The Future of Backhaul is Now

There is an old saying in some places with words to the effect that “the future is now.” We believe the future of mobile backhaul is microwave and that future is now. At the risk of stretching the point of a seeming paradox, let us explain. The focal point for much of Mobile World Congress 2011 will be on Long Term Evolution (LTE) 4G cellular services.

Even with all the hype for LTE, its demand on the backhaul network will probably not exceed 200Mbps, and it will likely settle somewhere in the range of 150Mbps to 200Mbps for the typical LTE macro cell site. This figure is well within the throughput capabilities of modern IP/Ethernet microwave backhaul radios. We will be explaining more about this at our MWC courtyard pavilion #CY08 in the Fira de Barcelona during the week.

For a more detailed look at what Aviat Networks has planned for the week, let us elaborate. Aviat Network presenters will outline the company’s vision for the future of backhaul networks, focusing on the key challenges faced by mobile service providers around the world including:

1. 4G/LTE Backhaul—A Dose of Reality. The requirements for 4G/LTE backhaul capacity are being overhyped, leading to operators wasting potentially billions of dollars by running fiber to cell sites. Understand how microwave is exceeding the true backhaul capacity needs of 4G/LTE with high reliability—and much more cost effectively.

2. Simplifying Mobile Backhaul Evolution. The evolution of mobile network infrastructure to all-IP is potentially risky and complex, giving operators many confusing options. Learn how Aviat Networks is developing solutions that will help simplify and lower the cost of this evolution.

3. Small Cell Backhaul—Challenges and Opportunities. There is a growing consensus in the industry that operators will need to deploy a new “underlay” network of small, micro-base stations to provide the needed capacity and coverage for 4G. Find out how microwave is uniquely positioned to provide the backhaul for this new class of base stations.

In addition, you can see the latest Aviat Networks microwave solutions, which we will be introducing in person at MWC:

4. Aviat WTM 3000. A fully functional Carrier Ethernet transport node in a true zero-footprint package, the WTM 3000 includes for the first time advanced radio, modem and Ethernet networking functions all in a compact outdoor unit, unlike other “all-outdoor” packet radios that require an indoor unit or a separate switch/router to provide important networking advanced radio features.

5. Eclipse IDU GE3. An ultra-compact indoor unit (IDU) that combines the very latest Carrier Ethernet networking and advanced radio features for hybrid TDM/Ethernet or all-Ethernet/IP wireless transmission. The Eclipse IDU GE3 enables the deployment of cost-effective wireless tail-end cell-site connections and standalone point-to-point links.

6. Eclipse DAC GE3. A new plug-in interface module for the Eclipse Packet Node platform, theDAC GE3 provides the most advanced Carrier Ethernet switch subsystem available in microwave backhaul today. Featuring higher capacity and an impressive breadth of new capabilities, this third-generation design sets a new benchmark for resilient wireless access and aggregation networks.
