Proxim Wireless’ advanced suite of dynamic and adaptive Radio Frequency technologies ensures high spectrum efficiency with minimal error rates in high density environments and under challenging interference conditions.
DDRS (Dynamic Data Rate Selection)
DDRS enables Tsunami® systems 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.
Small Channel Size Support
Channel bandwidths of as low as 5 MHz and 10 MHz are available to maximize the usage of available spectrum.
Flexible Center Frequency
The operating channel center frequency can be set in 1 MHz step to ensure the radio link is using the cleanest spectrum available.
ATPC (Adaptive Transmit Power Control)
Enables Proxim radios to adjust transmit power to achieve desired link Signal to Noise Ratio but no more which avoids pumping maximum power into the environment potentially causing self interference as well as noise to other unlicensed systems. ATPC is also used to ensure that the radio properly follows local Equivalent Isotropic Radiated Power (EIRP) rules.
HARQ (Hybrid Automatic Re-transmission Request)
ARQ, or Automatic Re-transmission Request examines packets at the PHY layer and request a resend of any damaged packets. Hybrid ARQ ensures this only takes place with data packets, avoiding any additional delay from ARQ being introduced to latency sensitive traffic such as voice.
Proxim has invested over fifteen years of continuous development and wireless expertise to create our Wireless Outdoor Routing Protocol known as WORP®. WORP® is a reliable, secure, and highly efficient protocol that guarantees delivery and optimal performance with Quality of Service controls, supporting quad play applications on a single wireless network such as mobility, video surveillance, VOIP and other delay sensitive multimedia applications. WORP® also helps ISPs control bandwidth and differentiate service offerings with the ability to enforce SLAs. Learn more about the WORP® advantage here.
WORP® Sync is a TDMA (Time Division Multiple Access) based implementation of Proxim’s WORP, which eliminates co-location interference. With WORP® Sync, all BSU’s transmission and reception are time-synchronized by means of GPS one pulse per second signal. This mitigates the co-location interference and improves the overall performance of the network.
Satellite Density setting helps to achieve maximum bandwidth in a wireless network. It influences the receive sensitivity of the radio interface and improves operation in environments with high noise level. Reducing the sensitivity of the device enables unwanted “noise” to be filtered out

ACS (Automatic Channel Selection)
An indispensible installation tool, the automatic channel selection feature works during network booting and allows Proxim’s radios to determine the best channel with the least inference.
DCS (Dynamic Channel Selection)
This feature monitors the retry percentage in a given radio link. If retries exceed a set threshold, then it dynamically searches for a new channel with less interference.
