PMP 450 Planning Guide Overview of PMP 450 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.
Overview of PMP 450 Product description System components PMP 450 Access Point Access Point Module (AP): A connectorized outdoor transceiver unit containing all the radio, networking, antenna, and surge suppression electronics. Access Point Power Supply: An indoor power supply module providing Power-over-Ethernet (PoE) supply to the Access Point. Cabling: Cat 5e cables, grounding cables, and connectors.
PMP 450 Planning Guide Access Point (AP) Access Point (AP) The AP is a self-contained unit that houses both radio and networking electronics. The AP is supplied in a connectorized configuration for use with an external antenna. Connectorized units with external antennas can cope with more difficult radio conditions.

Cabling and lightning protection Product description 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.
PMP 450 Planning Guide Wireless operation 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.
Wireless operation Product description Link operation – Dynamic Rate Adapt PMP 450 Series products offer four levels or speeds of operation – 1x (QPSK), 2x (QPSK-MIMO-B), 4x (16QAMMIMO-B), and 6X (64QAM-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 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 4-12.
Site planning Planning considerations Table 14 Sync cable length specification Configuration Maximum Cable Length (feet) Maximum Cable Length (meters) UGPS powered via external power source 330 100 UGPS powered via PMP 450 AP (via AP sync port) 130 40 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.
PMP 450 Planning Guide Site planning 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 16.

Link planning Planning considerations 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.

Link planning Planning considerations 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 Link planning Understanding Attenuation An RF signal in space is attenuated by atmospheric and other effects as a function of the distance from the initial transmission point. The further a reception point is placed from the transmission point, the weaker is the received RF signal. Calculating Link Loss The link loss is the total attenuation of the wireless signal between two point-to-multipoint units.
Analyzing the RF Environment Planning considerations 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 RF Environment 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.
Analyzing the RF Environment Planning considerations 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 5.4-GHz and 5.8-GHz signals. 5 inches for 2.4-GHz signals. A reflected signal can arrive at the antenna of the receiver later than the non-reflected signal arrives.
PMP 450 Planning Guide Analyzing the RF Environment 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 12 Example layout of 16 Access Point sectors (ABCD), 90 degree sectors An example for assignment of frequency channels is provided in the following table.
Analyzing the RF Environment Planning considerations Figure 13 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. See section Network migration planning on page 2-3 for more information on migrating to a PMP 450 network. Table 21 Example 5.8-GHz OFDM channel assignment by sector Symbol Frequency 2-24 A 5.740 GHz B 5.760 GHz C 5.
PMP 450 Planning Guide Analyzing the RF Environment 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.
Analyzing the RF Environment Planning considerations Figure 14 OFDM Frame Calculator tab In the Frame Calculator tab, you may set the following parameters. Table 22 OFDM Frame Calculator tab attributes 2-26 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 Analyzing the RF Environment 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%.
Selecting Sites for Network Elements Planning considerations 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 Selecting Sites for Network Elements 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.
Selecting Sites for Network Elements Planning considerations 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 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 desensing of the modules. At closer distances without GPS synchronization, the frame structures cause self-interference.
Diagramming Network Layouts Planning considerations 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 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.
Grounding and lightning protection Planning considerations Lightning protection zones The ‘rolling sphere method’ (Figure 16) 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 Grounding and lightning protection 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 2-34). The AP must be grounded to the supporting structure. A surge suppression unit (600SS) must be installed close to the SM.
Grounding and lightning protection Planning considerations Figure 17 Grounding cable minimum bend radius and angle Radius not less than 203 mm (8 in) Angle not less than 90° 2-36 pmp-0047 (June 2013)
PMP 450 Planning Guide Grounding and lightning protection 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.
Grounding and lightning protection Planning considerations 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 19.
PMP 450 Planning Guide Grounding and lightning protection 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 (Figure 20) and the equipment room is several floors below (Figure 21). The following additional requirements must be observed: The AP must be below the lightning terminals and finials.
Grounding and lightning protection Planning considerations Protection inside a high rise building The following protection requirements must be observed inside multi-story or high rise buildings (Figure 21): 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 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.
Configuration options for TDD synchronization Planning considerations Alternative to GPS synchronization A link can operate without GPS sync, but cannot operate without sync. The alternative to GPS sync is to configure the AP in the link to generate a sync pulse to pass to the SM. Depending on the RF environment in which the link operates, this latter alternative may or may not be plausible. For example, in Figure 22, AP4 is not synchronized with any of the other APs.
PMP 450 Planning Guide Configuration options for TDD synchronization Figure 23 GPS timing throughout the network Time 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).
Data network planning Planning considerations 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 Data network planning DNS Client The DNS Client is used to resolve names of management servers within the operator’s management domain (see Figure 24). 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.
Data network planning Planning considerations 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 Data network planning 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.
Data network planning Planning considerations 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 Data network planning Special case VLAN numbers This system handles special case VLAN numbers according to IEEE specifications: Table 24 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.
Data network planning Planning considerations Local SM Management: Disable in the SM, or All Local SM Management: Disable in the AP with an 802.1Q tag and a VID in the membership table Local SM Management leaving the bridge/ NAT switch through… Ethernet… any combination of VLAN parameter settings TCP/IP… with a VID not in the membership table any combination of VLAN parameter settings Egress with a VID not in the membership table Local Egress Priority on VLANs (802.
PMP 450 Planning Guide Data network planning The 802.1ad S-VLAN is the outer VLAN that is configurable on the Configuration => VLAN web page of the AP. The Q-in-Q EtherType parameter is configured with a default EtherType of 0x88a8 in addition to four alternate EtherTypes that can be configured to aid in interoperability with existing networks that use a different EtherType than the default. The C-VLAN is the inner VLAN tag, which is the same as 802.1Q.
Security planning Planning considerations 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.
PMP 450 Planning Guide Security planning 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.

PMP 450 Planning Guide Security planning 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.
Security planning Planning considerations Figure 26 Categorical protocol filtering BootP Server BootP Client IPv4 Multica st SNMP All Other IPv4 User Defined Port 1 SMB User Defined Port 2 User Defined Port 3 ARP PPPoE All Others The following are example situations in which you can configure protocol filtering where NAT is disabled: 2-58 If you block a subscriber from only PPoE and SNMP, then the subscriber retains access to all other protocols and all ports.
PMP 450 Planning Guide Security planning The ports that are filtered as a result of protocol selections in the Protocol Filtering tab of the SM are listed in Table 29.
Security planning Planning considerations Port Lockdown Cambium devices support access to various communication protocols and only the ports required for these protocols are available for access by external entities. Operators may change the port numbers for these protocols via the radio GUI or SNMP.
PMP 450 Planning Guide Security planning Filtering management through Ethernet You can configure the SM to disallow any device that is connected to its Ethernet port from accessing the IP address of the SM. If you set the Ethernet Access Control parameter to Enabled, then no attempt to access the SM management interface (by http, SNMP, ftp, or tftp) through Ethernet can succeed.
Security planning Planning considerations Planning for RF Telnet Access Control The RF Telnet Access feature restricts Telnet access to the AP from a device situated below a network SM (downstream from the AP). This is a security enhancement to restrict RF-interface sourced AP access specifically to the LAN1 IP address and LAN2 IP address (Radio Private Address, typically 192.168.101.[LUID]).
PMP 450 Planning Guide Security planning Framed IP allows operators to use a RADIUS server to assign management IP addressing to SM modules (framed IP address). Planning for SNMP security Canopy modules provide the following Configuration web page parameters in the SNMP tab. These govern SNMP access from the manager to the agent: Community String, which specifies the password for security between managers and the agent.
