Networks were originally designed for one PC per user. There is now a shift in access. Now the primary access method is wireless and that ratio is skewed to 4 to 1 because each employee is demanding access for notebook, tablet, personal phone, and employer issued phone. Quadrupling the demand of network access implies the need for flexible yet scalable wireless infrastructure. Scalability is very important in ensuring a high performing network that drives business productivity.
