Smart antenna boosts basestation capacity
Paratek Microwave will premiere its DRWiN (dynamically reconfigurable wireless networks) GSM antenna at the 3GSM World Congress this week in Cannes
DRWiN GSM is the first antenna to support GSM, GPRS and Edge with a simple interface into the basestation. It uses analogue phase shifters to produce multiple simultaneous beams, independently steerable in each time slot. These phase shifters are made from Paratek's revolutionary Parascan materials technology.

Rappaport joins wireless industry experts
Paratek has welcomed Dr Theodore (Ted) Rappaport to its Advisory Board of wireless industry experts
President and chief executive officer Ali Pourtaheri explains: "Instead of pursuing the traditional approach of digital beam forming, Paratek has developed the DRWiN antenna which forms beams in the RF domain.
Studies have shown that the cost-to-performance advantage of this solution far exceeds any existing smart antenna solution in the market.
Furthermore, the beam controller of the DRWiN GSM antenna reduces integration risk to the network operators.
Operators will have a strong business case for incorporating the DRWiN GSM antenna into their networks".
The DRWiN GSM antenna delivers better than 21dBi of receive gain and better than 18dBi of transmit gain.
It supports multiple (up to 24) independently steerable narrow beams with selectable beamwidths, and increases carrier-to-interference ratio by 10dB.
Importantly, it improves frequency reuse from 9 to 4 and doubles the capacity.
The DRWiN GSM antenna consists of a receive (RX) antenna panel, multiple transmit (TX) antenna panels and a multi-beam controller (MBC).
This design supports up to 12 carriers with dual polarisation, providing polarisation diversity.
The width of each RX beam can be adjusted.
The transmit antenna consists of multiple antenna panels (up to six per sector), each panel capable of providing two orthogonally polarised, electronically scanning beams and a single, fixed sector beam.
The two scanning beams are designed to support two independent carriers and the single sector beam provides full sector coverage for the GSM control channel.
The MBC controls the beam directions of the RX and TX antennas as well as the RX beamwidths through an interface with the basestation.
Information such as framing and frequency-hopping schedules are provided to the MBC to compute the angle to point the beams at the appropriate customer.
