The company currently focuses on large-scale telecommunications infrastructures, technology development and licensing, and online mapping services. Nokia is also a significant contributor to the mobile telephony industry, having assisted in development of the GSM and LTE standards, and was, for a period, the largest vendor of mobile phones in the world. Nokia's dominance also extended into the smartphone industry through its Symbian platform, but it was soon overshadowed by the growing dominance of Apple's iPhone line and Android devices. Nokia eventually entered into a pact with Microsoft in 2011 to exclusively use its Windows Phone platform on future smartphones.
