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

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.

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).

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.

4G LTE Technology OverviewDATA 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.

4G LTE Technology OverviewWireless 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.
