Introduction: Welcome to RF communications

With demand for 5G rising and 6G on the way,

mobile operators need more of everything¡ª

more bandwidth and frequency support, more

capacity and reach, more spectral efficiency

and RF conditioning, more backhaul and power.

That means adding more equipment, ports,

bands and cabling to an already cluttered RF

path. So how do you do it without adding more

complexity? That¡¯s Challenge #1.

Challenge #2 is interoperability. The rate at which new

technologies and applications are coming online is

Simplicity and innovation, agility and sustainability. These

are the hallmarks of tomorrow¡¯s evolved RF path and a more

powerful, prepared and profitable wireless network. We

know because we¡¯ve been involved from the beginning.

accelerating; the interval between disruptions is shrinking.

To stay ahead, you need to constantly adapt your RF path

to capitalize on the opportunities and mitigate the risks.

It means making difficult decisions on how to modernize

and restructure your sites and having the ability to

integrate and deploy the best new technologies and

architectures at the right time.

All the while, there¡¯s simmering pressure to add

sustainability into your solutions and network, while

deploying at the lowest CapEx and OpEx. Consider that
