Agenda

1. Microwave background and applications2. Technology explained 3. Microwave: a solution comparison4. SAF projects in the Benelux5. Conclusion

Microwave background and Applications

• Bandwidth, speed, flexibility and redundancy• Availability of PtP spectrum

Applications• Flexible backhaul for mobile networks and (W)ISP’s • LAN-LAN connections for ‘multi location’ organisations• Business parks, Companies in ‘white spots’ • (remote) homes in ‘white spots’

Backhaul voor public and private networks

Customer application SAF in Benelux

1. Businessparks with 17Ghz Freemile 2. Nationwide backbone for digital FMradio network 3. Redundant 1+1 connection from Harlingen to

Terschelling (over 26km water)4. Campings and marina’s (backhaul for Wifi networks)5. London to Frankfurt (> 600km)

Conclusions

• Microwave links (often) good alternative to fiber (especially when trenching is required)

• Broadband capacity up to fiber standards

• Attractive CAPEX and OPEX

• High reliability of Microwave links

• (near) Line of Sight is important
