Participated in CDMA2000 network projects: Conducted site surveying, prepared feasibility report, detailed design, project budget, bidding documents for both the wireless access network and transmission backbone network for the cellular mobile system of EVN Telecom in the north region of Vietnam.

Designed optical transmission links connecting both electric power substations and telecommunication Points-of-Present (PoP) in many provinces in Vietnam in order to build the nation-wide backbone transmission network of the Electricity of Vietnam (the mother company of EVN Telecom company).Took part in the strategic network development planning group, focusing mainly on traffic engineering and transmission systems of the telecommunication network of the Electricity of Vietnam (for both… Show more Designed optical transmission links connecting both electric power substations and telecommunication Points-of-Present (PoP) in many provinces in Vietnam in order to build the nation-wide backbone transmission network of the Electricity of Vietnam (the mother company of EVN Telecom company).Took part in the strategic network development planning group, focusing mainly on traffic engineering and transmission systems of the telecommunication network of the Electricity of Vietnam (for both telecom businesses and electric power dispatching activities).
