Cell Size, Capacity, and Scalability
Aperto’s advanced wireless technologies support a wide range of cell requirements,
and make PacketWave an exceptionally scalable solution. PacketWave cell specifica-
tions include:
• Cell radius can easily reach 5 miles (8 km) with line-of-site transmission paths,
or about 1 mile (1.6 km) with obstructed paths.
• Each Base Station Unit can support up to 250 subscribers per sector, with a
maximum of six sectors.
• A cell can employ multiple Base Station Units. Thus, a single cell can serve
thousands of subscribers.
• The bandwidth capacity for a Base Station Unit is 120 Mbps, based on a max-
imum raw bit rate of 20 Mbps per sector.
• Subscriber data rates can be individually configured from 384 kbps to 10 Mbps;
with bursts to 20 Mbps.
• The ratio of downstream to upstream traffic can be adjusted between 90%
downstream/10% upstream and 90% upstream/10% downstream.
The PacketWave System ensures that a wireless network can grow to thousands of
subscribers in urban or suburban areas through high frequency reuse and dense
multicell deployment. Combining high frequency reuse with advanced interference
management and mitigation techniques, the PacketWave System conserves valuable
spectrum by covering extensive geographical areas with a minimum number of
channels.
As the number of subscribers and the bandwidth needs in a cell increase, new sectors
can be added, and multiple PacketWave 1000 Base Station Units can be stacked to
provide additional bandwidth using multiple channels per sector. To extend service
offerings geographically, a service provider simply deploys additional cells.
Multiple Frequency Bands
The PacketWave System can be deployed in the standard frequency bands used vari-
ously throughout the world for licensed or unlicensed wireless broadband networking.
The PacketWave 1000 Base Station Unit can support PacketWave radios and antennas
operating in 2.5 GHz MMDS, 3.5 GHz FWA, 5.3 GHz, and 5.8 GHz U-NII bands
with no physical or software reconfiguration. Similarly, any PacketWave 100 Series
Subscriber Indoor Unit (bridge/router) can support the same range of frequency bands.
