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
What’s The Status for 24GHz in SA?
• It is an ISM band, but it’s not• 24GHz equipment has been Type Approved
What’s The Status for 24GHz in SA?
• Non-Specific SRD - Short Range Device• Security Scanners• Some RFID based devices
• FDDA - Field Disturbance and Doppler Apparatus• Used in automotive applications for collision
detection, obstacle detection, blind-spot monitoring, and also to assist in automatic cruise control

What we need from 24GHz in SA?
• Enable WISPs• No need to re-invent the wheel• ISM model does work, and is less hassle for the
regulator• Power Output - ATPC• We are falling behind other African countries. We
should be leading the field
Let’s talk about cost• Carrier 2.4 or 5GHz
