At this stage we are facing different types of problems and threats to the mobile industry, the two major aspects are the security and the usability issue. Detailed analysis of security issues is very important at least for a mobile wireless device, there are numbers of ways that it can be compromised, but I would like to draw an attention on the usability issues as well. They both need to be carefully planned and designed that the mobile user or target audience get used to it easily, effectively and securely.
This paper provides a brief information and discussion about the issues relating to design of a mobile device. According to my aims and objectives of this paper I have done the detailed research and get the knowledge about it and the factors that need to be consider carefully. This paper also provides the technical discussion about designing issues of mobile computing that will definitely help me and sharpen my skills in this domain. Its also provide us information about how we can improve our designs and the security features in the wireless networks but this paper does not particularly focus on the in-depth detail about the security aspect for example: encryption and the requirements for enhancements of network architecture.
