Air Interface



Adaptive Modulation – PTP600 & PTP500


Adaptive modulation

The PTP 600 series can transport data over the wireless link using a number of different

modulation modes ranging from 256QAM 0.81 to BPSK 0.63. For a given channel

bandwidth and TDD frame structure, each modulation mode transports data at a fixed

rate.

Also, the receiver requires a given signal to noise ratio in order to successfully

demodulate a given modulation mode. Although the more complex modulations such as

256QAM 0.81 will transport data at a much higher rate than the less complex

modulation modes, the receiver requires a much higher signal to noise ratio.

The PTP 600 series provides an adaptive modulation scheme where the receiver

constantly monitors the quality of the received signal and notifies the far end of the link

of the optimum modulation mode with which to transmit. In this way, optimum capacity

is achieved at all times. This is one of a number of features which allows the PTP 600 to

operate in challenging non-line of sight radio channels.





Specifications of capacity for all channel bandwidths, modulation modes andconfigurations are provided in Data throughput capacity.

Specifications of receive level thresholds for each modulation mode (assuming no

interference) are provided in the various system threshold tables in the user guides

PTP LINKPlanner includes an estimate of mean data rate, the data rate provided by eachmodulation and the percentage of time spent in each modulation mode.





MIMO

PTP LINKPlanner includes an estimate of mean data rate, the data rate provided by each

modulation and the percentage of time spent in each modulation mode.

Multiple-Input Multiple-Output (MIMO) techniques provide protection against fading

and increase the probability that the receiver will decode a usable signal. When theeffects 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.

The PTP 600 & PTP500 transmits two signals on the same radio frequency, one of which

is vertically polarized and the other horizontally polarized. The PTP 600 & PTP500 also

has the ability to adapt between two modes of operation:





Dual Payload:

When the radio channel conditions allow, the PTP 600 & PTP 500 will transmit two

different and parallel data streams, one on the vertical channel and one on the

horizontal channel. This doubles the capacity of the PTP 600 & PTP 500.

Single Payload:

As the radio channel becomes more challenging, the PTP 600 & PTP 500 has the

ability to detect this and switch to a mode which transmits the same data stream on

both vertical and horizontal channels. This provides polar diversity and is another key

feature which allows the PTP 600 & PTP 500 to operate in challenging non- line of sight

radio channels.



DSO – PTP600 & PTP500


Intelligent dynamic frequency selection

The PTP 600 & PTP 500 series uses an interference mitigation technique known as

Intelligent Dynamic Frequency Selection (i-DFS) (not available in the 2.5 GHz band).

Both the Master and Slave continually monitor for interference on all channels and then

select the best frequency of operation. This is a dynamic process where the PTP 600 &PTP 500 can continually move channels in response to changes in interference.

Two modes of operation are available:

• First mode: the two link directions are forced to select the same frequency, determined

by the Master.

• Second mode: the frequency of operation can be determined independently for each

direction. This mode is not permitted in radar regions.



Synchronisation – PTP600 & PTP500


Synchronized networks

TDD synchronization can be used to relax constraints on the frequency planning of PTP

networks. Synchronization has the following benefits:

• Allows tighter frequency re-use, and thus wider channel bandwidth.

• Allows more convenient collocation of units on a single mast .

• Allows use of smaller or lower performance antennas.

• Reduces inference, resulting in use of more efficient modulation modes.

In a correctly designed synchronised network, all links are configured with the sameTDD frame duration, and the TDD frame contains guard periods longer than the

propagation delay between the most distant interfering units.





Each synchronized unit is assigned to one of two phases. A master ODU can be

assigned to either phase. A slave ODU must be assigned to a different phase from theassociated master ODU.

The phase is set by suitable configuration of TDD Frame Offset.

TDD synchronization eliminates RF interference between units in the same phase.

This means that frequency planning in a synchronized network is concerned only with

interference between units in different phases. Frequency planning is still necessary,

but the number of potential interference paths to be considered is halved.

Frequency planning in a synchronized TDD network has approximately the same level

of complexity as frequency planning in a Frequency Division Duplex (FDD) network.



h i i &





TDD synchronization

PTP 500 does not allow TDD synchronization to be enabled when telecoms

(E1 or T1) is enabled.

Additional hardware

To synchronize PTP 500 links, one PTP-SYNC unit is required for each masterODU. The PTP-SYNC unit is connected in line in the drop cable between the

PIDU and the ODU, and is collocated with the PIDU.

PTP 500 System Releases earlier than 500-04-00 do not support PTP-SYNC.

PTP 300 System Releases earlier than 300-05-01 do not support PTP-SYNC.

S h i i 600 & 00





Timing references for use with PTP-SYNC

PTP-SYNC requires an external timing reference in all but the simplestnetworks. Up to ten PTP-SYNCs can be connected in a chain to share the

timing signal from one timing reference. In the majority of applications, one

reference is required for each site that contains master ODUs.

The timing reference can be from any timing system that provides a 1 Hz

signal, accurately synchronized in frequency and phase with a network-wide

master timing reference. GPS timing receivers are a very practical way of

obtaining a suitable reference.

The PTP-SYNC is compatible with the following GPS timing receivers:

• Trimble Acutime™ Gold GPS receiver

In simple networks where all master ODUs are at a single site, the external

reference can be omitted. In this case, one ODU acts as a reference for other

collocated units.

S h i i PTP600 & PTP500





Configuring the TDD frame

In synchronized operation, frame duration and burst duration must be

configured directly in the web-based management interface. Frame duration

must be identical across all links in a synchronized network.

PTP LINKPlanner provides a capability for computing suitable frame

parameters in a synchronized network. Please refer to the PTP LINKPlanner

User Guide for guidance on configuring TDD synchronization.

Link symmetry is always 1:1 in synchronized networks.

Synchronisation – PTP-SYNC - Mounting


GPS receiver location requirements

The GPS receiver for PTP-SYNC must be mounted at a location that meets the

following requirements:

• It must be possible to protect the installation as described in General

protection requirements

• It must have an un-interrupted view of the sky.

• It must receive an adequate signal from at least four GPS satellites.

• It must be mounted at least 1 m (3 ft), preferably 2 m (6 ft), away from other

GPS receiving equipment.

• It must not be sited in the field of radiation of co-located radio

communications equipment and should be positioned at a distance of at least 3m (10 ft) away.

Mount the GPS receiver on the wall of the equipment building, if there is a

suitable location on the wall that can meet these requirements. Failing that,

mount it on a metal tower or mast.

Cambium modules use TDD (Time Division Duplexing) toalternate transmissions between uplink and downlink

• Cambium RMs use TDMA (Time Division Multiple Access) onthe uplink frames to resolve contention for accessing the AP

• If one AP were to transmit while another is receiving, thepossibility for interference or de-sensing exists.

• APs must be synchronized to prevent interference and de-

sensing.

Using GPS for Synchronization

•

The CMM3/4 and uGPS contains a GPS receiver that trackseight or more satellites and derives a precise clock that is usedto synchronize Cambium APs.

• This clock is used to synchronize the transmit/receive cycles ofevery module in your Cambium Wireless Broadband network.

• In addition to precise timing, the GPS receiver providesinformation on the latitude and longitude of the CMM,number of satellites being tracked, number of availablesatellites, and other information to aid in network diagnostics.
