Understanding 3G Telecom Evolution Through "Cladistics"
November 13, 2002 - source: Catapult
Communications
Recognizing that 3G has many roots in earlier technologies, one
useful way to understand 3G telecom evolution is by applying the
concepts of "cladistics." In an article by Guy Simpson, Vice President
Applications Development, Catapult Communications, it suggests using
cladistics to describe 3G standard development path.
Cladistics is a concept from evolutionary biology that uses family
trees to help understand relationships between family members. By
identifying "primitive" characteristics (that are inherited from
a common ancestor and belong to all members of a group) and "derived"
characteristics (that are advanced traits that can be found only
in some members of a group), clues may be found regarding future
evolutionary relationships. Figure 1 is a simple cladistics diagram
that shows the evolution of the transportation industry. In this
diagram, "wheels" is a primitive characteristic while "engine" and
"wings" are derived characteristics.
Figure 2 is a cladistics diagram that shows the evolution of 3G
UMTS technology -- the primitive characteristic is GSM, a common
base of technology that all members of the group support. GPRS,
EDGE and UMTS are derived characteristics and are progressively
supported by 2.5G, 2.5G+ and 3G technologies as shown.
If we focus on just the 3G-UMTS world as in Figure 3, we can see
how the technical specifications and standards are evolving. It
should be noted that the 3GPP organization has the primary responsibility
for setting standards for 3G UMTS and that new technical standards
are being issued every 3 months. So unlike the evolutionary patterns
and processes spanning billions of years revealed in biological
cladistics, the telecom industry is evolving at an explosive and
ever faster rate!
