Safety and Regulatory Safety and regulatory information ............................................................ . . . . This section describes important safety and regulatory guidelines that must be observed by personnel installing or operating PTP 250 equipment. Important safety information WARNING To prevent loss of life or physical injury, observe the safety guidelines in this section. Power lines Exercise extreme care when installing antennas near power lines.
Safety and Regulatory Using the correct power supply Always use the Motorola Power over Ethernet injector unit (PoE power supply) or Powered Indoor Unit (PIDU Plus) to power the ODU. Failure to use the correct power supply could result in equipment damage and will invalidate the safety certification and may cause a safety hazard.
Safety and Regulatory Drop cable tester The drop cable tester must NEVER be used at the ODU end connected to power from the PoE power supply. It must only be used at the bottom of the mast with a multimeter. This is because the PoE power supply voltage exceeds the limit allowed in some countries for safe handling in wet conditions and therefore may create a safety hazard. Primary disconnect device The main power supply is the primary disconnect device.
Safety and Regulatory Important regulatory information Operation of the PTP 250 product involves its use as an unlicensed device in frequency bands where it is not allowed to cause interference to licensed services (called primary users of the bands). Radar avoidance In some countries radar systems are the primary users and the regulators have devised special requirements to protect their operation from interference caused by unlicensed devices.

PTP 250 User Guide Wireless operation Wireless operation This section describes how PTP 250 wireless links are operated, including modulation modes, power control and security. Wireless Transmissions The PTP 250 uses Time Division Duplexing (TDD) transmission, which means that a single frequency channel is used for both Transmit and Receive. This is handled automatically by the radio. The PTP 250 transmits using Orthogonal Frequency Division Multiplexing (OFDM).
Wireless operation Chapter 1 Product description The system provides an adaptive modulation scheme where the receiver constantly monitors the quality of the received signal and notifies the far end of the link of the optimum modulation mode with which to transmit. In this way, optimum capacity is achieved at all times. NOTE PTP LINKPlanner includes an estimate of mean data rate, the data rate provided by each modulation and the percentage of time spent in each modulation mode.
PTP 250 User Guide Wireless operation Radar avoidance In regions where protection of radars is part of the local regulations, the PTP 250 must detect interference from radar-like systems and avoid co-channel operation with these systems. To meet this requirement, the PTP 250 implements the following features: ETSI regulations The regulations have radar detection requirements for both master and slave devices.
Wireless operation Chapter 1 Product description The requirements for a slave device are: • The slave device can only transmit after receiving a transmission from its associated master to demonstrate that the channel is an available channel. • The slave device is required to vacate the channel when the master device has detected a radar signal.
PTP 250 User Guide Wireless operation NOTE Equipment supplied to the USA can ONLY be set to operate with a Country Code which is fully compatible with FCC Rules. Using frequency planning Networks will benefit from the use of fixed channel allocations if (a) the network consists of multiple PTP links, and (b) RF interference predominantly arises from equipment in the same network.
Wireless operation Chapter 1 Product description Further reading on wireless operation For information on planning wireless operation, refer to the following: • Spectrum planning on page 2-2 describes the regulatory restrictions that affect radio spectrum usage, such as frequency range and radar avoidance. • Link planning on page 2-8 describes factors to be taken into account when planning links, such as range and path loss, and introduces PTP LINKPlanner.
PTP 250 User Guide Ethernet bridging Ethernet bridging This section describes how the PTP 250 controls Ethernet data in the customer and management networks. Customer network Transparent Ethernet service The PTP 250 provides an Ethernet service between the Ethernet port at a local ODU and the Ethernet port at an associated remote ODU.
Ethernet bridging Chapter 1 Product description Management network IP interface The PTP 250 ODU contains an embedded management agent with a single IP interface. Network management communication is exclusively based on IP and associated higher layer transport and application protocols. The factory default IP address of the management agent is 169.254.1.1. The products do not require use of supplementary serial interfaces. MAC address The MAC address is not configurable by the user.
