VoIP business worldwide from Then and Now

VoIP was invented in Israel(1995) by a company called VocalTec. The insufficient availability of telephone and high cost lead to the foundation of VoIP. 

Today, VoIP worth more than 100 billion $ worldwide.

After 3 years of invention, in 1998 VoIP calls account for less than 1% of total calls and in 2000, it accounts for 3% of total calls. By 2003, there were total 7 Billion $ revenue from VoIP. The telecom operators were struggling and thus the charge for calls were almost half. 

The early days of VoIP began with the international long distance communication. The cheaper rate was the main concern over its development. This effect was seen on the telecom operators. The operators began to sustain by purchasing the VoIP from International Exchange Carriers and deployed it by offering at a cheaper rate.

In 2005, VoIP vendor, iBasis alone transacted around 7.7 Billion voip minutes. Skype , a global internet VoIP service provider, has gained over 75 million on-line subscribers in just over two and a half years, after its launch in 2003.

When VoIP took aggressive market, telecom providing POTS where loosing $10 Billion per year from 2001.

In  2000, US company AT&T , Verizona also deployed the system which are capable of supporting VoIP service.  

In June 2004, Vonage, broadband service provider, say the average American phone bill is $72 a month, but vonage provides unlimited calls throughout the United States and Canada for $34.99 a month.
Telecom operators were fighting to keep their customer from cable companies.

By April 2004, Skype has 10 Million users.

In the same year, a research firm says, nearly 62% of North American  businesses , have already switched to internet telephony, either entirely or in part.

By 2010,the fixed line telecom revenue may fall by 25% due to VoIP. Mean while the mobile operators loose revenue by 80%.

However, there were no Emergency call facility in VoIP. FCC takes a bold steps, saying all vendors should provide this service. At the same, VoIP was on track to exceeded $1 Billion in revenue with over 3 Million users.

According to Future Market Insights, In 2012, the corporate consumer VoIP market registered 98.9 billion subscriber, accounting for US$43.27 billion in global revenue.
It also forecast an increase to around 204.8 billion corporate consumer by 2020, accounting for US $86.20 billion in global revenue.
There are about 688 businesses in VoIP industry.

VOIP from then and now | VOIP history

What is voip?

VOIP is the real time transmission of voice over internet protocol. The fundamental of voip is the telephone and the internet. Telephone is used to send our real time voice via local exchange. Exchange is the place where the routing and switching is done of large subscribers. Now after internet was invented, our voice now can be sent via an internet instead of exchange. Voice now will be converted into packets. Packets are the small group of information. Such way of sending our voice/videos is the VOIP.

The invention of PSTN and  internet lead the foundation of VOIP. The telephone was invented by Alexander Gram Bell in 1870's. After the first invention, in 1878, first exchange was established in new Haven, USA. In 1889, hte "strowger switch" was invented which connects one line to any of 100 lines using relays and sliders. Thus was used for almost next 50 years.

On the other side, during mid 1900's, the transistor was invented. Dr Shannon published ,"A mathematical theory of communication" which promoted the concept of communicating in binary code. This lead the foundation for the modern digital communication.
In 1963, US company AT&T created"Touch Tone Dialing". This replaced the human operators because of its automated menus and functionality. This allowed the calls to be switched digitally. 

Mean while, in the year 1968 , Internet was first developed by ARPANET(Advanced Research Project Agency Network ) in USA. In 1989, HTTP was developed in Geneva Switzerland. This formed the basic invention in world wide web(WWW).

Although the telephone and internet were vital to existence of voip, there was another technology that is closely related. In 1972, Vint Cerf and Robert Elliot Kahn invented transmission control protocol/internet protocol(TCP/IP).

VOIP started in February of 1995 by a small company in Israel called Vocaltec. Their product internet phone, allowed one user to call another user via their computers, a microphone and a set of speakers. This would worked for both PC having same software.

In the year 1996, voice mail applications came to life. users can send voice mail over the internet to the phone. However, poor sound quality, loss of connections, etc were major drawbacks.

In 1998, vocaltec went to create computer to telephone and telephone to telephone calling capacity for voip. voip calls accounted for less than 1% in 1998 because of the advertisement that they need to listen before and after the voice call. However, this accounts for 3% of all voice calls in 2000.

Growth and Popularity: 

Different companies pioneered in voip switching. By 2003, VOIP calls account for 25% of all voice calls. The availability of broadband internet services leads to this major leapfrog.

