1 Design MAN WLAN Onno W. Purbo

2 Understanding.. WLAN Bandwidth Channels Propagation Designing the MAN Inserting Point to Point (P2P) Links

3

4 Additional Channels in Some non-US equipments MHz MHz

5 Single Channel Spectrum

6 Orthogonal Channel Set Channels set that provide enough frequency separation to co-locate three RF links without interfering with each other.

7 From Waverider Measurement

8 Orthogonal Channel Allocation

9 3 Orthogonal Channel Sets 3 orthogonal channels GHzch GHzch GHzch. 11 Better separation

10 4 Orthogonal Channel Sets 4 orthogonal channels GHzch GHzch GHzch GHzch. 13 Better for dense areas Not enough separation Using non-US equipments

11 Attenuation: Propagation & Range

12 MAN Design Based on 3 Orthogonal Channel Set

13 Omni at BTS

14 Radio Coverage

15

16 Using Sectoral Antenna Better Design & Density

17 Sectoral Antenna

18 120 deg Sectoral Antenna

19 3 BTS MAN 120-deg Sectoral

20 MAN Design Based on 4 Orthogonal Channel

21 90 deg Sectoral Antenna

22 4 Channel MAN Design

23

24 Insertion P2P Links Base Transmitter Stations use Omni or Sectoral antenna. It is vertical polarization. Use Horizontal Polarization for P2P link for adding 3dB separation.

25 Bandwidth Allocation
