but it is not always available

it can be costly

or too time consuming to deploy

Fiber can do the job, where possible.

Did someone say

small cells and didn’t

get any backhaul?

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
