Aperto Networks Announces PacketWave System for Fixed
Broadband Wireless Access
Innovative F-BWA Solution with Dynamic Per-Subscriber Optimization
for Multi-service, Multi-Cell
2.5, 3.5, and 5GHz Carrier Networks
Milpitas, Calif. February 5, 2001
Aperto Networks, a developer of second-generation fixed broadband
wireless access systems, today announced its scalable, point-to-multipoint
PacketWave family of base station, subscriber units, and associated
radios and antennas in 2.5, 3.5, 5.3 and 5.8 GHz frequency bands
for carrier networks worldwide.
Our market entry with PacketWave is the first step towards
Apertos mission of universal availability of broadband access,
emphasized Aperto CEO and president Dr. Reza Ahy. PacketWave
applies Apertos breakthrough technologies - RapidBurst,
ServiceQ and OptimaLink to give carriers real-world
multi-service network deployment solutions with scalable capacity,
coverage, and mass market cost-effectiveness.
PacketWaves performance features include
Advanced architecture maximizing carriers spectrum
utilization with high frequency reuse
Up to 20Mbps burst rates over a 6 MHz channel
Line-of-sight, obstructed line-of-sight, and non line-of-sight
coverage
Advanced interference mitigation and management for multi-cell
networks
IP-Based multi-service delivery in high capacity QoS-enabled
networks
Dynamic per-subscriber link optimization.
PacketWave Product Family
The PacketWave 1000 Base Station uses advanced TDMA and bi-directional
burst mode transmission to achieve the efficiency of bandwidth on
demand. Each Base Station is equipped with multiple wireless ports
and one 100Mbps Fast Ethernet network port. With plug-in modules,
each PacketWave 1000 supports a six-sector cell and OC-3/STM-1 backhaul
using ATM or POS. The Base Station is stackable for scalable capacity
and redundancy. Combined with innovative implementation of cellular
deployment and frequency re-use techniques, the platform enables
carriers to support over a thousand subscribers per cell and easily
scale up by adding channels.
The PacketWave 1000 Base Station is designed to operate with adaptive
TDD or FDD radios. Initial systems will be available with adaptive
TDD radios for 2.5, 3.5, 5.3 and 5.8 GHz bands. Optimizing the wireless
connection to each subscriber, OptimaLink dynamically adjusts up
to ten PHY and MAC-layer parameters, including antennas with spatial
and polarization diversity, modulation, power allocation, retransmission
policy and frame size. This ensures that the wireless connection
to each subscriber has the optimal throughput and reliability. In
addition, the coverage area is expanded to reach subscribers previously
inaccessible due to obstructed-line-of-sight or non-line-of-sight
conditions.
PacketWave 100-series subscriber units support between 1 and 200
hosts or individual users, are SNMP-manageable, and include both
a compact indoor unit with Ethernet 10/100 interface and a frequency
specific integrated radio/antenna unit for 2.5, 3.5, 5.3 and 5.8
GHz bands. Highly modular and user-installable, the units come configured
for up to five users (PacketWave 110) with bridging capability,
up to 20 users (PacketWave 120) with bridging and network address
translation (NAT), and up to 200 users (PacketWave 130) with bridging,
NAT and routing.
Apertos product offerings include highly scalable element
and subscriber management tools to monitor, configure, and provision
the system and deliver multiple services. New subscribers are provisioned
in minutes using the JAVA based WaveCenter Configuration Manager.
Multiple service flows are supported per subscriber, using highly
flexible subscriber profiles that work in conjunction with Apertos
ServiceQ. This gives service providers the ability to offer granular
levels of service and bandwidth guarantees appropriate to specific
customer applications.
"Aperto's new systems appear to offer the ultimate in flexibility
for carriers to configure new wireless networks that integrate with
legacy architectures, while migrating them to second-generation,
more powerful and cost-effective F-BWA," observed Paul Kellett,
senior director -research of Pioneer Consulting, a leading global
broadband telecommunications market analysis firm.
General availability for global markets will commence by mid-2001
for all four sub-11GHz frequencies.
