WBA Says Wi-Fi Can Match Cellular Security with Full Implementation of Standards

The Wireless Broadband Alliance (WBA) has released a new security framework asserting that modern Wi-Fi networks can achieve security parity with cellular technologies—provided organizations implement a comprehensive set of recommended standards and best practices.

A Framework for Enterprise-Grade Wi-Fi Security

The newly published framework consolidates existing technologies and guidelines across key areas, including:

• Mutual authentication and encryption
• Identity privacy and credential storage
• Physical access point security
• Roaming and federation governance

According to WBA, achieving parity with cellular networks depends on adopting the full stack of these recommendations, which remain voluntary for operators and enterprises.

Built on Proven Technologies

The parity claim is based on the combined effectiveness of widely deployed technologies, including:

• WPA3 Enterprise with Protected Management Frames
• OpenRoaming, built on the Wi-Fi Alliance Passpoint standard
• RadSec, a secure protocol that encrypts authentication traffic using Transport Layer Security (TLS)

RadSec is designed to address long-standing vulnerabilities in the traditional Remote Authentication Dial-In User Service (RADIUS) protocol, which still underpins much of global Wi-Fi infrastructure but transmits certain data in plaintext and relies on outdated hashing methods.

Addressing Common Security Risks

The WBA framework also highlights key risks that could undermine Wi-Fi security if not addressed:

• Transition Mode Vulnerabilities: Networks that support both WPA2 and WPA3 may allow attackers to downgrade connections to the less secure WPA2 standard
• Legacy Authentication Methods: The use of protocols such as EAP-TTLS with MSCHAPv2 is discouraged due to known weaknesses in password hashing

These risks emphasize the importance of consistent configuration and avoiding backward compatibility settings that weaken security posture.

Industry Perspective

“By aligning security across devices and networks, Wi-Fi can achieve parity with cellular in both capability and confidence,” said Tiago Rodrigues.

Security experts also support this view. Mathy Vanhoef noted that properly configured Wi-Fi networks can be as secure as cellular systems, though cellular networks often require more specialized tools to exploit.

Implications for Enterprises

For enterprise IT teams and network operators, the message is clear: Wi-Fi security is no longer inherently weaker than cellular—but achieving equivalent protection requires disciplined implementation of modern standards.

As organizations continue to rely on wireless connectivity for critical operations, adopting these best practices will be essential to ensuring secure, scalable, and privacy-preserving network environments.
