The digital textbook is a suitable medium for the\r\nprovision of customized education that fits each individual�s\r\nneeds, and for the ongoing changes in educational needs\r\nsuch as a self-directed learning ability. This paper reviews\r\nselection criteria for the wireless network to be applied to\r\ndigital textbook. At present, it is believed that wireless LAN\r\nwas selected for the digital textbook in Korea because it provides\r\na better data rate and greater cost-effectiveness than\r\nthe other wireless network technologies. However, wireless\r\nLAN is inferior to the other technologies in terms of mobility\r\nand security. The future wireless network for digital textbook\r\nwill be guaranteed that it can meet the requirements\r\nof data rate and mobility. Therefore, for the digital textbook\r\nwith characteristics of public welfare, it would be worthwhile\r\nto consider allowing the installation and operation of\r\nthe internal mobile WiMAX network.
