The actual size of cell depends upon several factors like the environment, Number of users and height of Antenna, Power of BTS etc. • In short we can say that cell is smallest radiating unit in mobile network. • A series of cells is used to cover a large geographic area. A cellular system is a mobile network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station. • Each cell uses a different set of frequencies from neighboring cells to avoid interference http://telecomnotes.com/

HSDPA is a new protocol for mobile telephone data transmission. It is known as a 3.5G (G stands for generation) technology which is up gradation • of 3G 3gpp release which is suitable for video calling and mobile TV. http://telecomnotes.com/
