  • Patent number: 5953675
    Abstract: The invention relates to a method for processing information in a wireless local loop (WLL) terminal and a WLL terminal. According to the present invention, a WLL terminal comprises a display device, and character-based information, first data, is converted to second data for displaying it on the display. Said first data is advantageously converted in such a manner that a bitmap (222) is first formed on the basis of the character-based first data and then a line code (223) is formed on the basis of said bitmap. The line code is transferred (224, 225) by means of known facsimile transmission technology to a fax machine serving as a display device and displayed by the fax machine (226). The invention can be applied in wireless local loops to implement services that use information in character format. Such services include the short message service and display of caller data.
