Interference

Interference is the reception of signals from sources other than the intended source

When unit is receiving data from its peer, if at the same time it also receives signal from nearby RF source, data flow is interfered

Nearby RF sources do not interfere transmission of signal

One can distinguish two type of interferences

External interference or noise:

Interference is generated by an unknown or unqualified source

One way to cope is to identify the interfering frequency source (using spectrum analyzer) and to move away from it (using different frequency, narrow beam width antenna, tuning receiver sensitivity …)

Self interference:

Two or more devices in the same network interfere with each other

Proper RF planning can go a long way to mitigating self-interferences(ensuring nearby device do not use adjacent channel and keeping enough physical separation between units)

In addition Base Station synchronization is a powerful mitigation tool



With asynchronous protocol (such as WORP)

Each base station adapts its transmit/receive pattern to the data flow

When multiple base stations are collocated, each follows its own transmit/receive pattern resulting in possible self interference condition

The first step toward Base station synchronization is to make sure that synchronous protocol is used

With synchronous protocol (such as WORP Sync)

Each base station follows a predefined and constant transmit/receive pattern

When multiple base station are collocated, even if they all follow the same transmit/receive pattern, they may not be synchronized with each other resulting in possible self interference condition

The second step toward Base station synchronization is to make sure that all devices are synchronized together

Base Station Synchronization requires all nearby Base Station to use the same time reference to start the transmit/receive pattern simultaneously

It can be achieved by:

Master Base Station sending sync signal to collocated Base Stations

All Base Station following the same external clock reference (such as GPS)

The goal is to ensure that nearby devices all transmit or receive simultaneously

Synchronization is only needed for the Base Stations

Client follow Base Station pattern and thus are de facto synchronized

Only Base Station are collocated on one physical site

Proxim Solution

Proxim’s initial approach to interference, with Tsunami® 8100/8200 series, is a high quality radio device coupled with the tools necessary to enable proper radio planning

Good adjacent channel rejection

Base stations can be installed 3 meters from each other without self-interfering

Wide frequency range and agility

No need for different hardware variant to use the best available channels

Automatic Channel Selection and Dynamic Channel Selection select optimum channel at boot up time or during operation

WORP robustness

Forward Error Correction and an advanced retry mechanism ensures data transmission even in harsh RF environment

With the growing demand for capacity, network managers tend to increase the number of Base Stations per site.

It results in more complex planning to avoid self-interference issue

WORP Sync

WORP Sync is the synchronous variant of WORP®

It is designed to mitigate interference found in dense networks and simplify channel planning task

Based on a Time Division Multiplexing architecture it defines a fixed transmit/receive pattern to be used by all units across the wireless network

WORP Sync must be loaded on all devices that are part of the network.It is compatible with the following devices:

Tsunami® 8200-G and 820 Base Station and Quickbridge.

Requires one pulse per second external source

Tsunami 820 support to be released soon

Tsunami® 8100, 8200 and 820 clients (SU / CPE)

No specific hardware required

WORP Sync is also capable of matching other vendors transmit/receive pattern

First release includes Cambium mode allowing to co-exist with PMP 100, 430 and 450 network


WORP Sync Network Setups

WORP Sync allows the following setups:

Two Base Station, AA channel design

Elements of one sector should not receive signal from the other sector

Three Base Stations, ABC channel design

All three sectors should use unique frequency

Channels A, B and C can be adjacent

Four Base Stations, ABAB channel design

Back to Back sector can re-use the samefrequency as long as elements of one sector do not receive signal from the opposite sector

Channels A and B can be adjacent


WORP Sync Modes

WORP Sync proposes three synchronous modes

Proxim mode:Sets optimum performance for Proxim only network

2.5 ms time frame

20 to 80 % @ 20 MHz and 15 to 85 % @ 40 MHz DL ratio (5 % steps)

Maximum distance

Inter and Intra Frame delay

Cambium -PMP mode:Sets optimum performance to co-exist with Cambium PMP network

2.5 ms time frame

20 to 80 % @ 20 MHz and 15 to 85 % @ 40 MHz DL ratio (5 % steps)

Cambium control Slots and Maximum distance

Custom mode (via CLI only):Allows to manually configure WORP Sync for fine tuning

2.5, 5 or 10 ms time frame, configurable between both directions

Up to 3 sub slots per direction

Intra and Inter Frame delay


WORP Sync Modes

Two extra modes are also available

Autonomous mode

When the 1 Pulse Per Second signal is not received by the unit, it is possible to continue operation using unit internal timer as a reference

In this mode, the unit follow the defined receive/transmit pattern but it is not synchronized with nearby units.

“BSU operation (without GPS signal)” parameter should be set to Yes

WORP Sync Disabled mode (via CLI only)

In this mode, the unit uses Proxim’s proprietary polling protocol

Not yet interoperable with WORP


WORP Sync vs WORP

WORP Sync helps address self interference issues

It ensures that nearby radios receive or transmit simultaneously.

This is beneficial for a WISP with large network deployments.

WORP is robust to noise (unknown interference).

WORP flexibility allows it to postpone transmission and retries it at a better time.

WORP Sync Transmission occurs in the predefined time window even if unknown unit transmit at the same time.

WORP Sync is very efficient for predictable traffic.

If the traffic match the fixed uplink downlink ratio no time is wasted

This is beneficial for video surveillance deployment

WORP is very efficient for evolving network

WORP flexibility allows to match customer needs

WORP Sync follow a constant transmit/receive pattern, if customer traffic differs from the predefined UL/DL ratio, time slot is wasted

Wasted time

Rx


WORP Sync vs WORP

WORP Sync provides similar performance than WORP

With small channel size, WORP Sync overhead slightly impact throughput.

Deployment Recommendations

Physical Separation

1 meter vertical separation is required between units for optimal adjacent channel operation. (AB)

1 meter vertical separation and 2 meters horizontal separation is required for Co-channel operation. (ABAB).

Antenna orientation and alignment

Azimuth and tilting are very important calibrationswhen deploying for optimized configuration.

Ensure Subscriber only receive signal from its intended Base Station

Each environment is unique so co-location will require field experience to understand limitations


Deployment tool

Spectrum Analyzer and Advanced Spectrum Analyzer

Advance mode in Spectrum Analyzer is used to scan different channels and analyze the SNR values from different BSUs / SUs.

Configure each link in the cluster with different interference free channels that are 20 MHz apart or more.

Run the advanced spectrum analyzer on the SUs.

The SU should receive a strong signal only from its BSU, and the signals if received from any other BSUs/ SUs should be with very low SNR.
