DESCRIPTION AND HOBBIES
------------------------------------
15+ years working experience in telecom industry, especially mobile communication. Overall end to end experience from
handset to core network, from TACS to TD-LTE, from Motorola to NSN. Focus on performance and optimization in mobile
network/tcpip/wifi/mobile device. Working on ETSI/3GPP specifications over 10 years which the release from pre-phase1
to R10 which cover GSM/GPRS/CS34/EDGE/UMTS/LTE/LTE-A. Expert in Um/UU/eUtra air interface in signaling
troubleshooting and benchmarking. Multiple oversea project and e2e Telecom project experiences, in case bidding, kickoff,
2. management, presentation, enabling, training, IOT, IDT, ATP, FOA, NAL. . Long term lab test and large scale field test/trial
experiences in GSM/GPRS/CS34/EDGE/UMTS/LTE for MII/CMCC/CMRI/CT mainland China.
Be the first to do attitudes, always willing integration new tech/new feature asap. Then make sure the things running
correct and effective. At the same time happy to make things running automatically. Innovation not only in works but
also in live even cross multi field. For examples, innovated TD-LTE dual carrier dual cell indoor coverage which is the fastest
live speed at the time achieved stable 2x80mbps download speed plus 2x20mbps upload speed, 2012. Apply the fastest
access technology plus uplink bias algorithm in PoC optimize project. Integration Google earth into mobile network
optimize service in 2005. Consolidated performance data, configuration data, running status, failure logs, alarms in time
domain. And made optimize service semi-automatic in 2006. Build benchmark methodology for GPRS networks which
apply dumeter, iperf, ethereal/netmon in 2002. Mature stable personality focus on jobs rather than anything else. So i was
busy worked for Motorola 12years. And continue Worked for the TD-LTE project 3years after NSN acquired Moto network
department.
IT hardware fans, assembled compatible PC/XT in very early stage. Until now still have old x86 CPU from
Intel/Cyrix/Idt/AMD. Modified Apple II for the middle school computer training room, because lack of floppy
drive/controller. Also disassembling all the family mobile phone/laptop/TV/electronic for repairing and fan. Manage my
home power system for example designed and build IC quick charger for different type battery cell. Upgraded high efficient
LED lights for power saving and environment. Touch internet very early in mainland China, more than 20 years ago which
means always online learning and working mode. now on thinking cloud technology which running between bare metal
and OS layer can do handover, high availability, cluster mode, loading balance, fault tolerance, high scale and distribution
system. all those cloud properties not only similar telecom running mode but also can do serve each other great. So I build
cloud bed in home which focuses on computing/networking/storage. For examples Apache CloudStack and Ubuntu
OpenStack with MAAS and hybrid disk with array raid0/SSD/SSHD even hadoop try..
