5G Site Solutions Disaggregation using Open RAN

According to Latest Market insights the RAN innovation for Telecom Lags behind others initiative by 7years which means call for more innovative and Disruptive delivery models for the Site solutions specially for next Wave of 5G Solutions .

However to reach the goal of fully distribute and Open RAN there needs to build a pragmatic view of brown fields and finding the Sweet Spot for its introduction and wide adoption .

Here are my latest thoughts on this and how Telecom Operators should adopt it . There is a still a time for industry wide adoption of Open RAN but as yo will find time to act is now .

What you will

What you will learn

• Building Delivery Models for Open RAN in a brownfield
• Understand what,when and how of Open RAN
• What is Open RAN and its relation with 5G
• Current Industry solutions
• Define phases of Open RAN delivery
• Present and Next Steps 5. Architecture and State of Play

Australia continues to innovate 5G with Applications and Industry

How 5G will change the Geo maps and Economy in the Post Covid-19 world , some key initiatives we learn from Australia 5G Ramp

1. Australian Federal Govt to invest more than $21M to boost use of industrial use of 5G across Australia

2. The Key industry Govt want to harness through this grant are agriculture mining, logistics and manufacturing.

3. Attracting top talent in development is key target as 5G comes to life with 1/3 of Aussies already covered by 5G

4. More than $8.1M will improve Spectrum including adoption of DSS and launch of Ku band 26GHz

5. Government plan at least 1GHZ Spectrum availability for uRLCC (Above 279MHZ in US and 300 MHZ in West Europe)

6. Government Smart rollout initiatives plan to increase 5G throughput from 300Mbps to above 1Gbps by 2021+

With Iphone 5G launching this month I am optimistic in all sense AUstralis will keep on as one of leading markets for 5G

Top Considerations to build a Future Transport for 5G Networks

source: NEC Future Networks

According to latest reports from leading Trasnport Infrastructure vendors Ericsson and NEC . it is very vital to build Next Era Transport for 5G that can serve for MPLS and SRV6 end to end . When we think of future business cases like End to End Network Slicing it will become for important .

These are

Transport for Open/C-RAN

As 5G will deploy in different scnerios and Cloud will be long term most lucrative one so transport must align with it by offering Packet and Ethernet based transport end to end from device to core preferably using e-cpri models that has significant low latency

Outdoor Dense Urban solutions

In Outdoor in city centers laying NG Fiber may not be feasible solution so offering connectivity using PON and MW is needed that is why it is important to not just lock with Fiber solutions

Automation of Transport

Just like others domains like RAN , Core , Edge the transport also need to be Orchestrated and must be optimized over time using ML and AI . the key for this is build a transport that can automate using T-SDN like ACTL workflows or Open ROADM and that can help collect all data that can be optimized with AI .Cool stuff

Future DC architectures

Transport should be flexible not only to offer transport based on 3GPP service model but based on DC architectures like solutions for Clos architecture , DIs-aggregated scnerios etc

Distributed architectures

Just like with other solutions in 5G the transport should be distributed like support for Hub /Be-spoke rather than full mesh for both reliability , performance and scale .

Secure architectures

Security nevertheless is of paramount importance specially as we will open transport for 3rd party and whole sale connectivity although this domain is well addressed in Orchestration and End to End Slicing however as famous adage we must be leave the software boundary un attended .

“Protecting a software with another software in a cloud is not scalable.”

Cyber Security for 5G and Cloud World

Cisco Latest report quantifies in 2019 1272 breaches that exposed 163M customer records . In a 5G and Cloud connected world to adress security concerns 5G Security SA5 and community defined some key principles that we must adhere to build dis-aggregated Networks .

1. Use of SUCI (Subscription concealed Identifier) to ensure even during first Latch the subscriber ID is not sent as plain test

2. 5G Auth and Key Agreement uses private/public key something very familiar to Cloud hyperscalers to grant resource access

3. Before device join network the Core will validate device then the device authentication start (This architecture make use of AMF ,UDM and AUSF and SEAF)

4. Use of Network Slicing in NPN and Public NW to ensure only users can reach his service slice only

5. To solve issues that limit operators use of encryption on Iu interface is addressed in 5G with the use of Data validation to ensure even protected streams can have integrity check

6. The New SecGW (Security end point GW) to tunnel the Radio GnB traffic directly at access/metro

7. API and Digest level protection for MEC and Developer system combined with security DDoS ,Malware protection

8. IdM and HSM for Infra security
