30 no Marketing issues be problematic in that
21 08 2009Hanzo, Vehic. Widespread cellular architecture using single 3G standard, or alternatively multimode phones operating over multiplicity of standards with highspeed access delivered by wireless LAN WLAN solutions in certain important areas. and an Freedom to communicate anywhere It should be possible to have almost any type of communications anywhere, although the higher the possible reduction in the subscriber unit as result of frequencies being reused on very localized level. Since then he has been awarded Ph. D.
Complete unification of all messaging Each individual should have single address which will typically be of the form john. smithmyisp. com some further detail be required to overcome the problem of multiple John Smiths to which all communications will be directed. Economics Provision of some systems, such as radio transmission node in each hotel room, is generally not economically viable and must await lower realizations. Intelligent filtering and redirection Upon receiving message the network, based on preferences and past actions, will determine what to do with it, knowing the current status of John Smith whether mobile, at home, etc..
Marketing issues be problematic in that customers not want to rely on nodes not in their control and not on their premises for their connectivity, and not want their equipment to be relaying messages for others. Adaptive vs. potentially nearly infrastructureless deployment. Highly complex algorithms are required to manage the system and avoid hot spots which be unstable and result in poor availability.
Webb, The Future of Wireless Communications.. However, this be offset by the need for each node to relay traffic. This not always be appropriate, especially when mobile, but the option should be available. Webb, and Hence, if the subscriber is experiencing relatively good SN, perhaps because he is not in fade, more modulation levels can be instantaneously matched to the channel conditions. This is an issue especially for subscriber units. References Webb, Spectrum Efficiency of Multilevel Modulation Shemes in Mobile Radio Communications, IEEE Trans. Webb, Modulation Methods for PCNs, IEEE Commun. It is likely these will be enhanced developments of standards like BlueTooth.
Different and novel medium access control MAC mechanisms be required which will need development and add to the complexity. possible reduction in the subscriber unit as result of each link being short and hence having high link budget. Webb, and Webb, Spectrum Efficiency of Multilevel Modulation Shemes in Mobile Radio Communications, IEEE Trans. Communicator devices able to work on the cellular, home, and office networks in seamless manner. Standardized radio devices in home and office appliances using the same shortrange radio standard. Complete unification of all messaging Each individual should have single address which will typically be of the form john. smithmyisp.
