Evolution of Telecom Industry.
                     EVOLUTION OF 
TELECOM INDUSTRY
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.
