5 THINGS YOU SHOULD KNOW ABOUT FRONTHAUL

Felipe Sevillano, Transport & Data Planning Department, TELECOM PERSONAL PARAGUAY

1)       WHY FRONTHAUL?

The only way to deal with the data storm is to have denser wireless networks with increasing spectral efficiency. One way to deal with this is RAN centralization using macro sites for resource pooling and implement antenna distribution and remote RRUs.

2)       CAPACITY REQUIREMENTS

For CPRI without compression the capacity requirements are as follows:

CPRI with compression in a 2.5 ratio requires the following capacities:

As you can see compression of CPRI will likely be required to make wireless CPRI Fronthaul a reality.

3)       LATENCY REQUIREMENTS

CPRI latency requirement (<200us) will demand the use of ultra-low latency Fronthaul solutions

4)       FRONTHAUL AND SMALL CELLS

Operators will use a combination of CRAN/RRU and Small Cells

5)       TRANSPORT FOR FRONTHAUL
