The Internet has now become mobile. Mobile terminals and handsets for mobile Internet are emerging. This paper discusses how professionals like energy supervision operators and service technicians can use the new technique. The paper also describes an implementation of a supervision system built with the Wireless Application Protocol, WAP. The technique gives availability everywhere, for an operator on duty at home or on his way between sites. Mobile terminals can also replace the display included in equipment on site; perhaps in the future mobile terminals will be a standard interface to equipment. Via the mobile Internet, service technicians can obtain descriptions and instructions while they are in the field. An important requirement for this development is of cause that the security and reliability aspects will be solved satisfactorily. The paper describes how the WAP technique is applied in an embedded supervision computer on a telecom site. How to create intuitive and simple dialogs is discussed and also the adaptation to different types of mobile terminals and devices with significantly different resources e.g. screen size. The possibilities of the immediate future will also be discussed. What will be the impact of the new techniques in the mobile networks: Packet radio (e. g. GPRS/EDGE) and third generation (wideband) mobile Internet. Other carrier techniques for more local applications e. g. bluetooth will be discussed as well as related techniques like mobile location solutions and machine to machine communication over mobile internet.
