Always Forward With Our Superior Technology
We are ready for the future with our converged network!
With the investments and efforts made within 2015, we have brought our mobile and fixed networks even closer with the power of our widespread fiber infrastructure. While maintaining our technological leadership in competition with our convergence vision in both our core network and access infrastructures, we have advanced our quality of service and service levels offered to our customers. With our converged network, we can offer innovative services to our customers with attractive business models. The delivery of all necessary telecom solutions for digital transformation of our corporate customers from a single-point has become possible. We have made our operations more efficient through significant optimizations in investment and operational costs with collaborative network management.
THE FASTEST OF 4.5G: TURKCELL!
We secured the largest spectrum at the tender held on August 26, 2015, obtaining a total bandwidth of 172.4 MHz. With this tender, Turkcell owns 43% of the total available spectrum, reaching a total spectrum of 234.4 MHz. The new spectrum acquired is technology neutral and may be employed in 2G, 3G, 4.5G and future 5G networks.
Having gained 13 years of authorization with the spectrum tender, Turkcell will begin to provide 4.5G service to its customers on April 1, 2016. At the launch, we will be the only operator providing up to a 375 Mbps speed experience to our customers with our spectrum, and will remain the fastest operator in comparison to our competitors by providing speeds of 1 Gbps and above in the upcoming periods as technology develops. With 2x10 MHz, which we acquired at 800 MHz, we will rapidly enable coverage across wide areas and within buildings.
At the tender, we purchased the C1 package, the largest package at 1800 MHz, gaining 29.8 MHz. 1800 MHz, the most commonly used spectrum in the world for 4.5G, is the most efficient spectrum both in terms of coverage and capacity, and is also the spectrum with the most widespread terminal support. By means of purchasing an additional 2x10 MHz at 2100 MHz, we have secured the highest bandwidth within this spectrum, which we may use both in 3G and 4.5G. We will notably be able to employ our 2600 MHz FDD and TDD spectrum in additional capacity requirements, and also in hotspots and within buildings for a high speed experience.
We have expedited our infrastructure investments for the best 4.5G service.
In 2015, we had worked intensively to prepare our network to provide the best 4.5G service to our customers. We have prepared the infrastructure of our fields for the set-up of 4.5G base stations, and the set-up has already begun.
We continue with 4.5G preparations in our mobile subcarrier network. We are increasing our mobile subcarrier network capacity to 10G using the power and superiority of our fiber infrastructure. Thus, we will provide infrastructure to support an escalation of speeds up to 1000+ Mbps with 5-carrier aggregation using our frequency superiority in 4.5G. We are establishing the infrastructure necessary to enable value-added services in 4.5G, and that will meet our future requirements.
We have made our core network infrastructure compatible with 4.5G. We have determined the most suitable technologies and products with our 4.5G trial networks.
Next Generation HLR/HSS structure is in service & 4.5G HSS readiness is completed.
Next Generation HLR/ HSS structure has been renewed from legacy HLR structure which stores each customer profiles and authorizes service requests from customers. NG HLR is a central database for all the 2G, 3G and also 4.5G customer profiles. Thus, network efficiency, operational flexibility and high service availability are obtained. Turkcell is the first operator to complete this critical transformation in our country. Common database will allow us to easily reach our customers with enriched and integrated services in 4.5G technology.
Turkcell subscribers experience LTE/LTE-A abroad.
Having made the necessary preparations, we have made it possible for Turkcell customers who travel abroad to communicate at 4G speed.
As of 2015, Turkcell customers are able to use LTE/LTE-Advanced technology in 52 countries with 70 operators.
OUR TESTS SET A RECORD WITH A SPEED OF 1200 MBPS.
In tests conducted using the 5-carrier aggregation technique in December, we set a record by reaching a speed of 1200 Mbps. Turkcell subscribers will experience this speed, attained in the test conducted with the bandwidths that will be the most preferred for the highest speed and largest capacity in 4.5G, once the terminals supporting this technology are in place. They will then enjoy a 19 times faster mobile internet speed compared to 3G speed of 63.3 Mbps.
Turkcell became the first to test the “Enriched VoLTE” service in Turkey.
In 2015, we were the first operator in Turkey to test “Enriched VoLTE” technology, which provides a brand new call experience via 4.5G. In tests conducted together with Ericsson, besides crystal sound quality and the ability to make calls instantly with VoLTE, we successfully displayed enriched services such as the ability to draw on the display image simultaneously with the call, to start a call by adding a message, photograph and location and to make an HD video conference call.
Once again, Turkcell became one of the first operators in the world to test LAA, which is part of 4.5G technology.
We are also now among the first operators in the world to test LAA (License Assisted Access) technology, which simultaneously uses licensed and unlicensed bands with the Carrier Aggregation technology in 4.5G. LAA, the standardization of which will be completed with 3GPP Release 13, is expected to initially be used in small cells on 4.5G networks as the device and network support become ready over the coming years.
TURKCELL IS THE LEADER IN 5G AS WELL!
