers to fill the gap.
One of these providers, Aviat partner MIMP Connecting Solutions, decided to use Aviat Networks microwave solutions to reach remote customers beyond the NBN fiber footprint. This is important as many vulnerable subscribers need to be connected to doctors, nurses and other healthcare professionals for help. Literally, this can be a matter of life or death.Read More
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.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
In late January and into February 2016, a big tumult ensued when Sprint announced that it would begin to move its mobile backhaul strategy from one based on leased fiber to another based on owned microwave radio. The story first ran in technology news site Re/code and quickly got reposted with additional commentary by FierceWireless, Wireless Week and others, and which was reiterated this week in RCR Wireless.
While the breathtaking headlines about reducing costs by $1 billion caught most people’s attention—primarily through reducing tower leasing costs and not using competitors’ networks—lower down in the copy came a potent reminder from Sprint about the economic benefits of microwave radio. It also highlighted the fact that backhaul has entered a transitional period (see article end for more on that).
Most of that $1 billion that Sprint seeks to save comes by way of moving away from AT&T and Verizon fiber backhaul networks. You might think that Sprint would build its own fiber network instead. But that would take too long and still have an exorbitant price tag associated with it. It’s a function of both out-of-pocket capital costs and embedded lost opportunity costs. Bottom line: laying fiber connections is expensive and slow. Putting up a network of high-speed, broadband microwave relay towers is quicker and easier.Read More
Just this February, Ncell, the leading mobile provider in Nepal, awarded Aviat Networks an Appreciation Certificate for successfully migrating its existing VSAT network to high-speed Eclipse microwave radio. This project was executed in the Himalaya range at an average attitude of 4,410 meters above sea level with three passive repeater links. Included in this rollout is a 99 km microwave link.
According to Ncell, this is the world’s highest 3G rollout. As a result, this upgrade is considered a feather in Ncell’s hat.
While Aviat Networks has completed many successful projects with Ncell, this one is worth a special mention. Awarded in 2013, this project has helped Aviat establish itself as a key Ncell vendor for the access network. The implementation includes equipment and services.Read More
LTE mobile connectivity now exists in many more urban places than not. Virtually all big cities have multiple choices for LTE and most have at least one choice for LTE Advanced—the real 4G wireless. For example, you can see iPhone and Android users taking advantage of all this high-capacity coverage as they leisurely view high-definition YouTube videos without buffering and actually livestream major league sports in cafes, parks and just walking around at lunch.Read More
In Austria, people love their coffee, and they love their Internet. WLAN provider NETcompany makes sure they get both, with high-speed wireless access via hotspots at cafés and other popular places with the help of microwave networking.
Serving a core business clientele of home and business customers, NETcompany offers wireless Internet connections in fixed applications. In addition, the company builds and provides wireless Internet access points, also known as wifi hotspots, to cafés, hotels and other mostly tourism-related establishments
Around two years ago, Aviat Networks began working with the wireless Internet service provider to connect its point-to-multipoint base stations, which aggregate the business and residential wireless traffic, to its main communications infrastructure via a backbone based on Eclipse microwave radios. In addition, hotspot traffic is also transported over the backbone network.
Apparently, business has been increasing over the course of time. Thus, more advanced networking services and higher capacity are required to keep up with wireless Internet demand from the customers of NETcompany’s customers.
Therefore, NETcompany became interested in the Layer 2 capabilities of the CTR 8540 and its more robust Carrier Ethernet features. In addition, the higher QAM modulations supported by the CTR 8540 enable higher airlink capacities for aggregating traffic than are available in traditional microwave radio. Now the WLAN provider’s backbone is supported by a series of CTR 8540 microwave routers that deliver high-capacity backhaul capability.
This early CTR 8540 customer is already deploying high-capacity links in 2+0 configurations. Aviat continues to work with NETcompany and other customers with vertical applications. Read about other early CTR 8540 scenarios and let us know about your microwave networking application.[contact-form-7 404 "Not Found"] Read More
Since the beginning of October 2014, there has been a lot of coverage in the technology press concerning the so-called “Shellshock” or “Bash Bug” computer vulnerability. All the coverage has been exclusively related to general IT and computer systems. But how does this vulnerability concern microwave radio systems? Take our poll and let us know what you know.
Aviat Networks recently completed an exhaustive internal review of all our current and legacy products and found no inherent weaknesses in any of the systems toward Shellshock. We have recently informed our customers of this end result (see statement).Read More
Recently, telecom research firm Heavy Reading conducted a survey of mobile network operators (MNOs) from the around the world exclusively for Aviat Networks. The goal of the survey was simple: determine the sentiment of MNOs to provide fixed wireless services to enterprise customers.
Now that the growth rate of individual wireless subscribers has leveled off in many nations with mobile penetration rates near and even exceeding 100 percent, MNOs have begun to look very seriously at alternate sources of revenue growth. And one of those alternatives is fixed wireless enterprise services, which according to Heavy Reading, MNOs rank as a co-strategic priority along with their core subscriber business.
Enterprise services are all very well and good but how does an MNO deliver them? The answer is not as complex as you may imagine but somewhat more difficult in reality. While MNOs have robust infrastructure based on rock-solid microwave backhaul technology to the cell sites at the edges of their networks in the majority of cases, they do not have an easily deployable method of supporting fixed wireless services to enterprises. One such way would be via Layer 3. In the survey, Heavy Reading found that a supermajority, or 70 percent, of MNOs believe that Layer 3 (L3) capability from the cell site is “critical” or “very important” to enable new service delivery.
However, L3 capabilities are not the end of the story. Layer 3 services are packet-based and require IP/MPLS routing functionality in order to operate. Accordingly, the MNOs surveyed by Heavy Reading reflect this outlook by an overwhelming 75 percent stating that IP/MPLS is “critical” or “very important” for offering fixed wireless services to enterprises. In addition, 75 percent of MNOs also believe it is “critical” or “very important” that existing cell site equipment be made capable of delivering these fixed wireless enterprise services. The existing cell site equipment is quite capable of delivering Layer 2 (L2) fixed wireless services, but help is needed to go the next step up to L3.
“Whilst L2 can be used to deliver business services, our survey results suggests that most mobile operators are very interested in the additional benefits of L3 including MPLS,” says Patrick Donegan, senior analyst, Heavy Reading. “They also tend to value very highly the ability to deliver those business services from existing equipment at their cell sites.”
Donegan goes on to elaborate further in the complete survey results where he reveals more eye-opening insights. To find out these and more click here.
