Patent Description:
The object of the present invention is an advertising medium designed particularly for housing therein a <NUM> mobile cell antenna.

Data traffic demand through cellular networks by users of mobile phones and smartphones has grown exponentially and will continue to grow for several years. To efficiently address this exponential traffic demand new network technologies and topologies are required, since the current network infrastructures, based on large base stations (macrocells), cannot longer support the growing demand for connections expected in the upcoming years.

In this context, from the advent of the <NUM> technology a new type of low power access node is being installed, this node having a lower cost and dimensions, allowing for increasing the coverage and bandwidth of the known macrocell base stations. These low power nodes are known as <NUM> small cells, whose deployment should satisfy the growing demand requirements of the users.

The coverage range of <NUM> small cells is significantly smaller in comparison with the macrocells, ranging from several meters to several kilometres. Current <NUM> small cells have a reduced size and, to guarantee a correct coverage, must fulfil a number of specific installation requirements in connection to height, distance between each other, electrical power connection and optic fibre connection. For example, they must be installed at a height of at least three metres (<NUM>) and be separated from each other at least one hundred metres.

Therefore, network deployers such as mobile service companies, local governments, and official institutions, among others, must update the infrastructure network for providing a mobile signal in cities and places with high levels of mobile phone transit for meeting the growing demand user needs in city centres. However, the deployment of this technology is not yet being carried out in areas outside city centres due to the high investment costs required.

Furthermore, nowadays both administrations and companies in the field of telecommunications do not have any optimum installation plan, since the urban planning regulations require specific permissions threatening the viability and approval times.

None of the ways considered to date for deploying this network offers a viable and economic solution, since the ideal situation requiring over <NUM><NUM> mobile small cells would entail an exorbitant cost in civil works and installations, while at the same time the execution and installation times are unacceptable.

This situation is currently damaging sectors depending on the deployment of this network and technology for developing their products and services, such as the autonomous and connected vehicle sector; and the logistic sector, having similar use cases in the field of parcel transport.

Currently available data in connection with the road network in Spain show that there are <NUM> kilometres, <NUM> (Red de Carreteras del Estado, RCE) of which are managed by the Ministry of Industry and are used by <NUM>,<NUM>% of the total traffic and <NUM>,<NUM>% of the heavy traffic. Similarly, <NUM> are managed by the Autonomous Regions and carry <NUM>,<NUM>% of the traffic, and <NUM> are managed by the Diputaciones (the support the remaining <NUM>,<NUM>% of the traffic). Furthermore, city halls manage (according to the last official data of <NUM>) <NUM>, <NUM> of which are inter-city. Of the whole network, <NUM> are large capacity roads (toll motorways, freeways, and multi-lane roads), <NUM> of which belong to the RCE.

With such a number of kilometres of roads, in order to implement the autonomous and connected vehicle the best communication, computation and sensor technology is needed; this is only possible the is a <NUM> network available. The enormous number of complex operations lacking human intervention requires this type of technology. Exorbitant amounts of data must be transmitted from and to the vehicle. The real time information must be as detailed as possible in the surroundings of the vehicle and according to a certain distance depending on the itinerary: the car must anticipate the events around it for making the right decisions, and therefore it requires a complete communication infrastructure covering those needs.

The immediate future of these networks <NUM> comprises the evolution of the 14C-V2C communication standard, oriented to improve the security of the vehicle, encompassing V2V (Vehicle-to-vehicle), V2I (Vehicle-to-Infrastructure), V2P (Vehicle-to-pedestrian) y V2N (Vehicle-to-network). The object is to deploy what in the technical literature is known as Rel-<NUM><NUM><NUM> NR C-V2X or, translated to a more understandable language, a <NUM> radio interface for a "vehicle to everything" protocol based on mobile phone cells.

These <NUM> infrastructures will allow the advent of really autonomous vehicles having "perception" (thanks to high-capacity data transmission sensors), calculating routes in real time, updating the local conditions (by means of 3D maps) in real time or driving in coordination with the rest of vehicles around them.

The next phase in the mobility of the future are smart roads. Roads must move from the current inert function to an active function in connection with the mobility, efficiency, and connectivity with the users of the road, both vehicles and drivers.

