    So What's after 4G LTE ?

    Just curious. What's after 4G LTE ? Seems like these new speeds come out every few years or is it now a mature technology ?

    I don't think there is such a thing as "mature technology" . About 15 years ago I had a phone tech. tell me the 56k was as fast as you could get over copper phone lines. I think someday everything will be instantaneous.

    We all started with 1G and 2G, now we are on 4G (fouth generation). I'm excited to see what will come next.

    As for now, some people still call the current LTE "3.9G" since we wouldn't get the full LTE-capable speeds until LTE-A and CA (carrier aggregation), which is currently slowly rolling out.

    Subspace radio? I sometimes see some references to angular vorticity of radio waves (or something like that) as providing an almost unlimited theoretical RF capacity. I chatted with a friend who's an RF engineer and has worked on this. He said that there was a long way between theory and practice. Also, in theory, UWB could change radio as we know it but it would require that everything above 500 MHz be completely reorganized to operate UWB.

    So What's after 4G LTE ?

    Please, let's get the carriers to deploy 3G, 4G, and-or LTE to EVERY one of their sites before they are allowed to roll out anything new! Every carrier has sites and pockets, some rather large, with just 1x, GPRS, or 2G/EDGE around the country. It's time for all that ancient tech to be done away with except for machine-to-machine use.

    Samsung is apparently working on it, and had a bit of a demo at MWC: http://www.samsung.com/global/busine...es-at-mwc-2015

    Wow, 7.5Gbps! I'm ready for that. 1 Gigabyte per second is going to allow for some really large websites.

    I think that the cable industry imagines a day when all of their equipment is hanging from public utility poles connected by wires. They won't need to connect directly to homes, let alone string wires throughout the house.

    Goals of 5G networks are usually something like:

    Significantly faster data speeds: Currently, 4G networks are capable of achieving peak download speeds of one gigabit per second, though in practice it’s never that fast. With 5G, this would increase to 10Gbps.

    Ultra-low latency: “Latency” refers to the time it takes one device to send a packet of data to another device. Currently with 4G, the latency rate is around 50 milliseconds, but 5G will reduce that to about one millisecond. This will be particularly important for industrial applications and driverless cars.

    A more “connected world”: The Internet of Things (wearables, smart home appliances, connected cars) is expected to grow exponentially over the next 10 years, and it will need a network that can accommodate billions of connected devices. Part of the goal behind 5G is to provide that capacity, and also to be able to assign bandwidth depending on the needs of the application and user.

    The coming of 2G technology (digital transmission of voice, Short Messaging Service or"texting") was in the early 1990s in europe and mid 1990s in the USA. Prior to that point, cellular equipment was a novelty in the analog days where it was so heavy that car phones were the norm. The second generation made such phones replace pagers as vital to professionals. The third generation phones introduced in 2003 made it much cheaper to simply drop landlines in most cases. Verizon postpaid still has 16 million basic phones and 9 million 3G phones out of 104 million connections. They are probably the most 4G centric network in the UA. By 2021 they have announced that they want to get rid of 2G and 3G, but some analysts believe they will make the jump much sooner. As of last week their minimum plan is unlimited talk and text and 1GB of data for $50 + taxes and fees. Although as of right now they are not forcing people off the older plans, it is clear that there will be very little incentive to sign up for a Verizon post paid plan unless you have a 4G phone and use some data.

    We might see pCel technology in-between 4G and 5G. But I'm looking forward to seeing what Google and SpaceX do with their low orbit satellites (if they ever get them deployed).

    5G is a term used to describe the forthcoming fifth generation of mobile network technology.
    The main quality of 5G networks compared to 4G will be speed. It's going to be many times quicker than what we have now, and by quite a way.

    The International Telecommunication Union (ITU-R) set standards for 4G connectivity in March of 2008, requiring all services described as 4G to adhere to a set of speed and connection standards. For mobile use, including smartphones and tablets, connection speeds need to have a peak of at least 100 megabits per second, and for more stationary uses such as mobile hotspots, at least 1 gigabit per second.

    In 2008, Sprint Clearwire was the first to ignore the ITU's definition and marketed its WiMAX network as 4G. Two years later, Verizon and MetroPCS followed suit by calling its “Long Term Evolution” LTE system "4G" and, more controversially, T-Mobile advertised its HSPA+ network as 4G as well.

    Because of this onslaught in December of 2010, the ITU decided to clarify its definition to include "evolved 3G technologies" and gave their blessings to the advertisements in place.

    Hence your comment.
