Network Slicing – Test Now, Succeed Later

Network slicing is fundamental to make 5G networks successful. This whitepaper introduces the concept of network slicing and provides an overview of three primary 5G service types and core network functions. It also highlights how operators and network equipment manufacturers (NEMs) can take a lead on the competition by adopting test and measurement solutions available on the market today.

• How 5G is different from previous cellular connectivity generations
• 5G use cases and challenges
• How testing helps meet quality of service expectations




Satellite Synchronization is Critical to 5G Mobile Cellular Network Operation

Synchronization in carrier networks has been in use forever, but because of its elevated role in 5G, it is now getting more attention. Mobile cellular networks must be synchronized so that towers (base stations) with overlapping coverage do not interfere with each other causing dropped calls or service degradation. 3G and 4G mainly needed frequency synchronization, but 5G cellular technology and 4G LTE-TDD require phase synchronization to make the advanced modulations and techniques work without interference when cells overlap.

5G Fronthaul Handbook

The 5G Fronthaul Handbook is a guide to understanding the impact of 5G on transport networks and key test considerations for ensuring reliable performance and high quality of service.

5G technology is touted as an innovation platform that will enhance our connected world. To deliver on this promise, 5G will demand the network supporting it to be as flexible as the services running on it. The following high-level 5G uses cases are well understood and documented by the wireless industry:

• Enhanced Mobile Broadband (eMBB)
• Ultra-Reliable Low Latency Communications (URLLC)
• Massive Machine Type Communication (mMTC)

The big challenge is how to support these use cases on the same network. Much of the trade buzz to date has been centred on 5G-NR (new radio), virtualized core, and mm-Wave spectrum. Receiving far less attention, but equally important as the new radio interface, is the evolution of the transport network connecting 5G nodes that enable the key 5G use cases –simultaneously.
