Our embedded antenna solutions and related design and test services, which has historically been our core business, is predominant to our consumer market, but also is a significant component of our enterprise market, and to a lesser extent, automotive markets. In delivering embedded antenna solutions our design teams partner with customers from the early stages of antenna prototyping to device throughput testing to facilitate optimal performance and quick time to market. Our capabilities include design, custom engineering support, integration, and over-the-air, or OTA, testing. These capabilities have resulted in a strong reputation across the OEM, ODM and chipset manufacturer ecosystem. Our competencies and strengths have helped us secure design wins used in multiple reference designs from leading Wi-Fi chipset vendors. OEMs, ODMs, chipset manufacturers and service providers rely on these reference designs and our engineering skills to deliver superior throughput performance. We view our relationships with OEM, ODM, chipset and component manufacturers, and service providers and carriers as an important attribute to our long-term strategy and success. As a wireless connectivity solution provider that has a history in antenna technology, antennas are a part of everything we do, embedded or otherwise.
We have over 1,000 antenna products in our portfolio which shipped worldwide and are implemented across millions of devices. During 2020 we supplied our products to carriers, retailers, OEMs, ODMs and end users in three primary geographic regions: North America, Europe, and Asia Pacific. Our customer base includes Aruba, Cisco, AT&T (DIRECTV U.S., LLC), Belkin International, Inc., Broadcom, Charter Communications, Inc., Comcast Corporation, Commscope, Inc., Dish Network, Liberty Global plc., Nokia, Telefonica SA, Sagemcom SAS, Samsung, Technicolor SA and ZTE Corporation, among others. We have achieved significant growth in our business, and from 2012 to 2020 our annual sales have grown from $18.2 million to as high as $60.6 million in 2018.
Our embedded and external antenna solutions support a variety of wireless access technologies across the licensed and unlicensed spectrum of frequency bands. These include IEEE 802.11 a/b/g/n, 802.11ac and ax (now calledWi-Fi6), 3G, LTE, 5G, low power wide area (or LPWA), as well as wireless internet of things, or IoT, standards such as Bluetooth, ZigBee and Z-Wave, among others. In addition, we have expertise in the testing and benchmarking of passive and active wireless systems and devices includingWi-Fi6 and 5G cellular. To satisfy the rapidly evolving technology needs of the industry, we have remained on the leading edge of next generation development by aligning ourselves with the evolution of wireless standards and working with wireless chipset vendors and our OEM partners on proof-of-concept and reference designs from very early in the new product development cycle, ensuring our solutions are ready in advance or in time for customer product implementations of new technology.
