First, we add intelligence to proven technologies like Orthogonal Frequency Divisionemploy a unique combination Multiplexing (OFDM), Adaptive Modulation, and Dynamicof technologies that offers up Frequency Selection. Then we optimize the individualto 99.999% availability in highly technologies to work at maximum efficiency with ourchallenging environments and systems.extreme weather conditions. Every effort has been made to ensure that our radios canIn communication paths achieve the highest possible throughput for the givenwith challenges such as high interference conditions. As an example, our preamble-freeinterference, obstructions, water, communications maximize your throughput by eliminatinglong-distance hops, and brutal the time overhead required during transmissions. Such breakthrough engineering delivers the high level of capacity,weather events, our PTP 500 and signal quality, spectral efficiency, and performance that our600 systems are often the only customers have come to expect from our that can connect reliably.Such performance excellence is MULTIPLE-INPUT MULTIPLE-OUTPUTunique in the wireless broadband (MIMO) Non-line-of-sight (NLOS) and other challengingworld where 95% availability or environments create all kinds of signal distortion issues.“good enough” is often the norm. Connections are subject to massive periodic fading, often dropping to 1/10,000th of the already highly attenuatedPTP 500 AND 600 SERIES SOLUTIONS level. Because there is no main path and just many indirectOur PTP 500 and 600 radios are high-throughput, secure, paths of similar energy, signals are prone to be out-of-carrier-class solutions that are cost-effective, quick to phase. This dramatically raises the risk that signals willdeploy, and easy to manage.

At power-up and throughout operation, PTP 500 radiosIn challenging path conditions, signals arrive by many sample the band up to 400 times a second, while PTP 600different (dispersed) paths. Because path lengths vary, the radios sample the band up to 1,200 times a second. Bothsignals also arrive at different times. In addition, the paths radios dynamically select the frequency over which theyhave different delay characteristics, causing previously can sustain the highest data rate at the best quality.

Channel available for use Channel currently in useStandard OFDM separates data into channels which overlap Channel with high level of interferencein frequency. Orthogonal to each other, the channels donot interfere with each other, resulting in better spectrumefficiency and higher data throughput.

This enables your transmissions to travel from one receiver to the next without signal loss. The radio’s modulation mode is dynamically modified according to OFDM transmits data on multiple frequencies, resulting in the received signal level, upshifting or downshifting to greater resistance to interference and signal fading. overcome fading.

This allows you to collocate multiplethe same tower or rooftop or where a large number of links radios on a rooftop or tower while greatly reducing theare installed in a sizeable, dense network configuration, it very possible that the performance or throughput of someof the links can be reduced. This reduction in performance Radio-1 Radio-2 Radio-3 Radio-4is caused by cross interference between the collocated Radio-5 Radio-6radios. Cross interference occurs when transmit and receive All Allframes are unsynchronized, meaning that some radios Transmit Timeline Receiveare transmitting while their neighbors are receiving. Ourinnovative interface design makes our PTP 500 and 600radios more tolerant of cross interference.As an example, if Radio-1and Radio-5 are transmitting when Synchronized TDD with Greatly Reduced Cross Interferenceradio-3 is receiving, radio-4’s incoming transmission can beinterfered with even if the transmissions are on differentfrequency channels. Because the signals from Radio-1 and PTP 500 and 600 radios include TDD synchronizationRadio-5 are so close, they are strong enough to “flood” or technology which introduces a fixed TDD framing mode andinterfere with the communications flowing to radio-3. allows frame timing to be synchronized with other PTP 500 and 600 radios or an external Global Positioning SystemRadio-1 Radio-2 (GPS) timing module.

The PTP-SYNC Self-Interference receives a time signal from a clock source, sends the signal Unsynchronized TDD with Significant Cross Interference. to the PTP radio, and maintains synchronization between collocated radios when timing is unavailable, as can occur if a satellite goes off-line for a period of time.

This interference cancause the signals to cancel each other as they travel to 20 dBthe receiver from various directions over multiple paths. 1/100thIn addition, signals can experience ducting as they movethrough air masses of different densities, which deflectthe signals away from the receiving antenna, often cuttingcommunication between radios.In these situations, spatially diverse antennas, or vertically 30 dBseparated antennas, can be deployed at one or both ends 1/1,000thof the link. The spatially diverse antennas transmit overtwo radio paths to the receiver, so that the paths do notexperience reflection and ducting at the same time. Byoptimally combining the separate transmissions, our PTP500 and 600 radios can eliminate signal cancellation andmaximize the signal received in each direction. 30 – 40 dB 1/1,000th to 1/10,000thSpatial diversity combats ducting and multipath fading viavertically-separated antennas at one or both ends of a link. 40 dB 1/10,000thBEST-IN-CLASS RADIOSSignal attenuation occurs when natural or man-made Our PTP 500 and 600 radios maximize system gain and,obstacles in the path reduce the radio signal.
