The digital textbook is a suitable medium for the provision of customized education that fits each individual's needs, and for the ongoing changes in educational needs such as a self-directed learning ability. This paper reviews selection criteria for the wireless network to be applied to digital textbook. At present, it is believed that wireless LAN was selected for the digital textbook in Korea because it provides a better data rate and greater cost-effectiveness than the other wireless network technologies. However, wireless LAN is inferior to the other technologies in terms of mobility and security. The future wireless network for digital textbook will be guaranteed that it can meet the requirements of data rate and mobility. Therefore, for the digital textbook with characteristics of public welfare, it would be worthwhile to consider allowing the installation and operation of the internal mobile WiMAX network.
