Evolution of Telecom System
                     EVOLUTION OF 
TELECOM SYSTEM
INTRODUCTION
 The telecommunications industry is evolving at a dizzying 
rate. 
 In fact, to talk about the telco of the future in 
technological terms is almost fruitless; it’s a moving 
target, and by this afternoon, something will have 
changed.

PAST-TELCOM INDUSTRY
 In the infancy of telecommunications, the process was 
entirely manual. 
 A Lily Tomlinesque operator would manually use patch 
cords to connect telephones within the same exchange, 
which was manageable at the time because there were 
so few phones.

PROCESS OF AUTOMATION
 After many years, much of the process became 
automated. Phones had dials to ring in numbers, Lily 
Tomlin was replaced by a switching system, and 
companies could buy private branch exchanges (PBX) to 
meet their burgeoning telephonic needs.

TODAY-TELECOM INDUSTRY
 Today’s telco deals with a different set of realities. There 
are several  trends behind the abandonment of the 
landline. Chief among them, of course, is the lower cost 
and higher available of mobile technology.

MOBILE USAGE
 Mobile usage is outstripping landline usage, but perhaps 
a more interesting trend is that, even among mobile 
users, data usage is outstripping voice traffic.

FUTURE-TELECOM 
INDUSTRY
 The coming 5G technology will offer 100 gigabits per cent 
connectivity, roughly 1,000 times a s fast as 4G 
connectivity. Interactive data usage is already 
outstripping voice traffic.

VOICE TRAFFIC
 As a corollary, in order for the network to function, voice 
traffic must become data traffic in order to coexist on a 
data optimized network.

DATA TRAFFIC
 Data traffic on Wi-Fi networks is surpassing data traffic on 
cellular networks. Telcos will have to examine their 
architectures to accommodate this shift.

SOFTWARE-DEFINED 
NETWORKING
 The backplane is becoming virtual. Thanks to software-
defined networking (SDN), the jobs of dedicated switches 
and routers can be handled by cheaper, commodity 
computing hardware.

BOTTOM LINE
 The enormous variety, velocity and volume of data that 
can be collected from this traffic geographic information 
system (GIS) data, time of usage, type of usage can be 
used, with advanced analytics, to optimize network 
performance and the customer experience.