PTP 250 User Guide Ethernet bridging Protocol model Ethernet bridging behavior at each end of the wireless link is equivalent to a two-port, managed, transparent MAC bridge where the two ports are: • Ethernet Port • Wireless Port Frames are transmitted at the Wireless port over a proprietary point-to-point circuitmode link layer between ends of the link.
Ethernet bridging Chapter 1 Product description Figure 1-11 Protocol layers between external interfaces and the management agent Further reading on Ethernet bridging For more information on Ethernet bridging, refer to the following: • Data network planning on page 2-21 describes factors to be considered when planning PTP 250 data networks. • Data network specifications on page 4-21 contains specifications of the PTP 250 Ethernet interface.
PTP 250 User Guide System management System management This section introduces the PTP 250 management system, including the web interface, installation, configuration, alerts and upgrades. Web server The PTP 250 management agent contains a web server. Web-based management offers a convenient way to manage the equipment from a locally connected computer or from a workstation connected through a management network, without requiring any special management software.
System management Chapter 1 Product description Firmware upgrade The management agent supports application firmware upgrade using the web-based interface. PTP 250 firmware images are digitally signed, and the ODU will accept only images that contain a valid Motorola PTP digital signature. The ODU always requires a reboot to complete a firmware upgrade. Obtain the application firmware and this user guide from the support website (http://www.motorola.com/ptp/support) BEFORE warranty expires.
Chapter 2 Chapter 2 Planning considerations ............................................................ . . . . This chapter provides information to help the user to plan a PTP 250 link. The following topics are described in this chapter: • Spectrum planning on page 2-2 describes the regulatory restrictions that affect radio spectrum usage, such as frequency range and radar avoidance. • Site planning on page 2-4 describes factors to be considered when choosing sites for the ODU and PoE power supply.
Spectrum planning Chapter 2 Planning considerations Spectrum planning This section describes the regulatory restrictions that affect radio spectrum usage. Each frequency variant has specific regulatory restrictions that affect frequency range, radar avoidance and channel width usage. Available spectrum Ensure the link is configured to conform to local regulatory requirements. The available spectrum for operation depends on the country of operation: • The 5.4 GHz band is available in all EU countries.
PTP 250 User Guide Spectrum planning Frequency selection The PTP 250 fully conforms to regional regulatory requirements for radar avoidance. In regions that mandate DFS, the unit first ensures that there is no radar activity on a given channel for a period of 60 seconds before radiating on that channel. Once a channel has been selected for operation, the unit will continually monitor for radar activity on the operating channel.
Site planning Chapter 2 Planning considerations Site planning This section describes factors to be taken into account when choosing sites for the ODU and PoE power supply. ODU site selection When selecting a site for the ODU, consider the following factors: • Height and location to ensure that people are kept away from the antenna; see Calculated distances and power compliance margins on page 4-25. • Height and location to achieve the best radio path.
PTP 250 User Guide Site planning Maximum cable lengths The maximum permitted lengths of interface cables in PTP 250 installations are specified in Table 2-1. Table 2-1 Maximum cable lengths Interface type Interface Maximum length Ethernet power and data ODU to network terminating equipment. 100 m (330 ft) Wind loading Ensure that the supporting structure will not be prone to excessive wind loading.
Site planning Chapter 2 Planning considerations The lateral force produced by a single PTP 250 ODU (integrated or connectorized model) at different wind speeds is shown in Table 2-2. Table 2-2 Lateral force – metric Type of ODU Largest surface area (square meters) Lateral force (Kg) at wind speed (meters per second) 30 40 50 60 70 Integrated 0.130 12 22 34 49 66 Connectorized 0.
PTP 250 User Guide Site planning Capabilities of the PTP 250 The structure and mounting brackets of the ODU are capable of withstanding wind speeds up to 242 kph (151 mph). Ensure that the structure to which the ODU is fixed is also capable of withstanding the prevalent wind speeds and loads. Wind speed statistics Contact the national meteorological office for the country concerned to identify the likely wind speeds prevalent at the proposed location.
