m-Commerce Heavily hyped Customers have limited capability mobile phones – technology

limits user experience quality-no replacement for e-commerce-only for urgent business with simple interaction

Areas of expected success Purchase of goods for mobile unit: games and ringtones Mobile banking=internetbanking + direct payment Information services: weather, news, sports <-SMS or WAP Location-based services: Where is the nearest restaurant – privacy

issues Mobile shopping – for items needed on the fly: tickets, comparison

shopping Mobile advertising – normaly no place on device, but perhaps on

demand in connection with locality. Technical inhibitors: Small screen, inconvenient input, slow

network Business inhibitors: Lack of compelling applications

m-Business Technology used to support mobile work

Updated information, Cooperation over distance, Data-entry in the field Uses high-end mobile equipment with better capabilities (smart-phones,

PDA, Pocket PC,Tablet) Communication cost is usually not an issue

Examples Mobile office connected to backed server for e-mail, appointments and

address information Field sale mobile equipment supports updated and update of information in

sale situation Field service provides customer, procedure and installation information Transportation and logistics vehicles with mobile and wireless equipment

can inform main office on location and can be informed on new dispatching, packet status etc..

Enablers Wireless network development

Augmenting bandwidth Falling costs Always on WLAN – hotspots New services

Mobile Devices Fast development More connectivity,computing power and autonomy, but lower size, weight and cost More functionality – camera, mms, radio, gps, compass But still relatively low resolution screens and inconvenient input

Software Infrastructure Mobile internet – wap, device emulators Smart Clients – .NET CF and J2ME

mobile databases, synchronization technology Standardization

WAP, WAP2.0, XHTML, VoiceXML, Sync ML, WLAN, Bluetooth
