许多人在网上反响自己家的wifi时快时慢的,但是却不知道是什么原因,本次,4g路由器厂家将与我们分享WiFi时快时慢的原因是什么?
接下来,4g路由器厂家认为,WiFi时快时慢的原因有以下几点:
1、路由器方位
路由器的摆放方位对WiFi信号强度有较大影响。假如将路由器放在墙角落方位,其信号可能就会被墙体阻挡、吸收,信号强度将会大打折扣。4g路由器厂家建议把路由器放在屋子中间且宽阔的地方,减少WiFi信号盲区。
2、Wifi信号拥堵
用户在经过WiFi接入网络的时候,大多使用的是2.4GHz频段的无线波段,周边相同频段的信号发射、接收设音,如手机、无绳电话、微波炉、蓝牙耳机等设音都可能会对Wifi信号产生影响。所以有时候手机上的WiFi信号显示的是满格,实践的WiFi网速却很慢,可能是这些设备影响了WiFi的信号质量。
3、被蹭网
有时看视频忽然卡了,或许下载速度明显下降了,就有可能是被蹭网了。在网页浏览器,输入地址192.168.1.1或192.168.0.1(路由器默许地址请参照说明书),登录路由器管理后台,查看DHCP设备列表,假如有陌生设备,说明被他人蹭网了。存在缺陷
现有的无线连接方法很难超过有线互联网接入形式。

工业4g路由器是一种用于连接两个或以上网络的耐用器件,可将信号仅传送到所需端口。而工业路由器则是专门用于工业领域的数据传输设备。
许多人会把工业路由器和家用路由器弄混,其实两种是不一样的,那么工业4g路由器和家用路由器的区别是什么?跟随4g路由器厂家伊林思来了解。
1、好的转发性能、带机量。工业路由器大部分是用来数据的传输和其他功能,多则上百个,如果要同时满足这么多人的无线上网需求,则对于路由器的转发性能和带机量有很高的要求。家用4g路由器密度低,信号强度小、覆盖范围小、转发性能和带机量有限,如果是在像企业那样的公共场合使用,就会存在严重的应用隐患。
2、路由协议丰富。an全、稳定是企业网络的生命线。在这一点上,普通路由器由于各种协议较少,所以一般都不支持内/外部攻击防御,防止病毒、木马和黑客的侵扰等功能,很难为企业提供多种an全保护。工业级路由器一般具有多项an全服务,拥有更丰富的路由协议,如SNMP、静态路由器、策略路由器、统一管理协议等。
以上就是工业4g路由器和家用路由器的区别是什么?希望能够帮助大家了解!

5G is still in the research stage of technical standards, and in the next few years, 4G will maintain its dominant position and achieve sustained and high-speed development. But 5G is expected to be commercially available by 2020. So today we take a look at 3G, 4G, 5G technology development changes and 5G development trend characteristics.
From 3G to 4G: two in one
4G comes from 3G technology.
In the 3G era, 3GPP has developed FDD technology represented by WCDMA and TDD technology represented by td-scdma respectively.
In the 4G era, as the representative technology of 4G, LTE, one of the important works is to integrate FDD technology and TDD technology, and unify FDD and TDD into a technical specification system for common development, which can be considered as a combination.
The integration of 4G is not only a technical one, but also an organizational one.
In the 3G era, there are two technical specification organizations: 3GPP and 3GPP2. Although the two groups were large and small, they were still competing with each other.
In the 4G era, 3GPP2 could not be maintained and was finally integrated into 3GPP, realizing the unification of technical specification organization in the mobile communication field.
For example, in the 3G era, the big house of 3GPP opened two stovels, respectively cooking FDD and TDD rice, and there is a small house of 3GPP2 next door.Arrived 4G times, 3GPP besides the hearth closes 2 outside for one, still annex the small house of 3GPP2 next door, dimensions expands ceaselessly.
From 4G to 5G: three divisions
After LTE was unified, I thought mobile communication technology could go all the way to the end, but I didn’t expect bifurcation soon appeared.This is also thanks to LTE’s versatility, which allows for not only person-to-person communication, person-to-machine communication, but also device-to-device communication.So while LTE has three features, it even has flexible wireless parameters. But LTE’s advantages are not enough to match the demands of a vast world.
So, starting with the R13 version of LTE, there’s a new branch: NBIOT, or narrow-band Internet of things, for devices with low power consumption, low rates and narrow bandages.
As the name suggests, NBIOT’s narrow band and LTE’s broadband features are two different things. So it was too difficult to integrate the two ends of the ice and fire, and the branching was inevitable.
In the era of 5G, two branches became three. The three branches of 5G are named eMBB, mMTC and URLLC respectively, corresponding to three application scenarios.
EMBB is a higher rate, achieved through greater bandwidth and improved baseband rate, which is a continuous evolution in the LTE mainstream.
MMTC is more terminals and very low power consumption, known as the Internet of things. MMTC is an evolution based on NBIOT.
URLLC is lower latency and higher reliability and is primarily used for Internet of vehicles. URLLC requires very short latency with faster scheduling.
Characteristics of the development trend of 5G
1. The spectrum utilization rate is greatly improved, and the high-frequency spectrum resources are more utilized
At present, the spectrum resources used for mobile communication are very limited, but China’s spectrum resources are allocated to various radio departments in a fixed way, which leads to the uneven utilization of resources and low utilization rate. Compared with 4G networks, 5G spectrum utilization will be greatly improved, and the high frequency resources will be appropriately applied to overcome this serious problem.
2. To support business personalization to a greater extent and provide all-round information services
People’s demand for mobile communication tends to be personalized and hierarchical. They can leave the communication network all the time in their lives. One of the goals of 5G is to build a more complete network architecture and improve the ability to support a variety of emerging businesses, so as to create a new communication life for users.
3. Communication speed is greatly improved
With the rapid development of information age, people have higher and higher requirements on the rate of obtaining information, which is a great challenge to the transmission rate of communication network. The theoretical data transmission rate of 5G network is 100 times that of 4G standard. 4G has a maximum peak speed of 1G, while 5G can reach 10G. This means that, on 5G networks, an ultra-high-definition movie can be downloaded in less than a second. At the same time, 5G network in the transmission will also present low delay, high reliability, low power consumption and other characteristics.
4. Energy conservation
In 5G network, effective green and energy-saving technologies will be adopted to reduce network losses and control energy consumption within a certain range while ensuring communication quality. In the future communication process, operators can adjust the distribution of resources according to the real-time communication conditions, so as to save the network energy.
At present, the research of 5G is still in the early stage, and there are still many technical problems to be solved. With the continuous deepening of its research process, 5G will inevitably bring new communication experience to users in the future and comprehensively promote the development of the information age.

