Why HTTP, TLS and Transmission Control Protocol (TCP) are inefficient over mobile networks.
HTML, HTTP, TLS and transmission control protocol (TCP) are inefficient over mobile networks because they require large amount of mainly text-based data to be sent over a network.this requirement for large amounts of data to be transmitted is not optimal for mobile networks because mobile networks currently are characterized by lower bandwidths then normal web networks. In addition, any protocols with large data transmission requirement must overcome the difficult challenges of intermittent coverage, another
Characteristic of wireless networks.
HTML Internet standards are not optimal for the wireless web because this standard was not designed for small screen displays and limited input options. WAP does not use HTML to display web sites, but instead uses WML and the WMLScript. WML and WMLScript make optimum use of small display screens where navigation is usually performed with one hand. WAP standards are scalable and can fit into the two-line text displays on the most basic devices to the full graphic screens on the latest smart phones.
