Communication – Privacy and Intelligence

Assistant Professor Doctor Serkan AYDIN

 

Communication privacy was violated and intelligence roams around. These situations caused chaos and this oppresses the world.  Although, the expression of “Attention! The enemy listens.” sounds strange at first sight, the essence of the matter, when telecommunication access is done, the information should be transferred of set purpose of its privacy. This decision can be associated with country’s lasting for a state.

If the people who will provide the communication security of the government agencies aren’t investigated, it could cause too big security flaw.

In wired communication, main backbones are made real with fiber-optic cables. Important data flows in fiber-optic cable. The biggest weakness of fiber communication occurs because of it has too much information. The light in fiber-cables can transfer and copy to another fiber hair by so basic and inactive operation. The same information can be increased after this operation that is done by optic splitters. The next operation is saving the information in the same speed and creating the original information by processing the information packs. Ciphered information works for intelligence officer. Ciphering process serves for the real-time communication.

Storing the data in the satellite communications can be carried out without any excavation or termination. Now even PC-based receivers with the mac address of the person who downloaded the data from the satellite to the program will communicate over the Internet. How about if you own a site that can be viewed when you surf the Internet. The same situation also applies in GSM and Wi-Fi wireless communication environment is realized.

The law came into force as part of the privacy and freedom of communication. Internet service provider, many can easily control the content of the information they provide. IP-based services can be estimated that the needs of users in these systems. Simple and complex data mining processes can be applied at the site of entry making them appropriate ads.

This process can’t be made in the satellite TV broadcasting. But this may be different in the Internet support the receiver. It is clear that users who allow the purchase advertisement will pay less than other users.

The severity of contact with the work carried out in the state privacy is important. In this context, privacy and freedom of communication with the world and in Turkey, restructuring must take place. As soon as the cold war, must disappear the evidence and peaceful future work should be done.

The total amount of exports of our members has reached the level of four hundred million USD in 2012. We are the leading  producer of dish antenna   of   Europe . Our annual capacity is more than ten million satellite receiver sets. supports the visual order in the standarts of  use of satellite antennas not only  in our  country but also all over the world and carries out studies in this field . It aims at  making  the models of use of  satellite antenna applied in the modern cities into a visual standart.

Not only  Tv Satellite systems but also IP Tv and Satellite   internet systems are among the leading  subjects of the corporate members of TUYAD  association .  The new generation KA Band Satellite internet systems are offered as an alternative to fiber optic internet systems and are sought for  as such.

Watching TV  and having internet communication through  satellite antennas also supports having  more free and lasting systems. In our  country,  cabled broadcasting and communication of information is not an alternative to satellite antenna in terms of technical capacity and efficiency but only  an alternative offered to the preference of the audience like the land-based digital system.

Television  watching alternatives in our  country are satellite antenna, local antenna, digital platforms and cable Tv

According to the data for the year 2012;

Out of  19 million Tv watching points, the number of satellite antenne subscribers, cable Television subscribers and digital platform members are 12.3, 1.6 and 4.7 million respectively while the remaining audience prefer local antennes.

The majority of the audience prefers satellite antenne as the  figures above show.

The number of buyers of satellite antennas sold in Turkey in 2012 has been 3,816.000 pieces. 1.542.000 of these antennes have been sold  with the purpose of transition to new HD technology .

It is anticipated that the number of digital and/or high- definition  channels transmitted through the satellite shall increase and the  satellite antenna shall be prefered more as soon as Türksat  4A and 4B satellites go live.

Land-based digital/ numerical broadcasting and its future

DVB-T2 broadcasting shall  commence in 2013. Land-based digital DVB –T2 shall be applied through MPEG 4 system . Analogue broadcasting shall be totally closed in 2015 and the land-based  broadcasting shall only  continue digitally.

We are the holder of  success award for exports of Turkey with our 40 corporate members. Many european   countries, Russia and  middle-eastern countries prefer turkish  brands for their quality and logistical   advantage.