In around 2000, different instant messaging software like MSN messenger, yahoo chat was released. In 2003, skype launch its beta software that it allowed people to make computer voice calls, instant messaging with making voip a full utilization. Soon skype was used to make calls on landline and phones but at a cheaper rate then other VOIP companies. In 2005, Skype introduced video chat into their software, which makes them no one company in the market.
In 2006, yahoo also started providing voice calls between computers. In the same year, microsoft also releases beta of windows live messenger that offer PC to PC, PC to Phone calling service called windows live. In the year, 2012 VIber provide free HD voice calls between applications. Facebook messenger , whatsapp , Line are other application that widely use voip for calls.

The rising market of voip in the year 2014 have been seen in the telecom operators after they provide VoLTE service. It is voice over LTE. Now the smartphones supporting VoLTE can easily send their voice by breaking into packets through the network. As of January 2017, 55 countries have over 102 operators providing VoLTE service. 

VOIP: Voice over Internet Protocol
LTE: Long Term Evolution
PC: Personal COmpyter
HTTP: Hyper Text Transfer Protocol

VoLTE | Difference between VoLTE & LTE | Rise of VoLTE

VoLTE | Difference of VoLTE & LTE | Rise of VoLTE

In this post,  we are going to cover major topic but not limited to:
1. What is VoLTE stand for?
2. Brief Introduction of LTE and VoIP
3. Difference between VoLTE and LTE?
4. Advantages of VoLTE | Rise of VoLTE

VoLTE stands for Voice over Long-Term Evolution. In order to master the VoLTE we need to know major two terms LTE and VoIP. I will explain briefly on these two topics:

LTE: It's acronym is Long-Term Evolution. It is also called as 4G. However, as defined by ITU- International Telecommunication Union, 4G must have at least 100 Megabits per second on peak speed which means that when we are in moving vehicle or train.  when we are stationary, there must be around 1Gigabits per second. But this was not much possible as there is undergoing research. 
So the substantial improvement  in 3G lead on a point such that they can be classified as 4G and thus named as LTE. LTE sole purpose is to solve the rampant increase in demand of data with using existing technology. 

VoIP: It is the technology, that will transmit the voice using IP or packets without using conventional circuit switched technology. Details of VoIP is here.

    
Since, LTE is truely IP based i.e it only supports packet switching with its all IP network.  This is good when we are using data service, but what will happen if call is initiated or received??
So for this problems, LTE have 3 different options:
1. VoLTE
2. Circuit switched fallback: In this method, when call is initiated or received, the Control signal and Traffic signal switched over to 3G or 2G providing  the circuit switched transmission of voice. 
3. Simultaneous Voice and LTE (SVLTE):In this method, the mobile handset use both LTE for data service  and Circuit switched for voice transceiver. 




Rise of VoLTE:

Due to circuit switched fallback, there is substantial decrease in voice quality since, for every time the call is made and received , the connectivity of LTE gets disconnected and switched to 3G/2G. This delay between switching ,which result is cal drop, poor voice quality, cross talk,etc. Also LTE was previously developed only to improve the data service but wasn't careful on Voice.  So to incorporate this problems of voice call, there have been developed of VoLTE. 

VoLTE is just a software (OS)which will be installed in the UE(user equipment) and the LTE network. Since LTE network is a hardware whereas VoLTE is a software. So now ,when the call is initiated, the voice will transmit over IP or data service instead of circuit switched technology. That means our phone now will not use the voice channel but will use the packet or data service channel in the form of Packet. This enables the use of higher bandwidth for voice transmission and thus there will be superior quality of voice.

So using VoLTE in LTE network provides the transmission of voice in the form of packets or IP over data service. There are many handsets that supports the VoLTE and many carriers which are implementing the VoLTE technology. 

As of 2017  January , the total operator deploying VoLTE has reached 40, over their LTE network.

Many handsets are available which supports VoLTE.




Remote Radio Unit | RRU Functions | Details

Remote Radio Unit | RRU Functions | Details 


This whole blog article is being shifted to RRU-Remote Radio Unit Functions. Dear All, we will now post new article in this website named www.telecomkhabar.com . Please use this website and suggest me so I can give you a good concept and knowledge. 
Thank you for supporting me for last 4 years.



Topics Covering:
a) RRU Definition and Overview 
b) RRU Functions
c) RRU Hardware Description & many more

Radio Remote Unit(RRU) is the distributed and integrated frequency unit that connects to an operators network with the User Equipment's (UE's) like Cell Phone and mobile devices.


Fig: RRU mounting in tower

The logical term "distributed and integrated"  is because traditionally the radio architecture for cellular system is based on a single-standalone system(Base Stations) usually installed indoor but now, the cellular architecture is divided.
So now the BTS(Base Transceiver Station) is the integration of various radio unit like BBU and RRU. Despite installing only in indoor , radio units are now installed in the tower below the Antenna.

