Smart Antenna: Principle
- As user 2 (interferer) moves, Antenna is reconfigured to maintain a
spatial null (zero gain) along interferer direction
- Smart Antennas provide:
- Improved Quality (compensates for multipath effects)
- Increased Capacity (low interference -> more users per band)
(SDMA added to FDMA, TDMA and CDMA)
- improved Coverage (high directivity)
- MicroPhotonics provides: Broadband
(True-time delay) + Intelligence
- MicroPhotonic Smart Antennas have recently been proposed for wireless
capsule endoscopes
