Mainstream routers adopt the 802.11n standard with 150 and 300Mbps data rates. Makers in the high end are directing R&D toward 802.11ac.
- Wireless standard: Products adopt 802.11n with 150 and 300Mbps. Many companies, however, are developing dual-band 2.4 and 5.8GHz units. 3G models are rising as well.
- CPU & chipset: Most releases use 32-bit RISC processors. Ralink’s RT3050 and RT3052 and Realtek’s RTL8196C chipsets are widely adopted in low-end and midrange products. The BCM5356 and BCM4718 from Broadcom and AR9001 from Atheros are popular in upscale models.
- Memory: Low-end routers have 16MB RAM and 4MB flash, and midrange counterparts adopt 64MB RAM and 8MB flash memory. Advanced releases pack 128MB RAM and 16MB or even 128MB flash. Makers use RAM chips from EtronTech, ESMT, Zentel, Winbond and Hynix, and flash memory chips from MX, Eon, Winbond, KH or Spansion.
- Antenna: Basic units come with one 1T1R antenna. Upscale versions adopt a multi-antenna configuration supporting 2T2R or 3T3R. Most models use fixed antennas, although detachable options are available. The average gain is 2, 3 or 5dBi.
