More Net Bandwidth

By solving the hidden node problem, WORP® increases the overall net bandwidth of the multipoint system. Net bandwidth using WORP® can be higher than a standard Wi-Fi Access Point solution used in an outdoor environment. WORP® is a more efficient protocol that protects the system from packet collisions and transmits the data in an optimal way, which increases overall performance.

More Concurrent Subscribers

An outdoor point-to-multipoint solution based on 802.11 may connect from 5 to 10 remote nodes. In heavy traffic deployments, however, performance starts to suffer from collisions with as few as 2 remote nodes. A solution using WORP®, on the other hand, can connect over 100 remote nodes without adverse effects on usable bandwidth, allowing more concurrent Subscriber Units (SUs) to be active in a wireless multipoint environment.

Smart Scheduling

WORP® uses smart scheduling for remote node polling to avoid wasting bandwidth on nodes that have no traffic to be sent. The Base Station Unit (BSU) dynamically decides how frequently a remote node should be polled based on the current traffic to and from each remote node and the priority settings for that traffic. The scheduling is adapted dynamically to the actual traffic and further optimized by following the bandwidth limits as configured for each remote node.

Dynamic Data Rate Selection (DDRS)

DDRS enables WORP® to dynamically adjust the data rate at which the wireless traffic is sent. This feature is especially important in point-to-multipoint networks, when different SUs can sustain different data rates because of the different distances from the BSU. With DDRS, WORP® dynamically optimizes the wireless data rate to each of the SUs independently, keeping the overall net throughput at the highest possible level. This feature optimizes throughput even for links with different RF conditions on the BSU and SU, by optimizing downlink

Quality of Service

WORP® ensures that the most important data arrives with priority by differentiating between priorities of traffic as defined in the profiles for QoS (Quality of Service), similar to the 802.16 WiMAX QoS standard definition.

WORP® allows service providers to prioritize the traffic, allocating bandwidth based on the type of traffic. QoS is comprised of the following elements::

• Packet Identification Rules (PIRs), which classify the traffic
• Service Flow Classes (SFCs), which define priority, bandwidth, latency, and jitter for the traffic, and
• Quality of Service Classes (QoSCs), which define the SFC used for which traffic, classified by set of PIRs.

Bandwidth Control

WORP® allows service providers to control network bandwidth, protecting the network from excessive bandwidth use by any one station. Additionally, it allows service providers to differentiate their service offerings.

Asymmetric Bandwidth Controls
Asymmetric bandwidth gives network managers the ability to set different maximum bandwidth rates for a variety of customer groups. This allows service providers to further differentiate their service offerings and maximize revenues.
