Explanation:

All statements are correct.

• Gigamesh has been developed by Astrome, a deep-tech startup expediting the implementation of 5G and rural telecommunications infrastructure through its patented millimetre wave E-band radios and satellite communication solutions.
• It will address congestion issues in rural 4G infrastructure and provide high-tech and affordable internet connectivity. 
• The startup is supported by AI & Robotics Technology Park (ARTPARK), the Technology Innovation Hub (TIH) at the Indian Institute of Science (IISc).
• It's a network solution which will wirelessly provide fibre-like backhaul capacity and pave the road for 5G.
• It is the world's first multi-beam E-band Radio that is able to communicate from one tower to multiple towers simultaneously while delivering multi GBPS throughput to each of these towers. 
• A single GigaMesh device can provide up to forty links with 2+ Gbps capacity, communicating up to a range of ten kilometers.
• Gigamesh features multiple point-to-point communication in E-Band, lowering cost and is driven by software to make it easy to deploy, maintain and repair remotely.

Hence option 4th is correct.
