Most Network Managers know that microwave radio links miss 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 ultimate due to handicap. For an monkey wrench 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 sally your supplier will deal with this for you, or better in consummation they will own their own licensed spectrum which makes the process of getting it exceptionally quicker and it offers lower risk.
Even if you use light - licensed spectrum for rapid deployment at less cost, you would need an operator authorization 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 depiction to beam if it is theoretically possible to get a line of sight between your two points. Ideally you need a specialized who uses dependency imagery and specialized 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 wish, e. g.: the speed; resilience; availability; pleonasm; reporting and diagnostics; traffic management, etc. Choosing the correct technology is essential and there are a number 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 denouement of the weather, for archetype.
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 provide they will not be prejudice in their choice and then 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 lob 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 potent, however a double ended line of sight survey from height is a likely requirement. You will need a team of engineers trained to work safely and legally at height. Ideally at this stage an MSV ( Multi Skilled Tarriance ) should be carried out, by accessing the cabin ( verve having been ascertained at the desktop line of sight stage ) and ranking the available framework space, power supply and broadcast runs.
The Fresnel Sector needs to be clear of any flora and fauna, and should any need to be disavowing you will depend upon a adept arborist or tree surgeon to do so. If you have a cooperation provider they will work with the fitting body to overcome them €“ for citation hinge Council conventional meetings to suit permissions.
Reservation Pride
On situation you will need to base a link climactically other than on one of your buildings €“ and you will hurting for planning permission to constitute it. An expert in surveying is beneficial for the understanding of the wad laws and in finding the most rightful compass for the link. Occupation of attending is not the only beginning; the seat ' s intuition needs to be assessed for like power and probability requirements. Environmental concerns may also need to be addressed. Void rental costs will need to be pointed when budgeting for your link €“ and these may not be included in the managed assistance monetary worth. It helps to outsource to a charge who is used to dealing with these issues, as they will repeatedly have preferential agreements in place with latitude landlords.
Installation
Once happy that the Fresnel Region is clear, the link needs to be installed. Access to the volume needs to be agreed with the city owners. The installing engineers need to be able for the technology, structure access ( e. g. IRATA 1, Spainhoist Rope Pedigree, Rigging, RF awareness, First Aid and Rescue ) and validated by the query do structure host, if applicable. Testing and commissioning on the equipment needs to be carried out to effect the link is working in line with the design parameters €“ a direction facilitated if the design and provide of a link is carried out by the same carousal. Acceptance testing will need to good the criteria to accord with the apt industry British Standards. Performance values also need to be in cooperation with those stated in the Ofcom authorization.
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 Mishap Recovery processes.
Having a managed radio network reduces downtime ( for copy at MLL Telecom 90 % of faults are discovered and fixed without the need for the deployment of a network handle and typically before our customers attention an matter ).
Summary
Whether you are self - managing your link, or out - sourcing to a service provider, you can normally officiate the balance of your CAPEX versus OPEX spend to what suits you €“ and with attention to detail with extensive planning a high quality link is attainable.
