When available highbrow 802.11ac Wi-Fi products, after the terminal device (wireless network card, mobile phone, tablet) is gradually introduced into the application, have become increasingly popular phenomenon. Taiwan agent Netis EF2780 recently launched, buttressed 2T2R dual and GbE network synchronization specifications, $2,000 price.
Netis the Netcom brand Taiwanese consumers may be somewhat unfamiliar, this is 2012, when the introduction of Taiwan agent, the main push is more affordable and economical network products. The evaluation of the Netis WF2780, just launched on the medal of $2,000 price band for its 802.11ac specifications and GbE wired internet, in the market is really quite affordable choice.
Netis WF2780 Specifications:
- Fi SoC: Realtek RTL8197DN
- Switching chip: Realtek RTL8367RB
- Wi-Fi chip: Realtek RTL8192ER (802.11 b / g / n), RTL8812AR (802.11 a / n / ac)
- Antenna: 4.96dBi, 5.42Bbi (2.4GHz), 5.02dBi, 5.43dBi (5GHz), fixed
- Cable Internet: 10/100 / 1000Mbps
- Wi-Fi: 802.11 a / b / g / n / ac, 2T2R
- Port: RJ45 x 5
- Memory: 64MB DDR2
- Dimensions: 325 x 257 x 72 (mm)
The main core of the use of Realtek RTL8197DN, containing a Lexra RLX5281 RISC processor, the clock can be set to 500MHz ~ 660MHz range (exact time unknown pulse). Connecting peripheral part is there are two PCIe lanes, two-port USB 2.0 ( Netis WF2780 is not used), and 5-port 100Mbps network physical layer, in addition to a group GMII / RGMII / MII interface.
Netis WF2780 is to give up the built-in network physical layer, instead use an external RGMII RTL8367RB exchange wafers, the product has a wired network GbE level. Memory part can support SD / DDR / DDR2, a built-in 64MB DDR2 memory.
Wi-Fi is referred RTL8192ER and RTL8812AR responsible, both are using the PCIe link and RTL8197DN former is responsible for the 2.4GHz 802.11 b / g / n, which is responsible for the 5GHz 802.11 a / n / ac, are all terms of the number of antenna transceiver 2T2R.