Through the 5G agreements with Huawei, Aselsan and Ericsson, we have also proven our leadership in 5G. In Turkey, we play an active role in supporting 5G Research and Development activities, whereas in the international arena, we take part in the 5G activities of NGMN and GSMA.
We have signed a mutual memorandum of understanding with Huawei for cooperation in collaborative work and research and development on 5G technology. While taking our strategic partnership to the next level within the scope of the signed memorandum, we have also taken an important step in determining the opportunities to increase future cooperation for research and development, especially of 5G technologies.
With Aselsan, we aim to render Turkey a 5G technology producer country. Accordingly, we will work on the course of 5G technology, ensure participation in international standardization processes and make a joint effort toward commercial success in local and international markets with products to be developed.
With our cooperation with Ericsson, we aim to develop mutual understanding regarding the use, requirements and implementation scenarios of 5G. We believe that this cooperation will make it easier for us to focus on the requirements and expectations of consumers and corporate customers from different sectors.
OUR INFRASTRUCTURE INVESTMENTS
We are among the leading telecommunication players in the world with our transmission infrastructure.
Being one of the few operators in the world to integrate “Full Outdoor” products with our radio link infrastructure, we have shown our leadership in using technology, while also reducing our energy consumption. We enabled the first commercial WSON (wavelength switched optical network) application in the world, independent of direction and wavelength, which was brought to life in 2011 on the Istanbul subway network, to our entire network in 2015.
We are successfully testing Terabit capacity DWDM (Dense Wavelength Division Multiplexing) systems, allowing an increase in the capacity of our current fixed network fiber infrastructure by 2.5 times, and we continue necessary investments in building and expanding the infrastructure compatible with this technology. We use state-of-the-art systems in our fixed network and are ready to implement future technologies.
We have increased customer satisfaction with improvements to our infrastructure.
Spreading our Transparent Internet Caching (TIC) infrastructure such that it encompasses mobile internet traffic, we have increased customer satisfaction by moving 18% of our traffic to this closer infrastructure, while cutting annual operational costs.
We have begun infrastructure renewal operations to increase our 3G Network coverage.
The frequency tender held on 26 August gave Turkcell the opportunity to increase its 3G network capacity. With two additional carriers acquired at 2100 MHz, our bandwidth in 3G has increased from 2x20 MHz to 2x30 MHz. We will be able to use these frequencies for other technologies as they evolve going forward.
To increase our 3G network coverage further, we have begun renewal operations at our network infrastructure in order to provide UMTS 900 service.
Our fiber infrastructure has exceeded 35 thousand kilometers.
At the end of 2015, we reached 2.4 million households in 15 cities with our fiber infrastructure. Our fiber infrastructure reached 35,269 kilometers.
This year, the city of Eskişehir was also introduced to Turkcell fiber internet. As Turkcell, we offer 10 times faster than average internet speed in Turkey to our customers in Eskişehir. When complete, we aim to offer fiber broadband to more than 110 thousand households in this city.
Moreover, we continue to connect our base stations to our fiber infrastructure. Thus, we guarantee our continued provision of the fastest and top-quality broadband experience to our customers, and at the same time, ensure that our network is ready for 4.5G.
We have increased our transmission capacity to over 13.5 Tbps.
We have increased the amount of traffic carried on our transmission backbone by 58% year-on-year to 13.5 Tbps. With the expansion and optimization projects in our main backbone to meet the increasing data traffic demand in our mobile and fixed services, and to provide high performance access service to our customers, we have expanded our 10G based transmission infrastructure to 100G based infrastructures and transmitted from Edirne to Şırnak.
With investments in our Carrier Grade NAT (CGN) infrastructure, we have increased our volume of fixed network customers receiving service via CGN by 36%, and have reduced the in-use Public IP ratio from 70% to 57%. Thus, we now use our limited number of IPv4 sources more efficiently.
We have taken important steps toward becoming the leading player both in Turkey and the surrounding region by strengthening our internet infrastructure.
With our total international capacity bandwidth, which we have raised to 2 Tbps by increasing it approximately 500-fold over the past five years, we have undertaken an important role in meeting the increasing demand for internet, particularly in the Middle East, and have supported the entry of new global operators and investors into the Turkish market. At the same time, with our strategic partnerships, we enable operators in the Middle East and Caucasus, and our customers, to quickly reach the largest operators in the world, while maintaining high quality.
Additionally, we create a variety of routes through our business partnerships with Europe’s most important infrastructure and capacity provider operators and contribute to Turkey and countries in the region experiencing “continuous internet”.
On one hand, this continuous increase in the total international bandwidth capacity is of great importance in terms of the contribution it makes to our vision of rendering Turkey a regional internet base and Istanbul an internet capital. And on the other, it encourages content to remain within the country by providing the internet output of major national players and content owners through this high capacity.
With our high traffic, we encourage new global operators and investors to enter the Turkish market and grow the market with the economy that this traffic has created.
We give particular importance to operational sustainability.
