The conference also marks the start of a month-long public consultation giving internet users the chance to have their say on how £21million of government cash should be spent improving broadband.
So far, more than 7,000 households and businesses have joined the campaign for superfast connections.
Guests including Suffolk MPs, business leaders and council officials will be there, and students from Ipswich's Copleston High School will give a demonstration on beneficial broadband is to their education.
Connection speeds in Suffolk vary hugely, with some rural areas enduring speeds as low as 0.5Mbps.
Campaigners hope at least 10,000 people will sign up, and that other businesses including internet companies will invest in the Suffolk area.