The RRU is connected to the base station via the fiber optic link which is bi-directional link. The optical interface link is also known as CPRI (Common Public Radio Interface). CPRI is a interface protocol developed by combination of major telecom equipment's manufacturing company.
The RRU helps to reduce the coaxial feed line losses, increase system efficiency  and provide high level of flexibility in cellular site construction. Undoubtedly, this helps in upgrading to new equipment's and devices more easily.

RRU Functions: 

I have jotted down the RRU functions here.


1) Acts as a transceiver: transmit and receive the user signals to the base station and vice-versa.
2) Provides back to back support and connectivity between user equipment's like power, delay,etc.
3) Control and process the EM signals received from the Antenna via Jumper(Hollow Guide).
4) Provide interface between two physical  link: Optical and EM(Electromagnetic).
5) Provide Controlling support of the Auxiliary equipment's like  RCU (Remote Control Unit) for electrical tilt adjustment generally known as RET(Remote Electrical Tilt).
6) Generate and sends the different signals like   VSWR, RET, ACT,etc. 


RRU Hardware Description:

Fig: Port Showing for connection in Huawei RRU
RRU consist of different ports for different purposes. I have summarize the ports that are common among various companies like Huawei, ZTE, Ericsson, Alcatel-Lucent, Orange,etc.

1) CPRI Port:  There is 2 port generally named as CPRI0 and CPRI1. However there may be 1's in some model. The name at suffix may vary. Its function is to connect to BBU.

2) RF Port: We say it as a Jumper port. The number of jumper port may vary with model and company's architecture. At least there is 2 jumper port, one of which is for Tx and another for Tx/Rx. The RF port is connected to the Antenna via Jumper Cable. 

3) RET Port: There is at least one RET port for connection to RCU. The connector is mostly DB9 in Huawei and may vary with other company's. RCU is connected to the Antenna. RET cable connects the RCU and RRU.

4) Power Supply Port: There is one port for powering the RRU. Mostly blue and black. Blue is for negative (-) and black is for zero(0). Generally all RRU operates in -48V.

5) Ground Port: There is two OT port for the grounding. The ground cable: mostly copper wire, one end is connected to RRU and another end into Bus Bar near by RRU. Thus it provides the surge and high voltage protection of RRU and thus keeping safe from natural weather and climates. 



White Space Radio|Next Generation Communication


White Space Radio|Next Generation Communication 

"Everything you need to know about White Space"


"White  Space" refers to the unused broadcasting frequencies. According to Center for white space communicatonwhite space is termed as-"parts of the radio spectrum that are not utilized all of the time or in all geographical locations". 

Since,there are many frequencies which are divided into different spectrum by international and national authority for different purposes. So among those frequency also, there is frequency gap maintained to mitigate the interference among the divided frequency- which is called guard band or guard frequency.

Beside, guard frequency; the switch-over of analog TV to Digital TV have leftover unused many frequency. Since, digital transmission broadcast many signals by compressing in parallel which on conclusion left unused frequency. So such frequency is termed as white space. And the technology is termed as white space technology.

To use such white space frequency, special devices known as White space devices(WSD) have to be used. The WSD have to be present to both sides. The WSD are designed to detect the presence of existing but unused areas of frequency and utilize these unused frequency for internet connectivity or other broadcasting purpose. Currently the WSD are manufactured by Adaptrum, Carlson wireless, Redline communications,etc.

Tech company like Microsoft, Google, Nokia, BBC too have been keen motivated in upgrading of White space radio. They have been doing research in different university and lab of different country. United states, United kingdom, Canada have been doing trail in various states. 
In July 2013, West Virginia University became the first university in the United States to use vacant broadcast TV channels to provide the campus and nearby areas with wireless broadband internet service. 

There is much more potential in developing countries and in rural areas. Developing countries yet have not access to internet connectivity to school and houses. 
The cell tower once established can serve upto 10 km in distance so this helps in point to point connectivity for long distance. 

Kenya, South Africa, Namibia are the countries where there have been use of white space to deliver the internet connectivity in rural areas and schools. Soon other developing countries of Africa and Asia will be adopting this White Space radio. India on making "Digital India" will make better utilize of this radio.



The History of VoIP, which you must know

VoIP History 

VoIP is the fastest growing technology. Where did all this technology came from and how it is developed? Lets go back into time and find out all this things. But before this, If you are unknown about the VoIP and its working process, simply click the highlighted text.


  
Pic: Analog Switching system for PSTN during 1960

In 1973, Motorola made the first phone call using cellular technology to Bell Labs. Now after the cellular technology, VOIP story actually started in the summer of 1974, when the ARPANET(Advanced Research Projects Agency)  sent a 16 kb/s real time voice sample between computers based at the information Sciences Institute and the Lincoln lab, United States. 

