Products

Realtek manufactures and sells a wide variety of products throughout the world, and its product lines can be broadly categorized into two subdivisions: Communications Network ICs, and Computer Peripheral and Multimedia ICs. Included among the communications network IC products manufactured and provided by Realtek are: network interface controllers (both the traditional 10/100M Ethernet

It seems clear that Realtek has been setting its eye on pursuing the Holy Grail of the anticipated new applications and needs derived from the concept of Digital home proposed by Intel.
The Realtek is also a main supplier of B/G/N wifi module for the US based wifi adapter manufacturer UAWIFI. The company decided to use RTL8188 board in their new high end wifi adapter UA3 as it is the most reliable and powerful adapter on the market.

Awards

Realtek's single-chip fast ethernet controller, the RTL8139, receives "Best Component" and "Best of Show" awards at Computex-Taipei '97. Seven years later, its dual-band triple-mode WLAN solutions, which includes a baseband processor/media access controller RTL8185L and an RF chip RTL8255, again receive “Best Choice of Computex” award at Computex-Taipei 2004.
