2016 in Review -----Trends in Telecommunications, Media and Technology
Dear Audience, this article is a summary of moments in 2016 from all of us at NGIT, we hope you enjoy it!
However, reality today shows that most of the
telecommunication operators are stuck on
their traditional markets where they are faced with revenue profitability
decline especially in Africa . For
instance in Nigeria, before the new suspended price floor of N0.90k/MB, the
industry average for dominant operators including MTN Nigeria Communications
Limited, EMTS Limited (Etisalat) and Airtel Nigeria Limited was N0.53k/MB.
Etisalat offered (N0.94k/MB), Airtel (N0.52k/MB), MTN (N0.45k/MB) and Globacom
(N0.21k/MB). The smaller operators/ new entrants charge the following: Smile
Communications – N0.84k/MB, Spectranet – N0.58k/MB and NATCOMS (NTEL) –
N0.72k/MB
These Prices were recently debated on for an increase by
NCC for a better data price floor. All in the move to increase revenue
profitability and ROI.
Telecoms are also lagging behind over the top companies
digital command scalabilities. Telecoms of today are highly complex with many
product and service combinations offered through various channels maintaining
various platforms so they cannot move faster. Their cultures are still
technology centric so it is not surprising today that their market capitalization
are much lower than over the top internet companies. What telecoms should do as
we look ahead into the year 2017 which is the opportunity for telecoms is to
digitize. Digitize to define new business model, digitize the delivery model
and embrace the digital culture. First they need to decide are they a
connectivity players offering various connection services to various customers
whether a consumers or residential? Are they a digital enabler offering various
platforms to businesses that connect to end users? Or they are digital life
provider for their customers tapping more into the service part of the market
which is growing today with digitization.
In doing so, telecoms can learn a lot from the over the top
companies especially in the domain of the digital customer experience.
Self-Service capabilities, 24/7 availability of the services all which are
embraced throughout the personalization of the services. Those are the elements
where telecoms can learn better from
over the top companies and be better. Telecoms should be simplified. They
should eliminate non value edit part of their portfolios and they should
simplify their operations. Eliminating services that don’t add value from the
perspective of the customers. They should be developing a set of unique digital
capabilities and they should embrace a culture which is much similar to
successful digital start-ups for today. They should acquire new digital talent
and collaborate internally and they
should transform their culture
In essence, impart for telecoms in the year 2017 as we look
ahead is to Simplify, Digitize and
Consolidate.

Annals of Multimedia Broadcast Multicast services
The objective of this month's article is for our audience who are interested in the Transmission Reliability of Multimedia Broadcast Multicast services and that is why we put
together this article from today's workshop proceedings. 28th October 2016 12.00Hrs G.M.T
NGT systems has a global footprint. We are aware that some of our audience may not have the chance to visit us both in conferences and workshops, If your have specific questions about NGT Multicast and broadcast services and about our products, feel free to stop at our online chat room with one of our representatives and drop us a mail at corporatesales@ngittech.com.ng to tell you more about the company. right now,
The proliferation of
on-line media applications and digital entertainment have contributed to the exponential
growth in Multicast-aware technology. This technology enabler has facilitated
the delivery of best effort Quality of service (QoS) to a group of consumers on
the global network. In recent times, the Internet Content consumers’ Quality
of Experience (QoE) grown from 40%
in 2014 to 80% in 2016 based on Multimedia Broadcast Multicast service
delivery.
A little background on Multimedia Broadcast Multicast services reveals that Multimedia Broadcast Multicast services
is a point- to-multi-point interface specification for existing and upcoming 3GPP cellular networks which is
designed to provide efficient delivery of broadcast and multicast services both
within the cell as well as within the core network. The broadcast transmission
across multiple cells. It defines transmission by a single frequency network configurations.
Target applications includes mobile TV and radio broadcasting as well as file
delivery and emergency alert.
