Page 19: Overview Of The Ptp 550 Series
Purpose Cambium PTP 550 products are designed for Ethernet bridging over point-to-point links in the unlicensed 5 GHz frequency band. Users must ensure that the PTP 550 Series complies with local operating regulations. The PTP 550 acts as a transparent bridge between two segments of the operator’s network. In this sense, it can be treated as a virtual wired connection between two points.

Page 24: Wireless Operation
Chapter 1: Product description Wireless operation Wireless operation This section describes how the PTP 550 wireless link is operated, including modulation modes, power control and security. Channel Bonding PTP 550 features three radio interfaces – two radios are used for data transfer and one radio is used for a real time spectrum analyzer and Dynamic Channel Selection (supported in a future release).
Page 25: Time Division Duplexing
Chapter 1: Product description Wireless operation Time division duplexing TDD cycle PTP 550 links operate using Time Division Duplexing (TDD). They use a TDD cycle in which the ODUs alternately transmit and receive TDD bursts. The TDD cycle is illustrated in Figure 2.
Page 26 Chapter 1: Product description Wireless operation Figure 2 TDD cycle – single channel Page 1-9...
Page 27: Link Scheduler
Chapter 1: Product description Wireless operation Link Scheduler The PTP 550 series provides three configuration options for apportioning the available capacity between the two link directions. • 75/25 – The capacity in the direction Master to Slave comprises 75% of available TDD frame, and the capacity in the direction of Slave to Master comprises 25% of available TDD frame.
Page 28: Adaptive Modulation
Chapter 1: Product description Wireless operation Adaptive modulation The PTP 550 can transport data over the wireless link using a number of different modulation modes ranging from 256-QAM to QPSK (selected independently between the two channels of operation). For a given channel bandwidth and TDD frame structure, each modulation mode transports data at a fixed rate.
Page 29: Encryption
Chapter 1: Product description Wireless operation Note The system automatically chooses between dual and single payload to try to increase the capacity of a link. Further reading For information about… Refer to… Single and dual payload modulation modes System threshold on page 3-36 Encryption...
Page 30: Ptp Networks
Chapter 1: Product description Wireless operation For sub-band 5.8 GHz, the maximum configurable transmit power of each radio is reduced by 6 dBm • If the configured channel on either radio spans two neighboring sub-bands, then the maximum configurable transmit power of each radio complies to the most conservative sub-band.
Page 31: Ethernet Bridging
Data network Transparent Ethernet service The PTP 550 Series provides an Ethernet service between one of the Ethernet ports at a local ODU and one of the Ethernet ports at an associated remote ODU. The service is transparent to untagged frames, standard VLAN frames, priority-tagged frames, provider bridged frames, and provider backbone bridged frames.
Page 32 Chapter 1: Product description Ethernet bridging Frames are transmitted at the Wireless port over a proprietary point-to-point circuit-mode link layer between ends of the PTP 550 link. Ethernet frames received at the Ethernet ports, or generated internally within the management agent, are encapsulated within a lightweight MAC layer for transmission over the wireless link.
Page 33: System Management
Chapter 1: Product description System management System management This section introduces the PTP 550 management system, including the web interface, installation, configuration, alerts and upgrades. Management agent PTP 550 equipment is managed through an embedded management agent. Management workstations, network management systems or PCs can be connected to this agent using an in- band network management mode.
Page 34: Network Management
Chapter 1: Product description System management Network management IPv4 and IPv6 interfaces The PTP 550 ODU contains an embedded management agent with IPv4 and IPv6 interfaces.

Page 64: Radio Spectrum Planning
Chapter 3: System planning Radio spectrum planning Radio spectrum planning This section describes how to plan PTP 550 links to conform to the regulatory restrictions that apply in the country of operation. Caution It is the responsibility of the user to ensure that the PTP product is operated in accordance with local regulatory limits.
Page 65: Regulatory Limits
(integrated) Regulatory limits Many countries impose EIRP limits (Allowed EIRP) on products operating in the bands used by the PTP 550 Series. For example, in the 5.4 GHz and 5.8 GHz bands, these limits are calculated as follows: • In the 5.4 GHz band (5470 MHz to 5725 MHz), the EIRP must not exceed the lesser of 30 dBm or (17 + 10 x Log Channel width in MHz) dBm.
Page 66: Channel Bandwidth
Chapter 3: System planning Radio spectrum planning The number and identity of channels barred by the license key and regulatory band is dependent on the channel bandwidth and channel raster selected. Channel bandwidth Select the required channel bandwidth for the link. The selection depends upon the regulatory band selected.
Page 67: Link Planning
The PTP 550 Series will operate at ranges from 100 m (330 ft) to 200 km (122 miles). Operation of the system will depend on obstacles in the path between the units. Operation at 40 km (25 miles) or above will require a near line-of-sight path.
Page 68: Adaptive Modulation
Chapter 3: System planning Link planning Seasonal Fading (dB) seasonal Equipment Capability (dB) capability Adaptive modulation Adaptive modulation ensures that the highest throughput that can be achieved instantaneously will be obtained, taking account of propagation and interference. When the link has been installed, web pages provide information about the link loss currently measured by the equipment, both instantaneously and averaged.
