Evolution Of Gsm: From 2G To 4G Networks

The genesis of GSM traces back to the establishment of 2G networks, which were developed as a substitute for the analog 1G networks. These second-generation digital networks introduced benefits such as encryption for data paths and voice calls, thereby offering a superior level of protection against interference and eavesdropping. Optimized for full ‘duplex’ voice telephony, GSM was initially structured as a digital, circuit-switched network.

Over time, GSM adapted to the evolving needs of users and incorporated data communications. This progression was made possible by the introduction of the General Packet Radio Service (GPRS) and Enhanced Data Rates for GSM Evolution (EDGE). These advancements were transformative in the field of communication, merging data services with high-speed wireless data transfer.

The journey of GSM’s evolution did not stop there. The inception of third-generation (3G) and fourth-generation (4G) networks represented significant leaps in the development of global mobile communication. However, these are not components of the ETSI GSM standard, and were later developed to augment the functionality and speed offered by the 2G GSM network.

Development And Adoption Of Gsm As A Global Standard

The journey of GSM evolving into a global standard for mobile communications is a statement of meticulous planning, international collaborations, and an unflinching commitment to a cohesive vision. Spearheaded by the GSM committee, created by the European Conference of Postal and Telecommunications Administrations (CEPT) in 1983, the purpose was to establish a European standard for digital cellular voice telecommunications.

The first significant milestone in the path of GSM’s widespread acceptance arrived in 1987. Ambassadors from 13 European nations cemented a pact by signing a memorandum of understanding. This treaty aimed towards the creation and implementation of a uniform cellular telephone system throughout Europe, thus standardizing GSM. By marking GSM as a compulsory norm to be adhered to, the agreement solidified its role as the linchpin of the future cellular network infrastructure.

“The journey of GSM’s transformation into a global standard for mobile telecommunications underscores the power of international collaboration and meticulous planning.”

Milestones In Gsm Subscriber Numbers

Leveraging its far-reaching acceptance and utilization, GSM has marked several considerable subscriber milestones since its origin. The cumulative count of global GSM subscribers swiftly surpassed the 100 million landmark within just three years following the formation of the GSM Association (that is, in 1998). This brisk escalation in subscribership serves as a testament to the extensive acceptance and necessity of GSM networks.

In 2000, GSM networks marked another meaningful achievement as they initiated commercial services based on the General Packet Radio Service (GPRS), a pivotal move for mobile data communication. 2004 saw yet another highly significant event when the number of GSM subscribers globally passed the 1 billion threshold, thereby cementing GSM’s market dominance.

Phasing Out Of Gsm Networks: Examples From Around The World

Despite the notable growth and widespread of the GSM networks, several factors, including the emergence of more progressive networks, precipitated their phase-out in certain regions. Telstra, a leading telecom operator in Australia, spearheaded this move, becoming the first to decommission a GSM network on December 1, 2016.

Subsequent to this, AT&T Mobility, another prominent telecommunication company from the United States, followed suit by shutting down its GSM network on January 1, 2017. Equally, the full closure of the GSM network was executed by Optus in Australia come August 1, 2017. April 2017 saw a radical shift in Singapore, where 2G services were entirely ceased.

This gradual discontinuation underscores the relentless progression in the global telecom industry and the shift towards newer, sturdier technologies.

Different Cell Sizes And Frequency Bands In Gsm Networks

To comprehend the architecture of GSM networks, it’s crucial to delve into its unique cell structure and frequency bands. GSM networks consist of various cell sizes, serving to assure connectivity and coverage across diverse geographical terrains marked by differing densities and extents. This cell spectrum includes macro, micro, pico, femto, and umbrella cells.

The constricted cells, specifically femto and pico cells, are predominantly prominent in urban areas congested with populace, providing telecom coverage to smaller geographical divisions. Conversely, macro cells shoulder the responsibility of rendering area coverage in regions of lower density. Also noteworthy is the broad frequency spectrum in which GSM networks function, the carriers predominantly operate in the 900 MHz or 1800 MHz bands.

Voice Codecs And Audio Compression In Gsm

A critical component to the success story of GSM is its voice codecs. These codecs are responsible for compressing audio data in the GSM network, operating at various bit rates that range from 7 to 13 kbit/s.

Particularly, the early GSM networks deployed Half Rate and Full Rate codecs, functioning at 6.5 kbit/s and 13 kbit/s respectively.

Through technological progression, the enhanced full rate (EFR) codec, running at 12.2 kbit/s, was introduced. This new codec offered superior sound quality and marked an important milestone in GSM development.

Alongside the evolution of UMTS – also known as the 3G network, the ERF transitioned into a variable-rate codec dubbed AMR-Narrowband, delivering even higher sound quality on mobile networks.

  • GSM Success: Voice codecs played a significant role in the success of GSM by compressing audio data efficiently.
  • Half Rate and Full Rate Codecs: Used in early GSM networks operating at 6.5 kbit/s and 13 kbit/s, respectively.
  • Enhanced Full Rate (EFR): Introduced later to offer improved sound quality.
  • AMR-Narrowband: The next evolution of EFR with the advent of UMTS(3G network). Enhanced sound quality significantly in mobile networks.

“The evolution of voice codecs – Half Rate, Full Rate, Enhanced Full Rate, and AMR-Narrowband – underscores the dynamic technological advancements, each bringing superior sound quality and efficiency to the mobile networks.”

The Role Of Subscriber Identity Modules (Sim) In Gsm Networks

One of the noteworthy attributes of GSM networks is its adoption of Subscriber Identity Modules (SIM). Integral in enhancing the broad access of telecom services, SIM cards store a user’s subscription information as well as their phone book data. This streamlined data administration substantially simplifies management for service providers.

For the user, these cards facilitate effortless transferability of their data and connectivity between distinct devices. Consequently, the introduction of the SIM card is acknowledged as one of the pivotal advancements towards making cellular communication services more portable, convenient, and user-centric.

Etsi Standards And Governance Of Gsm Systems And Services

The governance of GSM systems and services is a vital aspect to ensure their continuous, effective, and uniform operation. This fundamental governance role is undertaken by ETSI or European Telecommunications Standards Institute. Established in 1988, ETSI oversees various communication standards, with GSM being a prominent one.

ETSI’s responsibilities encompass the standardization of GSM technologies, which involves their development, testing, deployment, and advancement. It manages broad aspects such as formulating the network layout, outlining operation protocols, defining interface specifications, and safeguarding compatibility amongst varied equipment and systems. Consequently, ETSI plays a crucial part in propelling GSM towards its aspiration of a universally connected world.
