Making Broadband Accessible
To make it available and affordable you will need
• An efficient capacity coverage with the right access spectrum
• A cost effective wireless backhaul solution

Access Aggregation Core
More Capacity. Much More
• Aggregation level is where things don’t add up
• Small cell planners look at the macro cells for aggregation
• But also more availability and operational efficiency
