RADIO ACCESS NETWORK
Function
A radio access network (RAN) is part of a
mobile telecommunication system. It implements a radio access
technology. Conceptually, it resides between a device such as
a mobile phone, a computer, or any remotely controlled machine and
provides connection with its core network (CN). Depending on the
standard, mobile phones and other wireless connected devices are
varyingly known as user equipment (UE), terminal equipment, mobile
station (MS), etc.. RAN functionality is typically provided by a silicon
chip residing in both the core network as well as the user equipment.

Deployment
Distributed throughout regions, for example Sumatera Utara,
SUmaterea Selatan, Jawa Barat, etc

Node
› GRAN: GSM radio access network: BSC (Base Station Controller)
› GERAN: essentially the same as GRAN but specifying the inclusion of
EDGE packet radio services: BSC
› UTRAN: UMTS radio access network (3G): RNC (Radio Network
Controller)
› E-UTRAN: The Long Term Evolution (LTE) high speed and
low latency radio access network: eNodeB (evolved Node B)

Vendor
Ericsson, Nokia Siemens Network,
Huawei, Alcatel Lucent, Samsung, ZTE

TRANSPORT NETWORK
Function
A Transport Network connects RAN sites that are distributed
throughout regions to the Core Network. Transport network was
popularly deployed by TDM technologies (E1, T1), ATM technologies
and now IP/Ethernet technologies and optical networks. Microwave
Radio technologies also deployed between Radio sites and BSC/RNC
Sites.

Deployment
Distributed throughout regions, connecting remote regions into
centralized Core Network Sites. For Example transport from
Pangandaran Area to Core Network Site in Bandung.

CORE NETWORK
Function
A core network, or network core, is the central part of a telecommunication
network that provides various services to customers who are connected by
the access network.
Core network centralize the processing/routing/mobility and session
management of UE and act as gateway to the internet for data communication.

Deployment
Centralized in capital cities. For example: Medan for Sumatera Utara,
Surabaya for Jawa Timur.

OSS/BSS/APPLICATION LAYER
Function
Operations support systems (also called operational support systems or OSS)
are computer systems used by telecommunications service providers. The
term OSS most frequently describes "network systems" dealing with the
telecom network itself, supporting processes such as maintaining network
inventory, provisioning services, configuring network components, and
managing faults. The complementary term business support systems or BSS
is a newer term and typically refers to “business systems” dealing with
customers, supporting processes such as taking orders, processing bills, and
collecting payments. The two systems together are often abbreviated
OSS/BSS, BSS/OSS or simply B/OSS.

Deployment
Centralized in capital cities. For example: Medan for Sumatera Utara,
Surabaya for Jawa Timur.

L2 TRANSPORT
VLAN
In computer networking, a single layer-2 network may be partitioned to create multiple
distinct broadcast domains, which are mutually isolated so that packets can only pass
between them via one or more routers; such a domain is referred to as a Virtual Local
Area Network, Virtual LAN or VLAN.

Metro Ethernet
A metropolitan-area Ethernet, Ethernet MAN, or metro Ethernet network is
a metropolitan area network (MAN) that is based on Ethernet standards. It is commonly
used to connect subscribers to a larger service network or the Internet. Businesses can
also use metropolitan-area Ethernet to connect their own offices to each other. An
Ethernet interface is much less expensive than a SONET/SDH or PDH interface of the
same bandwidth.

Optical Networking
Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH)
are standardized protocols that transfer multiple digital bit streams over optical
fiber using lasers or highly coherent light from light-emitting diodes (LEDs).

L2 TRANSPORT

MPLS VPN
MPLS VPN is a family of methods for harnessing the power of multiprotocol label
switching (MPLS) to create virtual private networks (VPNs). MPLS VPN gives
network engineers the flexibility to transport and route several types of network
traffic using the technologies of a MPLS backbone.

QoS (Quality of Service)
The quality of service (QoS) refers to several related aspects
of telephony and computer networks that allow the transport of traffic with
special requirements. In particular, much technology has been developed to
allow computer networks to become as useful as telephone networks for audio
conversations, as well as supporting new applications with even stricter
service demands.

DATA EXPLOSION

Data Explosion

There are multiple factors contributing to explosive growth in
data consumption, but first and foremost is the
combination of powerful mobile computing platforms
and fast mobile broadband networks. Despite the
number of vendors and platform types available on the
device side, the industry is converging on what might be
considered a “standard” platform for smartphones and
also one for tablets.

Data Explosion
The rich
capabilities of
these mobile
platforms
enable them to
consume even
larger amounts of
data through
activities
such as

• music and video
streaming

• social
networking

• cloud-based
synchronization
and applications

• web browsing
and content
downloading.

Data Explosion

Global Mobile Data Traffic Forecast Update, 2011– 2016,” February 14, 2012.

New Smartphones Released every 2 – 4 months!!!

Wireless Technology Evolution

Despite rapid deployments of LTE networks, it will be the middle of the decade
before a large percentage of subscribers will actually be using LTE (or LTE-
Advanced). During these years, most networks and devices will support the full
scope of the 3GPP family of technologies (GSM-EDGE, HSPA, HSPA+, and LTE).

The history of wireless-network deployment provides a useful perspective. GSM/2G,
which in 2009 was still growing its subscriber base, was specified in 1990 with
initial networks deployed in 1991.

The UMTS/3G Task Force established itself in 1995, Release 99 specifications
were completed in 2000, and

HSPA+ specifications were completed in 2007. Although it’s been more than a
decade since work began on the technology, only now is UMTS deployment and
adoption starting to surge.
