Meru Networks was a supplier of wireless local area networks (WLANs) to healthcare, enterprise, hospitality, K-12 education, higher education, and other markets. Founded in 2002 and headquartered in Sunnyvale, California, United States, the company made its initial public offering in March 2010.

Meru Networks was founded in 2002 to address issues with legacy wireless networking architectures that support two separate access networks: a wired network for business-specific applications and a wireless network for casual use. This causes problems ranging from co-channel interference to the inability of micro-cellular systems to scale up. Meru Networks develops and markets a virtualized wireless LAN solution that enables enterprises to migrate applications from wired networks to wireless networks and become what Meru refers to as the "All-wireless enterprise." The company uses an approach to wireless networking that employs virtualization technology to create a self-monitoring wireless network that provides access to applications, improved application performance, and a greater ability to run converged applications, such as voice, video and data, over a wireless network.

The company’s current products address the IEEE 802.11ac and 802.11n wireless networking standards, The company focuses on a “Virtual Cell” approach to Wi-Fi. Under a single service assurance platform, it aggregates access points and the controller needed to manage them. This simplifies the management of access points, cuts the number of access points needed on a wireless network, and eliminates bandwidth contention issues.

Products and services are sold through value-added resellers (VARs) and distributors.
