PMP 450 Planning Guide Figure 1 Line Of Sight Diagram Whereas multi-pathing degrades a link in some technologies (FSK, for example), OFDM can often use multipathing to an advantage to overcome nLOS, especially in cases where the Fresnel zone is only partially blocked by buildings, “urban canyons”, or foliage. OFDM tends to help especially when obstacles are near the middle of the link, and less so when the obstacles are very near the SM or AP.

PMP 450 Planning Guide Radio tab of the AP Figure 8 Radio tab of the AP 1-20 pmp-0047 (March 2014)
PMP 450 Planning Guide The Radio tab of the AP contains some of the configurable parameters that define how the AP operates. Table 6 AP Radio attributes Attribute Meaning Radio Mode Reserved for future modes of operation. Frequency Band Select the desired operating frequency band. Frequency Carrier Specify the frequency for the module to transmit. The default for this parameter is None. For a list of channels in the band, see the drop-down list on the radio GUI.
PMP 450 Planning Guide Attribute Meaning Downlink Data Specify the percentage of the aggregate throughput for the downlink (frames transmitted from the AP to the subscriber). For example, if the aggregate (uplink and downlink total) throughput on the AP is 90 Mb, then 75% specified for this parameter allocates 67.5 Mb for the downlink and 22.5 Mb for the uplink. The default for this parameter is 75%.
PMP 450 Planning Guide Attribute Meaning Control Slots This field indicates the number of (reserved) control slots configured by the operator. The SM uses reserved control slots and unused data slots for bandwidth requests Uplink Data Slots are used first for data. If they are not needed for data in a given frame, the remaining data slots can be used by the SMs for bandwidth requests.
PMP 450 Planning Guide Attribute Meaning Transmitter Output Power This value represents the combined power of the AP’s two transmitters. Nations and regions may regulate transmitter output power. For example • 5.4/5.8-GHz modules are available as connectorized radios, which require the operator to adjust power to ensure regulatory compliance. The professional installer of the equipment has the responsibility to External Gain Receive Quality Debug • maintain awareness of applicable regulations.
PMP 450 Planning Guide Attribute Meaning Subscriber Color Code Rescan (When not on a Primary Color Code) This timer may be utilized to initiate SM rescans in order to register to an AP configured with the SM‘s primary color code. The time (in minutes) for a subscriber to rescan (if this AP is not configured with the SM‘s primary color code).
PMP 450 Planning Guide Subscriber Module (SM) The SM is a self-contained unit that houses both radio and networking electronics. The SM is available in a connectorized model and also in an integrated antenna configuration, but may also be used with a passive reflector dish or CLIP (Cassegrain Lens for Improved Performance, 5 GHz only). Figure 9 PMP 450 Series SM 3.5 GHz and 3.6 GHz PMP 450 SMs appear a bit different from the existing PMP 450 SMs.
PMP 450 Planning Guide Further reading on the SM For more information on the SM, refer to the following: • AP or SM site selection on page 1-65 describes how to select a site for the SM. SM interfaces Figure 10 SM interfaces SM Ground (connectorized models) Ethernet Sync/Default 3.5 GHz and 3.6 GHz SMs appear a bit different from the existing 450 SMs.

PMP 450 Planning Guide SM diagnostic LEDs The diagnostic LEDs report the following information about the status of the module. The SM LEDs provide different status based on the mode of the SM. An SM in “operating” mode will register and pass traffic normally. An SM in “aiming” mode will not register or pass traffic, but will display (via LED panel) the strength of received radio signals (based on radio channel selected via Tools, Alignment). The LED color helps you distinguish position of the LED.

