Study Notes
Ad Hoc Networks
- Temporarily created for specific purposes in limited areas.
- Two main setups: Open Wi-Fi and tethering/personal hotspots.
Ad Hoc Network Advantages:
- Simplified Connection: Easier and faster to connect devices, ideal for users with limited IT knowledge.
- Reduced Costs: No need for a central access point like a router, saving money on equipment.
Ad Hoc Network Disadvantages:
- Slower Performance: Devices using ad-hoc mode typically support slower transfer speeds.
- Weaker Security: Wireless connections are inherently less secure than wired connections, and lacking a central security manager increases vulnerabilities.
- Open Networks: No encryption, vulnerable to unauthorized access and misuse.
Performance Issues:
- Maximum Speed: Ad-hoc networks have lower maximum data transfer speeds than infrastructure mode networks.
- Interference: Ad-hoc networks experience increased interference due to multiple devices connecting and moving around.
- Maximum Range: Wireless routers have stronger antennas, offering wider coverage than direct device connections.
Ad Hoc Network Interference:
- High device connectivity and movement increase interference as each device has its own connection.
Network Coverage:
- Cities: Excellent coverage due to high population density and investment from telecom providers.
- Developed Countries: Adequate coverage due to investment in network infrastructure.
- Developing Countries: Limited coverage and slow speeds due to insufficient investment in network infrastructure.
