Marketing issues

•From a reactive marketing:• existing market demand

(services);• development of new

technologies (networks);• Time-To-Market

constraints.•To a proactive marketing:

• existing technological opportunities (networks);

• offering of new services/applications.

The best way to foresight the future market is to create it


Marketing issues

• Generalized market with product differentiation:

• worldwide dimension;• economies of scale and

scope;• offering of personalized

services/applications.

Customer orientation in a mass market environment

Customer orientation in specific market segments


Marketing issues

•Market segmentation:• identification of client

classes;• definition of potential

market targets;• targeted offering of

services/applications.Identification of the most convenient technical solutions for each market segment

DIFFERENT KINDS OF MOBILE SERVICES

Fixed-Mobile ConvergenceFixed-Mobile Convergence


“Picocells” at the interior of buildings:• around 100 metres of coverage• low cost cordless phones (e. g. CT2 or DECT)• low tariffs• extended cordless capabilities

“Microcells” at the interior of cities or local areas:• around 1000 metres of coverage• cordless (DECT) or mobile phones (TACS, GSM/DCS)• new kinds of tariffs• mobile or extended cordless capabilities

DIFFERENT KINDS OF COVERAGE



“Normal” cells at national or continental level:

• up to 10000 metres of coverage• mobile phones (TACS or GSM)• normal mobile tariffs

“Macrocells” at worldwide level:• worldwide coverage• satellite phones (Iridium, Immarsat,

Globalstar, Teledesic/Celestri)• new satellite mobile tariffs

DIFFERENT KINDS OF COVERAGE



•PERSONAL PHONES WILL REPLACE AN INCRESING NUMBER OF TRADITIONAL WIRED PHONES.

•CELLULAR NETWORK HAVE A PECULIAR ADVANTAGE BECAUSE BOTH THE CAPACITY AND THE COVERAGE MAY BE PROVIDED BY HiERARCHICAL CELLULAR NETWORKS
