Important regulatory information

Complying with rules for the country of operation

The PTP 670 product operates in frequency bands between 4.8 GHz and 5.9 GHz. These bands are made available for licensed or unlicensed operation according to the individual rules and regulations in force in each country.

Ensure that the equipment is operated in accordance with applicable regulations. Obtain the necessary licenses or permits before using the equipment in licensed bands. Some regional variants of PTP 670 are locked to a single country of operation. For the

remaining regional variants, use the Cambium Networks Support Centre to obtain a countryspecific license key for the country of operation. Country-specific license keys are automatically populated with the list of regulatory bands allowed in that country.

In some regulatory bands, PTP 670 may be allowed as a secondary user of the band, where operation is subject to the condition that the product does not cause interference to primary users of the band. In this case, take care to avoid causing interference to primary users.

Radar avoidance

In countries where radar systems are the primary band users, the regulators have mandated special requirements to protect these systems from interference caused by unlicensed devices. Unlicensed devices must detect and avoid co-channel operation with radar systems.

The PTP 670 provides detect and avoid functionality for countries and frequency bands requiring protection for radar systems.

Installers and users must meet all local regulatory requirements for radar detection. To meet these requirements, users must install a license key for the correct country during commissioning of the PTP 670. If this is not done, installers and users may be liable to civil and criminal penalties.

Download the latest PTP 670 Series firmware and install it in the Outdoor Units (ODUs) before deploying the PTP 670 equipment. Instructions for installing firmware are provided in

Upgrading software image on page 7-79.

Specific expertise and training for professional installers

To ensure that the PTP 670 is installed and configured in compliance with the requirements of ISEDC and the FCC, installers must have the radio engineering skills and training described in this section. This is particularly important when installing and configuring a PTP 670 system for operation in the 5.1 GHz and 5.4 GHz UNII bands.

External antennas

When using a connectorized version of the product (as compared to the version with an integrated antenna), the conducted transmit power may need to be reduced to ensure the regulatory limit on transmitter EIRP is not exceeded. The installer must have an understanding of how to compute the effective antenna gain from the actual antenna gain and the feeder cable losses.

The range of permissible values for maximum antenna gain and feeder cable losses are included in this user guide together with a sample calculation. The product GUI automatically applies the correct conducted power limit to ensure that it is not possible for the installation to exceed the EIRP limit, when the appropriate values for antenna gain and feeder cable losses are entered into the GUI.

Antennas externes

Lorsque vous utilisez une version du produit sans antenne intégrée, il peut être nécessaire de réduire la puissance d'émission pour garantir que la limite réglementaire de puissance isotrope rayonnée équivalente (PIRE) n'est pas dépassée. L'installateur doit avoir une bonne compréhension de la façon de calculer le gain de l'antenne de gain de l'antenne réelle et les pertes dans les câbles de connections.

La plage de valeurs admissibles pour un gain maximal de l'antenne et des pertes de câbles de connections sont inclus dans ce guide d'utilisation avec un exemple de calcul. L'interface utilisateur du produit applique automatiquement la limite de puissance menée correct afin de s'assurer qu'il ne soit pas possible pour l'installation de dépasser la limite PIRE, lorsque les valeurs appropriées pour le gain d'antenne et les pertes de câbles d'alimentation sont entrées dans l’interface utilisateur.

Overview of the PTP 670 Series

This section introduces the key features, typical uses, product variants and components of the PTP 670 series.

Purpose

Cambium PTP 670 Series Bridge products are designed for Ethernet bridging over point-topoint (PTP) and high-capacity multipoint (HCMP) microwave links in licensed, unlicensed and lightly-licensed frequency bands between 4800 MHz and 6050 MHz. Users must ensure that the PTP 670 Series complies with local operating regulations.

The PTP 670 Series 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. The PTP 670 Series filters frames it does not need to forward. The system is transparent to higher-level protocols such as VLANs and Spanning Tree.

forwards 802.3 Ethernet frames destined for the other part of the network and

Key features

The PTP 670 is a high performance wireless bridge for Ethernet traffic with a maximum throughput of 450 Mbps. It is capable of operating in line-of-sight (LOS), near-LOS and nonLOS propagation condition. Its maximum LOS range is 250 km. The PTP 670 operates in licensed, unlicensed and lightly-licensed frequency bands between 4800 MHz and 6050 MHz. It has a very high spectral efficiency of 10 bps/Hz and supports a channel bandwidth of up to 45 MHz. The PTP 670 Integrated ODU has its own flat plate antenna with antenna gain 23 dBi. The PTP 670 Connectorized ODU is designed for use with an external antenna.

The wireless link uses Time Division Duplex (TDD) and supports both symmetric and asymmetric TDD configurations.

PTP 670 operates in two distinct wireless topologies: point-to-point (PTP) and high-capacity multipoint (HCMP). A PTP link consists of one outdoor unit (ODU) configured as a Master and one ODU configured as a Slave. An HCMP sector consists of one ODU configured as a Master and up to eight ODUs configured as Slaves.

From an Ethernet point-of-view, the PTP 670 wireless link is a transparent Layer 2 bridge. It supports up to three Gigabit Ethernet ports. Two ports support twisted pair Gigabit Ethernet. One of them is capable of providing power via standard 802.3at PoE to an external device such as a video surveillance camera or a wireless access point. The third port accepts either a twisted pair or fibre GE SFP module.

The PTP 670 Series supports an optional TDM adaptor that allows E1 or T1 telecoms circuits to be bridged over the wireless link.

The PTP 670 Series has extensive quality of service (QoS) classification capability and supports up to eight levels of queues. Management of the unit may be via the same interface as the bridged traffic (in-band management) or on a separate port (out-of-band local or remote management).

Typical bridge deployment

The PTP 670 is an “all outdoor” solution consisting of a wireless bridge between two sites. Each site installation consists of a PTP 670 Integrated or PTP 670 Connectorized outdoor unit (ODU), and a power injector (PSU) (Figure 1). The ODU provides the following interfaces:

• PSU port: This provides proprietary power over Ethernet and connection to the management and/or data networks via 100BASE-TX or 1000BASE-T Ethernet. In the basic configuration, this is the only Ethernet connection to the ODU.

• SFP port: This provides an optical or copper Gigabit Ethernet interface for customer data and/or network management.

• Aux port: This provides an optional power and 100BASE-TX or 1000BASE-T Ethernet connection to an IEEE803.2at device such as a video camera or wireless access point.
