Three Elements to IP/MPLS Success in the Microwave Access
- January 23, 2017
- Aviat, Aviat Networks, AviatCare, AviatCloud, backhaul, Carrier Ethernet, Ethernet, IP/MPLS, LTE, Microwave backhaul
In microwave communications—as in all electronic communications mediums—operators trend toward the latest technologies (e.g., IP/MPLS). They all have conditioning to think that newer is better. And by and large that’s right.
However, when it comes to IP/MPLS—one of the most advanced packet technologies—you need to handle this concept with care. Especially in a mixed infrastructure that includes microwave, fiber and other potential backhaul transport.
E-Band Global Regulation Roundup

Because of need for higher capacities, the trend toward shorter link distances for mobile backhaul and declining product costs, 70/80GHz (i.e., E-band) solutions are gathering significant interest for mobile backhaul and enterprise access applications. However, because these frequencies are new to most people, there is little understanding of costs and other issues related to licensing the 70-80GHz spectrum.
Simplifying Carrier Ethernet Networks Scalability and Operations

As symbolized at the recent EANTC interoperability testing event, Aviat microwave radios can help solve the complexity and scalability problems of Carrier Ethernet technology.
Carrier Ethernet (CE) transport networks are growing in both scale and complexity, requiring both vendors and operators to deliver solutions to sustain their growth. To help address this, Aviat Networks recently participated in the European Advanced Networking Testing Center’s (EANTC) annual multi-vendor interoperability testing event to validate several aspects of scaling CE networks, among other things.
Increasing CE network sizes increase the complexity of management—especially from a services perspective—when CE services span multiple network domains. The ability to partition management domains and effectively manage alarms that accurately identify and propagate notification of network faults, dramatically speeds up the fault isolation and resolution process across large networks. Utilizing and effectively implementing “Hierarchical Service OAM” in growing CE networks is valuable to overcoming this challenge and was a key area of the recent interoperability testing.
Another critical aspect of growth is dealing with multi-technology—not just multi-vendor—interoperability. As CE networks scale, there is an increasing mix of Ethernet switching, MPLS and, most recently, MPLS-TP internetworking emerging. One potentially complex area that was also tested was validating the operation and survivability of intersecting Ethernet and MPLS-TP rings in a multi-homed topology. The “ERPSv2 and VPLS Interworking” test validated that standards-based G.8032 Ethernet protected rings and MPLS-TP VPLS rings can interoperate, or more significantly “co-operate,” to allow complex multi-technology networks to deliver reliable end-to-end services.
To learn about these aspects of scaling and dealing with complex CE networks check out the EANTC white paper for more details.

Aviat Advanced Microwave Networking Seminar: DC Style
- September 21, 2012
- Carrier Ethernet, Commscope, Dick Laine, microwave networking, National Telecommunications and Information Administration, Principal Engineer, product marketing, Quality of service, Stuart Little, Tellabs
The Microwave Networking seminar hosted by Aviat Networks in Washington D.C. in Sept 2012 had a large turnout of attendees who listened to speakers present on wireless security, MPLS, Carrier Ethernet and other topics of interest to the backhaul community.
Aviat Networks recently completed the latest in its Technology Seminar series on microwave networking with a two-day event in the Crystal City area of Washington D.C. One observer noted attendees were particularly interested in hearing more about security of wireless backhaul systems and how to make a choice between using IP/MPLS or Carrier Ethernet.
The seminar was packed to capacity with more than 100 attendees from organizations that included various federal government agencies, utility companies, public safety organizations and mobile operators. These seminars focus solely on issues relevant to microwave deployments, related technology, regulatory issues, and deployment considerations—with no product pitches.
Attendees took advantage of an agenda that covered a wide variety of technology topics, including microwave-focused sessions on capacity, Ethernet QoS and OAM, IP/MPLS, security and strategies for lowering the total cost ownership of microwave networking. The highlight of the seminar was again Dick Laine, longtime Aviat Networks principal engineer, who spoke at length about Microwave Path Engineering and designing links using Adaptive Modulation. Dick is one of the foremost authorities in the U.S. on microwave planning and path design, and some attendees travel long distances just to hear him speak and share his experiences of more than 50 years in the microwave networking business. (If you’ve never heard/seen Dick present, register for his free Radio Head Technology Series).
Aviat Networks also welcomed special guest speakers from the NTIA, Comsearch, CommScope, Tellabs and LTI DataComm who graciously contributed their time and effort to provide a deeper understanding for attendees on their topics of expertise.
Keep a lookout for details of the next Technology Seminar that may be coming to a city near you! Or if you would like to be notified directly when our next microwave networking seminar is scheduled, please complete this form.

