Infrastructure in a Telecoms Network
©3G4G
• In a simple Telecom network, the infrastructure would consist of all the
physical (hardware and software) components that can be used by the
mobile operator/service provider to provide services.
• Another way to describe an Infrastructure is that it is a physical
network that can be used by Service Providers to provide Services
‘Service Provider’ vs ‘Mobile Operator’
©3G4G
• Service Providers are also known as Telecommunications service
provider (TSP) or Communications service provider (CSP). Basically,
they refer to someone who provides services.
• A common example would be Internet Service Providers or ISP who
provides internet via cable or ADSL or Fiber, etc.
• Cable TV Providers, providing TV and other broadcast content were
originally referred to as Cable Service Providers.
• Mobile Network Operators are also referred to as mobile service
provider (MSP) or wireless service provider (WSP).

• Here SP3 is using Infrastructure from multiple companies like IB and IC.

Scenario 3 Example: AT&T, USA
©3G4G
• US Operators have to partner with multiple tower companies
(infrastructure providers) due to the large geography and different
rules for different states / counties
• AT&T has been working with multiple partners for example:
• Tillman Infrastructure
• Crown Castle
• Cityswitch