In addition to this, the connected vehicle regulations to be implanted in Europe recently considered Wi-Fi technology as a standard. However, thanks to a suggestion made by the Transport European Commission, <NUM> of the <NUM> member states of the European Union voted for giving priority to <NUM>, rejecting Wi-Fi as the standard technology.

In this situation, Europe cannot fall behind the United States and China. These countries have begun a race for obtaining commercial control of the future <NUM> networks, which are essential for the autonomous vehicle technology where Europe is ahead.

Implanting this technology in our continent may be key for us to gain ground in comparison to our competitors but, in order for this to happen, the deployment of these infrastructures is required.

In parallel, traffic is increasing exponentially worldwide. Nowadays, around one thousand million (<NUM>) vehicles move along the roads globally and, by the year <NUM>, four thousand million (<NUM>) vehicles are estimated.

Connected autonomous vehicles are now a reality, and they have the potential to completely change the rules in the sector. But the roads are the critical and universal platform where these technologies must operate.

Unless innovation in road infrastructure evolves at the same time as automotive technology, traffic growth will continue to be a problem, and these technologies will unfold their real potential. The key to promote progress lies at the intersection between technological improvements and innovation in road infrastructures.

Road infrastructures are being redefined. In the past, the road infrastructure was limited to physical components such as barriers or traffic signs, but it now includes digital components such as wireless network technologies and artificial intelligence. The advent of connected autonomous vehicles is pushing the change, since they depend on telecommunication infrastructures to communicate with other vehicles and infrastructures.

Future intelligent infrastructures could offer numerous opportunities for improving the efficiency and security in roads, such as for reducing traffic accident incidence up to <NUM>%.

The ideal scenario in Europe is that all main land transport routes have uninterrupted <NUM> coverage by <NUM>. A huge challenge, no doubt.

Pilot test were carried out in controlled and limited areas due to the great cost of the deployment. Similarly, many of the elements in use today do not fulfil the minimum radiofrequency regulations and there is no standardized deployment regulation plan.

In short, there is currently a need in the field to develop new systems allowing for a fast and economic deployment of the <NUM> network.

Document <CIT> describes an advertising billboard with the ability to completely hide antennas for cellular telephones (big cells), or similar, in its interior, without producing shielding of the exit and entrance of the electromagnetic waves for the telephony service, thanks to the provision of a discreet amount of windows permeable to the waves, electromagnetic stripping of metallic materials the area of the windows.

The windows are covered with laminar patches of non-metallic material permeable to electromagnetic waves, preferably FGRP fiberglass reinforced plastic. In combination with the traditional metal profiles, there are included alternate profiles of non-metallic material permeable to electromagnetic waves, which fall within the area of said window or aperture on the cover of the grid, in order to allow the inner antennas to the billboard rendering the normal service without shielding the electromagnetic signals, but hidden inside the billboard.

Document <CIT> relates to a single-column advertising structure including a mobile telephone station (big cell), of the type that is provided with a platform for advertising posters or a telecommunications antenna at a height.

The single columns in formed by: a series of tubular bodies with a constant diameter; a ladder providing access through the inside of the column; a first platform which is wider than the diameter of the column; a telecommunications antenna on the upper part of the column; a second platform disposed at a higher level that the first platform; microwave links; and connection cables inside the tubular bodies.

The inventors of the present invention developed an advertising medium having the necessary means for the installation of a <NUM> small cell therein. The problem in connection with the placement of <NUM> small cells is therefore solved, since cities have a myriad of advertising mediums having several shapes and sizes which, being essentially empty, could house the <NUM> small cells. Furthermore, since the advertising medium of the present invention has means for installing the <NUM> small cell, such as for example cable input/output holes, particularly designed fixation plates, etc., the time needed for installing a <NUM> small cell is greatly reduced.

An additional advantage of the present invention is that the installation of advertising mediums does not require any permission from the corresponding institutions, or else complex civil works. The time needed for installation is therefore further reduced.

In addition, advertising mediums are visually non-aggressive elements that integrate fast in the urban field and, at the same time, they prevent a potential baseless psychosis in connection with a harmful radiation emission from the antennas.
