BARCELONA -- Mobile World Congress -- SDN and NFV, followed closely by the Internet of Things and 5G, are slated to be the biggest topics of discussion when the doors to the Fira officially open tomorrow for Mobile World Congress (although seasoned veterans know the show actually starts today, Sunday).
Nine hundred of you voted in our poll, asking, "What will be the hottest topic at Mobile World Congress 2015?" which is just 1% of the number of people who attend MWC, but is still a good sample size to get a feel for the show's biggest trends. SDN and NFV were the top choice, garnering 19% of the vote, followed by 5G at 16% and the IoT at 15%. (See MWC: Let the Madness Begin.)
Although not capturing as much buzz, VoLTE (9%), LTE-Unlicensed (8%), small cells (8%), network security (7%), analytics (5%) and C-RAN (3%) all got some votes as well. And, as is true with any trade show, some people are just in it for the food. Nearly 10% of respondents selected tapas as the hottest topic at the show, or maybe just in the city. (See Hola, MWC#15.)

Light Reading's team of ace reporters will find out if our readers' predictions come true this week and will report back on the progress made around SDN and NFV, if IoT demos trump those of the Consumer Electronics show, if any consensus is reached amongst the hype around 5G (expect some 4.5G and pre-5G in there too) and more.
