SRAN

Single RAN

3 © Nokia Solutions and Networks 2015

Why is SRAN a topic today?

Exponential traffic growth

LTE: new spectrum, many bands

GSM and WCDMA stay for foreseeable future

SRAN:

• flexibility in spectrum use and investment

protection

• longer life for GSM and WCDMA at lower

running costs while going for LTE

Nokia SRAN : • Common/ Shared HW:

Radio and Baseband

• Single SRAN SW Release

• Common O&M & transport

2 cabinets & 12 radios

3 separate basebands

GSM with TDM; IP for

WCDMA and LTE

4 radios and common baseband, all-IP

SRAN simplifies networks

Less complexity: common & shared HW

Simpler operations: common SW and OAM

Lower TCO: OPEX savings
