Facts

Two incompatible standards for 5GHz are operating on adjacent market
segments. 11a in position to win industry standard in the business
environment, HL2 might end to be the home/consumer preferred
solution

Major Players, on both sides, aware of the severity of the situation

Coexistence between the two standards and interoperability within
various operational environments is a key for massive market adoption.

Single Global Solution with a broad industry support is becoming a
Market Need

Main Goals
 Opening the door to a truly Coexistence global marketplace
 Achieving all-around interoperability: same device is able to
connect, be serviced and serve anywhere: Home, Office and
Public

Proposal’s Main Principles
 Keeping it simple
 Combining the best from two standards
 Importing a simplified version of HiperLAN2, and overlay it
over the basic 802.11 MAC
 Dividing the time domain, dynamically, between 802.11a and
HiperLAN2 devices

Summary
 Convergence between 802.11 and HL2 provides the users with
best of two worlds, e.g full interoperability, QoS and Coexistence
 The Solution will enable full Interoperability and Coexistence
only if adopted by both standard committees

Both IEEE802.11 and the BRAN committees should take
immediate measures in order to establish a common forum that
will discuss the implementation of the solution
 hLAN is offering this proposal as a platform for developing a
global solution