Ka Band Satellite Internet – Muhammed Halil Şahiner / Martin Telekom AŞ

 

Nowadays, rising generation communication and need demands of all consumers from individual users to corporate companies increase the need of wideband internet usage. After the developing of communication infrastructure, these needs are tried to satisfy by wireless communication organs like Fiber Optic, 3G/4G and Wi-Fi. Although these kinds of communication infrastructures are in many places, the satellite communication is an alternative come to mind in the places that don’t have enough substructure or need in high quantity of investment for setup cost.

 

Increase in wideband communication needs depending on developing technology and high costs and expensive equipment in Ku and C band substructures promote people to use Ka band satellite systems. Under favour of Ka Band satellite technology, wideband communication services are able to offer high speed and low equipment.  The same frequencies could service to users from satellite footprint. By this means, it happened possible to reach higher satellite capacities and as a consequence of this, Ka band internet access prices became to be able to compete with terrestrial wideband services. Also, instead of involving a wide area as in Ku and C band satellites, as a result of smaller coverage area and high frequency (26,5-40 GHz)  Ka band end user antennas could be small sizes.

 

Ka band services are using especially in geopraphies that has inadequate communicate substructure such as Middle East, Africa and South Asia. First of all, it is possible to organize areas of usage,

 

  • Wideband internet services
  • VoIP, RoIP
  • E-education
  • Broadcast services
  • Institutional applications
  • Mining and Petroleum Institute
  • Tele-Health Services

 

In this article, we’ll dwell on the embedded communication solutions that help to increase usage prevalence and integrated work with Ka band solutions.

 

Embedded Communication Solutions Integrated with Ka Band Satellite Internet

 

To request to send HD live broadcast in publishing area, to provide economic IP communication in the places unfavorable substructure, GSM coverage zone in the places doesn’t have any GSM coverage zone make Ka band usage service in wide area.

 

Modeo Encoder

 

Nowadays, HD video usage became pretty popular. For HD video broadcast by Ku band satellites, more satellite capacity and big and expensive equipment usage are needed. To transfer these HD scenes by way of Ka band satellites, the devices able to fit the bill are needed. For HD video broadcast with sharing internet services proffered by Ka band satellite operators, dynamic Encoder that different from standard ones and suitable to work for band wide is must. Our group firm CTECH saw this need and developed home production Modeo Encoder. 2 key features that Modeo Encoder has are,

 

  1. Adoptable Bitrate Algorithm
  2. Bonding Algorithm

 

The content is coded with more than one bit rates and the video stream is made over the Internet by ‘Adoptable Bitrate Algorithm’ developed for Ka band Internet services.  Modeo Encoder decides the most suitable video bit rate and perceives the upload rate and satellite delay. Through, it became possible to video transmission suitable for changing satellite band wide and delay in satellite. In case of more than one upload capacity needed to send HD video content, it is possible to compound Modeo Encoder and Bonding Algorithm of different satellite modems’ capacities and reach higher speeds.

 

VoIP

 

Our group firm ClickNET that bring Ka band Internet services into use in many countries based on the agreement with global satellite operators serves VoIP service with Ka band Internet access. Without needed any extra investment with IP phones, making telephone conversations, over IP protocol are possible. By this means, making cheap and free- location telephone conversations over Ka Band Satellite Internet Service is possible.

 

The attention should be paid in some points of VoIP applications over internet. One of them is current band wideness. Ka band internet services meet the different band widths needs for VoIP.  Second point is delay period.  Recommended delay period by ITU is 400 milliseconds. This time is less than requisite time of 500 milliseconds for transmission of satellite signal between earth station and satellite but there is no problem in this implementation. Another topic is package losses. The operating logic of VoIP is delicate internet connectivity. There are lots of factors in satellite communication that affect satellite signal. That’s why, BER value (Bit Error Rate) need to be pretty low, initially. For warrant VoIP traffic transmission, QoS and prioritization should be done. There are various developed coding algorithms and the most common one is G.729 Codec. 8 kbps capacity is needed for G.729 coding. Other current standard is G.723 and for this, 5.3 kbps is needed.