With the Terminal Server project, we have made it possible to access devices, access to which is lost via our own network in the event of a disaster. To avoid POPs remaining isolated and to maintain operational sustainability in cases such as multi-fiber or equipment failure, we kicked-off the Terminal Server project as part of Turkcell NDC, Main and Midi POP points to access relative equipment through console interface or current NMS systems through alternative channels (ADSL, 3G) that do not use Turkcell network sources.
NEW PRODUCTS; NEW SOLUTIONS
Full support to the availability of local products!
Turkcell continues to give extensive support to the projects involving local products. We cooperate with local companies regarding base stations, antennas, transport and infrastructure solutions. Since the agreement signed between SSM and Turkcell in March 2014, we have supported the ULAK Project, which is on developing local base stations, with our most experienced Turkcell engineers. In 2015, we contributed to the product development by transferring mobile operations experience and providing a test environment. Turkcell’s goal in this project, which we have stated before, is to contribute to the positioning of 4.5G base station manufactured locally as a competitive product not only in Turkey but also in the region and beyond.
We offer switchboard services to our customers through “Smart Switch”.
In respect of our fixed voice infrastructure being an IMS (IP Multimedia Subsystem), we are able to provide fast communications services in parallel to global trends. At the head of these services is our “Smart Switch” service, launched this year. With this service, we are able to provide switchboard services to our corporate customers through our network without them having to incur investment costs.
We provide the Smart Switch service, which is among our Unified Communications services, to our clients with a mobility feature by enriching it with the soft client service provided on PC & mobile devices.
In the upcoming period, we will continue to rapidly bring new generation services to life with services such as video-conference and WebRTC.
We have developed creative solutions with small cell.
We have prepared product and network infrastructures to provide location based services to our customers with Femto solutions positioned as Small Access Points. Thus, we can inform a 3G subscriber once they enter a Femto service area.
We have completed the installation of agricultural meteorological observation stations.
We handle the TARBİL (Agricultural Tracking and Information System) project together with Istanbul Technical University. This project which aims to increase agricultural productivity and to support farmers’ income, is owned by the Turkish Ministry of Food, Agriculture and Livestock. Our subsidiary Global Tower carries out the installation and maintenance of agricultural meteorological observation stations in agricultural areas as part of the project.
We have built the wireless infrastructure of the Gendarmerie Integrated Communications and Information System.
We are carrying out Aselsan’s “Gendarmerie Integrated Communications and Information System (JEMUS)” project providing possibilities such as voice communication of high quality, the exchange of electronic mail, file sharing, intranet access, safe and fast data transfer, crime and criminal investigations, and so forth, for the Gendarmerie General Command. Moreover, Global Tower conducts wireless infrastructure system installation operations in the Black Sea and Eastern Anatolian regions as part of the project.
Our customers can use “Corporate Wi-Fi” services without incurring equipment investment costs.
We have introduced our “Corporate Wi-Fi” service for wireless internet services that our corporate customers are willing to offer to their own customers. We provide a turn-key service, where their services are managed 24/7 and the regulatory responsibilities are carried out without our corporate customers investing in equipment.
OUR ENVIRONMENTALLY-CONSCIOUS APPROACH
As Turkcell, we became the first telecommunications operator in Turkey to receive the ISO 14064 – Accounting and Verification of Corporate Greenhouse Gas Emissions document.
In 2015, we were awarded ISO 14064 Certification, which is the management standard of voluntary and independent greenhouse gas emissions projects. As Turkcell, we have fulfilled all our responsibilities regarding greenhouse gas emissions standards, and we became the first telecommunications operator in Turkey to receive the ISO 14064 – Accounting and Verification of Corporate Greenhouse Gas Emissions Certification. We are conducting studies into the risks caused by climate change and the new opportunities to be created, and are making these studies part of our strategic plans.
We are reducing our carbon footprint with energy efficiency initiatives.
With the new generation energy efficient equipment and energy saving implementation in our network, we are continuing to invest in reducing our carbon footprint. Key actions taken in this regard and the amount of energy saved were as follows:
- 43,700,000 kilowatt-hours per year from inverter type air conditioners at 18,222 sites with high energy efficiency preferences in product selection,
- 13,150,000 kilowatt-hours from high efficiency power supplies in 10,311 sites,
- 7,313,000 kilowatt-hours per year from passive cooling systems in 11,348 sites,
- 400,000 kilowatt-hours per year from locally manufactured outdoor cabinets in 700 sites,
- 3,000,000 kilowatt-hours per year through optimizing the number of power source modules,
- 6,000,000 kilowatt-hours per year from equipment modernizations in 1,707 sites in 2015 alone,
- 355,000 kilowatt-hours per year through the use of renewable energy systems,
- 1,300,000 kilowatt-hours per year with improvement works made in the energy infrastructures of buildings,
- 5,000,000 kilowatt-hours per year with the revision works of buildings’ lighting and mechanical systems.
Thus, we have saved as much energy as the annual energy consumption of 29,700 households by consuming approximately 80,218,000 kilowatt-hours less within a year.