PMP 450 Planning Guide Figure 14 Custom Frequency tab of the SM 1-32 pmp-0047 (March 2014)
PMP 450 Planning Guide In the radio tab of the SM, you may set the following parameters. Table 9 SM Radio attributes Attribute Meaning Custom Radio Frequency Scan Selection List Check any frequency that you want the SM to scan for AP transmissions. Prior to System Release 13.1, the PMP 450 SM boot sequence included loading the current channel bandwidth (10 MHz or 20 MHz, but not both) and frequency band configuration (3.6 GHz) and scanning selected frequencies in the respective frequency band.
PMP 450 Planning Guide Attribute Meaning Channel Bandwidth The channel size used by the radio for RF transmission. Selecting multiple channel bandwidths will increase registration and reregistration times. Cyclic Prefix Scan The cyclic prefix for which AP scanning is executed. AP Selection Method Operators may configure the method by which a scanning SM selects an AP. By default, AP Selection Method is set to “Optimize for Throughput”, which has been the mode of operation in releases prior to 12.0.
PMP 450 Planning Guide Attribute Meaning External Gain This value represents the amount of gain introduced by an external antenna. Receive Quality Debug Module Type Recommended Setting OFDM integrated antenna with LENS 5 OFDM Integrated antenna with CLIP 8 OFDM integrated antenna with reflector dish 15 To aid in link performance monitoring, the AP and SM now report the number of fragments received per modulation (i.e. QPSK, 16-QAM, 64-QAM) and per channel (polarization).
PMP 450 Planning Guide Cabling and lightning protection This section describes the cabling and lightning protection components of a PMP 450 installation. PMP and lightning protection Due to the full metallic connection to the tower or support structure through the AP antenna, grounding the AP and installing a 600SS surge suppressor at the Ethernet cable building ingress is strongly recommended. This suppresses overvoltages and overcurrents such as those caused by near-miss lightning.
PMP 450 Planning Guide Wireless operation This section describes how the PMP 450 wireless link is operated, including modulation modes, power control and security. Time division duplexing The system uses Time Division Duplexing (TDD) – one channel alternately transmits and receives rather than using one channel for transmitting and a second channel for receiving. To accomplish TDD, the AP must provide sync to its SMs.
PMP 450 Planning Guide Link operation – Dynamic Rate Adapt PMP 450 Series products offer five levels or speeds of operation – 1x (QPSK), 2x (QPSK-MIMO-B), 4x (16QAMMIMO-B), 6x (64QAM-MIMO-B), and 8x (256QAM-MIMO-B). If received power is less due to distance between the AP and the SM or due to obstructions, or if interference affects the RF environment, the system will automatically and dynamically adjust links to the best operation level.

PMP 450 Planning Guide Site planning This section describes factors to be taken into account when choosing sites for the AP or SM, power supplies, CMM4 (if applicable) and GPS antenna (if applicable). AP or SM site selection When selecting a site for the AP or SM, 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 3-14. • Height and location to achieve the best radio path.
PMP 450 Planning Guide Wind loading Ensure that the site will not be prone to excessive wind loading. Antennas and equipment mounted on towers or buildings will subject the mounting structure to significant lateral forces when there is appreciable wind. Antennas are normally specified by the amount of force (in pounds) for specific wind strengths. The magnitude of the force depends on both the wind strength and size of the antenna.
PMP 450 Planning Guide Calculation of lateral force (US) The magnitude of the lateral force can be estimated from: Force (in pounds) = 0.0042Av2 Where: Is: A surface area in square feet v wind speed in miles per hour The lateral force produced by a single PMP 450 unit at different wind speeds is shown in Table 28. Table 28 Lateral force - US Largest surface area (square feet) Lateral force (lb) at wind speed (miles per hour) 80 100 120 140 150 0.
PMP 450 Planning Guide Wind speed statistics Contact the national meteorological office for the country concerned to identify the likely wind speeds prevalent at the proposed location. Use this data to estimate the total wind loading on the support structures.

PMP 450 Planning Guide Link planning This section describes factors to be taken into account when planning links, such as range, obstacles, path loss and throughput. 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. This information is necessary in order to achieve an accurate link feasibility assessment.

PMP 450 Planning Guide 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).
PMP 450 Planning Guide Calculating Link Loss The link loss is the total attenuation of the wireless signal between two point-to-multipoint units. The link loss calculation is presented below: Link Loss (dB) = Transmit power of the remote wireless unit (dBm) − Tx Cable loss (dB) − Received power at the local unit (dBm) – Rx cable loss (dB) + Antenna gain at the remote unit (dBi) + Antenna gain at the local unit (dBi) Calculating Rx Signal Level The Rx sensitivity of each module is provided at http://www.
PMP 450 Planning Guide Calculating Fade Margin Free space path loss is a major determinant in Rx (received) signal level. Rx signal level, in turn, is a major factor in the system operating margin (fade margin), which is calculated as follows: system operating margin (fade margin) dB =Rx signal level dB − Rx sensitivity dB Thus, fade margin is the difference between strength of the received signal and the strength that the receiver requires for maintaining a reliable link.
PMP 450 Planning Guide Analyzing the spectrum To use the built-in spectrum analyzer functionality of the SM (or AP that is temporarily configured as an SM for spectrum analysis via the AP’s GUI) proceed as follows: Procedure 3 Analyzing the spectrum 1 Predetermine a power source and interface that will work for the SM in the area you want to analyze. 2 Take the SM, power source, and interface device to the area. 3 Access the Tools web page of the SM.
PMP 450 Planning Guide Anticipating Reflection of Radio Waves In the signal path, any object that is larger than the wavelength of the signal can reflect the signal. Such an object can even be the surface of the earth or of a river, bay, or lake. The wavelength of the signal is approximately • 2 inches for 2.4, 3.5GHz, 3.6 GHz, 5.4-GHz and 5.8-GHz signals. A reflected signal can arrive at the antenna of the receiver later than the non-reflected signal arrives.
PMP 450 Planning Guide Multiple OFDM Access Point Clusters When deploying multiple AP clusters in a dense area, consider aligning the clusters as shown below. However, this is only a recommendation. An installation may dictate a different pattern of channel assignments. Figure 18 Example layout of 16 Access Point sectors (ABCD), 90 degree sectors An example for assignment of frequency channels is provided in the following table.
PMP 450 Planning Guide Figure 19 Example layout of 16 Access Point sectors (ABC), 60 degree sectors An example for assignment of frequency channels and sector IDs is provided in the following table.

