24GHzWhat we need, Where we are, Where we should be

The ISP Industry• Current License Exempt Bands Saturated

• Good enough for last mile, not for Backhaul• Users are demanding more speed, at cheaper rate• Legacy backhaul links limited to +/- 250Mbps• Low latency now becoming an important factor due

to VoIP

ISP’s are typically left with the following choices:• Limit network expansion• Be unable to provide the high bandwidth that their

customers desire, at an affordable price point• Buy spectrum - *Equipment• Use 17GHz - *Cost Point• Deploy Fibre

Fibre

• Cable Theft• Redundancy• Installation/Rollout Time

• Red Tape• Cost - Trunking• Expertise - Skill Set• Link Mobility
