Siklu Ordering Guide - How To Order a Complete Link

Siklu EtherHaul Series Ordering Guide

1. OverviewThe Siklu Etherhaul range consists of a series of Point to Point wireless

systems that operate in the 80GHz (E-Band) and 60GHz (V-Band)

frequency ranges. These high speed communication links provide

connectivity of up to 1Gbps full duplex. Each system consists of a set of

radios, antennas, mounting kit and licences, according to the individual link requirements.

This ordering guide is designed to assist Authorised Siklu Partners to ensure that each link has

been properly assessed and that the correct equipment is ordered from Purdicom. If you have

any questions regarding this guide or the Siklu range please contact Purdicom.

2. System DescriptionsIt is important to properly assess the customers current and future bandwidth requirements.

The Siklu Etherhaul range consists of a number of links that all differ slightly in terms of operating

frequency, data rate, range and enhanced feature sets. The Siklu 600T operates in the 60GHz

band, the 1200 series operate in the 80Ghz band.

60 or 80GHz?The main difference between a 60 and 80GHz systems is the maximum transmission range. The

60GHz spectrum suffers from high levels of attenuation due to oxygen absorption and this limits

the maximum transmission range to around 600-700m. However, 60Ghz systems are licence

free in the UK and so there is no spectrum rental cost. The Siklu Etherhaul 600T is considerably

smaller than the 1200 range at just 15cm square and as such is ideal for mounting on street

furniture or listed buildings. The 80GHz systems have 30 and 60cm antenna options and are

capable of providing links in excess of 4km.

TDD or FDD?Siklu Etherhaul systems are available as either TDD (Time Division Duplex) and FDD (Frequency

Division Duplex) TDD divides the data stream into frames and, within each frame, allocates a

specific time slot. This allows both the uplink and downlink to share the same frequency. The

Ether haul series offers the ability to define the percentage (90-10, 75-25, 10-90,25-75) so we

are no longer bound by 50/50 UL/DL. Using the FDD method, a distinct frequency channel is

assigned to both the transmitter and the receiver, in the case of the Siklu Etherhaul series this is

71/76GHz and 81-86GHz meaning that we are able to simultaneously up to 1GB in each

direction effectively doubling the pipe of a TDD link making it ideal for ultra-high capacity

requirements.

Single Pipe or Enhanced?Some Siklu Etherhaul systems are what is known as ‘Single Pipe’. This is a straightforward

Ethernet link with a single connection to the data network at each location. Enhanced systems

are capable of supporting Enhanced Layer 2 features such as Ethernet Ring Protection and

IEEE1588 Precision Timing Protocol.

3. Planning a LinkAny Millimetre Wave (MMW) system needs careful planning and installation. The systems need

absolute clear line of sight with clear Fresnel Zones to operate properly. The antennas have a

very narrow beamwidth and require a very secure mounting position. We recommend no less

than a 3” or 75mm mounting pole to ensure stability. Purdicom offer full training on survey and

installation techniques for the Siklu Etherhaul range.

There are a number of steps involved in the planning and ordering of a Siklu Etherhaul system:

1. To begin, we recommend that a site survey is carried out to assess the feasibility of a Siklu

Etherhaul system. Initially this will consist of a link budget calculation to establish whether the

desired data rate can be achieved. Purdicom will do this for you, or you can check using the online

Siklu Link Calculator (http://www.siklu.com/tools/EtherHaul_LBC/). Correct use of this tool is

essential, as it will predict the availability, data rate and expected RSSI of the link.

2. If the link budget is sufficient then a physical site survey is recommended. This will confirm the

line of sight between the two locations, the installation locations, cable runs and any other

requirements.

3. Procure the Ofcom licence if required.

Purdicom offer Enhanced LOS Planning used highly detailed planning software that includes full

UK ground clutter detail. This software is extremely accurate in predicting link availability and

can often save a considerable amount of time and money in survey costs by assessing a link in

detail before visiting a site. There is a small charge of £95 per link for this service. Contact us for

larger projects.



4. Ofcom - Complying wiith the RegulationsAll systems supplied by Purdicom are CE marked and comply with all

relevant UK and EU legislation. However, it is down to the installer to

ensure that these regulations continue to be met once the equipment is in

operation. This includes licensing the link if required and ensuring that the correct operating

parameters are configured.

The 60GHz V-Band is available licence free from Ofcom. This means that links can be deployed

so long as they comply with the Interface Requirements laid down by Ofcom as well as the

relevant European regulations. Purdicom can supply you with copies of the current require-

ments if required.

The 80Ghz E-Band is available in two options. In late 2013 Ofcom split the available spectrum

into two halves and each is controlled in different ways.

Self Coordinated – This half of the band is available for a price of £50 per link per year.

Ofcom holds a register of all self coordinated links and will offer limited mediation in the

unlikely event of interference. However, there is no guaranteed protection.

Coordinated – This half of the spectrum is fully coordinated by Ofcom and all users have

protection from interference. 500Mhz of spectrum, enough for 1Gbps, will cost £450

per year per link.



5. Ordering a LinkFollow the steps below to ensure you correctly order all the necessary parts that make up a Siklu

Etherhaul link

Each Siklu Etherhaul link consists of the following items:

o 2 x Outdoor Radio units

o 2 x Antenna

o 2 x Antenna Mounting Brackets

o 2 x Power Supplies

o Feature/Capacity License Keys as required

o Surge Protection as required

o Extended Warranty as required

Step 1

Select the correct model according to the table on page 2.

Some Siklu Etherhaul systems are supplied with a standard Integrated antenna that cannot be

removed. Some systems are available with an optional 60cm antenna for extended range.

TDD systems have set frequency radio that is the same at each end of the link so a single part

code covers both ends. FDD systems have one radio set to ‘High’ and one to ‘Low’ transmission

frequency. There are two part codes, one for each end of the link.

If the link budget calculation has determined that you require the 60cm antenna you need to

order the ODU with ADAPTER for the larger antenna.




5. Ordering a Link (cont.)

Step 2

Add antennas if required

Step 3

Add the correct mounting bracket

Step 5

Upgrade the link capacity if required. The Etherhaul 600T, 1200 and 1200F all come set to 100Mbps as

standard. They can be upgraded to 1Gbps as required. Two licence keys are required per link, one for each

radio.

The Etherhaul 1200TL and 1200FX come shipped as 700Mbps and 1Gbps respectively, there are no

capacity upgrade options for these systems.

Step 6

Optional accessories and feature licence keys are available if required. One licence key is required per

ODU.

All Siklu Etherhaul products have AES security upgrade as an option

We recommend the use of Ethernet Surge Protection to prevent electrical surge from damaging your

equipment. In addition, proper electrical earthing should be fitted to ODU assembly. At least one Surge

Protector should be use per end.

Step 7

Add extended warranty if required. Speak to your Purdicom Account Manager to discuss the various

packages that are available, including Advance Replacement.
