Altiostar was started by the founders of Starent Networks, a startup bought by Cisco in 2009.[6] Altiostar came out of stealth mode in late 2014 after raising $70 million in funding starting in 2012.[7] The company's initial offering was a virtualized Cloud-RAN (C-RAN) solution that connected radios with controllers with Ethernet, instead of dark fiber.[8] In 2015, the company introduced a virtual radio access network (vRAN) product.[9] In 2017, Altiostar released an Open vRAN Development Platform, allowing independent radio equipment manufacturers to develop a vRAN solution utilizing Altiostar technology.[10] Since its debut, the company has raised $357.5 million from Cisco, Rakuten Mobile, Qualcomm Ventures, Telefonica and Tech Mahindra among others.[11]
