He started with a few access points, and used customers as access points for down stream customers until the number of customers justified a dedicated access point / back haul. It speed deployment with little to no impact on usability. <br /><br />In addition, 5G is not a long reach technology. the number of access points required for coverage lends itself to self back hauling. Simplifying installation, and can add redundancy**. <br /><br />As mentioned, the problems are latency, interference, and bandwidth. Latency will limit the number of hops, bandwidth, as the number of users grow. As this becomes an issue, the access point can be upgraded point to point wireless back haul, or fiber.<br /><br />**If one fiber is cut, the system can find a path to another good fiber. Even if every access point is connected to fiber, I recommend self back hauling as a fail-safe, slightly higher latency is better than no connectivity.Stephen Sedio (via 3GPP 5G Standards Linkedin Groups)https://www.linkedin.com/groups/7489690/7489690-6259047615397138433noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-87994874694849748952017-04-16T08:55:14.100+01:002017-04-16T08:55:14.100+01:00applications can be for both FTTx.

If this is achievable, then we are gonna see massive change in the way we design, operate & optimize the xhaul.

If this was done, it should be self-recoverable and self-configurable. Critical part is balancing access/backhaul traffic ratio. Definitely, more Machine Learning and AI in general will be required to achieve it.Miguel Patiño González (Linkedin)https://www.linkedin.com/feed/update/urn:li:activity:6259044351284899840/noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-20043431588488732882017-04-16T08:52:07.906+01:002017-04-16T08:52:07.906+01:00This may also be evaluated for FTTx modem backhau...This may also be evaluated for FTTx modem backhaul as WTTx.The important challange is the capacity management of radio carrier spectrums between MBB and FBB users.I know one vendor has an WTTx solution which can also be used in LTE right know.Fatih Pazarlıoğlu (Linkedin)https://www.linkedin.com/feed/update/urn:li:activity:6259044351284899840/noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-74253360238035636262017-04-16T08:50:55.500+01:002017-04-16T08:50:55.500+01:00interesting topic, this was looked at back last ye...interesting topic, this was looked at back last year, in this award-winning paper:<br /> Joint In-Band Backhauling and Interference Mitigation in 5G Heterogeneous Networks <br /><br /><a href="https://arxiv.org/pdf/1604.02750.pdf" rel="nofollow">https://arxiv.org/pdf/1604.02750.pdf</a>Dr. Mehdi Bennis (Linkedin)https://www.linkedin.com/feed/update/urn:li:activity:6259044351284899840/noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-35521033718187657862017-04-16T08:49:33.309+01:002017-04-16T08:49:33.309+01:00I believe that 5g will be driven by massive small ...I believe that 5g will be driven by massive small cells or unique smart integrated radio equipments which combine traditional antenna,rru and bbu's itself.
