"We have been an Aperto customer for some time and know that PacketMAX is the ideal solution for our offerings... Like many service providers, we are concerned with the cost of deploying and managing WiMAX... with Aperto's WaveCenter EMS product, PacketMAX lets us serve a huge number of customers with exceptional QoS and reliability."

Spectrum is the most precious resource that a wireless operator has, and being able to pack more bits into a smaller chunk of spectrum, leads to the following benefits:

More spectrum left over for future capacity expansion.
In license exempt bands, more flexibility in finding clean spectrum.
Lower co-channel interference in a multi-cell deployment, due to greater separation between cells using the same channels.
