9 T! o- Z) o9 P, _) S 2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
' K1 T: j4 [0 P# A0 V different country spectrum requirements.
& p' B0 h2 D0 ]8 e. o+ {3) Dynamic frequency selection to resist interferences.
6 O; Y9 M! v( E# X6 R5 u 4) Close-loop power control to minimize power consumption and be a friendly neighbor to
' [4 W9 L& m; ]* {other WLAN networks at 5 GHz.
0 \5 w9 s }3 @: s9 y" q. j5) Secure networking to assure privacy and content rights protection.
) m- o& Y; m. n; i6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,

$ G& M& j) }3 g' d L# w1 L$ g 9) HCI interface to the host CPU to enable flexible application development at the host level.
# ^7 C/ m& s' D6 s( e+ q8 R: Y. e10) Transmission of IR control signals to the video source devices from the TV location.
. g5 m% `9 g% g3 d$ V; ^% }2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
- C3 J: B& s: l5 f' ^! A5 k Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
* m# i+ P7 }. G! @5 tWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
1 J7 L a. {) d6 L! u6 ` different country spectrum requirements.
The system support data rates from 6 Mbps to 60 Mbps.
The system supports video bit rates from 3 Mbps to 45 Mbps.
Proprietary radio resource control with dynamic frequency selection (DFS) and close-loop
/ |! u7 T) }1 {( E( ], Xpower control (CLPC).
Overall video propagation delay of less than 30 ms.
Receive sensitivity is –86 dBm for video rate of 6 Mbps, and –78 dBm for video rate of 20