Deployment: MBMS Mobile broadcast
technology has never been deployed by any operator in the world as suppose to
other technology such as DBBH, ATSCMHIH DBTMM. Various mobile technology in the
UK had conducted trials for MBMS based mobile TV. There is no indication that
this trials resulted in any commercial deployment. In 2013, Verizon was the
first operator to anounce the Bolunchi MBMS services.In 2014, over its LTE
Networks. eMBMS is the LTE version of MBMS. AT&T subsequently announce
plans to use the 700MH lower D block licences it acquired in 2011 from qualcomm
for an LTE broadcast service.
In 2014, several major operators
are lining to deploy and test the technology. In July 2014, Nokia networks
demonstrated the use of LTE broadcast to replace broadcast traditional digital
TV. This use-case remains controversial as some study are doubting the
capability of LTE broadcast to address this use-case efficiently in its current
version. In August 2014, ericsson and pokontel successfully tested the LTE
broadcast by streaming the opening game of 2014, world volleyball championship
to hundreds of guest in euro on majesty trademark national stadium in Poland on
August 30th. 2015. Competing technologies of MBMS
include DBTHDMB DBBHBSM and media flow.
However, due to spectrum scarcity
and cost of building new broadcast infrastructure, some of these technologies
may not be viable. Media flow has been deployed in the U.S by Verizon in
relationship with Media flow U.S.A in corporated. However, the service was shut
down in early 2011. DMBMDH trials has been on-going for more than a year now. During the football 2006 championship in
Germany. Always proprietary CMBS is a precursor to the multimedia Broadcast
Multicast service. It was specified in 3gpps 6 using the existing UMTS
infrastructure and real-time streaming protocol.
Technical
Description:
The MBMS feature is split into the MBMS bearer service and the MBMS user
service and it been defined to be offered over both UTRA and LTE. MBMS bearer
services include the multicast and broadcast mode but only the broadcast mode
is available over LTE. MBMS bearer
service uses IP multicast to addresses for the IP flows. The advantage of the MBMS bearer service compared
to unicast bearer services is that the transmission resources in the core and
radio network are shared. 1MBMS packet flows is replicated by GGSN, SGSN and
RSC’s. MBMS may use an advanced counting scheme to decide whether or not Zero,
one or more dedicated radio channel leads to a more efficient systems usage
than one common radio channel. UTRAN MBMS offers up to 256kbits per MBMS bearer
service between 800kbits and 1.7 with scell band. The actual cell band depend
on the UE capability. MBMS offers between 32kbits and128 kbits. Up to 4 GSM
time slot may be used for one MBMS bearer services downlink direction. The
actual data rate of traffic flow depends on network dimensioning.
The MBMS user services basically
the MBMS services Offers adopt the streaming and download delivery method. The
streaming delivery method can be used for continuous transmissions like the
mobile TV services. The download method is intended for euroE download euro services
To increase the transmission
reliability, an application RFC code may be used. MBMS has been standardized in
various methods of 3GGP and the first place standard on UMTS release 6. Release
6 was functionally frozen by the third quarter of 2004 and practical network
implementations may be expected by the also end of 2007 at the best functional
mobile terminal services. EMBMS has been standardized by various groups’ 3GGPs
part of LTE release 9. The LTE version of MBMS referred to as multicast broadcast
singular frequency network support based on FDM wave form and similar to other
broadcast solutions such as DBBH. 3GGP technical specification MBMS bearer service.

Dense Wavelength Division Multiplexing and Optical Networks Fundamentals: Practical recommendations for Deployment.
The objective of this article is meant to be for someone who has not done Optical Networking or Optical Engineering and this is why we put together this article from today's Conference
23 September 2016 15.00Hrs G.M.T
Let get started by asking this question. how many of us reading this article have deployed Optical links or engineered one or have designed optical networks or let re-phrase like this, how many of us have designed or engineered an optical transmission link( SDH/WDM)? or a multiple-node optical transport network? ok! like we said this article was designed for someone who have fairly or no prior knowledge of Optical Networking.
