A hotspot is a physical location offering wireless internet access. It can be a cafe, an airport, a hotel, or a library. It can also be a personal hotspot from your phone. The term covers both public Wi-Fi and tethering. Hotspots let devices connect to the internet without a wired connection.

Public hotspots are common in urban areas. They are often free but may require a password or a login page. Security is a concern. Open hotspots can be monitored. Encrypted hotspots using WPA2 or WPA3 are safer. A VPN adds another layer of protection.

Types of hotspots

• Public Wi-Fi: cafes, airports, libraries
• Personal hotspot: phone tethering
• Mobile hotspot: dedicated device
• Community hotspot: neighborhood networks

Hotspots bridge the gap between mobile and fixed internet. They are convenient. They are also unevenly distributed. Rural areas may have none. Low-income households may rely on phone hotspots for home internet. The hotspot is a small solution to a big problem.
