Everyone knows what Bluetooth is. So, I will shed some light on the basics of Wi-Fi Direct only.
What is Wi-Fi Direct?
It is wireless standard based on IEEE 802.11 WLAN, which allows devices to connect with each other and share data without using an access point. Its capability to do away with hardware wireless access points has greatly reduced the setup time for connecting devices wirelessly. Actually, Wi-Fi Direct devices create a soft access point for sharing data. Therefore, upgrading a device to support Wi-Fi Direct is not a major issue. If you are using a device running on either of the versions mentioned below, or a more recent version of the corresponding mobile OS, then your device can support Wi-Fi Direct: Android 4.0 Ice Cream Sandwich, Blackberry OS 10.2.1, Windows Phone 8.1, and iOS 8.
Traditional hearing aid setups include a transmitter case and an ear-mold. The ear-mold is worn on the ear and can be customized to individual size and comfort. The case is usually worn behind the ear, and contains the circuitry required for the working of the device, the battery, and the device control system. The ear-mold contains the speaker. Electric routing of sound takes place over a connection (wired or wireless) between the case and the mold. The mold contains a plastic tube that delivers proper sound as received to the user’s ear.
Although traditional hearing aids are still widely popular, wireless hearing aids are fast starting to create a place for themselves. Amongst the more recent wireless hearing aid developments, Bluetooth hearing aids are a crucial innovation. In addition to functioning as a regular hearing aid, a Bluetooth hearing aid allows a person with affected hearing ability to modulate audio using a device that streams Bluetooth transmission from other Bluetooth-enabled consumer electronic devices such as cell phones, music players and TVs. These hearing aids operate in the 2.4 GHz frequency.