We here you say hmmmm. ok not to worry. now we speak from the provider side or provider services, how many of us are considering to lease a wavelength or multiple wavelengths in the next 6-12 months for providing connectivity? one, two ok Thank! you.
Now in reference to this article with a focus on dark fibre or sometimes called in outer regions as grey fibre. How many of you are considering to lease a dark fibre or wavelength services in upcoming months?, Ok excellent! so ok assuming we have our audience reading this article coming from IP networking background and we will just have to level set for those of you who have not been dealing with optical networking.Most of the time if you are dealing with data networking, the router, MPLS switches, layer 2 and above, usually what you see is a grey cloud, you have the edge device CE, you have the core (P) and the edge core demarcation.(PE).
Typically, this can be across countries so you don't necessarily have to care about the underlying physical infrastructure. All we care about is the logical connectivity between the routers and switches. One often needs to know if the routers have a 10g, 40g, 100gig interfaces and how many of this interfaces are available.But depending on applications obviously, you do care sometimes. This is what we see in textbooks from juniper or Cisco.
For optical networking, however, the physical actual fibre map is an important element for optical link or optical network engineering . So what we see and important in any optical networking design is that we always need to know, how the actual underlying topology is being connected;the fibre distance and fibre characteristics to design an optical networks assuming you are planning for an optical networks, optical links, where there is a ring type topology, where there is a mesh type topology, where there is a point-to-point or point to multi-point. topology. these is always an important consideration.
In optical transmission layer, one needs to know exactly the underlying fibre topology, the fibre details and characteristics so that the optical layer and equipment can be dimensioned accordingly.
So let walk through on how an optical network and link can be designed.
In this article, we will look at this from the physics and physical engineering point of view and also from a networking point-of view so that we can see a bigger picture.
A little bit about our background as well, We are fortunate to and have an opportunity to design all networks in this field for the Tier-1's Whether is in the US, North America, Asia Pacific and now Africa.
Let start from the basics which is a point-to-point and answer some common questions for any optical link/network planning. Since we are dealing with fibre optical networks, the condition of the fibre, the length of the fibre, the characteristics of the fibre are very important information before you start designing any optical engineering network of links. For example, the length, obviously you need to know the distance, is it going to be from rack to rack within a data centre.Is it going to be from data centre to data centre e.g TI tO T2 or E1 TO E2,. i.e the fibre distance or fibre topology map for the design or is it going to be from city to city.
Secondly, how many fibre strands do you have? from the extreme case running to vendors of service provider. The only lease or by-fibre is one strand at a time. We mean not fibre pair but one and they want you to do high capacity transmission over a single fibre stand. A low cost provider will like to do that where the business case justifies it. Do you also get a multiple fibre strands sometimes in cases of North America where the providers are so fibre rich. You have multiple fibre in that case you might not need WDM.Right! because each fibre pair can actually be put 10gig capacity, 100 gig capacity and that might be enough where dark fibre is so cheap or so abundant between some locations, countries or some cities.
So after you have understand the connectivity from this point to that point. How many fibre can you get, lease, rent, borrow?
Thirdly is the type of fibre string. Obviously, if you talk about metro, regional or long haul meaning spanning a hundred or thousand of kilometres.In all the cases, it is likely to be single-mode fibre.This is the type of fibre used for long distance transmision whereas multi-mode fibre is more like cross shelf between rack types. Also there are multiple fibre types as well(SMF). standard common fibre (SMF) types are G652 (SMF-28) G653(DSF) G655(NZDSF). In japan, there are some fibres using G653 which are quite very challenging in the way you design that link.There are some techniques which you can use with seebeck equipment over DSF fibre depending on the distance and the condition of the fibre
e.g coning'S SMF-28 is commonly used in todays networks.
