GLOSSARY APPENDIX: Wi Fi and 5G 6 EXECUTIVE SUMMARY Wi-Fi technology is an enabling resource that generates economic value across four dimensions: Supporting the development of alternative technologies, such as multiple access point (AP)/mesh networking systems and smart speakers, that were deve loped leveraging Wi-Fi, thus expanding consumer choice; Supporting the creation of innovative business models, such as Gogo, a leader in the provision of airline broadband access; Expanding access to communications services. Telecommunications companies such as British Telecom (BT) have deployed thousands of Wi-Fi hotspots to enhance connectivity to its fixed and mobile networks; and Complementing wireline and cellular technologies, thereby enhancing their effectiveness. For example, Vodafone Germany operates 1,000,000 hotspots, partly as a complement to its cellular network. There is a significant amount of research-based evidence that Wi-Fi technology has very high social and economic value. Prior research agrees that, contrary to licensed bands where economic value could equate to whatever is paid at auction, the economic value of unlicensed spectrum, such as Wi-Fi, needs to be measured based on the concept of economic surplus and contribution to GDP. Consumer surplus measures the total amount consumers would be willing to pay to have the service compared to going without it altogether, while producer surplus measures the analogous quantity for producers, that is essentially the economic profit they earn from providing the service. Consumer and producer surplus together yield an economic surplus. Adding GDP contribution results in a total economic value estimate. Despite the fact that Wi-Fi is a worldwide phenomenon, most research studies have so far focused only on the United States 1 . The following study goes further and estimates the total economic value of Wi-Fi in six developed countries: United States, United Kingdom, France, Germany, Japan, and South Korea. The studys purpose is to measure economic value, both to consumers and producers, as well as Wi-Fis direct net contribution to output (Gross Domestic Product, or GDP) and employment for 2018 and 2023. The result of this analysis estimates the overall economic value of Wi-Fi for each selected country and is used to extrapolate results to a global scale. All figures are represented in US dollars, except where noted. Using the detailed analysis and methodology explained in the following chapters of this report, the estimated economic value of Wi-Fi in 2018 for the six countries studied is: United States: $ 499 billion United Kingdom: $ 54 billion France: $ 44 billion Germany: $ 94 billion Japan: $ 171 billion South Korea: $ 68 billion Estimates for 2023 represent significant increases in economic value for each market: 1See Thanki (2009), Cooper (2009), Millgrom et al. (2011); Katz (2014a), Katz (2014b), Katz (2018). 7 United States: $ 993 billion United Kingdom: $ 71 billion France: $ 64 billion Germany: $ 132 billion Japan: $ 248 billion South Korea: $ 138 billion Using these six markets and relying on a leading indicators methodology, global economic value of Wi-Fi in 2018 is estimated at $ 1.96 trillion. By 2023, global value of Wi-Fi should increase to $ 3.47 trillion. As a result of the growth and value of Wi-Fi, increases in jobs related to Wi-Fi are calculated. Current estimates show that global jobs attributable to Wi-Fi will increase by more than 50% to nearly one million by 2023. 8 I. INTRODUCTION AND BACKGROUND The debate over the most effective way of allocating frequency spectrum has been conducted over the past seventy years since the publication of Coases seminal paper (1959) on spectrum management. In particular, a key issue underlying the policy debate has been in the past ten years the assessment of the economic value of certain spectrum bands, more specifically the unassigned or unlicensed 2 . Prior research agrees that, contrary to licensed bands where economic value could equate to whatever is paid at auction, the economic value of unlicensed spectrum, such as Wi-Fi, needs to be measured based on the concept of economic surplus and contribution to GDP. Part of the difficulty in assessing the value of Wi-Fi resides on the fact that, unlike licensed spectrum that is used for a few, homogeneous services, Wi-Fi provides the environment for the provision of several heterogeneous services and devices. In 2009, Richard Thanki produced the first paper to determine the economic value of unlicensed spectrum. He estimated that three major applications (residential Wi-Fi, hospital Wi-Fi, and retail clothing RFID) in the United States generated value in the range of $16 and $36.8 billion. At the time, the author acknowledged that these estimates covered only a fraction of the economic value 3and, consequently, were too conservative. Two years later, Milgrom et al. (2011) provided additional support to Thankis numbers, but also calculated value estimates for other applications. For example, the authors estimated the economic value of Apples iPad, a device intimately linked to the use of Wi-Fi, at $ 15 billion. Additionally, the authors quantified other benefits in the United States alone, such as Wi-Fi supported cellular off-loading ($ 25 billion) and the value of Wi-Fis faster data rates compared to cellular service ($ 12 billion). A year later, Thanki (2012) produced a new piece of research, refining his residential Wi-Fi estimate and quantifying other benefits of unlicensed spectrum. He estimated the annual consumer surplus of residential Wi-Fi to be between $118 and $225 per household 4(a total of $ 15.5 billion for the United States). Additionally, enlarging the original scope of benefits, he assessed the producer surplus derived from carrier savings resulting from Wi-Fi off-loading ($ 8 . 5 b i l l i o n f o r t h e U n i t e d S t a t e s ) . F i n a l l y , h e e s t i m a t e d t h e v alue generated by enhanced affordability (an assessment mainly focused on emerging markets) and mentioned potential innovation related benefits related to deployment of Wireless Internet Service Providers. In the same year, Cooper (2012) calculated Wi-Fis economic value by estimating the number of cell sites that the wireless industry would avoid investing in as a result of traffic off-loading (130,000), which would result in annual savings of $26 billion. The author also updated Thankis residential wireless consumer surplus as a result of the considerable increase in Wi-Fi adoption that had taken place since 2009. Th e au th o r o f th is stu dy h as c onducted three successive studies on the economic value of unlicensed spectrum in the United States for 2013, 2014, and 2017 (the last one complemented with a forecast for
