近年来，蜂窝无线通信有了显著的增长。尽管有这种增长，但世界上很大一部分地区仍然没有宽带连接。使用包括第三代（3G）和第四代（4G）技术的现有蜂窝无线系统，在提供宽带接入方面存在重大挑战。这些问题包括：高资本和运营支出，每用户平均收入（ARPU）低，缺乏负担得起的回程，能源成本因缺乏可靠的电力供应和地理可达性而恶化，包括通行权等问题。这些挑战需要重新思考开发下一代无线系统以连接未连接的世界。移动性不是设计这种系统的主要驱动力，固定的主要宽带接入是最重要的要求。一个简化的基于IP的网络架构，具有动态频谱共享和低成本无线回程，可以为我们所谓的“节俭5G”设定愿景，以连接未连接的用户。
In the recent years, there has been a significant growth of cellular wireless communications. Despite this growth, a large part of the world is still deprived of broadband connectivity. Using existing cellular wireless systems including Third Generation (3G) and Fourth Generation (4G) technology, there are significant challenges in providing broadband access. These include-High capital and operations expenditure with low Average Revenue Per User (ARPU), lack of affordable backhaul, energy cost which is worsened by lack of reliable power supply and geographic accessibility including issues such as right of way. These challenges require a re-thinking on developing next generation wireless system for connecting the unconnected world. Mobility is not a major driver for designing such systems, rather fixed primary broadband access is the most important requirement. A simplified IP based network architecture with dynamic spectrum sharing and a low cost wireless backhaul can set the vision of what we call "Frugal 5G” for connecting the unconnected.
