Data Add-on Rate Plans: The company offers various optional add-on rate plans that are designed to meet a wide range of subscriber needs with respect to increased data usage that followed the widespread use of smartphones and faster transmission speeds made possible by LTE technology. It offers data plans that offer unlimited data based on time, place and occasion such as its Subway Free plan, which offers unlimited wireless data usage on subway platforms and inside subways and its Commuter Free plan, which offers unlimited wireless data usage during rush hour, each for a fixed rate of Won 9,000 per month.

T Data Coupons range from Won 2,000 for 100MB of data to Won 33,000 for 5GB of data. CDMA and WCDMA Networks: CDMA technology is a continuous digital transmission technology that accommodates higher throughput than analog technology by using various coding sequences to allow concurrent transmission of voice and data signals for wireless communication. WCDMA technology enables the company to offer voice and data transmission and supports more wireless data transmission services than is possible through its CDMA network. Wi-Fi Network: Wi-Fi technology enables its subscribers with Wi-Fi-capable devices, such as smartphones, laptops and tablet computers to access mobile Internet. While each Wi-Fi access point typically has a radius of approximately 20-30 meters, some of its Wi-Fi hot zones, which have multiple Wi-Fi access points, including those installed at public transportation facilities and amusement parks, have much wider service areas. It also has a WiBro network that the company use as a backhaul for its Wi-Fi network. Network Infrastructure The principal components of the company’s wireless networks are cell sites, which are physical locations equipped with transmitters, receivers and other equipment that communicate by radio signals with wireless handsets within range of the cell (typically a 3 to 40 kilometer radius); switching stations, which switch voice and data transmissions to their proper destinations, which might be, for instance, a mobile phone of one of its subscribers (for which transmissions would originate and terminate on its wireless networks), a mobile phone of a KT or LG U+ subscriber (for which transmissions would be routed to KT’s or LG U+’s wireless networks, as applicable), a fixed-line telephone number (for which calls would be routed to the public switched telephone network of a fixed-line network operator), an international number (for which calls would be routed to the network of a long distance service provider) or an Internet site; and transmission lines, which link cell sites to switching stations and switching stations with other switching stations. As of December 31, 2015, the company’s LTE, WCDMA, CDMA and WiBro networks had an aggregate of 55,085 cell sites. The company has purchased all of the equipment for its networks from Samsung Electronics, Ericsson–LG and Nokia Siemens Networks B.V. Most of the transmission lines the company uses, including all of the lines linking switching stations, as well as a portion of the lines linking cell sites to switching stations, comprise optical fiber lines that the company owns and operates directly. The company uses a wireless network surveillance system. Thi
