Common Air Interface definition
Common Air Interface or “CAI” means the technical description of QUALCOMM’s CDMA digital air interface specification for communication between cell site or other base station transceivers and Subscriber Units to the extent adopted as an industry standard by the Telecommunications Industry Association (“TIA”) or other recognized international standards bodies. The term “CAI” consists only of (i) the TIA’s IS-95 digital cellular standard, (ii) other CDMA standards which specify the same Physical Layer as IS-95 if approved by QUALCOMM and adopted by other international standards bodies throughout the world, (iii) QUALCOMM’s proposed CDMA2000 standard, and (iv) QUALCOMM’s proposed High Data Rate (HDR) air interface standard.
Common Air Interface or “CAI” means (i) the TIA’s IS-95 digital cellular standard and other CDMA standards which specify the same Physical Layer as IS-95 if approved by QUALCOMM and adopted by other international standards bodies throughout the world, and (ii) the technical description of any third generation CDMA air interface standard for communication between cell site or other base station transceivers and Subscriber Units which (a) is adopted as an industry standard by the Telecommunications Industry Association (“TIA”), the European Telecommunication Standards Institute (“ETSI”), Japan’s Association of Radio Industries and Businesses (“ARIB”) or other recognized international standards bodies, (b) has been approved by QUALCOMM (i.e. QUALCOMM voted in favor of adopting such standard), (c) supports operation with both GSM MAP and ANSI-41 networks in all operational (whether optional or not) modes or configurations, and (d) includes a multi-carrier, FDD CDMA mode of operation and/or a direct sequence, FDD CDMA mode of operation.
Common Air Interface or "CAI" means the technical description of QUALCOMM's CDMA digital air interface specification for communication between cell site or other base station transceivers and Subscriber Units to the extent adopted as an industry standard by the Telecommunications Industry Association or other recognized international standards bodies. The term "Standard" includes only (i) the TIA's IS-95 digital cellular standard and the related standards issued in association therewith (e.g., ▇▇-▇▇, ▇▇-▇▇, ▇▇-▇▇, IS-99), and (ii) other CDMA standards which specify the same Physical Layer as IS-95 if approved by QUALCOMM (i.e. QUALCOMM voted in favor of adopting such standard) and adopted by other international standards bodies throughout the world, and (iii) QUALCOMM's proposed cdma2000 standards.
