UMTS LTE cells and network.

What is a wireless cell, cellular tower, cell site and cellular network in general ?
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.

Interview Questions.

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.
