A. Dimensions of the Wireless Market
Past, Present and Future Growth Wireless Subscribership: June 1985-June 1997
The wireless industry has witnessed incredible growth 5300.,000000.,000
in its short history as a commercial service. The first 25.000.
statistics compiled by CTIA in late 1984 showed
15.000.
approximately 92,000 subscribers nationally. By the
000
end of 1990, there were just over 5 million subscribers,
000
and from the most recent statistics of mid-year 1997, 20000000
.
there are now over 50 million subscribers. To put this 000
in perspective, there are now far more wireless sub- 10.000000
5,000,000
scribers in the United States than there are people in
Canada. The industry has continually posted annual 85 86 89 90 91 95 96
subscribership growth rates ofover 30%, and with the Source: CTIA
recent introduction of Personal Communications Cell Sites in Commercial Use: June 1986-June 1997
Services (PCS), this trend shows no sign ofslowing.
40.000
35.000
Industry “experts” have historically under-predicted
30.000
the growth ofthe wireless industry. That said, howev-
25.000
er, some industry observers are forecasting anywhere O
20.000
from 70 to 80 million subscribers in the United States in
15.000 .in
by the year 2000. This growth is coming from a new
10.000
set ofsubscribers. In the past, the typical wireless sub-
5,000
scriber was seen as the busy executive whose business
might pay the tab. No longer: now, most new sub- 95 96 97
scribers indicate that theywill be using their phone for Source: ctia
personal use. Furthermore, a large percentage ofusers subscribe to wireless service solely for safety and secu-
rity reasons. Finally, the wireless subscriber is becoming increasingly “mobile,” in that subscribers are now
purchasing more portable, “pocket” phones than vehicle-installed mobile phones.
The infrastructure ofwireless networks has grown in step with subscribership. By the end of 1990, the wire-
less industry had invested over $6 billion in its infrastructure; as ofmid-year 1997, cumulative capital invest-
ment by the industry stood at over S37 billion. A great portion of this money goes toward construction of
the antenna sites that are the backbone ofthe wireless network. At the end of 1990, there were approximately
5,600 cell sites in the United States, and most recently, the number of cell sites had risen to over 38,000.
Clearly, the surging demand for wireless services has driven the growth in cell site placements.

Wireless Local Loop
The future ofthe wireless marketplace will likely involve non-mobile subscribers. Although wireless networks
wrere initially intended to provide the user with unlimited mobility, wireless technologies can also provide local
phone sendee to fixed locations. Wireless Local Loop (WLL) senice is simply a connection to the public tele-
WLL
phone networkvia radio frequencies rather than via traditional copper wires. In many cases, may be the
only means ofreaching a subscriber. It can also provide the telephone customer with an additional choice for
local phone senice. In the near future, wireless phones mayindeed replace wiredphones for ones primary tele-
phone senice.
Geographic Dimensions of Wireless Service Coverage
During the earlyyears ofthe industry, wireless companies sought to provide senice where their customers
traveled, i.e. along major roadways. Ofcourse, this level ofsenice was also bom ofnecessity as the size of
the phones limited them to being installed in vehicles. As the industry matured, phones became smaller
and more portable, while the senice providers expanded coverage areas. In addition to city centers and
