The world we live in is constantly changing, and our society and its technological advances are the best examples of this.
Just as we are now seeing how we are gradually adopting a progressive change towards electric mobility, it originally took almost 50 years for the car and the tractor to displace horses from roads, farms and public transport.
It is common for us to resist incorporating new changes into our daily lives, either due to general scepticism, or because of the convenience of continuing with known methods, or both. But the reality is that time usually proves most innovations right, especially when they simplify our daily lives and highlight the well-known motto that sometimes “less is more”.
It is also time that usually benefits innovators and “early adopters” competitively, especially in terms of business, since they are the ones who find a competitive advantage over the slowness of their competitors.
A CHANGE FOR US
In our sector we are used to finding numerous technological innovations that mark a new path in the way of doing things and on this occasion we talk about why at Codipro we consider it worth seriously considering starting to carry out full-outdoor deployments.
KEY POINTS
To do this, we must first take into account the key points of a radio link deployment project; the investment in hardware, the installation costs, the maintenance of the system, the energy costs, the cost of renting the spaces to house the equipment, the maintenance and repair costs and the logistics management of the whole. It is clear that the ideal scenario is to be able to reduce the costs and time needed to carry out a deployment project, but... can full-outdoor deployment help us in this regard?
HOW ASSEMBLIES WERE MADE BEFORE VS. NOW.
In this image we can see how, from an initial type of assembly in which both the radio equipment and the IDU are located inside the installation, we moved to the split mounting system, known as split-mount. This new mounting system already had different advantages over the previous method.
Finally we can see the diagram of a full-outdoor assembly in which the outdoor equipment combines IDU+ODU in a single hardware that is also usually found in a compact size and with improved performance compared to other versions.
WHY DO (SOME OPERATORS) STILL BET ON SPLIT MOUNTING?
Among the advantages that split mounting usually presents and the reason why many operators still opt for it, are the easy access to the internal units, since we would not need to climb the antenna, the reuse of wiring in many cases and the fact that some operators own the buildings where this equipment is housed, so this does not incur additional costs and the fact that it is a type of installation already known to them.
WHY FULL-OUTDOOR GIVES YOU VALUE
Do you remember the list of key points of a radio link deployment project?
In addition to the improvement of these points; We find a lower investment in hardware, reduced installation time, easier system maintenance, reduced energy costs, reduced rental spaces and reduced number of visits for maintenance and/or repairs. A full-outdoor assembly offers us other added advantages such as greater simplicity in installation, a smaller number of components, thereby reducing the probability of incidents due to failure of the same, a smaller number of locations (which drastically reduces rental costs in the event that the operator is not the owner of the site), improved ease of maintenance (and which includes a reduction in the number of visits and trips for maintenance).
REDUCTION OF DERIVED ECONOMIC COSTS
If we look at the economic costs derived from a deployment and taking into account that the implementation costs are similar in the case of a split installation and a fully outdoor installation (they can even be reduced in the second case), clearly the main difference comes from the savings in renting indoor locations (for cases in which the operator is not the owner of these places).
If we estimate that the cost of renting an indoor location can be between €500 and €1000 per year, over a period of 10 years we can save an amount of €10,000 for each installation.
ENERGY SAVING
Energy costs are another of our clients' biggest concerns, and if we look at the manufacturer's data, we can see that the estimated savings for a full-outdoor installation compared to a split installation is 63W/hour.
It may not seem like a huge saving, but if we multiply it by the number of hours in a year, we find a saving of more than 550Kw per year per location.
In the case of an ISP with at least 100 locations, we would be talking about a saving of more than €8,200/year in energy costs alone.
HEALTHIER NETWORK
If we continue to look at the data provided by Ceragon, we can see that full-outdoor installations also clearly affect the MTBF value.
This indicator, which indicates the mean time between failures, is significantly lower in a full-outdoor installation, probably due to two main aspects: the first is that many IDU sites tend to be dusty places that suffer from many months of high temperatures during the year, and the second is the basic principle that the fewer units there are, the fewer breakdowns there are.
The result is a reduction in on-site repair visits of between 55 and 66%.
ADVANTAGES REGARDING SUSTAINABILITY
In the field of sustainability, we also find different advantages such as the reduction in electrical costs, due to the reduction in consumption of these units and not having to cool the IDU, and the already mentioned reduction in the number of logistics shipments (due to the lower number of units per deployment).
REDUCED ACQUISITION COSTS
Generally, a split-mount solution (RF + indoor unit) will cost more than a full-outdoor solution, and in the case of Ceragon, we can find a price reduction of between 25% and 60% in the acquisition costs of these devices.
In summary, at Codipro we see that full-outdoor implementation is clearly a highly recommended option for the expansion of your network.
You will have unique capabilities, improved sales time, greater simplicity in site acquisition and you will evolve favorably towards simpler networks by reducing the number of elements in it, which will facilitate improved management.
