At the Huawei User Group Meeting 2018, the company announced the official release of its LTE eRAN13.1 solution. Based on the SingleRAN Pro platform, LTE eRAN13.1 enables operators to develop a multitude of services on a single network.
In addition to providing higher bandwidth for individual users, operators will be able to cultivate services such as the Internet of Things (IoT) and low-latency services to help build future-oriented all business connected LTE networks.
The past decade has witnessed the growth of the mobile Internet, leading with a focus on a human-centered digital revolution. Over the next decade, the mobile Internet will continue to rapidly develop and bring with it new opportunities and challenges. As new types of services begin to emerge, a mobile network is expected to host multiple services on a unified hardware platform. Therefore, the capability of the software becomes increasingly important. LTE eRAN13.1 is specifically designed as a future-proof solution and supports network evolution with four core benefits: larger capacity, more spectrum, better IoT, and lower latency.
eRAN13.1 is also the first version to include FDD Massive MIMO. This version offers triple capacity gains and provides users with a high-speed experience during heavy urban traffic scenarios in central business districts. The solution also benefits from innovations such as CloudAIR2.0. This allows operators to acquire additional spectrum (spectrum resource cloudification), while helping to realize an agile network architecture. GSM/UMTS and LTE spectrum sharing helps operators maximize spectral efficiency and achieve fast and flexible technological advancement.
Better IoT is achieved by CIoT 2.0. LTE IoT technology (represented by NB-IoT and eMTC), is a 5G-oriented IoT technology recognized by 3GPP. It has been used by an increasingly diverse list of operators that aim to explore new services across various vertical industries. LTE eRAN13.1 expands the length, breadth, and depth of applications for vertical industries and wins operators more business opportunities by further improving rates, coverage, capacity, and positioning capabilities.
Lower latency is an effective tool to help promote accelerated applications. The air interface acceleration function of the eRAN13.1 reduces application latency and improves user experience. As test results indicate, the average latency decreases from 110 ms to 87.5 ms in heavy-load scenarios and 75.8 ms to 64.3 ms in medium-load scenarios. Meanwhile, the stability has been enhanced for better user experience. The data suggests that the proportion of latency that lasts longer than 100 ms is reduced by a factor of 50%.
In addition, LTE eRAN13.1 further improves upon basic performance, including the multi-carrier network performance, downlink/uplink user-perceived rate at cell edges, and VoLTE quality. These combined efforts will help operators to build an all business connected LTE network, complete with an optimal user experience.
Chen Chuanfei, Vice President of Huawei LTE Product Line, said, “In order to build a smart digital world with things being increasingly connected, the network must be both powerful and flexible. Based on a powerful, unified hardware platform, Huawei has been relentlessly working towards greater software innovation, in terms of coverage, capacity, latency, intelligent O&M, continuous evolution, and a wide range of other related aspects. LTE eRAN13.1 is Huawei’s latest achievement to assist operators in tackling the modern challenges of the new network era.”
