Will 5G smartphones support 10Gb/s Downloads?


Planning for 5G is well afoot, with Mobile Network Operators (MNOs) already taking 5G into thought as they creator new network builds. Ciena’s resident skilled, Brian LavallĂ©e, talks 5G rollouts and the way final success can rely MNOs ensuring that they need fiber in situ for the huge information measure will increase that ar certain to come back as 5G comes on-line.
I keep hearing that 5G would require several tiny cells. Why is that?

Brian:  Higher frequencies expected to be utilized by 5G don't travel as way as lower frequencies used nowadays, and even have a tougher time penetrating walls, bridges, trees, or something physical. to induce around that, MNOs can deploy additional cells that cowl smaller areas serving fewer folks albeit at a lot of higher speeds, which is able to drive the proliferation of tiny cells.

Will 5G smartphones support 10Gb/s?

Brian: at first, in all probability not. 5G is anticipated to support a minimum of a minimum of 100Mb/s nonetheless be capable of speeds as high as 10Gb/s. The mobile infrastructure won’t be able to support many several folks accessing the network at this high speed, a minimum of ahead of time and this is often fine in most things. Today, for instance, observation video is that the most bandwidth-intensive smartphone application, however it doesn’t consume anyplace close to 10Gb/s as a result of there ar solely such a lot of pixels during a smartphone screen to populate. thereupon information measure, United Nations agency is aware of what future applications are attainable.

Will the marketplace for 5G backhaul services be an equivalent because it is for 4G?

Brian:  In North America nowadays, most 4G MNOs purchase backhaul from third-party service suppliers. This market can doubtless continue for 5G, albeit at a lot of higher rates. i think it'll be more and more done mistreatment dark fiber instead of packet-optical-based services, a minimum of for the upper supported rates.

Will the web of Things (IoT) generate video traffic?

Brian:  It depends on what you classify as a “thing”. If it includes HD police work camera, for instance, that runs on a cellular network, then yes, and plenty of it. Smaller things, like temperature sensors, can generate way less traffic, however there is also billions of them deployed, therefore it adds up quickly. For the foremost half, the challenge of IoT can doubtless be concerning the amount of individual services, not capability.

What’s driving the spike in mobile video traffic?

Brian: the solution is perhaps right ahead of you! It’s mobile devices with HD cameras for one, that ar feeding content into YouTube and Facebook, which are, successively streamed to mobile devices over anyplace else. once Facebook enabled auto-play on its videos it drove a huge increase in mobile information measure consumption nightlong. alternative sites have replicated this model, therefore I don’t see the trend retardation.

How can 5G amendment the wireline design that presently supports 4G mobile backhaul?

Brian: that may depend upon MNO’s rollout patterns, what percentage users ar on the network, and what limits they’ll assail speeds. nowadays MNOs generally feed a one Gb/s local area network line to a 4G cell sites, of that a mean of 200-300 Mb/s is getting used. With 5G, that very same macro tower may have 10’s to 100’s of Gbps, which is able to need a huge capability upgrades to those towers.

Will fiber readying patterns amendment once 5G is deployed?

Brian:  Direct communication between cells is planned for 5G networks, skipping the association to the packet core where attainable, which might offload a great deal of traffic. Those cells can be wired along directly within the shortest path, however i believe traffic can largely home back to a central location.

Should a service supplier currently progressing to begin a 4G readying hold off till 5G?

Brian: Yes, as there'll be important and long upgrades to the prevailing 4G wireline network that may ease 5G deployments, as before long because the latter technology arrives. There ar several things that MNOs will do nowadays, like deploy additional fiber to tiny and macro cells, that ar compatible with each 4G networks of nowadays, and 5G network of tomorrow.

Will the 5G backbone be physically and just about break away the 4G backbone?

Brian:  Not physically. If, for instance, a service supplier includes a 4G cell and desires to feature 5G radios to it macro towers, they might doubtless find yourself sharing the aggregation and core network back to the info center, maybe over totally different|completely different} wavelengths or different components of the network, L2/L3 VPNs, or Optical VPNs. Rolling out utterly separate networks for each it'd become value preventive  quickly and far tougher to induce to ROI. Some components of the network are just for 5G, and a few shared.

Will there be a relation between 5G and WiFi?

Brian: affirmative. The Heterogeneous Network (HetNet) that's expected to attain the need geographic coverage for 5G can embody a good type of cells like pico, femto, micro, small, and even LAN, that all serve a smaller space than ancient macro cells via spectrum employ. folks can still wish to use LAN to avoid touching their cellular usage caps, with several of these coffee-shop LAN access points being owned  by MNOs.

How can 5G latency be lower if process is being tired the cloud?

Brian: Latency within the case of 5G refers to over-the-air latency, between the user device and therefore the radio access network radio. to scale back overall latency, service suppliers can have to be compelled to place information a lot of nearer to end-users, that is why some MNOs ar considering leasing house at their cell sites to host information and applications for content suppliers, significantly in massive urban centers. Ultimately, the location of knowledge and process are determined by the supported 5G application. The Mobile Edge Computing (MEC) initiative can play a significant role in addressing this necessary challenge.

What impact can 5G wear backhaul networks?

Brian: information received at the 5G radio set during a cell website won’t go anyplace while not fiber. That’s why several massive MNOs ar shopping for massive fiber footprints. They recognize that fiber and its geographic footprint can ultimately dictate the performance and industrial success of their 5G services and applications. 5G can would like fiber, and plenty of it.