Fourthly, the condition of the fibre strand meaning do the strands have a lot of knots in it, connections, a lot of space, air space due to eigen or microbend factor. This affect the overall loss between point A to point B. Why do we care about high loss fibre? This is because the loss is directly proportional to amplifier in the link ie. amplifiers might be required if the fibre loss is very high therefore you will have to buy more equipment to transmit from point A to Point B if the loss is too high. Also the age of the fibre. is it underground or area fibre. These are all very important as it poses varying challenges because the design for a fibre in japan is different from India and Illinois, Chicago. Also germane is the number of splices or connections on the fibre.
Lastly, is your expectation on the bandwidth that you will transport over this fibre link meaning the End of Life (EOL)transmission capacity. This answers the question, how big should "the pipe" be? Do you need 10Gb/s? 40Gb/s or 100 Gb/s or multiple 100Gb/s per wavelength. How many wavelength(s) or "highway lanes" do you need. The End of Life means the life cycle of the network. what is your expectation? right!depending on the capacity you need. Vendors like NGT or whoever will have to design the network accordingly by picking different level blocks to put together the design for you. You want an optimized for the first course, that one approach or optimize for flexibility, that another approach .
For us we deal with the spectrum of customers to the single fibre strand.
The Only one may be HL of 10Gig or NGT want 96 channel 100gig? they won. No questions to ask. we know how to use the capacity. we know that we will grow with that, infact you have to tell us if this platform can upgrade to 200 per wavelength as well. so we have a whole spectrum of requirement. This is very important.
Today as at the writing of this article, we can clearly inform you that terabit link capacity is not uncommon to connect data centres in metro networks e,g in tokyo, japan , hong kong etc. Customers directly buy say give us 500gig between these two point or give us 600gig between theses two points.Very very not uncommon, in order words it very common especially in the datacentre interconnections (DCI)
One of the key thing about fibre is attenuation or loss measured in decibels. As we have the fibre relaunch from point A to point B, the power coming from the laser will reduce due to the scaling of the light and due to the loss when we travel a distance. So depending on the condition of the fibre, depending on the length, typical fibre loss could be 0.20dB/km - 0.35dB/km. although in some regions fibre loss may be as high as 0.5dB/km. It may be the dark fibre, ageing or all of the connectors.so when we average the loss over the length , 0.5 dB/km to 0.6dB/Km can be obtainable.
From the link perspective,The number one basic link budget engineering are fibre loss, spice loss,connector loss and safety margin. This should be far less that power budjet. When we launch at power level from point A to Point B to a lower level by transmitting and receiving power over the fibre link we get loss, after all most of the optical networks last for 5, 10 or 15 years.
On top of that is another concept to know which is the concept of transmission window. e.g for 800 ,1310 and 1550 wavelength in manometer(nm). This is referred to the band of the transmission window and each transmission window obviously has different profile because of the fibre.

SDN FOR OPTICAL TRANSPORT NETWORK SERVICES
By Kenny Ade: 30th July 2016 @ 24.00Hrs
There have been so much discussions and so much marketing with Software-Defined Network.
It is important in this article to enumerate the problems that we are trying to solve.
SDN is really interesting for four major issues in the network. The first is efficiency. Right now when carriers operate different transport and packet network, they tend to experience strands between these two layers which result in excess cost.ie ( transport and packet bandwidth builds excess cost into carrier networks).
The second is cost by using better multi-layer planning and provisioning. The objective is perhaps, some of the higher cost equipment specifically layer 3 routers as well as O/E/O convergence can be reduced in sending traffics to ROADMS or expressing it pass router. The third is flexibility as this is most important benefit of SDN and that is really taking the network asset and making them more responsive not just to your own internal operation but ideally to a direct customer control and finally the fourth problem is potentially to solve disaggregation. This will allow service provider to reduce dependence on a single vendor within a domain and if we take this to its ultimate conclusion, you could dissagregate network right down to specific points.
The key take here is that SDN is really about automation and not central planning. It about using automation tools to extract more value from the network.
One of the catalyst that is really triggering service providers to look at deploying SDN is the transition of packet capability moving down to transport layer.
