The average person looking at the upper corner of their phone might ask themselves, “what is 4G LTE?” or “what is LTE data?”

LTE stands for “Long-Term Evolution.” It’s often conflated with 4G LTE, the fourth generation of global wireless communication and data transmission.

LTE is one of the fastest-developing mobile technologies and connects one in four mobile users globally. Although it is not the same as 4G, the two technologies are vital to Internet of Things (IoT) enablement.

The Evolution of Cellular LTE Technology

The first generation (1G) of mobile technology emerged in the 1980s with analog voice. Eventually, it was supplanted by 2G and 3G networks.

Today, mobile network operators (MNOs) have fully established their global LTE rollouts of 4G networks. They have used these networks to transition from 2G and 3G generations to LTE.

The Rise of LTE

Since its commercial launch in 2010, LTE has been pivotal to 4G adoption. However, this paradigm was not always the case.

4G began with LTE and Worldwide Interoperability for Microwave Access (WiMAX). These competing systems were on the Orthogonal Frequency Division on Multiple Access (OFDMA) modulation scheme. In the end, LTE dominated the broadband market and spread across verticals.

Decoding the Semantics

For clarification, experts often say “4G LTE” to delineate between 3G’s and 4G’s capabilities. LTE represents a gradual shift toward the 4G standard. 

5G and LTE

Despite the hype behind 5G, it will not replace 4G soon. 4G LTE networks will continue to serve as a leading mainstream mobile technology, as 5G networks will depend on it.

How Does LTE Support IoT?

IoT constitutes a network of real-world objects that use sensors to collect and exchange data with other devices via the internet. IoT devices can be small, like virtual home assistants, or massive, like factory machinery.

There are over 13 billion IoT devices today. Sustaining large-scale, high-speed connection deployments requires considerable bandwidth. LTE provides a reliable connection for IoT devices to complete data transfers to the cloud and other devices.

One of the important things this technology also provides is the ability for cellular LPWA networks (e.g., Cat M and NB-IoT) to run on its infrastructure. (Enabling this ability requires some dedicated development on the LTE network.) In many use cases, Cat M and NB-IoT are the most suitable technologies for IoT applications.

Use Cases and Benefits

LTE IoT enables electric vehicle charging stations.

LTE IoT devices have a well-established presence in many machines and equipment, such as:

  • Electric vehicle charging stations
  • Health monitoring gadgets
  • Home and commercial security

Cost reduction drives these devices, as this technology is more spectrally efficient and flexible than its predecessors. Also, IoT data is transported faster over 4G LTE networks at a lower cost per bit.

Moreover, LTE IoT devices are future-proof and fully compatible with the fast-arriving 5G paradigm shift.

LTE是什么,如何在物联网中使用?
普通人看到手机顶部角落显示“4G LTE”或“LTE数据”时,可能会自问:“什么是4G LTE?” 或者 “什么是LTE数据?” LTE是“Long-Term Evolution”(长期演进)的缩写。它常与4G LTE混为一谈,而4G LTE是全球无线通信和数据传输的第四代技术。LTE是发展最快的移动技术之一,连接着全球四分之一的移动用户。虽然它与4G并不完全相同,但两者在物联网(IoT)实现方面都至关重要。**蜂窝LTE技术的演进**第一代(1G)移动技术于20世纪80年代出现,采用模拟语音。随后,2G和3G网络取代了1G。如今,移动网络运营商(MNOs)已经在全球范围内全面部署了4G LTE网络。他们利用这些网络从2G和3G时代过渡到LTE时代。**LTE的兴起**自从2010年商用推出以来,LTE在4G的应用中起到了关键作用。然而,这一格局并非始终如此。4G最初包括LTE和WiMAX(无线宽带接入)。这两种竞争系统都基于正交频分多址(OFDMA)调制方案。最终,LTE在宽带市场中胜出,并扩展到多个领域。**语义解析**为明确区分,专家们通常会说“4G LTE”,以区分3G和4G的能力。LTE代表了向4G标准的逐步过渡。**5G与LTE**尽管5G受到大量宣传,但它不会很快取代4G。4G LTE网络仍将继续作为主流移动技术,因为5G网络也将依赖于它。**LTE如何支持物联网?**物联网是由现实世界中的物体组成的网络,这些物体通过传感器收集和交换数据。物联网设备可以很小,如虚拟家庭助手,也可以很大,如工厂设备。目前全球已有超过130亿个物联网设备。要维持大规模高速连接部署,需要大量的带宽。LTE为物联网设备提供了可靠的连接,从而完成数据传输到云和其他设备的任务。此外,LTE还为蜂窝LPWA网络(例如Cat M和NB-IoT)提供运行其基础设施的能力。这需要在LTE网络上进行一些专门的开发。在许多应用场景中,Cat M和NB-IoT是最适合物联网应用的技术。**应用场景与优势**LTE物联网设备已经广泛应用于各种设备和机器中,例如:- 电动汽车充电站 - 健康监测设备 - 家庭和商业安全系统 成本降低是驱动这些设备普及的重要因素,因为与前代技术相比,这项技术具有更高的频谱效率和灵活性。此外,物联网数据在4G LTE网络上传输速度更快且每比特成本更低。更重要的是,LTE物联网设备具备面向未来的特性,并且完全兼容即将到来的5G范式转变。**全球物联网部署的解决方案**我们的LTE解决方案组合连接各种本地、多地区和全球范围的部署,并增强以市场领先的连接管理平台。我们能够以高效且无差错的方式提供多IMSI功能和基于嵌入式SIM(eSIM)技术的物联网连接计划。LTE计划可以根据不同维度,如以下情况进行定制:- 低数据速率(通过LTE-M和NB-IoT) - 超低功耗支持(通过PSM和eDRX) - 移动宽带 我们的物联网连接计划和SIM卡能够克服小型或大型工业部署中的各种挑战。**与物联网专家交流,获取您的物联网连接入门套件。** **请求入门套件**
