Ahmedabad district is built around the Sabarmati river and the old walled city on its east bank, and it reaches far beyond the city limits. Its talukas include Daskroi, Sanand, Viramgam, Dholka, Bavla, Dhandhuka, Mandal, Detroj-Rampura and Dholera, and the districts of Gandhinagar, Kheda, Anand, Mehsana and Surendranagar lie around it. Freight leaves by many doors. NH 48 connects the city with Mumbai and Delhi, the Ahmedabad to Vadodara expressway gives a fast road southward, and NH 147 runs to Gandhinagar. Kalupur is the main railway station of the city, and Viramgam Junction sits where lines to Mehsana, Surendranagar and Saurashtra meet. A truck leaving an Ahmedabad yard can be on any of these roads within the hour, and the owner sitting in an office has no way to see which one it chose.
Cloth and chemicals are old trades here, and the city has long been known as a centre of cotton textiles and denim. Industrial estates in Vatva, Naroda and Odhav hold small factories that make dyes, chemicals, machine parts and garments, and many of them hire trailers by the trip. Pharma makers have plants in and around the city, and Sanand taluka has car assembly lines together with their parts suppliers, as well as electrical equipment works. A supplier who ships pressed parts or rolls of cloth on a hired vehicle usually knows the loading time and the promised arrival, and nothing in between. A magnetic tracker closes that gap without asking the transporter to fit anything.
The district also has roads that are less about factories. Viramgam has a container depot connected by rail to Mundra port, so boxes arrive and leave by trailer on the last stretch. Dholera, in the south-west, is planned as a new industrial region and attracts construction trucks and heavy machines. Nal Sarovar bird sanctuary and the Lothal archaeological site bring tourist buses on weekends, while the Sabarmati riverfront and Kankaria lake host fairs and events that need rented gear. All this means that Ahmedabad has a great many items that do not belong to a regular fleet: hired cranes, scaffolding, generator sets, borrowed trailers and sealed cartons. Those are exactly the things a battery GPS tracker suits.