LTE – Lessons Learned So Far
- February 14, 2012
- 3GPP Long Term Evolution, backhaul, Carrier Ethernet, Internet Protocol, microwave
Aviat Networks has been deploying LTE networks for well over a year now to operators globally, including the largest live commercial LTE network in operation today. So, it’s probably a good time to reflect on some key observations and lessons learned to date. Here are the top 3 things we’ve learned from our LTE microwave backhaul deployments that are most notable:
1. LTE backhaul capacity needs are being easily addressed by packet microwave:
– When it comes to capacity there is a perception that fiber is the only answer. The reality is that based on current LTE deployments, 50Mbps is more than adequate for most LTE cell sites today. Yet, for comfort and long term growth most of our customers are licensing and deploying 100-200Mbps of microwave capacity to their LTE equipped cell sites. For intermediary sites that aggregate traffic, link aggregation techniques are being utilized to effectively bond multiple channels for higher capacities, all well within the multi Gbps reach of advanced microwave systems, such as ours.
2. Ease of deployment and fast time to market (TTM) are critical for success:
– This LTE operator quote speaks volumes regarding the real challenge he faces: “Whoever can deliver the quickest with the least amount of pain will win most of the business”. TTM is most crucial for operators trying to stay one step ahead of their competition… more markets served, better coverage etc. To address this, we have seen a growth in our customers seeking a one stop shop approach for LTE microwave backhaul deployment where we engineer, configure, test, and deploy the full end–to-end system, providing overall project management, frequency coordination, installation and a host of other services. The fact that most microwave systems can be installed in a few weeks as opposed to months for fiber, is also playing a key role in microwave growth in areas like North America where microwave penetration is low, but growing as a result of LTE rollout.
3. Backwards compatibility with multivendor interoperability is key:
– It’s all about LTE, right? Well, yes and no. LTE is driving the new investment and deployments, but the reality is that 2/3G will be around for a long time. So, while the new deployments are driven by all-IP LTE, there are still ‘legacy’ T1/E1s still hanging around that also need to be backhauled. This has been a perfect fit for Aviat’s all-in-one Hybrid (TDM+IP) and All-IP microwave systems, which allow our customers to easily software configure their mix of traffic. So, while the bulk of the transport bandwidth is provisioned for IP to support LTE, some is still reserved for good ‘ole TDM.
– Another related aspect is multivendor interoperability across a variety of product types. The backhaul market has flourished in the last few years as we know, and so has the variety of cell site switches, routers, packet optical devices etc. that our microwave systems interoperate with to fulfill our customers ‘end-to-end’ LTE backhaul solution. Consistent Carrier Ethernet standards applied across both the microwave and fiber core makes this very straightforward when it comes to provisioning Ethernet backhaul services, supporting packet network synchronization, and managing these services.
So, in summary, I would say we’ve learned that packet microwave is well suited for LTE capacity needs; it can be rapidly and easily deployed; and provides great flexibility for legacy services and multi-vendor interoperability. But the best proof of all this is in our customers’ live networks.

