The WAV3000 supports standard MPEG Transport Stream input and output in either
/ u2 Z) t/ D# S$ e& \ J a! ZParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
0 ]9 ~0 t5 l, v: g* l" Z
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
" }' V) v$ S+ Y$ `! v& `; Y6 k8 wdifferent 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
! B3 _+ T7 t" t9 K- }power 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

! Z. Y/ i$ p5 a* x+ q! n
The communication is authenticated and the media stream is encrypted to assure for
: ^: D- W* h: R' P+ _, q9 jprotection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
" U- D$ Q) Q' Y
ensures private communications between each pair of units. This also allow for coexistence of
! g* ` R$ d/ k/ `# J0 L
multiple pairs of simultaneous operations without cross talk.
