What Tescom does
Tescom Co., Ltd. is a South Korea-based designer and manufacturer of wireless communication testing equipment, founded in 1993 and headquartered in Goyang-si, Gyeonggi-do. The company specializes in RF test and measurement solutions spanning the full product lifecycle from R&D to mass production, with a portfolio that includes RF shield boxes (5G mmWave, Sub-6GHz & UWB, and Audio variants), OTA chambers, TEM/GTEM cells for EMC/EMI testing, multi-protocol connectivity testers (WLAN/Bluetooth/ZigBee), Bluetooth audio testers, GNSS signal generators, antenna measurement systems, RF couplers, and filtered I/O interfaces. Its technology stack supports 5G mmWave up to 67 GHz, Sub-6 GHz, Bluetooth v5.3, WiFi 6E, UWB, GNSS, and MIMO, with proprietary SDR-based tester architecture enabling software-only upgrades for emerging wireless standards.
The company generates revenue primarily through build-to-order hardware sales priced via custom quotation, with 4-8 week lead times, supplemented by calibration, warranty/repair, on-site service, and custom fixture/automation integration services. Its go-to-market combines direct field sales through six wholly-owned regional offices (Korea, USA, China, Taiwan, India, Vietnam) with a network of channel distributors covering the UK, Denmark, Japan, and additional regions. Customer segments span consumer electronics manufacturers (smartphones, tablets, modules), automotive electronics (telematics, AVN, wBMS), IoT device makers, medical device OEMs, and audio device manufacturers. Notable reference customers include Nordic Semiconductor and Doosan Corporation Electro-Materials, with a strategic 2022 MOU with Anritsu positioning Tescom within the broader communications test ecosystem. The company operates ISO-9001 certified quality systems, holds multiple Korean government innovation awards, and employs 11-50 people across its global footprint.
