Advantages of Fiber To The Village project.



Fiber To The Village is the brain child of many professionals working abroad from India, Srilanka and Nepal.
They found Fiber Optic Communication Technology - FOCT is going to be the catalyst for their nation growth like what happened during industrial revolution. In olden days the civilization started on the banks of river, later railway network paved the way for economy growth of the place where it is connected.
Future revolution is the knowledge based revolution and hence we are working to construct the super powered information highway.

Apart from the major benefits that fiber communication brings to one place, there are lot of value added advantages like good world class online education, real time tele-medicine facility, updated weather report with demand and supply statistics for agriculturist and farmers.
Fiber to the Village improves the online retail marketing which is an untouched segment in rural places for many years.
Let us see about the advantages of the other side of the coin using FOCT. When fiber is there at every remote place of the country, the congestion in the urban area will reduce automatically resulting in excellent improvement in current urban problems like air, water, land, noise - pollution, traffic congestion, high cost of living and transport problem.
Communication is the real need of human kind as we are the only species who use communication to the scale which other living being cannot even think of doing so.

Present days demand for youtube, facebook, google, Over The Top applications, high definition TV, needs lot of bandwidth on the communication highway to handle traffic which is an ever growing phenomena on the trends and taste of the people real time sharing life style.

On the point of global security, we can say world is moving to the safer destination than ever with the implementation of street cameras, face detection, face recognization and face tracking. More bio-metric analysis needs more powerful processors which can be controlled from world center point there by reducing the crime rate to almost nil. Here also FOCT finds the solution for the same under cloud computing.

Once we have everything what we want at our desk at any time we need, what else there we need in this world. here too our FOCT ready with the answer which is related to our human mind.

None in the world is as powerful as our mind power. With FTTX enabled online education system, we will be learning a lot, experiencing a lot, sharing our knowledge a lot. Finally we will start working towards integrating our knowledge and skill under the concept of crowd sourcing to literally find the solution for any problem in this world in no waiting time.

Sounds great right :) Now we have to think on how to achieve this. Have a look at our blogspot for more technical proposal:

FTTV - Fiber To The Village. A practical approach.

FTTX - An overview


FTTX is broadly classified based on the last mile fiber termination such as FTTH - Fiber To The House, FTTC, - Curb / Compound / Campus, FTTB - Building, FTTD - Desk. In that context FTTV was born, meaning Fiber To The Village. This idea is derived from the immediate huge bandwidth requirement in the rural areas where there is not much internet penetration. FTTX is based on the GPON - Gigabit Passive Optical Network technology where all the users are collectively under the same Passive Optical Network which is termed as a PON. Normally there will be 32, 64 or even 128 customers sharing the same optical port from the central office. FTTX brings triple play service namely Voice, Video and Data. The uplink and downlink are operated in two different wavelengths so that only one fiber is used per PON. As per the present technology we can get 2.5 Gbps download speed and 1.25 Gbps upload speed shared among all the users in the PON. Below is the typical network diagram of a FTTX network.


Typical PON structure


As per the implementation, single PON consists of 32 customers with the split style of 2X16 or 4X8. The concept is to take one fiber port from central office equipment OLT, divide that into two and then each output will again be divided into 16 so as to get 32 end point for customer premises equipment. This is different from 4*8 = 32 split as show in the below diagram.





FTTV - Schematic

Fiber To The Village is best achieved by using the existing operators spare fiber in all their national fiber network. The idea is to avail only one fiber between all the joint locations and connect the 1:2 splitter with one side customer equipment and other side to the next 1:2 splitter in the route. So the final network will look like the star topology with the city at the middle having the central office with uplink connectivity and serving all the villages in all the connecting national high ways as shown in the figure.


FTTV - A practical approach

Below diagram shows the practical implementation proposal for Madurai like place in India, which connects all the possible village all along the route on the connecting National and State highways. The central office equipment in Madurai like cities will be connected to the uplink for Internet, IPTV and voice communication. This is the best way as of today to light up all the rural villages with state of the art and high speed internet connection. 

FTTV - Points for Project Planning

Practically there are lot of in difficulty in achieving this FTTV network architecture due to the present system design based on the FTTH and FTTB scenario. In FTTH and FTTB the maximum logical distance between the first ONT and the last ONT should be 20 Kms and this to the maximum distance of the last ONT from the central office. The split ratio and the optical power at all the ONTs are equal due to uniform split of 1*2*16 or 1*4*8. Here in FTTV we have to split 1:2 and connect ONT at one side and feeder to rest of the ONTs in second side. This will have difference of optical power at all the ONTs in the PON. These points to be noted and get specially manufactured or configured equipments for FTTV implementation. Hope technology vendors will come up with suitable solution for the huge market such as India.

Korea's WiMAX..

WiBro is an acronym for wireless broadband and is actually a term that is in the process of being phased out in favor of the more collaborative and generic Mobile WiMAX. Korean standards makers early on adopted the term to describe their initiatives towards adopting a version of the 802.16e standard.

Basically, the Korean standard chose to accept a specific mobile WiMAX iteration of 802.16e, rather than any future version that included backwards compatibility to fixed wireless 802.16 systems. Korea enjoys probably the most extensive 3G deployments in the world already, and its fixed broadband access per capita is the highest in the world. What it needed was an improved mobile broadband. In fact, the Korean government issued the first three deployment licenses for WiBro/Mobile WiMAX in January of 2005.. Since the WiMAX Forum has chosen to interoperate with WiBro/Mobile WiMAX, this will ultimately result in compatible systems.

WiBro/Mobile WiMAX in many respects is driving the mobile side of WiMAX at least from the point of view of vendors eager to provide products to these early deployments. This decision however, results in a backwards compatibility problem with Fixed WiMAX standards or 802.16-2004. The economics of mobile WiMAX however are too compelling to ignore the far majority of Forum members have already solidified on a 802.16e approach.

About HSDPA

High-Speed Downlink Packet Access (HSDPA) (Sometimes known as High-Speed Downlink Protocol Access) is a 3G mobile telephony protocol in the HSPA family, which provides a roadmap for UMTS-based networks to increase their data transfer speeds and capacity. Current HSDPA deployments now support 1.8 Mbit/s, 3.6 Mbit/s, 7.2 Mbit/s and 14.4 Mbit/s in downlink.

Further speed grades are planned for the near future. The networks are then to be upgraded to HSPA Evolved, which provides speeds of 42Mbit downlink in its first release.[1]

In addition to supporting high data speeds, HSDPA greatly increases the capacity of the network. Current HSDPA networks have the capacity to provide each customer with 30 gigabytes of data per month in addition to 1000 minutes of voice and 300 minutes of mobile TV.[1]
