2 Objectives for Today Background Who are we? Radio Spectrum Congestion Overview on MiMO / Space-Time Products OPV (Optimised Protection Variant) NDL (Network Digital Link) MDL (Multi-Point Digital Link) Antennas Network Management Options

3 Tait Electronics An Overview Private company formed in 1969 by Sir Angus Tait Fostered single-minded commitment to radio communications Charitable trust status ensures that decisions are made for the long-term Virtually all profit is re-invested in R&D & new technology NZ s Largest Electronics Company Largest Electronics R&D Facility in Australasia 900 Staff Employed Worldwide 95% of Product Exported - Now found in almost 160 Countries

4 Tait Products Services Portables Mobiles Base Stations Taitnet Trunked & QS Networks Digital APCO P25 & DMR

5 DESIGN & MANUFACTURE 250 Engineers Modern Design Techniques Latest Portable 97% of Components fitted by SMT Test 80% of Functionality while still on SMT Line 3 Person Assembly Line

6 Tait Europe Founded 1978, based in Huntingdon, Cambridgeshire Satellite offices in France, Germany, and FSU Spain, Scandinavia, Balkans Employs over 60 staff in Sales Systems engineering Workshops (build + repair) Operations / logistics Marketing Turn-key solutions design, build, project manage, deploy and maintain

7 And.. MiMOMax A New Entity, from the Wireless Research Labs at Tait Electronics, Specialising in the Application of High Performance Advanced Wireless Technologies to Mission-Critical Applications Spectrally Efficient Solutions

8 Congestion in the Radio Spectrum Spectrum is Finite! More Users/Apps on Finite Spectrum. Increasing Demand for; Higher Data Rates. More Robust Wireless Channels that Better Manage Signal Fading and Multipath. Better Quality of Service Simpler Ubiquitous Interfaces.

9 Spectrum Costs / Availability Frequency usage fees in various countries: Australia Singapore Taiwan Mobile French Govt FreqUsageFee FreqUsageFee = ( BW ) FreqUsageFee = K, ( Si Gi) Bi Ai $300 : BW < 1MHz 25kHz ( BW 1MHz *$300 + $12000 : BW 1MHz 1MHz BW W FreqUsageF ee = K d 12.5kHz 25W a BW : f 0 960MHz = a BW 0.96 : f 0 > 960MHx In each of these licensing regimes, the frequency usage fee is tied to a Bandwidth multiplier. e.g 2 x BW= 2 x Cost

10 Why MiMO Spectral Efficiency No Better way to Get more Throughput. More Users /Appliances on Networks Provides; More robust channels Supports Open IP Standards. QoS Many Standards Incorporating MiMO MiMO enables an increase in capacity & quality of wireless channels to dramatically improve the performance of wireless communications systems

11 Spectral Efficiency Next Big Capacity improvement Freq. subdivision 100kHz > 12.5kHz > 5kHz ~ 20 : 1 improvement in 50 years Cellular channel reuse ~100km > ~0.3km (micro-cell) ~ 300 : 1 improvement CDMA ~ 20 : 1 improvement Space Time / MiMO ~ 2-10:1 immediate future ~ 100 : 1 potential improvement Applicable to all Future Standards (and some current and emerging standards) Applicable to both point-to-point and mobile access schemes ( mobile is a bit more challenging) Basic principles now proven by many researchers

12 MiMOMax Wireless Limited What We Do Then MiMOMax utilises MiMO and Space Time Coding technologies to provide high reliability, high efficiency ultra low latency, linking solutions in narrowband licensed channels to ensure reliable and interference free operation

13 Basics So how does MiMO Work?

14 Receiver Diversity TX Data TX Data RX Data n R (independent) views of TX signal. Diversity = n R No direct increase in data rate

15 Transmitter Diversity TX 1 1 RX TX 2 2 RX TX Data Encoder TX 3 3 RX Decoder RX Data TX n T n R RX n T (independent) paths to receiver. Diversity = n T No direct increase in data rate

16 Multi-user Detection TX Data 1 TX 1 1 RX TX Data 2 TX 2 2 RX Encoder TX 3 3 RX Decoder RX Data 1 RX Data 2 TX n T n R RX Two independent transmitters each signal recovered with diversity = n R. 2 x users = 2 x data rate

17 MiMO Concept TX 1 1 RX TX 2 2 RX TX Data Encoder TX 3 3 RX Decoder RX Data TX n T n R RX Total number of paths between TX and RX = n T x n R. Can arrange as n T channels each with diversity =n R. =n T x data rate

18 Eg 2 x 4 MiMO n T n R Tx Data Space-Time Encoding Tx Data =>n T x channel data rate Space-Time Decoding Rx Data

19 MiMO / Space-Time Multiple Input Multiple Output Uses multiple antennae at each end to get more information through a channel Provides better quality through diversity Different information transmitted from each antenna on same frequency! Space-Time Information is encoded across space (different antennae) and time
