Kiho Lee Email and Phone Number

Dear all,I hope this message finds you well. I wanted to provide an update on my current role as a System Developer in the R&D department. In my capacity, I have been actively engaged in the design and development of L3 (Layer 3) functions for both NSA (Non-Stand Alone) and SA (Stand Alone) configurations.Over the course of my 7 years in the wireless communication field, I have accumulated a wealth of experience and knowledge that has allowed me to excel in various areas:1. L3 Function Design for NSA/SA: Currently, my primary focus is on designing and implementing L3 functions for both NSA and SA scenarios. This involves intricate work in ensuring seamless communication and interoperability between different layers of the network architecture.2. 3GPP Compliance: I am well-versed in navigating and leveraging 3GPP documentation, particularly standards such as TS 38.413 (NGAP), TS 38.423 (XnAP), TS 38.331 (RRC) for 5G, as well as TS 36.413 (S1AP), TS 36.423 (X2AP), TS 36.331 (RRC) for LTE. These documents serve as invaluable references in my design and problem-solving processes.3. Network Synchronization: Additionally, I possess expertise in verifying the synchronization of femtocells and Macros using PTP, based on the IEEE 1588 standard. This ensures a robust and coherent network infrastructure.4. Network Configuration and Management: I am skilled in configuring and managing network connections between femtocells/Macros and the live core network. This experience extends to utilizing CWMP (CPE WAN Management Protocol) for efficient management within a commercial core network.5. Security Implementations: I proficiently establish secure connections through the utilization of IPsec and VLAN. This guarantees the integrity and confidentiality of data flow between femtocells/Macros and the Core.6. Global Collaboration: With a history of providing on-site support to various countries, I have effectively collaborated with local staff to address challenges and find resolutions through productive meetings.I am excited about the continued opportunity to contribute my skills and experience to our team's success. Should you have any questions or require further information, please don't hesitate to reach out.Thank you for your time and consideration.Warm regards,Kevin Kiho Lee
