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 omission in the next due to hardship. 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 airing your supplier will deal with this for you, or better presently they will own their own licensed spectrum which makes the process of receiving it very much quicker and it offers lower risk.
Even if you use light - licensed spectrum for rapid deployment at less cost, you would need an operator accreditation 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 composition to contemplate if it is theoretically possible to get a line of sight between your two points. Ideally you need a specialized who uses protectorate 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 depend upon, e. g.: the speed; resilience; availability; wordiness; reporting and diagnostics; traffic management, etc. Choosing the correct technology is essential and there are a quantity 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 issue of the weather, for citation.
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 secure they will not be distort in their choice and in consequence 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 fresh 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 resultant, however a double ended line of sight survey from height is a likely requirement. You will need a team of engineers fitted to work safely and legally at height. Ideally at this stage an MSV ( Multi Skilled Sojourn ) should be carried out, by accessing the cabin ( dash having been ascertained at the desktop line of sight stage ) and evaluating the available framework space, power supply and account runs.
The Fresnel Band needs to be clear of any flora and fauna, and should any need to be weak you will lack a efficient arborist or tree surgeon to do so. If you have a lift provider they will work with the proper body to overcome them €“ for model attending Council prevalent meetings to requisition permissions.
Longitude Acquisition
On case you will need to implant a link someday other than on one of your buildings €“ and you will lack planning permission to inaugurate it. An expert in surveying is beneficial for the understanding of the loot laws and in finding the most apt hamlet for the link. Work of peek is not the only leaven; the berth ' s reason needs to be assessed for same power and squeak requirements. Environmental concerns may also need to be addressed. Abode rental costs will need to be designful when budgeting for your link €“ and these may not be included in the managed cooperation charge. It helps to outsource to a enterprise who is used to dealing with these issues, as they will often have preferential agreements in place with zone landlords.
Origination
Once happy that the Fresnel Segment is clear, the link needs to be installed. Road to the home needs to be agreed with the room owners. The installing engineers need to be proved for the technology, structure access ( e. g. IRATA 1, Spainhoist Rope Lineage, Rigging, RF awareness, First Aid and Save ) and authorized by the questioning tailgating structure publician, if applicable. Testing and commissioning on the equipment needs to be carried out to secure the link is working in line with the design parameters €“ a bearings facilitated if the design and implant of a link is carried out by the same spree. Acceptance testing will need to good the criteria to accord with the congruous industry British Standards. Performance values also need to be in unanimity with those stated in the Ofcom warrant.
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 Trouble Recovery processes.
Having a managed radio network reduces downtime ( for representation at MLL Telecom 90 % of faults are discovered and fixed without the need for the deployment of a network govern and typically before our customers consideration an nut ).
Summary
Whether you are self - managing your link, or out - sourcing to a service provider, you can normally influence 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.
