Delivery of Internet to the rural areas has been the point of discussion in various fora for a long time. The delivery through WiFi is envisaged but nobody could put together a solution that would make it a reality.
Any attempt in this direction has been met with cost inefficiencies and/or spectacular failure of the project.
The XtraWiFi team has identified that there is a structural deficiency in the existing delivery mechanisms, which is discussed elsewhere in the document.
Getting Public WiFi working requires that its revenue is at least profitable enough to maintain the infrastructure. Having a huge infrastructure and having to maintain through meager revenue is nothing but straight heading for a tragedy.
In our beta trial, which is commercially launched to study patterns, we have checked the revenue per hotspot. Projections are extended to other markets through statistical modelling./p>
We tried to get the implementation as close to the rural model as possible.
This subject has been most discussed in the media and our leaders. There are about half a million villages in India and little over 10,000 in Telangana.
The commercial private organizations cannot get to the Village level as it is not a lucrative market yet. The infrastructure cost itself is the deterrent.
This is the very problem XtraWiFi addressed in its research started in 2004. The problem of portable computing devices is solved in the meanwhile. It is just the matter of getting the infrastructure in place to get going. It is recommended to read about XtraWiFi before going through the rest of the document.
We have done extensive study on implementation of public WiFi in villages. We have visited various villages and done manual inspection to check the feasibility factors. Google maps has been handy in continuing our study in our office.
Typical infrastructure would consist of
Establishing pop in a town would require two types of infrastructure to be available: local cable operators and infrastructure from telcos. Most small & big towns have these facilities available.
POP would have the following infrastructure:
When such infrastructure is established in a town, XtraWiFi will be provided in the town. Even semi-urban areas like this could be construed as a village implementation; each significant population area like a colony is considered as a village and implementation is executed.
Almost each and every village is connected to the nearest small town through fiber. Though the uptime of this infrastructure is not very good, it is still a connectivity. WIth a little financial incentive, people could be encouraged to maintain the fiber better. Using SLA and redundancy would do nicely.
These operators could be offered revenue sharing to encourage them to join the revolution of XtraWiFi. XtraWiFi has an internal revenue sharing mechanism to address this important part of operations.
With dwindling revenues due to digitization, local cable operators would be happy to have a little extra income in the challenging environment.
Having local manpower to maintain infrastructure is more important than laying the overhanging cable ourselves. Administrative overhead & logistics would be arduous; not to mention the cost of manpower to maintain infrastructure.
The role of the cable operator would be limited to providing connectivity from the nearest town to villages. Using latest PON technology, we could use single core to establish a decent network.
NOFN and various govt activities (like Mission Bhagiratha in Telangana) are in various stages of implementation. At 700 Rs per mbps per annum, it looks attractive to reach from the nearest town to villages, although they say it is promotional tariff.
The advantages are obvious with NOFN. We get underground connectivity. But the implementation of NOFN is not likely to be completed anytime soon. Availability of infrastructure right now is important.
We could use cable TV infrastructure or build own infrastructure with overhanging cable and shift to NOFN whenever & wherever it is available.
Until good infrastructure is put into place, we should use whatever the infrastructure is available or build ad-hoc infrastructure.
XtraWiFi implementation in a village is a straightforward job. We have perfected this part of public WiFi with considerable details.
Fiber landing point or simply landing point is a place where incoming fiber connectivity will be terminated. Requisite power supply is provided at landing point.
Local electricity board provides metered power supply at the landing point.
Typical Landing point is a 3 feet wide, 4 feet high and 1 ½ feet deep box that is mounted either on a pole or clamped to a rigid wall at the center of the village. Permissions for this would be handled by local authorities.
Provision for uninterrupted power supply will be available at this landing point. Typical 6 hour power backup is provided for this landing point.
Each village will have one landing point. Some large villages could call for more than one. The operations team will make this decision. Generally only one lading point is required.
Requisite PoE (Power over ethernet) infrastructure will be available in landing point. This equipment is internally referred to as “Power injector”. This is designed and manufactured in-house.
Wireless Access Points are also known as wireless routers or simply routers. These will be installed on electric poles available in the village. In places where electric poles are unavailable, wall mounted routers will be installed at a suitable location after obtaining permission from the owners of the property.
These routers are installed at 60-80 meters distance from each other; there will be a coverage of 30-40 meters radius by each router. The location of installation will be decided by operations team taking into consideration local conditions.
Most of the villages require 30-50 routers to cover most of the area inside village.
