After a long wait networking at Doti finally started in mid of November 2011. Initially, it was planned for June/July 2011. But heavy downpour and poor weather conditions made it impossible to work during monsoon season. All the equipments required for the networking were already in place and had been moved to the World Food Program Dadeldhura office by the end of June, making travel much lighter and hassle free (even then our luggage was overweight by 15 kg, but we were able to convince airport crew about our project and didn’t have to pay for the extra weight).
With detail plan and preparation, networking team (Ram Krishna Singh and Basanta Shrestha) boarded Buddha Airways for Dhangadhi on Nov 18th. At Dhangardi, in hazy evening we strolled down in search of iron poles required to hold antenna in place and make them stable. One of the main reason of unstable Internet connections in the existing schools and relay points at Dadeldhuda, we found, was due to the constant wavering of the antenna position. This time, with these poles in relay points and schools, we wanted to negate this effect to large extent. At Puri Suppliers, Chauraha we bought around 35 ft of iron pipes and had them cut to pieces, of required length. We walked back to hotel discussing next day’s plan.
At Silugadi, our first task was to get new ADSL line from Nepal Telecom Office. Before getting a line, we talked to a NT staff, who had agreed to put relay at his home in our survey visit. But to our surprise and dismay, he started asking for personal favor. We were in no position to meet his demand and instantly started working on alternate plan. Fortunately, near by Ncell tower, there was a FM station, Saileshwori FM, with ADSL line. We approached them and discussed about possibility of sharing the ADSL line. Station manager was very excited about our OLPC project and was more than happy to help us for which he thought is noble cause. After meeting, Basanta started his at FM station, and I walked to the Ncell tower to manage a separate power line for our antenna.
Ncell tower supervisor, Besh Raj, was waiting for us at Silugadi tower. We asked him if he can arrange a helper to fix antenna at Ncell tower. Besh Raj was very amicable and managed one college student Lokendra, who later on turned out to be a very quick learner and remained with us for good 10 days. With the help of Lokendra, we fixed two antennas at Ncell tower, Silgadi one pointing towards Khatigaun Ncell tower and other to Mauwa relay point. Satisfied with day’s work we went back to lodge [Lord Buddha] where we have set up our base.
Early in the morning, Lokendra showed up in the lodge with his friend Basanta and we were team of four. After an hours drive from Silgadi, we reached Khatigaon and fixed two antennas in Ncell tower one pointing Silgadi and other to Mahadev school relay house. Another major relay point was Ncell tower at Mauwa VDC. After long discussion, we planned to connect Mauwa relay point to Silgadi first, then connect Khatigaon to School Relay house later, and accordingly headed towards Mauwa.
Near by Mauwa Ncell tower, in the direction of Silgadi, there was small hillock which blocked clear visibility of Ncell tower at Silgadi. But we kept working hoping that it won’t affect much. By this time, WFP staff Rajan Khatiwada got so much interested in our work that he started climbing up and down the Ncell tower(which normal people including me would not dare) and fix the clamp and antenna. After completing setup we tried connecting it to Silgadi relay point, but it didn’t work out. Tried all the tricks but in vain. Tired and frustrated we all came back to local lodge “Nawaraj Ko Hotel”. One good thing about this lodge is it’s food. Highly recommended lodge to be in if you ever happen to visit this place.
Next, we sent Lokendra to Silgadi end to fine tune antenna while we stayed back. There was load shedding in Silgadi and couldn’t test connection till afternoon. We fine tuned antenna at both end but still there was no sign of any connection. At this point, we cursed ourselves for not learning ”Radio Mobile” software and checking the viability of connection in this software before implementing it.
Radio Mobile is a free and powerful tool used to predict the performance of a radio system. It uses digital terrain elevation data for automatic extraction of path profile between an emitter and a receiver. This data is added to system, environmental and statistical parameters to feed the Irregular Terrain Model radio propagation model. Elevation data is also used to produce virtual maps in background. Radio Mobile can be used to plot coverage and design radio links. It is able to create plot that is as accurate as the plot from expensive commercial packages used by my hardware vendors.
Lesson learnt, from now on, we will make sure that performance and viability of connection of the radio system in Radio Mobile is checked prior to its implementation.
Here we were on the 7th day(25th Nov) of the actually planned 12 days trip with nothing working on our favour. We haven’t connected even a single relay point, forget about the schools. Team members, specially Basanta, was having sleepless night with constant coughing. Frustration and fatigue started showing up in the form of irritation and differences among the team member even in minor issues. In the evening, wearing long faces, we were shambling around the Mauwa tower and approached to near by hillock to have a view towards Silgadi. To our surprise and entirely unexpected, Silgadi relay point and both schools Sri Saraswati & Durga Primary were visible from this vantage point. Suddenly with renewed hope we discussed connecting Saraswati and Durga school with Silgadi via Khatiwada gaon and Bajh ko Mod relay points. With this new plan and little remaining hope, we came back to Silgadi, arranged necessary equipments for new Khatiwada relay point and Saraswati Primary School. We called and explained our new plan to Shiva Raj Khadga sir from Saraswati and asked to make necessary arrangement accordingly.
Next day, before heading to Khatiwada gaon, we fine tuned the antenna, checked and reconfirmed the connection at Silugadi tower. After 2 and half hours walk, we reached the destination. After short discussion and agreement with principle at Shree Devi school at Khatigaon, we used this point as one of the relay point as we had planned the previous day. With clear line of sight and shorter distance, connecting these two points were pretty easy.