There are many types of 4G industrial routers, which can be divided into different categories from different perspectives. Different types of 4G industrial routers can be used in different environments. The following sections classify the 4G industrial routers from different perspectives.
According to the performance
From the perspective of performance, 4G industrial routers can be divided into linear router and non-linear router.
The so-called wire speed router can transmit freely according to the transmission medium bandwidth, basically without discontinuity and delay. The specific calculation method is the same as that of the switch line speed backplane bandwidth. A wire-speed router is a high-end router with very high port bandwidth and data forwarding capability that forwards packets at the media rate.
Non-wire-speed routers are mid – to low-end routers, but some new wire-access routers also have wire-speed capabilities. The performance of router is mainly affected by CPU performance. If the CPU performance is high, the 4G industrial router is more likely to be a high-performing wire-speed router.
Speed is generally not a measure of a router, and data throughput is one of the references used to measure a router’s maximum data throughput. The routers with the capacity of the rear plates of 4G industrial routers greater than 40Gbps are called high-grade routers. The routers with the capacity of the rear plates between 25Gbps and 40Gbps are called midrange routers, while those with the capacity lower than 25Gbps are considered as low-grade routers. This kind of dividing way is not so absolute, specific parameter needs to make distinguishing according to each manufacturer specific parameter.
According to the structure of the points
The 4G industrial router can be divided into modular router and non-modular router according to the structure Angle.
Modular routing generally only provides basic routing function when leaving the factory. Its interface type and partial extension function are configured according to the actual needs of users. Users can choose corresponding modules according to the network type they need to connect. Different modules can also provide different connectivity and management capabilities. For example, the vast majority of modular routers allow users to choose network interfaces, VPNS, firewalls and other functions, most of which are modular routers.
Routers H685/H700/H720/H750/H820/H820Q/H820QO from E-Lins are all modular router, can meet the requirements from all over the world.
Non-modular routers are mostly low-end routers, which are mostly used in civilian environments. Primarily used to connect small business customers within homes or isps, supporting virtual private network protocols such as SLIP, PPP, PPTP, and IPSec. These protocols to run on each port, such as ADSL will increase home broadband availability, which will increase the burden of accessing routers. In the future, such router ports will run multiple protocols while avoiding the telephone switched network.
According to the function points
The 4G industrial router is divided into general router and special router. The common civilian router is the general router, that is, the router that can normally use the routing function under the general environment, and there is no other special requirement scenario.
The special router optimizes the routing interface, hardware and so on to realize a certain function. For example, the foreign trade special router changes the local IP through the special router, which can also quickly access some foreign trade stations in China, which is more convenient.
According to the interface points
4G industrial routers can support SDH stm-1 interface, SDH stm-4 interface and SDH stm-16 interface. At present, the router supporting SDH stm-64 interface is high-end 4G industrial router. However, other interfaces are relatively weak, among which stm-1 has two types of optical interface and electrical interface. Stm-1 electrical interface is suitable for local situations where the interference signal is weak. The light interface is usually used for stm-4, stm-16 and stm-64.
according to the perspective of the object of use
The 4G industrial routers can be divided into core router (core level), distribution router (enterprise level) and access router (home level) according to the perspective of the object of use.
The core router, which is the router that forwards packets to the host computer in the network (but not between networks), is the key device to realize Interner network interconnection with other levels of routers. Often used by telecom operators or isps. The throughput of core router is larger, and the requirement of speed and reliability is higher. In order to obtain high reliability, the network system generally adopts traditional redundant technology such as hot backup, dual power supply and dual data path, so that the reliability of backbone router is not a problem.
Distributed routers are used to connect multiple logically separate networks because there are many connected objects, the system is relatively simple, and the data traffic is relatively small. In addition to connecting different networks, distribution routers also need to choose smooth and rapid short-cuts to improve the communication speed, reduce the network communication load, save system resources while improving the unimpeded rate, and maximize the benefit of the network system.
The access router is mainly used for network interconnection in the small local area network. It is often used in the case of small area and simple network environment such as home, small enterprise or net bar.
