Forum.Nokia.com 2.3.4 Infrastructure optimization The latency between the WAP gateway and content server should be minimized. Each query traverses this link twice, once as a request and once as a response. The WAP gateway should be placed close to the GPRS gateway. (The GPRS gateway is technically called a “Gateway GPRS Support Node,” or GGSN.) “Close” in this instance refers to both latency and the probability of packet loss. Lost messages cause additional delays due to HTTP retransmissi

Forum.Nokia.com 2.4.5 The first screen The first (topmost) screenful of any page is the most important. All often-used navigational links, search fields, login screens, and the bulk of the information should reside there. The user can then navigate forward before the rest of the page has been loaded, and will not have to scroll the page. Wasting the top of the page on banner advertisements or non-informative graphics should be avoided. It is better to place advertisements at the left or

Forum.Nokia.com Proportional fonts are used in header text, and if the header text is too long, it is cut automatically. Cut titles are usually better than abbreviations, because the user may be confused by unfamiliar abbreviations. Although short words are recommended for element labels, acronyms that are not well known by the target user group should be avoided. The same label should always be used for the same thing, especially with function labels such as Delete, Remove, Erase, Clear,

The main focus is on the WAP services element (WAP browser) of the phone. The WAP browser user interface is designed to comply with the user interaction handling known from other applications in the phone.

It provides an overview of graphical user interface elements, that is, the WML elements that are critical from the rendering point of view and their WML capabilities supported by the browser. The document does not include all possible WML elements and attributes. WAP service developers should pay special attention to Sections 4.2: Table and 4.3: Images. The WML

If the items cannot be displayed on the same display, the user is not given any notification. Fieldset always starts a new line and ends with a line break. 4.1.4 Pre element The pre element is supported.
