Introduction The Motorola wi4 Fixed Point-To-Point (PTP) 600 Series Wireless Ethernet Link, which consists of a pair of radios deployed one at each end of the link, operates on a single frequency channel in each direction using Time Division Duplex (TDD). In situations where a number of radios are installed on the same mast or where a large number of links are installed in a sizeable, dense network, it is possible that the performance or throughput of some of the links can be reduced.
System Overview To meet the high performance standards of a Motorola PTP broadband wireless network, Motorola has partnered with MemoryLink to deploy the MemoryLink UltraSync™ GPS-100M in a Motorola wi4 Fixed Point-to-Point (PTP) 600 Series network. With its integrated GPS receiver and internally-mounted antenna, the UltraSync GPS-100M generates a precise, highly stable, proprietary synchronization signal that is used by the PTP 600 Series radios to time and synchronize transmit and receive signals.
Product Features and Benefits UltraSync™ GPS-100M Features: • Integral GPS receiver – 12 channel • Passes 1000 Base-T protocol • Supports Ethernet cable lengths of up to 330 feet (100 meters) from the PTP 600 PIDU Plus to the UltraSync GPS-100M Eth1/PWR port • Robust enclosure weighing approximately 23 ounces (650 grams) • Small footprint – 5.92” (150 mm) height, 3.95” (100 mm) width and 2.
Installation Enabling TDD synchronization is a two-stage process: • Install the GPS Synchronization Unit (Motorola part number WB3001) • Enable TDD synchronization mode on the PTP 600 radio and configure related parameters using the PTP 600 Web GUI interface The following are deployment considerations for an UltraSync™ GPS-100M with a PTP 600 Series link: • Fixed-frequency operations only • Fixed TDD operation only – all synchronized links have the same ratio master to slave • Not presently available when
Installation continued The following diagram shows how to connect the UltraSync™ GPS-100M to the PTP 600 ODU fitted with a Lightning Protection Unit (PTP-LPU): UltraSync GPS-100M deployment diagram with a PTP 600 Series radio and a PTP Lightning Protection Unit The UltraSync GPS-100M sits between the Lightning Protection Unit and the ODU (outdoor unit) of a PTP 600 Series link. One UltraSync GPS-100M is required for each link.