PMP 450 Planning Guide Planning for co-location and using the OFDM Frame Calculator Tool The first step to avoid interference in wireless systems is to set all APs to receive timing from a synchronization source (Cluster Management Module, or Universal Global Positioning System). This ensures that the modules are in sync and start transmitting at the same time each frame.
PMP 450 Planning Guide Figure 20 OFDM Frame Calculator tab In the Frame Calculator tab, you can set the following parameters. Table 52 OFDM Frame Calculator tab attributes 1-100 Attribute Meaning Link Mode For AP to SM frame calculations, select Multipoint Link Platform Type AP/BHM Use the drop-down list to select the hardware series (board type) of the AP. Platform Type SM/BHS Use the drop-down list to select the hardware series (board type) of the SM.
PMP 450 Planning Guide Attribute Meaning Downlink Data Initially set this parameter to the same value that the AP has for its Downlink Data parameter (percentage). Then, as you use the Frame Calculator tool in Procedure 4, you will vary the value in this parameter to find the proper value to write into the Downlink Data parameter of all APs in the cluster. PMP 450 Series APs offer a range of 15% to 85%, and default to 75%.
PMP 450 Planning Guide To use the Frame Calculator to ensure that all APs are configured to transmit and receive at the same time, follow the procedure below: Procedure 4 Using the Frame Calculator 1 Populate the OFDM Frame Calculator parameters with appropriate values as described above. 2 Click the Calculate button.
PMP 450 Planning Guide Visual line of sight does not guarantee radio line of sight. Surveying Sites Factors to survey at potential sites include • what pre-existing wireless equipment exists at the site. (Perform spectrum analysis.) • whether available mounting positions exist near the lowest elevation that satisfies line of site, coverage, and other link criteria.
PMP 450 Planning Guide Calculating the Aim Angles The proper angle of tilt can be calculated as a factor of both the difference in elevation and the distance that the link spans. Even in this case, a plumb line and a protractor can be helpful to ensure the proper tilt. This tilt is typically minimal.
PMP 450 Planning Guide Diagramming Network Layouts Avoiding Self Interference The following section includes information maximizing tower performance by minimizing self-interference. Physical Proximity Two AP clusters co-located on the same tower require a CMM. The CMM properly synchronizes the transmit start times of all modules to prevent interference and de-sensing of the modules. At closer distances without GPS synchronization, the frame structures cause self-interference.
PMP 450 Planning Guide Avoiding Other Interference Where signal strength cannot dominate noise levels, the network experiences • packet errors and retransmissions. • lower throughput (because bandwidth is consumed by retransmissions) and high latency (due to resends). Regular spectrum analysis is critical to RF planning.
PMP 450 Planning Guide Grounding and lightning protection This section describes the grounding and lightning protection requirements of a PMP 450 installation. Electro-magnetic discharge (lightning) damage is not covered under warranty. The recommendations in this guide, when followed correctly, give the user the best protection from the harmful effects of EMD. However 100% protection is neither implied nor possible.
PMP 450 Planning Guide Lightning protection zones The ‘rolling sphere method’ (Figure 22) is used to determine where it is safe to mount equipment. An imaginary sphere, typically 50 meters in radius, is rolled over the structure. Where the sphere rests against the ground and a strike termination device (such as a finial or ground bar), all the space under the sphere is considered to be in the zone of protection (Zone B).
PMP 450 Planning Guide General protection requirements To adequately protect a PMP 450 installation, both ground bonding and transient voltage surge suppression are required. Basic requirements The following basic protection requirements must be implemented: • The equipment must be in ‘Zone B’ (see Lightning protection zones on page 1-108). • The AP must be grounded to the supporting structure. • A surge suppression unit (600SS) must be installed close to the SM.
PMP 450 Planning Guide Protection requirements for a mast or tower installation If the AP or SM is to be mounted on a metal tower or mast, 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 tower or its lightning air terminal. • The metal tower or mast must be correctly grounded.
PMP 450 Planning Guide Protection requirements for a wall installation If the SM 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. Schematic examples of wall installations are shown in Figure 25.
PMP 450 Planning Guide Protection requirements on a high rise building If the AP is to be mounted on a high rise building, it is likely that cable entry is at roof level ( 1-112 pmp-0047 (March 2014)
PMP 450 Planning Guide Figure 26) and the equipment room is several floors below (Figure 27). The following additional requirements must be observed: • The AP must be below the lightning terminals and finials. • A grounding conductor must be installed around the roof perimeter, to form the main roof perimeter lightning protection ring. • Air terminals are typically installed along the length of the main roof perimeter lightning protection ring typically every 6.1m (20ft).
PMP 450 Planning Guide Figure 26 Grounding and lightning protection on building Error! No topic specified. Protection inside a high rise building The following protection requirements must be observed inside multi-story or high rise buildings (Figure 27): • 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.
