Systems (PCS). This second generation (2G) of wireless technology primarily supported
a digital signal, which audibly was clearer than the analog signal. The handsets were a
fraction of the size of the 1G cell phones and the first handsets provided expanded
services such as paging and the ability to send text messaging through the handheld unit.
However 2G had some network functionality trade-offs. The technology of 2G included a
static free signal but with a higher rate of disconnects or dropped calls thus the
deployment of 2G required significantly more base stations for several reasons. First, the
propagation signal in 1900 MHz is limited to a 2-4 mile range so the number of required
base stations almost tripled just to provide basic 2G coverage in the same geographic area
as a 1G service area. Second, the industry was reluctant to share tower space with a
competitor and many service providers resisted collocating on the same tower. Third,
subscriber base and usage grew rapidly and the industry needed more sites to improve
network coverage demands by their customers.
Third and fourth generation (3G and 4G) wireless handsets offer a wide variety of tools
and services including access to e-mail, news, music and videos; built in cameras and
videos; global positioning services (GPS); internet commerce; and thousands of
applications from games to flashlights for downloading onto the handset. These
applications require large amounts of bandwidth and service providers continue to
upgrade existing base stations and add additional base stations
to improve and increase network capacity. To improve network
functionality service providers purchased licenses to operate in
the 1700-1800, and 2100-2400 MHz frequencies.
The operating footprint is similar to the 1900 MHz footprint
and helped to increase bandwidth in smaller geographic areas.
With the advances of 4G the service providers are purchasing
licenses in the 700 MHz frequencies. The 700 MHz platform
has a service area similar to 800 MHz and will allow the service
providers to broadcast a larger propagation footprint. The need
for additional infrastructure for 3G and 4G is significant
nationwide and continuous deployment of new base stations
will be necessary as the industry transitions to fifth and sixth
