WiFi: Comparison of WiFi Direct vs WiFi Aware vs BLE vs Adhoc mode (802.11)

Summary
WiFi Aware - service discovery that helps setup WiFi Direct links.
BLE - service discovery and P2P connection.
WiFi Direct - P2P connection
WiFi Adhoc mode - basic P2P connection (legacy mechanism)

We will now differentiate between each of these protocol suites and their applications.

WiFi Aware vs BLE
- WiFi Aware has a longer range (because of wifi power limits)
- works with existing WiFi chips (protocol overlay - Phy is mostly the same)
- higher bandwidth than BLE (faster for gaming etc) - this is because it will use WiFi Direct once wifi aware discovers the service.

- WiFi aware works across brands of phone vs ibeacons which will work only on iPhones for e.g.
