Jerome Henry is Technical Marketing Engineer at Cisco, focusing on Wi-Fi products. Jerome has more than 12 year experience teaching technical Cisco courses and products in more than 15 different countries and 4 different languages, to audiences ranging from Bachelor degree students to networking professionals and Cisco internal system engineers. Focusing on his wireless experience, Jerome joined Cisco at the beginning of 2013. Before that time, he was consulting and teaching Heterogeneous Networks and Wireless Integration with the European Airespace team, which was later acquired by Cisco to become their main wireless solution. He then became technology leader at a Cisco Learning and Solution Partner before joining Cisco. He is certified wireless networking expert (CWNE #45), CCIE Wireless (#24750), CCNP Wireless, developed several Cisco courses focusing on wireless topics (IUWNE, IUWMS, IUWVN, CUWSS, IAUWS, LBS, CWMN lab guide, etc.) and authored several Wireless books (IUWMS, CUWSS Quick Reference, etc.). Jerome was also elevated to the grade of IEEE 802.11 group Senior Member. With more than 10000 hours in the classroom, Jerome was awarded the IT Training Award best Instructor silver medal in 2009.
