Wi-Fi (Wireless Fidelity):

Wi-Fi is a technology that allows devices to connect to a local area network (LAN) wirelessly, enabling communication between devices and access to the internet without physical wired connections. It operates based on the IEEE 802.11 family of standards and uses radio frequencies to transmit data.

Technical Components:

  1. Radio Frequency: Wi-Fi operates in the unlicensed radio bands, typically 2.4 GHz and 5 GHz frequencies. These frequencies are divided into channels that devices use to communicate.
  2. Access Points (APs): Devices connect to a Wi-Fi network through access points. An access point is a hardware device that creates a Wi-Fi network, allowing wireless devices to connect to it.
  3. Wi-Fi Standards: Standards such as 802.11ac, 802.11ax (Wi-Fi 6), and 802.11ay define the protocols and technologies used in Wi-Fi networks, offering different data transfer rates, frequencies, and features.

VoLTE (Voice over LTE):

VoLTE is a technology that allows voice calls to be transmitted as data packets over LTE (Long-Term Evolution) networks, which are high-speed wireless communication networks used by mobile phones.

Technical Components:

  1. Packet Switching: VoLTE uses packet-switched networks (IP networks) to transmit voice data in the form of packets. This differs from traditional circuit-switched networks used for voice calls.
  2. IP Multimedia Subsystem (IMS): IMS is a framework used in VoLTE that allows for the delivery of multimedia services over IP networks. It enables the integration of voice, video, and other multimedia services.
  3. Quality of Service (QoS): VoLTE incorporates QoS mechanisms to ensure a certain level of service quality for voice calls over LTE networks. It prioritizes voice packets to minimize latency and ensure a stable connection.

Wi-Fi Calling with VoLTE (Wi-Fi VoLTE):

Wi-Fi calling with VoLTE refers to the ability of a mobile device to use both Wi-Fi networks and VoLTE technology for making voice calls. This feature allows seamless handover of calls between Wi-Fi and LTE networks, providing better coverage and call quality in areas with poor cellular reception but a strong Wi-Fi signal.

Technical Aspects of Wi-Fi VoLTE:

  1. Seamless Handover: When a call is initiated on VoLTE and the device moves from LTE coverage to a Wi-Fi network (or vice versa), the call can seamlessly transition between the two networks without interruption.
  2. QoS Management: The device and network prioritize voice packets over other data traffic, ensuring a consistent and reliable voice call experience.
  3. Protocol Integration: Both Wi-Fi and VoLTE technologies need to integrate seamlessly within the device's hardware and software to enable Wi-Fi VoLTE functionality.
