Bf=2(fh-fl)/fh+fl As UWB has very large instantaneous bandwidth hence it offers substantial increase in channel capacity‚which can be perceived from

user to come up with a good initial description of the data in an enterprise. A database design in terms of a semantic model serves as a useful starting point and is subsequently translated into a database design in terms of the data model the DBMS actually supports. A widely used semantic data model called the entity-relationship (ER) model allows us to pictorially denote entities and the relationships among them 1.5.1 The Relational Model The central data description construct
