Sub 6GHz - SelectaBeam Technology
Plasma Antennas' SelectaBeam antenna designs deliver high-speed beam steering in a range of compact, lightweight and affordable form factors. SelectaBeam antennas are available as both planar and cylindrical designs, providing sub-microsecond beam selection within sectoral or full 360° fields of view, and incorporating optional floodlight and omnidirectional modes respectively.
With low sidelobes and selectable deep nulling capabilities, SelectaBeam antennas provide excellent interference rejection – a key requirement for delivering reliable and high-performance communications networks - particularly in lightly licensed and license excempt bands. Through high-speed directional beam-to-beam switching, SelectaBeam antennas enable efficient spatial-TDMA, resulting in substantial increases in overall network capacity in a wide range of wireless communicatrions applications.
Combining very high-speed beam switching with selectable deep nulling capabilities, our SelectaBeam portfolio of products are our most compact and affordable range of antennas. Key features of our SelectaBeam Antennas include:
- High gain: SelectaBeam antennas provide high directional gain for increased link budgets, significantly enhanced network coverage and capacity, reducing the overall cost of deploying wireless networks.
- Low sidelobes: With low sidelobes, SelectaBeam antennas suppress interference and enhance signal-to-interference ratios – key issues for wireless communication systems, particularly those operating in the unlicensed bands - also enabling improved frequency re-use and substantially higher utilization.
- Selectable nulling: This unique feature allows SelectaBeam antennas to create deep nulls close to the main beam patterns, minimizing the impact of strong or close-in sources of interference.
- High-speed beam switching: SelectaBeam antennas provide sub-microsecond beam selection, enabling efficient spatial-TDMA.
- Low cost: Built from off-the-shelf microwave switching components, SelectaBeam antennas are the most affordable smart antennas on the market.
- Compact and lightweight: with small physical footprints, SelectaBeam antennas are ideally suited to situations where there are constraints on mast size and cost, where space is at a premium or when environmental concerns exist. Their small size makes them easy to install (a “one man lift”), and suitable for both indoor and outdoor use.
- Maintenance free: SelectaBeam antennas require no calibration or on-going maintenance, minimizing total cost of ownership.
