Introduction

• We are going to observe the wireless phone
  industry to understand the context of the firms.
• We will also examine the financial data,
  customers, technology, and markets of the firms
  to paint you a picture of rapid technology change
  and growth.

History of Wireless Phones

• Wireless communication essentially began around
  100 years ago, when Guglielmo Marconi received a
  Morse code signal sent from across the Atlantic
  Ocean, providing that radio waves do not travel
  in a straight line, but move with the curve of
  the Earth.

Advancements in Wireless Technology

• Wireless phones use radio waves to transmit a
  signal from a phone to a low-power transmission
  tower which then directs the signal to the
  destination
• Radio waves travel at a certain frequency along
  the band in the electromagnetic spectrum that is
  used to transmit audio, video and data
  communications.

6
The Digital Age

• Digital technologies have now been developed
  using the same theory of cells, but allowing more
  simultaneous users by compressing the data, and
  more effectively using the available radio
  frequency.

Cellular Towers

• Originally there might have been only one tower
  per city allowing limited usage.
• Now there are several towers towers dividing
  areas into small cells to allow for many
  concurrent users on an analog network.
