Worldwide Service Provider WiFi Infrastructure 2013?2017 Forecast: Poised for Continued Growth

This IDC study provides a five-year forecast (2013?2017) for the worldwide service provider (SP) WiFi network infrastructure market. Data for 2013?2017 is forecast This study includes WiFi radio equipment installed for use as part of service provider networks, including mobile, converged, and cable operators. The forecast does not include related services, nor does it include deployments by service providers in enterprise deployments such as for hotels and retail establishments. The forecast also segments the market by geography: North America, EMEA, Asia/Pacific, and Latin America.

According to John Byrne, research director for IDC's Wireless Network Infrastructure, "Service providers continue to deploy WiFi wherever feasible, resulting in an explosion in the pace of both deployment and related spend on SP WiFi. IDC forecasts SP WiFi spending will grow to $931 million in 2017. However, despite rapid growth, SP WiFi spending will continue to pale in comparison to spending on traditional cellular gear. As a result, cellular vendors are struggling with how to embrace WiFi while still preserving their traditional bread-and-butter businesses in cellular radio and core equipment and services."

South Korea - Mobile Market - Overview, Statistics and Forecasts

South Korea?s mobile market passed the 110% penetration rate mark into 2013. With all three mobile operators having merged the fixed and mobile sides of business in 2011, triple-play was promoted more actively. The introduction of converged services across the fixed-line, mobile and broadband infrastructure has resulted in more attractive bundled pricing for consumers. LTE was launched in 2011 and saw fast growth into 2013, accounting for over 20% of all subscriptions. This report provides an overview of the dynamic mobile market in South Korea and includes a summary of the mobile technologies, associated subscriber statistics down to operator level, and a number of mobile applications proving popular in the market. Mobile forecasts are included to 2017.

Key Developments:

Mobile penetration over 110% and ARPU around US$25; launch of LTE and testing of LTE-Advanced; introduction of MVNOs in 2011; smartphone adoption rising to over 20 million subscribers and 40% of the mobile subscriber base; an 11-fold jump in mobile data traffic over a one year period; Wi-Fi traffic accounting for a third of all mobile traffic; drive for NFC chips in smartphones; first ever spectrum auctions as 2G frequency bands expired; launch of HD voice over LTE (VoLTE) by SK Telecom; a reported minimum 50% increase in monthly data usage on LTE compared with 3G; uptrend in ARPU driven by demand and LTE pricing.

Companies covered in this report include:

KT; LG U+; SK Telecom.

Have you ever wondered what all of those different names really mean? In this edition of How Stuff Works we will look at the radio spectrum and see what is really going on!
IBM Who gets the 3G spectrum? (11/01) Government's new plan for 3G spectrum is a mixed bag for wireless providers. 3G could provide us with easy access to an incredible range of new telecommunications services. In order to provide those services, however, wireless companies must be able to access a significant amount of spectrum that is currently dominated by government and other commercial interests. Technology writer Dana Triplett uncovers the latest plan from the federal government for assessing spectrum use, offering an inside look at the players in the struggle for the invisible but valuable commodity of radio frequency in the U.S.

ITU Radio-Frequency Spectrum Publications The Radiocommunication Sector acts as the coordinator in managing the usable radio-frequency spectrum efficiently, keeping it free from harmful interference, and adopts international regulations and treaties governing this use.

NATO Cooperation in Radio Frequency Management (2000) Cooperation between NATO member countries in the use of radio frequencies for defence purposes is underpinned by a common commitment to collective security and defence. The availability of radio frequencies is essential for the armed forces' operational readiness and effectiveness and the NATO-wide standardisation and coordination of frequency allocations is vital to ensure interoperability among multinational forces.
NTIA US National Spectrum Requirements: Projections and Trends The availability of radio spectrum in the United States is critical to many telecommunications services, ranging from cellular telephones to air traffic control. Although spectrum is not a consumable resource, the use of a frequency at a given location usually excludes that frequency from being used by others in the same geographic area. This need for exclusive geographic use has led to current spectrum regulations that establish exclusivity in spectrum use by granting licenses for spectrum use, and the partitioning of the spectrum for shared use between radio services.

ZDNet Overcrowded Airwaves A kind of air traffic control may be needed to manage our ever-expanding wireless communications. Wireless networking has been touted as an ideal solution for a wide range of communications problems -- synchronizing PDAs with desktop PCs, eliminating printer cables, creating in-building LANs, connecting buildings on a campus and even spanning the "last mile" -- the distance between a connected PC and telephone company or ISP. But wireless has its dark side: interference. As wireless devices proliferate, we will see more and more "midair collisions." To understand why, you need to understand the politics, economics, and technology behind today's wireless networking equipment.