PMP 450 Planning Guide Configuration options for TDD synchronization The PMP 450 system uses Time Division Duplexing (TDD) - one channel alternately transmits and receives - rather than using one channel for transmitting and a second channel for receiving. To accomplish TDD, the AP must provide sync to its SMs – it must keep them in sync.
PMP 450 Planning Guide GPS synchronization The Navigation Satellite Timing and Ranging (NAVSTAR) Global Positioning System (GPS) use 24 satellites to relay information for precise derivation of position and time. The cluster management module (CMM) contains a Cambium GPS Receiver. The CMM is a critical element in the operation of the system. At one AP cluster site or throughout an entire wireless system, the CMM provides a GPS timing pulse to each module, synchronizing the network transmission cycles.
PMP 450 Planning Guide Figure 28 One unsynchronized AP in cluster resulting in self-interference Time The result is self-interference. In this scenario, the self-interference can be avoided only by synchronizing the TDD transmit cycles of all APs that operate in the same frequency band. An AP that is isolated by at least 5 miles (8 km) from any other equipment can generate and pass sync pulse without GPS timing and not risk that interference will result from the generated sync.
PMP 450 Planning Guide Mounting the GPS receiver (CMM or UGPS) module on the equipment building If mounting the GPS receiver on the equipment building, select a position on the wall that meets the following requirements: • It must be below the roof height of the equipment building or below the height of any roof-mounted equipment (such as air conditioning plant). • It must be below the lightning air terminals. • It must not project more than 600mm (24 inches) from the wall of the building.
PMP 450 Planning Guide Data network planning This section describes factors to be considered when planning PMP 450 data networks. Understanding addresses A basic understanding of Internet Protocol (IP) address and subnet mask concepts is required for engineering your IP network. IP address The IP address is a 32-bit binary number that has four parts (octets). This set of four octets has two segments, depending on the class of IP address. The first segment identifies the network.
PMP 450 Planning Guide DNS Client The DNS Client is used to resolve names of management servers within the operator’s management domain (see Figure 30). This feature allows hostname configuration for NTP servers, Authorization Servers, DHCP relay servers, and SNMP trap servers. Operators may choose to either enter in the FQDN (Fully Qualified Domain Name) for the host name or to manually enter the IP addresses of the servers.
PMP 450 Planning Guide In the Cambium system, NAT supports many protocols, including HTTP, ICMP (Internet Control Message Protocols), and FTP (File Transfer Protocol). For virtual private network (VPN) implementation, L2TP over IPSec (Level 2 Tunneling Protocol over IP Security) and PPTP (Point to Point Tunneling Protocol) are supported. When NAT is enabled, a reduction in throughput is introduced at the SM (due to processing overhead).
PMP 450 Planning Guide For communications to outside the network segment, ARP reads the network gateway address of the router and translates it into the MAC address of the router. Then the communication is sent to MAC address (physical network interface card) of the router. For each router between the sending module and the destination, this sequence applies. The ARP correlation is stored until the ARP cache times out.
PMP 450 Planning Guide Translation bridging Optionally, you can configure the AP to change the source MAC address in every packet it receives from its SMs to the MAC address of the SM that bridged the packet, before forwarding the packet toward the public network. If you do, then • not more than 10 IP devices at any time are valid to send data to the AP from behind the SM.
PMP 450 Planning Guide Special case VLAN numbers This system handles special case VLAN numbers according to IEEE specifications: Table 54 Special case VLAN IDs VLAN Number Purpose Usage Constraint 0 These packets have 802.1p priority, but are otherwise handled as untagged. Should not be used as a management VLAN. 1 Although not noted as special case by IEEE specifications, these packets identify traffic that was untagged upon ingress into the SM and should remain untagged upon egress.
PMP 450 Planning Guide PMP modules provide the VLAN frame filters that are described in Table 55.
PMP 450 Planning Guide VLAN settings can also cause the module to convert received non-VLAN packets into VLAN packets. In this case, the 802.1p priority in packets leaving the module is set to the priority established by the DiffServ configuration. If you enable VLAN, immediately monitor traffic to ensure that the results are as desired. For example, highpriority traffic may block low-priority. Q-in-Q DVLAN (Double-VLAN) Tagging (802.1ad) PMP modules can be configured with 802.
PMP 450 Planning Guide Security planning This section describes how to plan for PMP 450 networks to operate in secure mode. Isolating APs from the Internet Ensure that the IP addresses of the APs in your network • are not routable over the Internet. • do not share the subnet of the IP address of your user. RFC 1918, Address Allocation for Private Subnets, reserves for private IP networks three blocks of IP addresses that are not routable over the Internet: • /8 subnets have one reserved network, 10.
PMP 450 Planning Guide • GUEST, who has no write permissions and only a limited view of General Status tab From the factory default state, configure passwords for both the root and admin account at the ADMINISTRATOR permission level, using the Account => Change Users Password tab. (If you configure only one of these, then the other will still require no password for access into it and thus remain a security risk.) If you are intent on configuring only one of them, delete the admin account.

