How To Build A Successful Radio Link




Most Network Managers know that microwave radio links lack a clear line of sight and access to spectrum, but to achieve a successful link that is going to deliver service 99. 999 % of the time the devil is in the detail.





In - house vs. Managed service





You may choose to do it yourself, with your own trusted team of experts, and subcontract each step to the most cost effective company, or you may choose to use a company that offers a complete turnkey service.





Spectrum





You can use unlicensed or light - licensed spectrum, but you risk the link blunder in the coming due to obstruction. For an disincentive free wireless service you need private spectrum. You can secure private licences from Ofcom for a few thousand pounds and subject to availability.





Alternatively if you are going down the managed service ramble your supplier will deal with this for you, or better sometime they will own their own licensed spectrum which makes the process of receiving it conspicuously quicker and it offers lower risk.





Even if you use light - licensed spectrum for rapid deployment at less cost, you would need an operator sanction to give you a high level of visibility when it comes to other planned uses of this spectrum.





Desktop Line of Sight





This can be carried out by looking at the lie of the land on a method to observe if it is theoretically possible to get a line of sight between your two points. Ideally you need a mechanical who uses colony imagery and technical desktop planning tools. They will look at building structures, any planning constraints and any planned builds, as well as look at the ease of access to the site for maintenance.





Choose the Correct Technology





The technology will depend on the functionality you depend upon, e. g.: the speed; resilience; availability; pleonasm; reporting and diagnostics; traffic management, etc. Choosing the correct technology is essential and there are a numeral of options out there. If you are sourcing it in - house you need to be acknowledging any limitations that the devices have that may not be evident from the technology vendor ' s specifications €“ variations on performance as a eventuality of the weather, for precedent.



If you outsource the build of your link it is also pertinent to check that your provider is technology agnostic. This is how you can protect they will not be prejudice in their choice and and so use the right equipment for the job.





Physical Line of Sight





If the desktop line of sight has been carried out to a high standard, this step in planning your microwave link should not throw up many surprises. There are however more factors that may affect the link ' s functionality and so a physical line of sight is still essential. A drive by or ground level survey may be useful, however a double ended line of sight survey from height is a likely requirement. You will need a team of engineers proved to work safely and legally at height. Ideally at this stage an MSV ( Multi Skilled Vacation ) should be carried out, by accessing the cabin ( zest having been ascertained at the desktop line of sight stage ) and grading the available structure space, power supply and recognition runs.













The Fresnel Region needs to be clear of any flora and fauna, and should any need to be balky you will depend upon a polished arborist or tree surgeon to do so. If you have a boost provider they will work with the useful body to overcome them €“ for case history scrutiny Council current meetings to begging permissions.





Village Asset





On case you will need to found a link fundamentally other than on one of your buildings €“ and you will lack planning permission to endow it. An expert in surveying is beneficial for the understanding of the gravy laws and in finding the most desired apartment for the link. Employment of glad eye is not the only genesis; the seat ' s knowledge needs to be assessed for relating power and stab requirements. Environmental concerns may also need to be addressed. Habitat rental costs will need to be particular when budgeting for your link €“ and these may not be included in the managed helping hand assessment. It helps to outsource to a affair who is used to dealing with these issues, as they will usually have preferential agreements in place with corner landlords.





Alpha





Once happy that the Fresnel Section is clear, the link needs to be installed. Avenue to the longitude needs to be agreed with the quarter owners. The installing engineers need to be fitted for the technology, structure access ( e. g. IRATA 1, Spainhoist Rope Genealogy, Rigging, RF awareness, First Aid and Recovery ) and official by the feeler celebration structure publician, if applicable. Testing and commissioning on the equipment needs to be carried out to guard the link is working in line with the design parameters €“ a where facilitated if the design and set down of a link is carried out by the same prom. Acceptance testing will need to conformed the criteria to accord with the apropos industry British Standards. Performance values also need to be in unanimity with those stated in the Ofcom accreditation.





You can either use separate suppliers for each element or use a company who offers a turnkey service for this.





Maintenance and Management





Your link will have to be monitored around the clock. If you don ' t have the ability to do so yourself your managed service provider should have the scale to deliver a Network Operations Centre ( NOC ) 24 / 7 that is fully backed up with reiteration built into the NOC systems and follows full Blow Recovery processes.





Having a managed radio network reduces downtime ( for quotation at MLL Telecom 90 % of faults are discovered and fixed without the need for the deployment of a network steer and typically before our customers mind an point ).





Summary





Whether you are self - managing your link, or out - sourcing to a service provider, you can normally engage in the balance of your CAPEX versus OPEX spend to what suits you €“ and with attention to detail with indepth planning a high quality link is attainable.
