BLE is a fast growing market. This market grew from almost nothing in 2012 to close to 165 million units by 2014. It is expected to grow to 1.2 billion units by 2018. Also, every new smartphone is Bluetooth Smart Ready. 61% of the ICs sold into modules in 2014. Why such a large shipment into modules? The reason is, customers prefer modules because they shorten the design cycle by eliminating RF design on the board. Customers have to face no isolation issues, antenna issues, or RF interference issues. Customers also would not need to do Bluetooth qualification, because it is already done by the module supplier. In addition, customers do not need to buy expensive equipment at the factories for RF testing. In reality, the small size integrated modules are driving the growth of BLE-enabled solutions in the market. The picture here shows Cypress and other BLE modules in the market. Several RF applications use BLE modules to get smartphone connectivity or I/O capabilities into one’s solution.
