The 5G is expected to exponentially increase the speed and capacity of wireless communications, while driving the convergence between wired and wireless connections and paving the way for the emergence of a real ‘Internet of Things’.
The European Commission estimates that 7 trillion things will be connected thanks to the next generation of communications system. Computers, cars or fridges will respond to wireless orders and will also be able to communicate among themselves, say experts working towards the 5G revolution.
As a consequence of this surge in connectivity, the EU Executive foresees energy savings up to 90% per service provided. 5G is expected to make equipements, services and entire cities smarter.
Big investments are piling up already now to develop the enabling technologies and to position companies and countries in the new emerging market.
In the last seven-year budget, the European Commission co-funded projects for the roll out of the 4G and the initial development of the 5G architecture. Around €350 million were set aside between 2007 and 2013 to fund research on wireless technologies through projects such as Metis, 5Gnow, IJoin or Tropic.
Many top telecom companies were involved in these projects, including British Telecom, Ericsson, and SAP.
The 7 billion game
The commitments towards the next generation platform have now grown significantly. Last December, the EU Executive signed a number of partnerships with private actors to jointly fund research and innovation in key sectors.
The development of 5G is one of the priority sectors. By 2015, the Commission is engaged to channel up to €125 million for this public-private partnership. This sum will increase up to €700 million by 2020. The private companies involved in the partnership have committed the same amount from their part.
Expectations are however much higher and put the private investment at up to €7 billion. In addition to the €700 million already committed, "the telecommunications industry will invest five to ten-times this amount in activities contributing to the objectives of the partnership," reads a note of the Commission.
These figures are ambitious, include several parallel investment, and their final delivery is far from certain - depending on market conditions and global economic trends. But they certainly do not represent an overestimation of the investment needed.
Outside Europe, huge sums are being hoarded to fund the 5G development. Huawei, one of the main Chinese players, announced investments for a commercial roll-out of 5G of minimum $600 million by 2018. Adding other private actors, and public intervention, the overall Chinese investment is expected to be much bigger.
In South Korea, the government announced a plan to spend $1.5 billion for the 5G, with the objective of increasing wireless capacity 1,000 times more than currently possible with 4G, which in South Korea is already much more developed than in Europe.
Japanese telecoms operators are planning to roll out 5G in time for the Tokyo Olympic Games in 2020.
