Speakers’ Biographies
Dr. Eddy Chiu is a Senior Engineer at ASTRI. His research interests covers 1) 5G wireless
communication technologies (e.g., massive MIMO schemes, mmWave systems, dense
cellular systems, machine-to-machine communications, device-to-device communications,
cloud radio access network, TV white space, etc.); 2) Long Term Evolution (LTE) and
LTE-Advanced system design and network planning; and 3) Localization technologies (i.e.,
global navigation satellite systems, LTE indoor positioning, and iBeacon).
Eddy received the PhD degree in Electronic and Computer Engineering from the Hong Kong
University of Science and Technology, Hong Kong, and the MASc and BASc (Honors)
degrees in Engineering from Simon Fraser University, Canada.
Dr. Zhang Honglei is a principal engineer at ASTRI. He leads the system team in ASTRI’s
LTE group. His team develops algorithms for LTE small cell, self-organizing networks, and
LTE user equipment. Honglei Zhang received his BS and MS degrees from Xidian
University, and earned his PhD degree from University of Massachusetts Amherst.
Mr. Jesse Ai is a manager at ASTRI, leading the multicore-based networking protocol stacks
software (known as FastGate) R&D. FastGate provides key data plane software platform to
build 4G and beyond network infrastructure equipment with high performance and
scalability. He is currently focusing on designing next generation networking software by
leveraging Software Defined Networking (SDN) and Network Function Virtualization (NFV).
Jesse has more than 12 years of experience in the telecommunications industry in various
software product development and design. He has solid expertise and experience in
networking, software performance optimization, OS kernel, and IP networking protocol
stack. Prior to joining ASTRI, he worked in major telecom companies like UTStarcom
involving implementation and performance optimization of BSS/OSS software of mobile core
network. Jesse is also a contributor of OPNFV project for VNF Data Plane Acceleration (https://wiki.opnfv.org/dpacc).
Abstracts
1. Radio Access Technologies for Next Generation Networks by Dr. Eddy Chiu
The proliferation of wireless broadband usage has created high demand for next generation networks (NGN) that can
efficiently support new and better services. In this talk, we will present ASTRI’s research in two key radio access
technologies for NGN, namely, Cloud Radio Access Network (C-RAN) and LTE Device-to-Device (D2D)
communications. C-RAN is a centralized, cloud based new cellular network architecture that can be adopted by
telecom operators to improve their quality of service with reduced capital expenditures (CAPEX), operating
expenditure (OPEX), and energy consumption. LTE D2D is a new technology that allows terminals to discover and
directly communicate with each other for public safety networking and smart city applications.
2. LTE Machine Type Communications for Internet of Things (IoT) by Dr. Honglei Zhang
Machine Type Communications (MTC) refers to automatic information exchange between devices without human
intervention. MTC is one of key enabling technologies in the Next Generation Networks (NGN) for Internet of Things
(IoT) applications such as smart city, health monitoring, and supply chain tracking and tracing. Due to essential
differences between MTC and conventional communications, 3GPP is optimizing the LTE standards for MTC. In this
talk, we will present the major issues that the standardization body is addressing to make LTE networks competitive for
MTC/IoT applications. These include cost reduction and power reduction for terminal devices, network coverage
extension, support of massive number of devices per base station, and diverse traffic requirements. In addition,
ASTRI’s R&D effort in LTE MTC will be introduced.
3. Network Virtualization by Mr. Jesse Ai
Network Virtualization is getting much attention by mobile operators. Network Virtualization will transform mobile
network infrastructure, from dedicated hardware and network equipment into a cloud based system built by general
purpose equipment. It offers significant flexibility to provision the infrastructure with different services including 4G,
WiFi, and next generation services. Also, it reduces capital expenditure (CapEx) and operational expenditure (OpEx).
In this talk, several key technologies and concepts will be introduced: Network Function Virtualization (NFV), Software
Defined Networking (SDN), and orchestration. Technical challenges such as system/network architecture,
performance, and management will also be discussed.
