Inhibitors:
- New entrants : Given the seamless service, chances are fixed connectors (ISP) and WIFI providers. The providers can relatively easily enter the market through using the conventional communicator for land line, existing WiFi bases and so on.
- Consumer: Difficult to change their perception from mere "mobile phone" to the seamless service. What is the advantage for consumer to buy these products? Can normal consumer understand the advantage of seamless services?
- Industry rivary: The competition will be intense for the vertical or horizontal integration among the ISPs, mobiles, fixed lines and WiFis. Need for scale of economy to lead the industry standard, cost leadership, infulence to the government and regulatories and absorbtion of the contents provider.
- Security issues: Given the wireless communication through mobile phone, the invasion of the privacy will be an issue. Development of SSL for mobile commerce or development of sophisticated code for communication should be developed.
Paradigms:
- The seamless service among mobile, fixed line, WiFi and ISPs will drastically change the industry structure. The four separated industries integrated one market, resulting that the companies in the industries will face the new competitors, convergence, intense sharing the cotent providers and related M-commerce providers.
- Social life style will also change. The Mobile phone will have bigger monitor so that customers can watch the TV or play online games through the mobile phones. In Japan, the fixed fee structure for packet communication established already, therefore, the cost of mobile communication will be no longer a problem for customer. Communication between the people may also change, the video e-mails, shopping through the mobile phone, listening the music through mobile phone (substitute of MP3 player) and all contents or services provided currently through internet will turn to the mobile services.
