3 Models for Microwave Link Error Performance? Laine Explains

Dick Laine explains ITU-R models

In the second episode of Aviat Networks’ Radio Head Technology Series, Principal Engineer Dick Laine explains ITU-R models for Fixed Wireless Systems.

As most radio engineers know, Vigants calculations, which are discussed in a broadly cited Bell System Technical Journal article, are widely used to determine reliability or error performance for microwave link design. In Video 2 of Aviat Networks’ popular Radio Head Technology Series, which is now available for viewing, Principal Engineer Dick Laine explains how he uses Vigants calculations in conjunction with the three completely separate ITU-R Fixed Wireless System (FWS) models for TDM.

Because of all these models, he likes to use Vigants calculations as a “sanity check” to see that he is close to the correct result for his path engineering plans. The free Aviat Networks’ Starlink wireless path engineering tool can be used to handle Vigants calculations for Aviat Networks’ and other vendors’ equipment.

Can’t wait to hear more of Dick’s experienced views on microwave radio transmission engineering? You can get ahead of the learning curve by registering for the series and get these videos sent to your inbox as soon as they are released.

Cloud Computing is Demanding Bandwidth

All I can say is watch out Mr. Mobile Operator. Google just launched their new Google Drive, a cloud-based product that replaces Google Docs. Drive adds the capability to essentially push all of your documents from various locations to the cloud for collaboration and synchronization to any device. This puts Google’s cloud-based capability on par with Apple’s iCloud service launched last year.

With the massive number of smartphones on the market and somewhere north of 45% being Android-based, this adds even more cloud-enabled devices to the mobile network. We’re talking about photos, videos, documents, etc… any type of file can be uploaded to your Drive on Android-based phones.

Add this to expanded/simplified Dropbox services, Microsoft’s SkyDrive that now provides 7GB of free storage and the many cloud storage products, and you’ve got a ton of data flowing across the mobile network in both directions (e.g. uplink and downlink).

Services like this will continue to fuel the subscriber appetite for more and more feature rich services at the same time fueling demand for ever increasing amounts of raw bandwidth all the way to the edge of the network. Those 8 megapixel photos or 1080P videos most newer smartphones take use a lot of space and therefore lots of bandwidth.

National Association of Broadcasters (NAB) Show 2012

NAB 2012NAB 2012 was extremely well attended by both vendors (all three exhibition halls were fully occupied) and participants. Thanks to the continuing conversion from analog to digital broadcasting, TV companies are investing heavily in equipment and software solutions. Every company was presenting digital solutions from cameras to studio equipment to TV transmitters to Microwave Radio transport.

Every facet of the solution set must be upgraded to accommodate the intricacies of digital networks. In the case of the Microwave Radio, they are moving to bi-directional radios that can not only carry the studio content up to the transmitter site, but also can carry collected content from various mobile generating platforms (trucks, helicopters, etc) back to the studio for editing.

It was interesting to see Cisco, HP and other networking companies exhibiting. The integration of Internet Protocol (IP) into the broadcasting community has created a real demand for networking appliances like routers and switches. Other devices like Microwave Radio must also be able to accommodate IP protocols for efficiently carrying the video content to the various transmitters in the network.

I was amazed at the range of nationalities represented. Clearly this show offers value to broadcaster across the globe. I heard a figure of over 400 people from Brazil attended the show. I think I heard people complain about their tired feet in 25-30 different languages! The combined attraction of NAB and Las Vegas is very difficult to pass up.
See you at NAB 2013.

Managed Services for Emerging Markets – Dubai 2012

This time last week, we were participating in the Managed Services for Growth Markets conference in Dubai. The conference consisted of two days of presentation and panels discussing the latest trends in Managed Services for emerging markets. We heard how several customer organizations have leveraged Managed Services to improve performance, costs, and, ultimately, their bottom line.

This is similar to what we are seeing and hearing across our own customer base. There is a growing demand for wireless network services suppliers to take on more of the support and maintenance of networks. By outsourcing operational activities, our wireless customers can focus on perfecting the services they offer to their customers.

Our own Ross Gillett, Director of Services for the Middle East and Africa, participated on a discussion panel focused on how suppliers, such as Aviat Networks, bring value to their customers through Managed Services. Ross emphasized that specific knowledge of the local customer requirements is key in developing a successful solution. Whether it is a mobile service provider, low latency customer or a state agency—they are all basically looking for someone who can bring value to their investment.

The bottom line is that good partners focus on making their customer successful!

Emerging markets are an important area of focus for us and this particular event had strong support from a number of our existing customers as well as several potential new customers from these markets. We heard a number of presentations outlining some of the unique challenges customers and Managed Service providers have to address in this region. We also had a chance to speak with conference participants and share our experiences with managing multiple customer networks.

In our exhibition hall reception area, we had numerous opportunities to interact with suppliers, media and even competitors to share stories, challenges and where we see the market headed. These one-to-one conversations are the best part of a conference since it gives us an opportunity to share, on a personal level, how Managed Services are being leveraged on a broad basis.

We will definitely be returning next year.

Director, Global Support Services

Dick Laine’s 4 Keys to Successful Transmission Engineering of Microwave Links

Dick Laine, Principal Engineer, Aviat Networks

Dick Laine, Principal Engineer, Aviat Networks

Transmission engineering of a microwave link requires creativity and skill. So if you are looking for inspiration as well as high-quality wireless engineering instruction look no further than the “Radio Head Technology Series.” Radio Heads is a collection of videos and podcasts featuring our very own Dick Laine. Dick is arguably the most experienced microwave engineer in the wireless communication business, having spent more than 50 years working with microwave radio from its inception—here at Aviat Networks and our predecessor companies (e.g., Farinon, Harris MCD).

Dick has been involved with nearly every aspect of RF transmission, microwave link and network transmission design, and the effects of geoclimatic conditions on transmission of voice and now IP radio data packets.

In his own unique style, Dick has been teaching basic and advanced concepts for digital microwave transmission in seminars and training classes worldwide. Students who have taken his classes return years later eager to get a refresher from Dick and to hear about some of his great adventures in Asia, the Middle East, Africa and in the Americas.

In the first Radio Heads video titled “Check List for a Successful Microwave Link,” Dick explains the four key objectives or requirements for a well-done microwave link design along with “check list” items that the project manager or transmission engineer evaluates for proper design and deployment of a digital microwave link. If you have not already signed up for this video series, register to view the content.