In the preceding year, there was no much more influence and growth of broadband Internet, So this has been the major influence in the VoIP. But in back 1995, the Vocaltec, software company achieved the initial success with Internet phone and delivering VoIP software application. This have been the breakthrough in the growing of voice over IP.  

In 1998, in USA alone , 1% of all calls was done through VoIP. By 2000, this percent have been increased to 3%.  

In the later years, with the surplus increase in broadband connectivity , VoIP market have been rampant increase.  In 2004, VoIP telephony had begun with the introduction of VoIP calling plans, which is similar to telephone company and using PSTN. Very low rate, offer and discount have heavily increase the market of VoIP. But with increasing VoIP services, many telecom operators have been been faced  loss in millions of dollars monthly due to call bypass and terminating the call without the use of operator gateway. So some country, still have set the VoIP illegal.


What is VoIP and How VoIP works

In this Post, we will discuss in-depth knowledge regarding VoIP and will cover  major topic which includes:

1. What is VoIP and how it works?
3. What is VoIP phone system?
4. VoIP business 
5. How VoIP is challenging the telecom operators around the               world?
6. Technology used in VoIP service 
7. Many more including how to set up VoIP by yourself

What is VoIP ?

VoIP stands for Voice over Internet Protocol. It is used to send our voice signals via internet communication method instead of local telephone company. VoIP technology involves sending of analog signals(our talks) by converting into digital discrete signals and transmit the discrete signals in the form of packet data via internet. One of the widely used VoIP example is Skype, Viber, etc. 

How it works different from mobile phone and PSTN ?

In PSTN, our voice is transmitted over copper wire as an analog signals between frequency 0-4KHz. In modern cell phone, the cell phone converts our voice into an electrical signals, which is then transmitted as radio waves with using different modulation technique to secure our privacy. 

But in case of VoIP, the voice signals is converted into packet data, i.e  the voice signals are break down and is changed into the packet data. For this various codec method is used.The packet size is defines by the voice over ip packet structure. For example , if size is 4Kb then we can roughly conclude that our voice signals is converted into 4Kb packet size and send over internet time and again. This process is very fast, which is just a work of fraction of second and we cannot even notice it. 
Now in the other end, the packet data is now decrypted. And the packet data is converted to the standard audio signal. Thus communication is established.

Don't miss the history of VoIP.


4G in Nepal!!! Is really a 4G or LTE??? It’s Scope and Hurdles…

4G in Nepal!!! Is really a 4G or LTE??? It’s Scope and Hurdles…


Finally,Nepal government, Ministry of Information and Communication have decided to adopt a technology neutral policy to allow operators to lunch 4G using the 1800-MHz. So now operators can lunch the 4G service to its customers.


Before few weeks, Nepal Telecommunication Authority(NTA) : a government head body that monitors, governs and regulates the telecom operators  in Nepal: announces  that  it is preparing for the frequency spectrum , frequency distribution and cost analysis &  also announces for submission of proposal  for 4G operation to the operators. This declaration has opened the door for the telecom Operators to lunch the 4G LTE service in Nepal. This announcement has been taken a good response from the public people as well.

Is it really a 4G or LTE???

4G is the 4th generation mobile data service with its high speed download and upload of packet data.

LTE is Long Term Evolution as the next generation data service aimed to fulfill the demand of 3rd generation data scarcity. LTE have been constantly developed and improved. So LTE-A (A-advanced) is the next generation LTE service. LTE can be upgraded with the utilization on ongoing GSM and UMTS carrier.

Many of us and even operators have been consciously used the term LTE and 4G interchangeably. Technically they are different.  4G define the D/L (Downlink) data rates of 100Mb/s during high mobility i.e during travelling with high speed on bus, trains & 1 Gb/s during stationary. Now let’s examine the speed on those countries where 4G is deployed. The above speed has not been achieved yet. Cellphone power, cell phone antenna, MIMO (Multiple Input Multiple Output), carrier aggregation, etc. are the several technical challenges behind this.

However, on contrary LTE defines the theoretical speed of 100Mb/s as D/L. The practical speed has been varied among operators. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements. LTE have been in operation in 16 countries as of 2015 and is being deployed by 140 operators in 56 countries.

The two major operators NT and Ncell on their statement expressed, they are willing to lunch the 4G LTE service. 
NT plans to provide within all 75 districts of Nepal 4G service by 2017/18 but it hasn’t been able to keep up its place to meet its targets. Since, NT still hasn’t provided 3G service to all over Nepal. Its in the expansion process. So to meets its target is yet dubious and challenging itself.