Wrap Up of Carrier Ethernet World Asia Pacific
- December 7, 2011
- Aviat Networks, Carrier Ethernet, Singapore
This year Carrier Ethernet World (CEW) Asia Pacific (APAC) took place from Nov. 30 – Dec. 2 at the Resorts World Convention Centre in Singapore. Around 320 delegates attended; most were local operators. However, there was representation from other APAC countries, in particular Malaysia and Indonesia.
Aviat Networks was the sole microwave radio solutions provider at the event and Steve Loebrich, Director Product & Solutions Marketing, spoke on the subject of “simplifying the network to enable high capacity services”. It was interesting that the Chinese vendors did not attend.
The main theme of the event was cloud computing and how can it generate additional revenue for operators. Another hot discussion topic was synchronization and its challenges. Most operators in Asia prefer 1588v2 due to its simplicity in implementation; however some operators have chosen to implement both 1588v2 and sync Ethernet in their network.
Unlike previous years there were no debates on MPLS traffic engineering technology to adopt VPLS, T-MPLS or MPLS-TP etc. This year, the major operators were advocating not to build overly complex networks offering next generation services. As an example, one major operator has chosen to adopt PBB in its access layer for corporate services.

This month we have a few technology updates from our travels abroad to London and Amsterdam where we presented our perspectives on backhaul at two LTE conferences.
In May, Stuart Little, our director of global corporate marketing, presented at an LTE backhaul conference organized by Telecom IQ in London. Stuart hosted a workshop that focused on the current challenges faced by mobile service providers while preparing their backhaul networks to meet the demand of next generation LTE broadband services. Comprising an intimate crowd of mostly operators, the conference focused on a series of operator presentations, panel discussions and roundtable conversations. Representatives from operators such as BT, Telenor, France Telecom, Telecom Italia, Vodafone, Mobitel and Saudi Telecom were in attendance. Some key issues discussed focused on the backhaul needs of LTE, which are difficult to predict. With a few exceptions, most LTE deployments to-date are limited or in the trial phase. Operators are also grappling with a mix of technologies in their networks, making migration to all-IP a huge and complicated task.
While in London, Stuart also spoke at the 13th annual Transport Networks for Mobile Operators (TNMO) Conference on May 10. TNMO is one of the largest conferences in Europe focused purely on backhaul transport networks. This year, Aviat Networks participated by presenting on the topic of “Realistic Capacity Requirements for LTE,” or why fiber is not the only answer, and took part in a panel discussion on Carrier Ethernet for mobile backhaul. The conference was fairly well attended, with a packed agenda that covered the full range of transport challenges from the access to the core. Numerous solutions to the problem of delivering more capacity to meet expected demand were discussed, including network sharing, microcells, network offload and intelligent backhaul optimization techniques. It seems that there is no single winner in the race to find a solution. Operators are going to have to choose from an array of options to get the right fit for their particular needs.
Over in Amsterdam, Peter Croy, our senior IP network architect, presented on the topic of Carrier Ethernet for LTE mobile backhaul requirements at the LTE World Summit. Not sure if you have read previous blogs or joined in our webinars on this subject, but Peter is a well versed expert on backhaul. See his overview from the conference.
With summer fast approaching and vacations looming, June will be a bit slower. Good thing as planning will begin for some major events and shows coming in the fall and early 2012.
An event you won’t want to miss is the 1588v2 Synchronization for Mobile Backhaul Networks Webinar on June 6. Hosted by Patrick Donegan, senior analyst at Heavy Reading. This webinar will bring together leading vendors and operators to develop best practice guidelines for operators as they deploy the 1588v2 standard. Drawing on real implementation case studies, industry leaders will demonstrate where some implementations have gone wrong in the past and what leading operators and vendors are now doing right to deploy this key standard. Please join us for this highly interactive webinar. The webinar is co-hosted by Errol Binda, our very own solutions marketing manager.
Another interesting event is the National Urban Areas Security Initiative Conference (UASI) conference held in San Francisco, June 20-23. This conference is in cooperation with Department of Homeland Security, Federal Emergency Management Agency and the Grants Programs Directorate. The conference will provide an opportunity for stakeholders from all areas of homeland security and emergency preparedness to gather and exchange important information to make the United States safer.
We will have a booth, No. 85 in the Continental Ballroom, at the conference where we will display our public safety solutions along with showcasing all-indoor configurations of Eclipse Packet Node. Ali Hirsa from Aviat Networks will be at the booth to answer any questions you may have.
That’s it for now. I will be back in touch next month to update you on the latest happenings at Aviat Networks. Until then, follow the dialogue and news on our social sites.
