Wireless communication standard setters why the 5G is overrated

When discussing the Internet communication technologies, the industry association for such a cliché topic:

Internet communication technology so much, the need for a uniform standard?

5G there are so many advantages, it is required for Internet communication technologies?

Networking area this is one of the few problems with transmission, specifically has been sublimated into two propositions. Industry have given their answer to first question, benevolent; the second is almost unanimously, they think that 5 g is the basis of all things Internet.

But in the eyes of a wireless communication standard custom, the answer is the opposite. Wi-SUN Union greater standards Director, IEEE 802.11 (WiFi), 802.15 wireless professional networking and Zigbee Alliance founder Robert Heile received from Lei feng’s network (search for “Lei feng’s network”, public interest) interview, has overturned the two propositions.

5G is not the only

If you use the simplest way to describe differences in networking and the Internet, it is “a large quantity”.

By 2020 there will be 26 billion devices will achieve interoperability, in fact it could be bigger.

Heile said.

This order of magnitude to make high demands to make the connection between the device and even standards haven’t developed was deified 5G network has been in the industry become a key technology for hosting such a large-scale equipment. From a technical standpoint of choice for 5G is the Internet of things, and it supports large-scale data connections, and has the advantage of high bandwidth, high speed and low latency.

However, Heile, 5G role was amplified by industry, it is not the only communication technology.

Although 5G will become the core of future networks, but also key to the mass adoption of the Internet of things technologies, but the 4G extension only, not a revolutionary technology, even without 5G, things still exist.

You may think so, five years after commercial 5G field is still the mobile Internet, rather than the Internet.

Because in the tens of billions of Internet devices, bandwidth scenarios and data traffic is only a small part of it.

Take a very simple example, you deploy sensors of the building façade cannot also implanted a 5G module, power consumption and cost is obviously not allowed. Instead there is some near-field communication technology such as Bluetooth, Zigbee, and even SigFox, LoRa and other low power private networks can also solve basic communication between devices.

Summary is, 5G is just part of a wider network of Internet of things.

Compatibility, there is no uniform standard

No doubt, WiFi, and Bluetooth, ZigBee, Zwave, and numerous is not mainstream wireless communications technology can satisfy the needs of various scenarios. For example, the short-range high-speed application you first think of WiF, point-to-point distance transmission using Bluetooth to meet …

But communication protocols but sweet annoyance.

Now the biggest problem is too much technology over the next five years will be phased out, and several mainstream technologies.

As to what kind of technology will become mainstream who dare to make improper comments, however, Heile also made a bold prediction–there can be no uniform standard between communication protocols also do not replace each other.

Wireless communication and cable are not the same, because the causes of air interface, direct connectivity of wireless communication is not possible, and the different communications protocols have different application scenarios, technologies cannot meet the tens of billions of devices.

This logic seems correct, but the chip-makers, module suppliers and terminal equipment manufacturers to bring a difficult question–among the many technologies to choose the most appropriate technology is not difficult, but the technology you pick what technology to connect with others is a skilled task.

At present, the tradeoff is between the various devices in the industry can not directly connected, for example, within the family, through a gateway device can be connected to different communication standards, greater range, can also be solved through the clouds.

In this regard, Heile thinks just to Exchange data, is equivalent to connectivity. KENZO iPhone 6 Plus Case

Is the nature of Internet connected devices, but the purpose of connecting devices can exchange data, and converting data into usable information. From a technical perspective, networking at any level if it can be connected to each other, enabling data transfer, you can become part of the Internet of things, such as WiFi or cellular networks (mobile network).

Of course, Heile says this is the best of several connection methods, better plan ahead, like many Union are pursuing compatible technology.

The ultimate goal

From a single technology, applied to the Internet communication technology and there will be no big change in the future, the most likely scenario is to be developed to a higher standard of standards development, such as frequency, reaching dozens of GHz, so you can reach higher speeds and higher bandwidth. At present, the industry has been done in optical communication, so there is not much in frequency space.

Frequency has reached the limit, but the new technology is still emerging.

For example, in recent years the attention of the industry “multi-hop networks”. It is constructed from nodes, including devices such as computers and cell phones, these devices are wireless connected to each other, and can transmit data over the network to each other. Data from one node to another node until you reach the destination. As soon as any one node is available, data can be transferred.

Wireless Ad Hoc networks, wireless sensor networks and Wireless Mesh Networks fall into this category, but the programme is not yet mature. Future wireless communication technologies not only acts as a connection
