Despite being one of the biggest cellular telecommunications conglomerates, Airtel users still find it difficult in various parts of the country to catch a strong signal. Our customers complain about the call drops and poor voice quality in Airtel. This problem is partly because of the huge customer base throughout India with limited cell towers. Other reasons for poor cellular network is the landscape of our country and infrastructure. The problem is not limited to rural areas where the cell towers are low, it also persists in major cities because of infrastructure and high rise buildings. Concrete, metal and cement also play a huge role in blocking the signals. Rough terrain like mountains play a significant role. In fact weather can play a significant role in cellular network.
