Technological Innovations
At the heart of PacketWave's revolutionary performance are three innovative Aperto
Networks technologies:
RapidBurst™
,
OptimaLink™
, and
ServiceQ
™ .
RapidBurst
RapidBurst
technology enables the PacketWave System to achieve exceptionally low
latency and high spectral efficiency. Advanced Time Division Multiple Access
(TDMA) burst mode ensures maximum flexibility and efficiency in both upstream
and downstream transmissions. Adaptive Time Division Duplexing (TDD) allows
operation in a single channel anywhere in the spectrum. Dynamic bandwidth alloca-
tion assigns time slots and packet sizes depending on specific traffic flows. With
RapidBurst
, the PacketWave System provides up to 120 Mbps of bandwidth per cell
with one base station.
OptimaLink
OptimaLink
technology individually optimizes the reliability and throughput of each
Subscriber wireless channel by dynamically adjusting up to ten PHY- and MAC-layer
parameters. The result is increased coverage, extending broadband services to
subscribers who would otherwise be unreachable due to obstructed-line-of-sight or
non-line-of-sight conditions.
ServiceQ
ServiceQ
technology provides different quality of service (QoS) levels to subscribers
on a flow-by-flow basis enabling differentiated service offerings and effective man-
agement of service level agreements (SLAs). Various service levels can be defined in
three service classes—Constant Bit Rate (CBR), Committed Information Rate (CIR),
and Best Effort (BE). The percentage of bandwidth allocated to each service class is
adjustable depending on the mix of service offerings.
ServiceQ
supports high-quality video and telephony applications. Each service flow
can be associated with a specific host or application and can be assigned to any service
class, so application-specific services with QoS can be offered.