 

RoIP

 

Another service we offer as ClickNET with Ka Band Satellite Services is RoIP (Radio Over IP) solution. Due to this solution, analogue transceiver systems (VHF, UHF) could be work with internet networks. At the present time, the availability to usage of commonly used analogue transceiver systems over Ka Band Satellite Systems offers economic advantages to answer the communication needs. On the system coattails, an integrated solution with other systems like VoIP etc. over IP is provided.

 

The studies about making other communication systems able to work over Ka Band Satellite Systems are done and tests are ended up successfully. We could count the systems that provide GSM communication carry over IP like FemtoCell and GoIP between them.

 

Integrated solutions are provided by Ka Band Satellite Systems enrich the current communication technologies. Various more quality and economic solutions are provided by this technologic wealth will continue to increase quality of life of humanity.

The Digital Broadcasting Transition Period of Terrestrial TV and Radio

 

 

Radio and TV channels are categorized as terrestrial, cable, satellite and Internet publications according to their transmission medium. In our country, satellite and cable publications are licensed by Radio and Television Supreme Council Corporation. Terrestrial publications broadcast as part of Radio and Television codes. Terrestrial publication establishments’ number is below by July.

 

Table 1: Applicant Institutions to Terrestrial Analog TV Publication

 

3984 numbered Radio and Television Institutions and Publications code entered in force in 1994 and sentenced to make frequency plans and then license publication institutions.

 

In an attempt to assign channel/frequency for terrestrial broadcast to Supreme Broadcast broadcasting organizations, we went to tender for 3 times in 1997, 2001 and 2013 but licensing operations were not completed for a variety of reasons. Because of this, sorting tender of licensing terrestrial radio and television broadcast weren’t put in, code 3984’s ad interim 6st clause continues.

 

Within the rule of today’s technology and legal acquis AB, as a result of regulations of AB Audiovisual Media Services Instruction that entered in a force in 2007 December by broadcasting in AB Gazette, 6112 numbered code about Radio and Televisions’ Establishment and Broadcast Services entered in a force in March 3, 2011.

 

In 2006, Regional Radio Communication Conference (RRC-06) came together within International Telecommunication Union (ITU) in Cenevre.

 

Table 2: The allocations are made for Turkey in RRC-06 Conference

 

Figure 1: Turkey Frequency Areas Determined in RRC-06 Conference

 

  • TV channel and radio frequency planning will be made by Radio and Television Supreme Board, national, regional and local territorial broadcasts’ numbers and types and multiplex numbers will determine for numerical broadcasts.
  • 6112 numbered code’s release date is March 3, 2011. From this date, within 2 years latest, numerical television multiplex capacity sorting tender will put in.
  • At the end of this 2 years, analog terrestrial television broadcasts will be finished countrywide and analog terrestrial television broadcasts will be stopped.

 

In this context, on the date of April 16-18, 2013, National Terrestrial Numerical TV Broadcast License Sorting Tender; on the date of May 2-3, 2013, Regional Terrestrial Numerical TV Broadcast License Sorting Tender; on the date of Jun 24-28, 2013 and July 01-02, 2013, Local (T3) Terrestrial Numerical TV Broadcast License Sorting Tender were performed and tender results were published in RTUK Internet website. Aforesaid tenders were confirmed by Supreme Board.

 

 

But, national tenders’ executive was stopped in the direction of court decisions about aforesaid tenders and then were cancelled.

 

Turkey’s terrestrial numerical broadcast standard was determined as DVB-T2 and MPEG-4 that is the last technology in numerical publishing and accordingly, Terrestrial Numerical Television (DVB-T2) Frequency Plan was prepared. Later, having regards to developments of compression technique in the world, instead of current MPEG-4, new technology HEVC (High Efficiency Video Coding – H.265) compression technique was defined.

 

For our customs aren’t aggrieved, devices’ necessary specifications were defined and by name of TS 13538 “Television Receivers – General Rules for Second Generation Numerical Terrestrial Broadcast System (DVB-T2)” was accepted and published by TSE (Turkish Standards Institution).

 

As a result, in our country, terrestrial numerical TV broadcast is not used yet. Cancelled sorting tenders make this process be late. Regulations and specifications’ editing works are continued and these works should be completed as soon as possible and sorting tenders need to be done.
