She is among the twenty high school students of Perpanncholai village in Namakkal district who flock to the banyan tree every morning for their online classes. Since her village is located on the foot of Kolli hills, the mobile coverage is patchy. “At least half a dozen villages in this area suffer from poor signal problems affecting the studies of such students. There is a lone BSNL tower for this area and unless more towers are added the future of students could be in jeopardy,” said Nalvinaichelvan, a local activist. He pointed out that students in other villages climbed onto small hillocks in their area to get better mobile signals for their classes. “They even carry their lunch with them,” he said.
