Overview of PMP 450 Product description Overview of PMP 450 This section introduces the key features, typical uses, product variants and components of the PMP 450. Purpose Cambium PMP 450 Series networks are designed for wireless point-to-multipoint links in the unlicensed 5.8 GHz and 5.4 GHz bands. Users must ensure that the PMP 450 Series complies with local operating regulations. The PMP 450 Series adds dramatically increased network throughput and capacity.
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.
Access Point (AP) Product description AP interfaces The AP interfaces are illustrated in Figure 4.

PMP 450 Planning Guide Subscriber Module (SM) 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).
Subscriber Module (SM) Product description Status information provided LED Color when active SYN/1 yellow PWR red SM in “Operating” SM in “Aiming” Mode Notes Mode Medium Receive Signal Power Blinking from slow to full-on to indicate medium power, getting stronger. Registration Indicator Off when registered to AP. On when not registered to AP. Mounting brackets For mounting PMP 450 SMs, Cambium Networks offers the SMMB1A mounting bracket.
PMP 450 Planning Guide Cabling and lightning protection 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.
Wireless operation Product description 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 Wireless operation 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.

Aggregate Throughput with 1/16 Cyclic Prefix to 1 SM (75%/25% DL/UL Ratio) – RF Link Test 5.4/5.8-GHz Nominal Combined Receive Sensitivity (including FEC) * Link Budget (dB) Margin to Registration Sensitivity (dB) 10 MHz Channel: 13 Mbps 26 Mbps 39 Mbps 20 MHz Channel -80 dBm -73 dBm -66 dBm 10 MHz Channel -83 dBm -76 dBm -69 dBm 20 MHz Channel 128.5 120.5 112.5 10 MHz Channel 131.5 123.
PMP 450 Planning Guide Wireless operation MIMO Multiple-Input Multiple-Output (MIMO) techniques provide protection against fading and increase the probability that the receiver will decode a usable signal. When the effects of MIMO are combined with those of OFDM techniques and a high link budget, there is a high probability of a robust connection over a non-line-of-sight path.
System management Product description System management This section introduces the PMP 450 management system, including the web interface, installation, configuration, alerts and upgrades, and management software. Management agent PMP 450 equipment is managed through an embedded management agent. Management workstations, network management systems or PCs can be connected to this agent using the module’s Ethernet port or over-the air (SM).

PMP 450 Planning Guide Network migration planning Network migration planning The PMP 450 Series offers current network operators the ability to migrate to PMP 450 for expanded network capacity and capability. The following sections are provided to aid in establishing a planning framework for deploying a PMP 450 system. Example PMP 450 deployment scenario The following sections detail example network deployment scenarios for the PMP 450 product.
Network migration planning 2-4 Planning considerations Term Definition Existing Ch BW (MHz) The channel size, or channel bandwidth used in the current system. For FSK (PMP 1x0 series) deployments, the channel bandwidth is always 20 MHz. For OFDM (PMP 430) deployments, the channel size may be 5, 10, or 20 MHz. Existing Total Bandwidth Used (MHz) The total amount of spectrum, in MHz, which is used by the existing system.
PMP 450 Planning Guide Network migration planning Sector capacity The following table exhibits the maximum aggregate sector throughput for several Cambium network deployments. This table may be used as a reference for planning new networks or for planning network upgrades.
Network migration planning Planning considerations Deployment scenario 1 – Replacing PMP 100 Equipment (20 MHz Channel Bandwidth) Deployment scenario 1 assumes that the existing network is comprised of PMP 1x0 equipment (i.e. PMP 100, PMP 120, etc.) with the configuration listed below in Table 9. The migration in this scenario results in a complete replacement of PMP 1x0 series equipment with PMP 450 equipment.

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 4-11.
Site planning Planning considerations Force (in kilogrammes) = 0.1045aV2 Where: Is: a surface area in square meters V wind speed in meters per second The lateral force produced by a single PMP 450 at different wind speeds is shown in Table 13 Lateral force metric and Table 14 Lateral force - US. Table 13 Lateral force - metric Largest surface area (square meters) Lateral force (Kg) at wind speed (meters per second) 30 40 50 60 70 .066 (AP) 6 11 17 25 34 .0027 (SM) 0.25 0.45 0.7 1 1.
PMP 450 Planning Guide Site planning Capabilities of the PMP 450 Series The structure and mounting brackets of the AP are capable of withstanding wind speeds up to 190 kph (118 mph). Ensure that the structure to which the AP is fixed to is also capable of withstanding the prevalent wind speeds and loads. The structure and mounting brackets of the SM are capable of withstanding wind speeds up to 190 kph (118 mph).
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.

PMP 450 Planning Guide Link planning Allowed EIRP (dBm) the EIRP limit allowed by the regulations, Antenna Gain (dBi) the gain of the chosen antenna, Cable Loss (dB) the loss of the RF cable connecting the AP to the antenna. For more information on EIRP limits, see Compliance with radio regulations on page 4-13. . 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.
Analyzing the RF Environment Planning considerations Rx signal level dB = Tx power − Tx cable loss + Tx antenna gain − free space path loss + Rx antenna gain − Rx cable loss This Rx signal level calculation presumes that a clear line of sight is established between the transmitter and receiver and that no objects encroach in the Fresnel zone. Calculating Fade Margin Free space path loss is a major determinant in Rx (received) signal level.
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. 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 18 Example 5.8-GHz OFDM channel assignment by sector Symbol Frequency 2-22 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 19 OFDM Frame Calculator tab attributes 2-24 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 An AP cluster on the same tower requires 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 sync from a CMM, 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 2-32). • 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° 2-34 pmp-0047 (December 2012)
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 AP or 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. DHCP DHCP enables a device to be assigned a new IP address and TCP/IP parameters, including a default gateway, whenever the device reboots.
PMP 450 Planning Guide Data network planning Allocating subnets The subnet mask is a 32-bit binary number that filters the IP address.

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 26.
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]).