Link planning Chapter 2 Planning considerations Link planning This section describes factors to be taken into account when planning links, such as range, obstacles and path loss. PTP LINKPlanner is recommended. Range and obstacles Calculate the range of the link and identify any obstacles that may affect radio performance. Perform a survey to identify all the obstructions (such as trees or buildings) in the path and to assess the risk of interference.
PTP 250 User Guide Link planning Path loss considerations Path loss is the amount of attenuation the radio signal undergoes between the two ends of the link. Calculating path loss The path loss is the sum of the attenuation of the path if there were no obstacles in the way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss) and a margin to allow for possible fading of the radio signal (Fade Margin).
Link planning Chapter 2 Planning considerations When to install connectorized units The majority of radio links can be successfully deployed with the integrated PTP 250. However the integrated units may not be sufficient in some areas, for example: • Where the path is heavily obscured by dense woodland on an NLOS link. • Where long LOS links (>23 km or >14 miles) are required. • Where there are known to be high levels of interference.
PTP 250 User Guide Grounding and lightning protection Grounding and lightning protection Structures, equipment and people must be protected against power surges (typically caused by lightning) by conducting the surge current to ground via a separate preferential solid path. The actual degree of protection required depends on local conditions and applicable local regulations. Motorola recommends that PTP 250 installation is contracted to a professional installer.
Grounding and lightning protection Chapter 2 Planning considerations Figure 2-1 Rolling sphere method to determine the lightning protection zones Assess locations on masts, towers and buildings to determine if the location is in Zone A or Zone B: • Zone A: In this zone a direct lightning strike is possible. Do not mount equipment in this zone. • Zone B: In this zone, direct EMD (lightning) effects are still possible, but mounting in this zone significantly reduces the possibility of a direct strike.
PTP 250 User Guide Grounding and lightning protection Basic requirements The following basic protection requirements must be implemented: • The ODU must be in ‘Zone B’ (see Lightning protection zones on page 2-11). • A lightning protection unit (LPU) must be installed within 600 mm (24 in) of the point at which the drop cable enters the building or equipment room.
Grounding and lightning protection Chapter 2 Planning considerations Figure 2-2 Grounding cable minimum bend radius and angle Radius not less than 203 mm (8 in) Angle not less than 90° ODU requirements The following ODU protection requirements must be implemented: • The ODU must be grounded to the supporting structure.
PTP 250 User Guide • Grounding and lightning protection In high lightning prone geographical areas, additional ground kits should be installed at spacing between 15 to 22 m (50 to 75 ft). This is especially important on towers taller than 45 m (150 ft). A schematic example of a mast or tower installation is shown in Figure 2-3.
Grounding and lightning protection Chapter 2 Planning considerations Protection requirements for a wall installation If the ODU is to be mounted on the wall of a building, then in addition to the general protection requirements (above), the following requirements must be observed: • The equipment must be lower than the top of the building or its lightning air terminal. • The building must be correctly grounded. A schematic example of a wall installation is shown in Figure 2-4.
PTP 250 User Guide Grounding and lightning protection Protection requirements on a high rise building If the ODU is to be mounted on a high rise building, it is likely that cable entry is at roof level (Figure 2-5) and the equipment room is several floors below (Figure 2-6). In addition to the general protection requirements (above), the following requirements must be observed: • The ODU must be below the lightning terminals and finials.
Grounding and lightning protection Chapter 2 Planning considerations Protection inside a high rise building The following protection requirements must be observed inside multi-story or high rise buildings (Figure 2-6): • The drop cable shield must be bonded to the building grounding system at the entry point to the building. • The drop cable shield must be bonded to the building grounding system at the entry point to the equipment area.
PTP 250 User Guide Grounding and lightning protection Connecting to the grounding conductor Figure 2-7 and Figure 2-8 illustrate the techniques employed to provide equipment grounding in high rise buildings. A steel component of the building can be used as a grounding conductor, provided it is part of the structural building steel and is effectively grounded.
