Company enhances 9500 Microwave Packet Radio for the North American market with new all-indoor version, support for additional ANSI frequency bands and increased system gain

Alcatel-Lucent (Euronext Paris and NYSE: ALU) has enhanced its microwave packet radio portfolio for the North American market with additional features and support for additional frequency bands to better address the needs of mobile service providers as they deal with the data increase caused by the rapid growth of high-bandwidth interactive consumer applications. The new release of the Alcatel-Lucent 9500 Microwave Packet Radio (MPR), which is part of Alcatel-Lucent’s comprehensive mobile backhaul portfolio, provides more flexibility in terms of radio frequency planning, support for longer range transmissions and increased efficiency to support service providers’ transformation to all-IP, and the introduction of Long Term Evolution (LTE) mobile data services.

Microwave packet radios are high-bandwidth wireless transmission systems used to interconnect 2G, 3G and LTE cellular base stations between each other and the fiber metro network. At each hop they aggregate any type of traffic (TDM, ATM and Ethernet) and then transport it to a concentration point on the fiber metro network.

The 9500 MPR meets mobile backhaul transformation requirements by providing a fully scalable platform addressing trunking, last mile and aggregation applications for both TDM and pure Ethernet base-stations. With these enhancements the 9500 MPR extends the supported ANSI frequency bands to include 10.5 and 11 GHz. The addition of the 10.5 and 11 GHz bands provides an efficient alternative to 6 GHz by relieving frequency congestion, enhancing overall network availability and reducing tower lease costs. Additionally, higher transmit power options are introduced into the 6 GHz band allowing the use of smaller antennas or longer path distances, significantly improving the flexibility of network designs for mobile operators. These features, coupled with the all-indoor design allow operators to deploy microwave backhaul with zero tower climbs for operation and maintenance.

The 9500 MPR offers a variety of features that are unavailable in traditional microwave platforms, including: service-driven adaptive modulation, DS1 and DS3 in packets via pseudo-wire/CES (circuit emulation services), multi-service aggregation, long haul full indoor transceivers, short haul split mount transceivers, and Ethernet synchronization distribution. These features enable the migration from TDM to packet and provide operators with a flexible and cost efficient solution for data hungry applications

“The operators who have started the migration from existing connectivity to packet-based backhaul are discovering the limitations imposed by a hybrid microwave solution,” said Francois Allain, head of wireless transmission activity within Alcatel-Lucent Optics. “The 9500 MPR overcomes these limitations by providing the flexibility to handle multiple traffic types and mobility generations at the same cell site, on the same infrastructure, and to cost-effectively support new services for new revenue generation.”

Live Network From Edge Access to Aggregation/Core Features Company’s Extensive Carrier-Class Product Portfolio for Mobile Operator Networks With Any Combination of 2G to 4G Technologies

Exalt Communications, the company that is reinventing microwave backhaul, will demonstrate at CTIA this week a live, hybrid TDM/IP end-to-end microwave backhaul network for mobile operator transport infrastructures from edge access cell sites to the aggregation and core networks. The LTE-ready network features the company’s extensive carrier-class product portfolio across multiple physical configurations, frequency bands, microwave transmission technologies and native TDM/IP traffic mix, for mobile backhaul applications with any combination of 2G, 3G and LTE. The demonstration network consists of three edge access links aggregated via a hub aggregation node and then backhauled to one high capacity TDM/IP core aggregation node.

“We understand the issues mobile operators are facing as they try to cope with ever-increasing subscriber demand for data against flat subscriber revenue,” said Amir Zoufonoun, president and CEO of Exalt Communications. “Success will depend on building out a network at a lower cost per bit that can support high bandwidth from edge to core, with pay-as-you-grow functionality and easier migration from TDM to IP. Our live demo is a microcosm of the very networks mobile operators are trying to implement, and we welcome the opportunity to share our approach in our booth at CTIA.”

The live demonstration features end-to-end connectivity for Ethernet, including 64-byte packet performance, DS3 and T1 across the entire network over a common, managed microwave communications infrastructure, as well as migration from TDM to full IP/Ethernet by re-allocating capacity from TDM circuits to Ethernet. Migration can occur on the mobile operator’s schedule and in the sections of the network where it is most required.

Edge Access Cell Sites
At the edge, Exalt will feature the latest ExtendAir™ zero-footprint microwave backhaul radios, supporting native TDM and native Ethernet, in 18 GHz FDD and 5 GHz CarrierTDD™ for CDMA/GSM/3G or 4G/LTE base station interconnection, and providing 100 Mbps of full-duplex capacity and up to 4xT1/E1/. The edge demonstration will also feature an Exalt 6 GHz Gigabit Ethernet system to demonstrate how a full DS3 can be transported with 140Mbps of full-duplex Ethernet capacity and additional T1s over a long haul, high power link. This link will also feature Exalt’s unique 1.5+0 semi-protection for remote edge access locations.

