58   June/July 2018 unmanned systems inside BRUSSELS VIEW by PETER GUTIERREZ ing about slicing up the network, not splitting the spectrum." Geiss said recent high-level meetings re- vealed there are still big differences of opinion among stakeholders as to how to proceed. The Commission and other important players are looking closely at the 5.9 GHz band for 5G: "We know for example, that car manufacturers like VW are going ahead with this. We have a lot of support through the C-Roads project," an infra- structure investment initiative involving 16 EU member states. There is also a lot going on in the area of LTE- V2X (LTE mobile signals for vehicle-to-every- thing connectivity), he said, also using the 5.9 GHz band. "For example, BMW is very much supportive of 5.9 GHz and we have heard about where they see this going and the need to actu- ally integrate this into 5G technology. And then we have yet another approach from companies like Tesla who say we don't need any of these technologies, we'll just use sensors, visual iden- tity, together with artificial intelligence." The Radio Spectrum Committee, which Geiss chairs, is pushing for measures that will allow coexistence of LTE-V2X and urban rail ITS with existing ETSI ITSG525, all within the 5,875-5,925 MHz frequency band. "The principle of equal access to shared spec- trum shall be applied," he said, "taking into account the need to avoid harmful interfer- ence and the need for reliable safety-related operation in the whole band. We support the discussion of all options, including co-channel co-existence. Whatever we do, we need to en- sure uncompromised safety, and a technology- neutral approach." CAN'T WE ALL CO-EXIST? Lending his weight to the argument for co-exis- tence was Robert MacDougall, head of enterprise public policy at Vodafone who also represented the view of the automotive association 5GAA. He started by spelling out the concept of Cellular V2X: "C-V2X is a unified platform—and the word 'unified' is really important—integrating two things. First you have short-range direct com- munications between cars, so it's V2V (vehicle- to-vehicle), LTE-V2X PC5. Here you don't need a SIM card or network assistance, and you have low-latency, direct safety, communication that will work without network coverage. "And then you have the long-range element, and this is a different interface, and that track is carried over your licensed carrier network and can be particularly important for your infra- structure applications, V2N (vehicle-to-network) applications and V2Pedestrian applications." With C-V2X you get the best of both worlds, MacDougall argued. "You get the PC5 with short range V2V applications and you get the Uu (radio) interface for wide area and a broad- er range of services." As of now, 5GAA is test- ing C-V2X technology all over Europe and the world, he said, including in Germany, Spain, France, the UK, in the U.S., China and Korea. "This is a real international activity," he said. C-V2X has been developed by 3GPP, which is es- sentially the standardization forum for the cel- lular industry. We all know how successful the GSM has been on the global scale, so it's that same body that has developed this specification, expressly for connected and automated cars." In terms of recommendations for EU Policy for cooperative ITS, 5GAA believes any legis- lation that would specify connectivity require- ments for C-ITS, including any 'hybrid approach' that equates IEEE 802.11p with short-range ap- plications and cellular with long-range applica- tions, would run contrary to the principles of the ITS Directive. The Directive says any backward compatibility requirements should not hinder the development of new technologies, in this case 5G, which would go against the core principle of technology neutrality in Europe. "A policy of co-existence should be favored," MacDougall concluded. "A study carried out for 5GAA shows that co-existence of IEE 802.11p and C-V2X at 5.9 GHz would deliver the high- est socio-economic benefits, compared to sce-
