A cell is a area of land covered by a radio tower. A radio tower is vertical mount with installed transceiver's. A transceiver is responsible for sending and receiving radio signals over air.  The area covered under a particular cellular tower is known as its cell site. When multiple cell sites interact with each other and with multiple mobile devices a a wireless cellular network is established.  
UMTS LTE Cells and Network Deployment.
Introduction: LTE is an evolved technology on the wireless evolution path shown below:

GPRS –> EDGE –> UMTS –> evolved 3G capabilities such as HSDPA, HSUPA, HSPA+, IMS –> 4G LTE

During the above evolution path many of the core components involved in all-IP LTE were developed and deployed.  
Feasibility of LTE Network and 4G mobile devices: The first generation LTE products should supports multiple standards from the 2G/3G/4G evolution path above.  Current phones supports multi-modes by inter-connecting multiple chip-sets on hardware. Also the re-use of current cell sites are allowed in LTE architecture.

Future Topics:
UMTS LTE UE cell search and cell selection.
LTE broadcast of system information.
LTE cell selection and re-selection.