Aggregated TDM and Ethernet Capacity
The hub aggregation node interconnects all native Ethernet and native TDM traffic from the edge access links and any traffic from cellular base stations at the aggregation node itself into a high capacity, aggregated backhaul interconnection to the MSC/POP. Exalt split-mount Gigabit Ethernet systems provide a direct connection for all Fast Ethernet and Gigabit Ethernet layer 2, DS3 and T1 traffic from the edge access sites without the need for an external layer 2 switch or TDM cross-connection devices.

At the Core
The core backhaul interconnects the aggregation hub to a core aggregation node via a multi-band Gigabit Ethernet aggregated link with over 500 Mbps full-duplex Ethernet (non-compressed, layer 2, 1536-byte packets) and nearly 700 Mbps full-duplex at layer 1 (64-byte packets). The same link carries 1xDS3 and 16xT1 TDM traffic as well, demonstrating that TDM legacy and 4G/LTE base station traffic can be delivered over the same high speed, high performance core backhaul infrastructure, thus keeping costs low and availability high.

To further boost capacity-handling capability, Exalt Gigabit Ethernet systems include built-in state-of-the art data compression technology designed to deliver up to 3x more throughput per carrier, depending on traffic profile. This results in link capacities of up to 1 Gbps full-duplex per single carrier (layer 1, 64-byte packets) and 4 Gbps in the maximum capacity aggregation configuration. To demonstrate enhanced availability, Exalt will showcase the use of errorless and jitterless adaptive modulation that can be deployed over hybrid TDM/Ethernet links to extend range, optimize availability by traffic type and adapt throughput to changing path conditions.

Carrier-Class Systems Deliver 100 Mbps Ethernet for Student Records, Other Administrative Applications in Suburban Chicago School District

Exalt Communications, the company that is reinventing microwave backhaul, today announced that Maywood School District 89 in suburban Chicago has deployed its EX-5r-c and EX-5i microwave radio systems to enable a 100-megabit per second (Mbps) Ethernet network that serves 5,500 K-8 students at multiple locations.

The District’s facilities include schools in Maywood, Broadview and Melrose Park, Illinois. The microwave network carries traffic for approximately 1,200 computers located at schools, a data center and district offices. While the district has used microwave radio links since the late 1990s to handle administrative applications and e-mail, it has recently upgraded its network with Exalt microwave radio systems to triple the available bandwidth, reduce management overhead and improve overall reliability.

“Our previous microwave radio systems limited us to about 30 megabits-per-second and we had to call in our consultant whenever we needed a configuration change,” said Bob Hodges, director of technology at Maywood School District 89. “With the Exalt systems, we have 100 megabits on tap and we can use their excellent management interface and built-in spectrum analyzer to adjust frequency bands or handle other maintenance activities.”

The Exalt systems were deployed on the recommendation of Wireless Information Networks (WIN), an RF engineering, design, deployment and management firm in nearby Burr Ridge, Illinois. “Given the numerous interference sources present throughout the school district, the Exalt radios’ interference mitigation capabilities were the key features that allowed our engineers to design a reliable, carrier-class backhaul network for Maywood School District 89,” said Thomas Pedergnana II, senior project manager at Wireless Information Networks.

WIN deployed EX-5r-c radio systems as a backbone that connects the district’s data center in Melrose Park with two key schools, and then it added EX-5i radio systems to link four other school locations. The average network hop distance is one mile. Thanks to the additional capacity available, the district has now implemented new applications such as video surveillance on its network.

“We like the ability to add applications as needed without worrying about whether the network will handle it,” said Hodges. “In fact, we can go to 200 Mbps with a simple license key upgrade — that’s a really great concept.”

With their simplified management, the EX-5r and EX-5i Series radios allow Hodges and his team to perform most routine maintenance themselves, saving the cost of calling in WIN consultants for a site visit. In addition, all Exalt radio systems deliver 99.999 percent link and throughput availability, making them much more robust than the previous systems.

“Schools across America are using computerized applications not only to improve the educational process, but also to improve safety through video surveillance,” said Amir Zoufonoun, president and CEO of Exalt Communications. “Like other school districts we serve, Maywood Schools has reduced its costs and improved its ability to educate students efficiently and safely by deploying our high-capacity, high-availability radio systems.”

All Exalt radio systems — licensed and license-exempt — are carrier-class systems offering guaranteed link availability, guaranteed throughput and low, constant latency. Systems are available in frequencies from 2 to 40 GHz and in capacities from 10 Mbps to more than 700 Mbps per channel, providing a range of options to fit countless network applications. Designed to enable a smooth transition to IP, they offer native support for both TDM and Ethernet, and are fully software configurable and upgradeable. For easy and secure management using third-party network management systems, Exalt systems support SNMP v1, v2c and v3. Data security is provided by available FIPS 197-compliant AES 128-bit and 256-bit encryption that adds zero latency to the transmission. To simplify installation and maintenance, all Exalt systems feature an embedded manual and most include a built-in spectrum analyzer.