As we go from now till 2017, there is a significant increase in amount of traffic that service provider are expecting to handle using packet optical equipment. There is a decline in the use of layer 3 dedicated routers so optical equipment will play a larger role in providing packet switching and aggregation by 2016. Routers are not going away. Packet optical is still secondary to routing layer. The decrease in the deployment of this technology is really catalyzing SDN in the transport layer.
Optimally, a management approach that balances the use of one layer versus the other is needed.
Bottom-Line, SDN is really just an enhancement of traditional routing models.
At the end of last year, Infinera really surpass report on the Carrier SDN market by estimating direct spending on software market size including NFV orchestration and controllers. This year estimate is pretty small around 200 million dollars and forecast a growth of about US$1.2 Billion Market by 2018.
Also worth mentioning, how service providers are changing operations in order to use SDN.
In respect to flexibility and automation in our discussions with service providers, there is a rise of dynamic cloud services driving the need of routers to increase speed of innovation and support faster service creation, they need to move faster transforming into a DevOps model and deployment while lowering costs.
The DevOps new model is a model that breaks down silos between development, QA and Operations to rapidly release new services and service enhancements as new features become available.
The traditional Telco Model is slow, rigid with siloed product development cycle as different teams specify and develop software, while another do software testing , integration and test before deployment and this could take up to 18-24 months to deploy. DevOps IT Model is a scenario where you combine the development team, the Q/A team and Agile & collaborate and quickly release features as they become available. What this allows the carrier team to do is move much more quickly in terms of service creation and get your new services out of the door and much more customize to what the users need.
There are basically two drivers for network renovation with SDN technology. The first driver is information and communication technology (ICT) full-service operation. what this means is that the boundary between ICT and CT has been blurred in the recent years, we have seen the presence of voice and data and on top of that we have seen new applications driven by cloud computing, Smart education, Big Data, Smart Home and M2M and the recent 2K/4K video etc.
Basically, this new applications have really push for the need of application-aware on transport network services providing different OS and TOE upon application.
The second driver for network renovation is the user behavior change faithful to consumer or transport network services.
In the past, the large bandwidth will establish static connectivity asking a major consumer transport network. This is changing as user application now require much more that end-to-end agile services based on the premise of pay for usage (PoU). In a nutshell, the transport network have to provide faster and smart services that is needed for user experience.
We have been able to identify what is happening on the transport networks. In this article, we focus on the Transport SDN problem statement, implementation and solutions as experienced by various service provider deployments and carriers' . We discussed the recommended approach in providing solutions to this panacea

Communication and Networking Technology For Low Carbon Smart Grid
Telecommunication have always played a vital role in the management of the modern grid system. Until the advent of the smart grid, this has been required to deliver connectivity for back office systems and remote monitoring. Information Flow, Data Management, Monitoring & Control at domestic level have been facilitated by information and communication technologies.
The demands of climate change and the 21st century information based society requires the development of a smart grid which is created on advanced communication and networking technologies with frameworks that deliver centralized real time monitoring and measurement control across the entire power grid system. The concept of Smart Grid is the combination of Power grid with the communication technology. A smart grid is an electrical grid which includes a variety of operational and energy measures including smart meters, smart appliances, renewable energy resources, and energy efficiency resources. Electronic power conditioning and control of the production and distribution of electricity are important aspects of the smart grid. Roll-out of smart grid technology also implies a fundamental re-engineering of the electricity services industry, although typical usage of the term is focused on the technical infrastructure.
All smart grid strategies and visions are founded upon the availability of telecommunication network capability. The Energy efficiency and carbon footprint reduction among other leading information and communications technology solutions, radical new power systems architectures and innovative market mechanisms to support increasing renewable energy deployment and the electrification of transportation and heating in the world today are cutting across business and industrial sectors. It is widely agreed that products and services of information and communication technology (ICTF FPNSG) industry are significant enablers for reaching the desired sustainability.
