Which word best defines success in wireless connectivity? Is it
availability? Reliability? How about speed?
Consider this: 85% of properties 457 metres (1500 feet) apart have no optical line-of-sight path between their roofs. For them, a conventional wireless solution wont work 75% of the time. Motorolas PTP 400 family of point-to-point wireless solutions succeeds over 99% of the time.

Operating in the 5.8 GHz, 5.4 GHz and 4.9 GHz frequencies, the Motorola PTP 400 Series wireless Ethernet bridges (formerly Orthogon Systems OS-Gemini) succeed where more conventional solutions disappoint. The systems achieve highly reliable connections, much more often and at faster data rates than comparable wireless solutions because the radios can maintain as high as 99.999% availability in challenging environments. Even in supposedly connection-friendly applications, PTP 400 solutions protect against the transient attenuation, fading and dispersion that degrade all wireless signals. (It is recommended that regulatory conditions for radio-frequency bands be confirmed prior to system purchase.)

Incorporated in Motorolas MOTOwi4 portfolio, the PTP 400 wireless Ethernet bridges offer several models to meet a variety of customer requirements:

Integrated: Integrated versions of the PTP 400 bridges include built-in antennas. The 5.8 and 5.4 GHz Integrated systems operate at up to 43 Mbps Ethernet data rates, while the 4.9 GHz solution offers up to 35 Mbps Ethernet data rates. These systems are ideal for near- and non-line-ofsight environments.

Integrated Lite: The Lite versions of the PTP 400 Series Integrated bridges include all the same robust technology of the full-speed versions, but at less cost. Operating in the 5.8, 5.4 and 4.9 GHz frequencies, Lite solutions deliver Ethernet data rates up to 21 Mbps (5.8 and 5.4 GHz systems) or 17 Mbps (4.9 GHz systems). The Lite versions are software upgradeable to 43 Mbps (5.8 and 5.4 GHz models) or 35 Mbps (4.9 GHz models) as throughput requirements increase. PTP 400 Integrated Lite systems are excellent entry-level solutions for growing WISPs and ISPs and for any budget-constrained organisation that needs a robust solution to overcome interference and navigate obstructions.

Connectorised: PTP 400 Series Connectorised radios combine all the innovative technology found in the Integrated models with the high-gain advantage of external antennas. In extremely adverse environments, including deep non-line-of-sight, these solutions let you connect over greater distances, at a higher level of reliability and higher speed than comparable bridges. The 5.8 and 5.4 GHz Connectorised systems operate at up to 43 Mbps Ethernet data rates, while the 4.9 GHz systems deliver up to 35 Mbps throughput.

Connectorised Lite: The Lite versions of the PTP 400 Series Connectorised bridges offer all the performance and reliability of the full-speed versions, but at less cost. The 5.8 and 5.4 GHz Lite solutions deliver up to 21 Mbps Ethernet data rates, whereas the 4.9 GHz Lite systems operate at data rates up to 17 Mbps. These solutions are excellent choices for growing and budget constrained organisations that need to communicate in extremely challenging conditions. Then as bandwidth requirements grow, the 5.8 and 5.4 GHz systems are software upgradeable to 43 Mbps, while the 4.9 GHz systems can be upgraded to 35 Mbps.

Motorolas MOTOwi4 portfolio of innovative wireless broadband solutions create, complement and complete IP networks. Delivering IP coverage to virtually all spaces, the MOTOwi4 portfolio includes Fixed Broadband, WiMAX, Mesh, and Broadband-over-Powerline solutions for private and public networks.



How Far Will Connectorised Systems Take You?
Connectorised radios in the PTP 400 Series product line connect to external antennas to increase signal gain, and, therefore, the range and robustness of the link. As the diagrams show, throughput rates remain consistently high from a distance of a few miles to 200 km (124 miles). At the maximum range, 29.8 Mbps and 14.9 Mbps Ethernet data rates full-speed and Lite models respectively can
be sustained over a line-of-sight path, using a six-foot antenna. In non-line-of-sight environments, Connectorised systems can increase link availability up to 99.999%. Prior to purchase, you can use Motorolas PTP Link Estimator to predict link reliability and throughput for your specific wireless application. (A list of approved antennas that meet FCC requirements is provided on our web site.)

A Unique Technology Combination
The success of the PTP 400 Series bridges results from a unique combination of technologies the overall effect of which is much more powerful than using any of them individually. You can acquire this combination in a surprisingly small form factor that is easy to install and maintain, even in aesthetically or physically restrictive environments. These technologies include:

Multiple-Input Multiple-Output (MIMO): The radios radiate multiple beams from the antenna the effect of which is to significantly protect against fading and radically increase the probability that the receiver will decode a useable signal.

Intelligent Orthogonal Frequency Division Multiplexing (i-OFDM): OFDM is now the industryrecognised method of reducing interference caused by signals that take multiple paths arriving out of phase at the receiver. Motorola takes this technology further by using more sub-carriers and pilot tones than competitors to provide class-leading capability for handling multipath dispersion and instant fade recovery.

Advanced Spectrum Management with i-DFS: Our intelligent Dynamic Frequency Selection (i-DFS) is at the heart of our exceptional spectrum management capabilities. At power-up and all during operation, the bridges scan the band 500 times a second and automatically switch to the clearest channel. Our 25-hour, time-stamped database alerts you to any interference that does exist and provides statistics that help you pinpoint which channels provide the clearest data paths, offering virtually interference-free performance even in highly-congested environments.

Adaptive Modulation: Transmitter and receiver negotiate the highest mutually sustainable data rate then dynamically upshift and downshift the rate as conditions change, providing the maximum performance possible within the current power limits.

Spatial Diversity: Having the capabilities of Spatial Diversity, PTP 400 Series bridges can enable two distinct paths that are not simultaneously affected by fading or multipath, giving you a very reliable link in adverse conditions.

Best-In-Class Radio: A powerful transmitter combined with a super-sensitive receiver delivers a class-leading 168 dB system gain. This is as much as 25 times better than the performance of comparable point-to-point wireless solutions.