Ncell now owned by Axiata Group, a competitor of NT has been  focused on quality services with adaption of 3G. Focusing on major cities, it has already provided 3G services. Ncell have shown keen interest for adoption of 4G-LTE  before few months. At that time even NTA had not been prepared and planned for frequency distribution .

5 Essential Tools that Every Telecom Engineer should have on their bag

Being a Telecom Engineer and executing the task is itself a difficult job. Telecom Engineer should always be smart, diligent, sharp, active and problem solving beyond every new faces of problems. 
We should troubleshoot problems no matter what the problems is. 

I have listed top five tools that will help every Site or Telecom Engineer to solve majority of problems. 

1) RJ45 CAT5 Network LAN Crimper Tools, LAN Cable, LAN Tester and CAT-5 connectors:

Lan Crimper along with few(5-10m) LAN cable is very necessary. Few pieces of around 20 connectors will add a life in our task. We can now easily make new LAN cable and use it where we need. 

 We can now even check the existing lan cable faulty with our LAN tester and we can easily replace the existing LAN cable. We can use also use the same LAN cable for interfacing and commissioning new devices as required. So it has been a essential tools that we should not forget under any circumstance.

2) Screw Driver Set: Screw driver is general and multipurpose tools that every technicians and engineer should carry along with them. It accomplished different works.
 It can be used to open the different cards of BBU, RRU and even different Transmission Equipment's like CX, OSN, CISCO, Alcatel,etc. If you find it more bulgy and heavy, never miss the two set tools +/- in big and small size in your bag.

3. Tie Cutter with few Black and White cable tie: To clamp the cable in proper order, we need cable tie. Routing with proper tie makes the site and cables good looking.


Tools is simple but has great use while routing, fixing new and old cables in proper places. Generally Black tie is used at outdoor and white tie is used at indoor. 

4. Multimeter: No matter what new devices and equipment, whom with we play: 
Multimeter has its own remark in the Telecom Engineering. Most common, most versatile and most needed devices that every telecom engineer must posses. Power failure, short circuit, continuity test, current measurement, voltage measurement, resistance measurement,etc are done by multimeter. It has been a major tool for troubleshooting telecom equipment and devices.


5. Labels: Labels are need to show where the cable has been gone and where it ends. In BTS we can see large number of cables routed here and there. If we don't label the cables properly we may incorrectly plugged in and out of other cables and may risk in "site down". " Imagine- If it was a Hub site, then the whole city or region may go silent". The result is worse and even scary. So for proper labeling at both end, we must have either printed or hand written label. So we should always carry blank label in our bag so we can used it for temporary in case needed. 

We can see the labeling done at Fiber Cable , and thus we can easily know where it has been routed. 

I have listed major 5 tools above. Let me know other tools in the comment section below which I have not listed.

China builds fastest supercomputer with it's own advanced "CHIP"

China have been dominating world on Supercomputer battle for few years.

The broadcast center converts all the programming into high quality uncompressed digital stream. The provider needs to encrypt in order to keep people from accessing it for free.

Will Smart Phone become smarter then Human Beings?


As according to "digital trends": a technology sites, 6.1 billion people will have  smart phone by 2020. In USA only more than 42% of US population have iPhone as according to CNN till today.

By 2020 there will be around 8 billion people and by that year 7 of 10 people will have using the smartphone. The reason behind rampant  increase of the smartphone among the people is that they are Incorporating the human side by side in the various activities.
  
#India is the worlds most growing market for smartphone 

One clear example, before 2 decade,you have to remember the birthday of your colleagues or relatives by writing on notebook or diary but now you will get notified the day before. Even if you forget to wish they will remind you with the beep of sound or the alarm.  Isn't they are smart and even smart when you are too busy on your schedule and they just remind your daily routine-meeting with some x,y,z personal.

Smartphone is occupying our natural mind. We are letting them encapsulating our sense. We are trending on their behavior and decisions. People are becoming more lazy that they ain't don't want to use their own instinct for decision making and analysis. They rather depend on the graphs prepared by the set of algorithms. They don't want to take risk by making their own decisions.

In every field, smartphone is gradually making human mind dull. From Share Market and Financial analysis to Education and Weather Forecast , smart phone is intensively-penetrating-moving leaving the foot print unseen as it moves in every peoples pocket, making them more wise in decision making but blunting the human mind instead of sharpening.

We, for our easy and good service, have created it. We have used our own brain to make it smarter. Smartphone may become smarter than the average people but it cannot be autonomous-it will always need human innovation in every paved road of its own way.
