Why doesn't WhatsApp work over the internet - briefly?
WhatsApp does not work over the internet because it relies on a unique identification process that requires a phone number and SMS verification for initial setup. Additionally, WhatsApp uses end-to-end encryption, which is tied to the user's phone number, making it incompatible with traditional internet communication methods.
Why doesn't WhatsApp work over the internet - in detail?
WhatsApp, one of the most popular messaging platforms worldwide, operates primarily using internet connectivity to transmit messages, make voice and video calls, and share media. However, it is important to note that WhatsApp does not function solely over the internet in the traditional sense but rather relies on a combination of internet access and phone numbers. This dual dependency is crucial for understanding why WhatsApp might not work over the internet alone.
Firstly, WhatsApp uses your phone number as your unique identifier within its system. When you sign up for WhatsApp, the app verifies your phone number through a code sent via SMS or a voice call. This process ensures that each user has a distinct and verifiable identity, preventing fraudulent accounts and maintaining the security of communications. Without this initial verification tied to a phone number, users would not be able to create an account or access WhatsApp services.
Secondly, while messages and media are transmitted over the internet using end-to-end encryption for security, the app also relies on traditional telecommunication networks for certain features. For instance, voice and video calls on WhatsApp use a technology called WebRTC (Web Real-Time Communication), which is designed to work efficiently over both Wi-Fi and cellular data networks. However, the initial setup and ongoing verification of these communications still rely on the phone number associated with your account.
Moreover, WhatsApp's reliance on phone numbers extends to its group features as well. To add a new member to a group, the app requires that the new member's phone number is available in the contact list of one of the existing members. This ensures that only authorized and verified contacts can join group conversations, preserving the privacy and integrity of group communications.
In summary, WhatsApp does not work purely over the internet because it integrates traditional telecommunication methods into its functionality. The app's reliance on phone numbers for user identification, verification, and certain features ensures a higher level of security and trust within its communication network. This combination of internet connectivity and phone number verification makes WhatsApp a robust and reliable messaging platform, even if it does not operate exclusively over the internet.