PMP 450 Planning Guide Port Filtering with NAT Enabled Where NAT is enabled on the SM, you can filter only the three user-defined ports. The following are example situations in which you can configure port filtering where NAT is enabled. • To block a subscriber from using FTP, you can filter Ports 20 and 21 (the FTP ports) for both the TCP and UDP protocols. • To block a subscriber from access to SNMP, you can filter Ports 161 and 162 (the SNMP ports) for both the TCP and UDP protocols.

PMP 450 Planning Guide The ports that are filtered as a result of protocol selections in the Protocol Filtering tab of the SM are listed in Table 59.
PMP 450 Planning Guide • Block and Forward SM Packets to Backbone. This not only prevents multicast/broadcast and unicast SM-toSM communication but also sends the packets, which otherwise would have been handled SM to SM, through the Ethernet port of the AP. In the CMMmicro and the CMM4, SM isolation treatment is the result of how you choose to manage the port-based VLAN feature of the embedded switch, where you can switch all traffic from any AP to an uplink port that you specify.
PMP 450 Planning Guide Planning for airlink security Cambium fixed wireless broadband IP systems employ the following form of encryption for security of the wireless link: • DES (Data Encryption Standard): An over-the-air link encryption option that uses secret 56-bit keys and 8 parity bits. DES performs a series of bit permutations, substitutions, and recombination operations on blocks of data. DES encryption does not affect the performance or throughput of the system.
PMP 450 Planning Guide • SM Configuration: Configures authenticated SMs with MIR (Maximum Information Rate), CIR (Committed Information Rate), High Priority, and VLAN (Virtual LAN) parameters from the RADIUS server when an SM registers to an AP. • SM Accounting provides support for RADIUS accounting messages for usage-based billing.

PMP 450 Planning Guide Glossary After an AP with DFS is powered on it performs a channel availability check on its main carrier frequency for 1 minute, monitoring for the radar signature without transmitting. If no radar signature is detected during this minute, the module then proceeds to normal beacon transmit mode. If it does detect a radar signature, the frequency is marked for a 30 minute non-occupancy period, and the module moves to its 1st alternate carrier frequency.
PMP 450 Planning Guide Glossary Regulatory Note: A PMP 450 Series AP with a Country Code set to United States will not be configurable to another Country Code by installers or end users.

PMP 450 Planning Guide Glossary Term Definition Recharging Resumed accumulation of data in available data space (buckets). See Buckets. Reflection Change of direction and reduction of amplitude of a signal that encounters an object larger than the wavelength. Reflection may cause an additional copy of the wavelength to arrive after the original, unobstructed wavelength arrives. This causes partial cancellation of the signal and may render the link unacceptable.
