Aperto Networks Proves In-Field Performance
of 5GHz Point-to-Multipoint Fixed Wireless Access Platform
Integrated systems approach supporting cell-based non-line-of-sight
Milpitas, Calif. January 17, 2001 Aperto Networks,
a developer of second-generation fixed broadband wireless access
systems, has announced its first alpha trial in a northern California
carrier network. Apertos system has been installed by a wireless
Internet service provider, using 5 GHz U-NII frequency spectrum.
Testing includes real-world conditions such as variable equipment
configurations, line-of-sight (LOS), obstructed line-of-sight (OLOS)
and non-line-of-sight (NLOS) locations, light-to-heavily loaded
network traffic, symmetrical voice, data and video transmissions,
and variable cell radii.
Apertos system uses adaptive Time Division Duplexing (TDD),
which is well suited for unlicensed band deployment because it provides
the flexibility to operate in a single 6 MHz channel anywhere in
the spectrum with data rates up to 20 Mbps. The companys multi-service
solution uses RapidBurstÔ, Apertos next generation dynamic
TDMA protocol, with embedded QoS and prioritization provisions,
that enables the upstream and downstream bandwidth allocation to
be dynamically adjusted to accommodate changes in traffic patterns.
This leads to dramatically improved performance in a heavily loaded
system, especially critical when time-dependent applications such
as voice and video are served over an IP network.
The alpha test, which commenced in December, also tests IP functions,
Network Address Translation (NAT), DHCP, routing, bridging and network
management, including Web based graphical user interfaces and SNMP.
We are delivering to our promise of rolling out a fixed broadband
wireless architecture for mass-market scale, said Reza Ahy,
Apertos president and CEO. We have developed, and now
deployed, a point-to-multipoint topology consistent with operational
carrier networks. The start of our alpha trials in Q4 2000, on schedule
and on target, marks the beginning of our market entry with a broadband
access solution that meets the requirements for second generation
systems for leading service providers.
Alpha testing is targeted for completion by late Q1. Apertos
end-to-end product architecture will begin extensive beta customer
trials in early Q2.
