Rental fees for local leased lines are generally based on transmission speed while domestic long distance leased line rental fees are generally based on transmission speed and distance. 

We continue to experience a decline in rental fees for all of our leased line products. The decline in rental fees since 2000 has been substantial partly as a result of broadband services substitution and other service providers constructing their own lines. In response, we continue to implement marketing and service campaigns to retain our high-value corporate customers. 

## Wi-Fi Services 

We launched our wireless local area network service in May 2002. As of December 31, 2011, we had a total of approximately 657,007 residential and business customers that lease our access points. In addition, we have established 21,216 hot spots in public areas, such as convenience stores, airports and international convention centers, where individuals can access our wireless local area network. 

## Multimedia on Demand Services 

We launched our multimedia-on-demand, or MOD, service in Taipei County and Keelung City in March 2004. We have expanded this service to all 18 counties and cities of Taiwan in December 2007. Using video streaming technology through a set top box that connects to our FTTx and ADSL data connections, our customers can access TV programs, VOD and other services. We had over 133 broadcasting channels and over 12,000 hours worth of on-demand programs and served approximately 1.05 million customers as of December 31, 2011. In addition, our video-on-demand service provides movies, dramas, animations, documentaries, e-learning and music programs for home entertainment. Also, we currently offer 43 high definition, or HD, channels and other HD video-on-demand programming, such as sports, movies and knowledge materials. We offered “family package” channels in 2010 to enhance our service content and satisfy our customers’ needs. MOD revenues accounted for NT$0.9 billion, NT$1.1 billion and NT$1.4 billion (US$47.4 million) in 2009, 2010 and 2011, respectively.
