If 70% of mobile data traffic is generated indoor, would it be more valuable to develop techology to ensure seamingless transition from indoor to outdoor coverage? It will also guarantee VoIP call can be uninterruptedly carried from indoor to outdoor.
>> - Research groups in China and Korea are heads down developing technologies for 5G cellular services expected to switch on in about 2020.
It is surprising that we are not giving China a lot of credits for their contributions in many things. People just think they steal U.S. IP and that is all. If IBM had been in PC business and Lenovo doing what it is doing now, some will claim Lenovo was stealing IBM IPs. Lenovo has fixed what IBM has no clue on how to fix.
I am sure in 5G and other areas, China is making contributions.
@chanj0, that is happening as well but it is primarily at higher layers of the protocol stack. IPv6 adds capability to do session handoffs and there are a number of proprietary handoff technologies. One of the sticking points has been getting the call information out of the traditional telcos fast enough to do an effective handoff, not to mention how to make sure that the cost is being tracked so that carriers can charge for the call. I would dare say that that is the single biggest issue at this point.
I suspect some of this indoor to outdoor traffic will not require carrier handoff per se. I believe carriers may sell large enterprises indoor small cells to bolster their coverage so traffic is just going from the carrier micro to macro cell.
@Rick, femtocells have been available for a while now. I have one here in my house, but I haven't needed it since they updated the cell service in this area. It works OK, but I find it a little irritating that they would meter my usage on a device that uses my network for the backhaul. By default it would even handle calls from my neighbors, although that is configurable by me. I would have left it on anyway except now my wired ISP is making noises about metering traffic. As I said, the complicated part is the accounting. Every one of these guys is trying to protect their revenue streams. On one level I understand it, but it gets irritating when it is done at the expense of new capabilities.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
