Aviat Networks introduced the Aviat WTM 3000 outdoor networked radio, a new class of product for wireless transmission applications. For the first time in a single radio, the WTM 3000 combines full IP/Ethernet aggregation and switching, along with the latest in advanced radio transmission features to maximize frequency efficiency and throughput. It includes all advanced radio, modem and Ethernet networking functions all in a compact, environmentally hardened outdoor unit.

Offering a wide frequency range that spans licensed frequency bands from 6 to 38 GHz – all with a common, fully outdoor architecture – the WTM 3000 represents a breakthrough in converged networking and transmission solutions. Incorporating the latest in carrier-class Ethernet switch technology and three Gigabit Ethernet ports, it supports nodal functions with aggregation, Carrier Ethernet Quality of Service (QoS) controls, Ethernet Operations, Administration and Maintenance (OAM) and IP/MPLS awareness. The WTM 3000 also provides superior radio transmission features, such as 256QAM Adaptive Coding and Modulation, excellent RF system gain performance, and support for link capacity-doubling, through co-channel operation with XPIC.

Moving inside, the company announced the Eclipse IDU GE3, an ultra-compact indoor unit that combines the latest Carrier Ethernet networking and advanced radio features for hybrid TDM/Ethernet or all-Ethernet/IP wireless transmission. Supporting link throughputs up to 400 Mbps, the IDU GE3 will provide more than enough backhaul capacity for the overlay of new 4G/LTE base stations. The Eclipse IDU GE3 enables the deployment of cost-effective wireless tail-end cell-site connections and standalone point-to-point links. In conjunction with the nodal site capabilities of the Eclipse Packet Node, the IDU GE3 optimizes backhaul cost and performance.

Delivering good spectrum utilization, comprehensive synchronization and low power consumption, Ceragon Networks’ FibeAir IP-10 E-Series is claimed to provide unrivaled wireless transport capacities and is optimized for mobile internet and broadband services in an all IP environment. With end-to-end Ethernet service management and sophisticated Operation Administration & Maintenance (OA&M) tools, the solution helps to simplify network design, reduces both OPEX and CAPEX and drastically improves overall network availability.

The FibeAir IP-10 E delivers up to 2 Gbps of IP traffic per channel. The solution also includes a number of industry-first features, such as the breakthrough asymmetrical traffic payload delivery, which enables it to increase download capacity in asymmetrical deployment scenarios.

Key features of the FibeAir IP-10 E-Series include, high capacity and efficiency at any channel bandwidth with proven optimization techniques for common mobile broadband traffic patterns, simplified network design and maintenance that reduces operators’ CAPEX and OPEX, a fully flexible synchronization solution and support of services with stringent SLA, as well as being optimized for current deployments with higher capacities and broadband services.

Dialogic Inc. launched a mobile backhaul optimization solution for service providers, the Dialogic® I-Gate® 4000 Session Bandwidth Optimizer Mobile Backhaul (SBO MB), which provides for voice and data stream optimization for 3G, 2G and enterprise traffic. The I-Gate 4000 SBO MB reduces OPEX through the consolidation and bandwidth optimization of voice and data traffic, thereby reducing transport requirements. By doubling throughput over existing backhaul links, the solution can also reduce CAPEX by eliminating the need to purchase additional equipment.

As the only 1U platform to provide full redundancy for hardware, software and network failures, the I-Gate 4000 SBO MB provides high reliability for customers. It supports a wide range of traffic types and interfaces, including IP and ATM-based iub, Abis, Native IP, VoIP, PCM signals and Pseudowire (TDM over IP). Topologies for both microwave and satellite transmissions are also supported, including point-to-point, point-to-multipoint, drop and continue, ring and data offload.

DragonWave’s introduction of Horizon Compact+ provides operators with a key tool to address lifecycle cost in three critical areas: spectrum utilization, capacity and location leasing costs. As the first all-outdoor system to incorporate Cross Polarization Interference Cancellation (XPIC) technology, Horizon Compact+ also takes advantage of XPIC’s spectrum-doubling capability. Building on the capacity increases from the company’s Bandwidth Accelerator technology, this spectrum-doubling capability increases the data bandwidth of Horizon Compact+ to as high as 2 Gbps.

Cost containment is another benefit. Leasing costs are a major capital expense for system operators, carriers and enterprises that support their own microwave capability. By integrating the modem and radio in the same robust outdoor system, Horizon Compact+ makes interior rack space available for other components and reduces rental expenditures.

DragonWave continues to implement its ‘building better backhaul’ focus for its customers. Pay-as-you-go scalability is built into all of the company’s Horizon products to protect hardware investments and grow capacity through software upgrades.

NEC Corp. exhibited the latest edition to its iPASOLINK series, the NEC iPASOLINK 1000, which is a converged, dual-native solution that supports both native TDM and native Ethernet transport on the same platform. This allows fixed and mobile operators gradual, cost effective migration to an all-IP backhaul, required for the transformation to 4G LTE and the cloud computing era.

The NEC iPASOLINK 1000 is designed for high-end aggregation sites in the network and complements existing NEC iPASOLINK 200 and 400 products, as well as previous generations of NEC equipment. It includes multiple microwave nodal aggregation, high switching speeds and an increased number of interface options including 10 Gbps Ethernet and Coarse Wavelength Division Multiplexing (CWDM). Single-chassis implementation eliminates backhaul aggregation and distribution bottlenecks by allowing optimum network design of both optical and microwave connections.

All products in the NEC iPASOLINK series provide flexible migration to full-IP at the best time for the operator and without the need to prematurely switch off legacy equipment since they support both existing TDM networks and future Carrier Ethernet networks on one platform. In addition, the NEC iPASOLINK series is managed by NEC MS5000 Network Management System, which provides streamlined management of radio, optical and IP networks. Auto-provisioning and end-to-end Quality of Service (QoS) management provide SLA assurance and reduce both time to revenue and maintenance costs.

Picochip announced the first in its next generation of picoXcell™ femtocell chips, the PC3008, which is optimized for high-volume cost-sensitive consumer applications. The PC3008 is the first in the PC30xx family of devices, the company’s third generation of femtocell (Home NodeB) devices, following the PC202 and the PC3xx series. It supports eight users with Release 7 HSPA+ (21 Mbps downlink, 5 Mbps uplink), and embodies Picochip’s field-proven robust PHY, already approved by many operators, reducing the risks and time-to-market for system developers.

It is manufactured using 40 nm process technology and features a fast (950 MHz) ARM11 processor with TrustZone®. Compared to previous SoCs it is said to enhance security functions and increase integration, reducing external component count and hence bill-of-materials. It also includes optimized support for next generation low-cost and low-power femtocell radios.

The PC3008 integrates the key components of a 3G femtocell into a QFN package just 12 mm square, enabling OEMs to produce smaller and more cost-effective femtocells. As a demonstration of the low power, small size and integration that PC30xx series devices will enable, Picochip showed an example of an HSPA+ femtocell in a USB dongle – the world’s smallest 3G base station.
