Application and Advantage :

HUAWEI HG8245A WIFI GPON ONU with 4 FE + 2 POTS ports , is a high-end home gateway in Huawei FTTH solution.

By using the EPON technology, ultra-broadband access is provided for home and SOHO users.

The HG8245 provides two POTS ports, four FE ports and one WiFi antenna.

The HG8245 A features high-performance forwarding capabilities to ensure excellent experience with VoIP, Internet and HD video services.

Features:

  • Port: 2POTS+4GE+1USB+WiFi.
  • Plug-and-play (PnP): Internet, IPTV and VoIP services can be deployed by one click on the NMS and on-site configuration is not required.
  • Remote diagnosis: Remote fault locating is implemented by the loop-line test of POTS ports, call emulation and PPPoE dialup emulation initiated by the NMS.
  • High speed forwarding: GE line rate forwarding in the bridge scenario and 900 Mbit/s forwarding in the NAT scenario.
  • Green energy-saving: 25% power consumption is saved with highly integrated system on chipset (SOC) solution, in which, a single chip integrates with PON, voice, gateway and LSW modules.

Wireless Router

From Wikipedia, the free encyclopedia

A wireless router is a device that performs the functions of a router and also includes the functions of a wireless access point. It is used to provide access to the Internet or a private computer network . It can function in a wired LAN (local area network), in a wireless-only LAN (WLAN), or in a mixed wired/wireless network, depending on the manufacturer and model.

Features


Most current wireless routers have the following characteristics:

  • One or multiple NICs supporting Fast Ethernet or Gigabit Ethernet integrated into the main SoC
  • One or multiple WNICs supporting a part of the IEEE 802.11-standard family also integrated into the main SoC or as separate chips on the printed circuit board. It also can be a distinct card connected over a MiniPCI or MiniPCIe interface.
    • So far the PHY-Chips for the WNICs are generally distinct chips on the PCB.  Dependent on the mode the WNIC supports, i.e. 1T1R, 2T2R or 3T3R, one WNIC have up to 3 PHY-Chips connected to it. Each PHY-Chip is connected to a Hirose U.FL-connector on the PCB. A so-called pigtail cable connects the Hirose U.FL either to a RF connector, in which case the antenna can be changed or directly to the antenna, in which case it is integrated into the casing. Common are single-band (i.e. only for 2.4 GHz or only for 5 GHz) and dual-band (i.e. for 2.4 and 5 GHz) antennas.
  • Often an Ethernet switch supporting Gigabit Ethernet or Fast Ethernet, with support for IEEE 802.1Q, integrated into the main SoC (MediaTek SoCs) or as separate Chip on the PCB.
  • Some wireless routers come with either xDSL modem, DOCSIS modem, LTE modem, or fiber optic modem integrated.
  • IEEE 802.11n compliant or ready.
  • Some dual-band wireless routers operate the 2.4 GHz and 5 GHz bands simultaneously.
  • Some high end dual-band wireless routers have data transfer rates of at most 300 Mbit/s (For 2.4 GHz band) and 450 Mbit/s (For 5 GHz band).
  • The Wi-Fi clone button simplifies Wi-Fi configuration and builds a seamless unified home network, enabling Super Range Extension, which means it can automatically copy the SSID and Password of your router.
  • Some wireless routers have one or two USB ports. For wireless routers having one
  • USB port, it is designated for either printer or desktop/mobile external hard disk drive. For wireless routers having two USB ports, one is designated for the printer and the other one is designated for either desktop or mobile external hard disk drive.
  • Some wireless routers have a USB port specifically designed for connecting mobile broadband modem, aside from connecting the wireless router to an Ethernet with xDSL or cable modem. So, can be inserted a mobile broadband USB adapter into the router to share the mobile broadband Internet connection through the wireless network.

Operating System


The most common operating system on such embedded devices is Linux. More seldomly, VxWorks is being used. The devices are configured over a web user interface served by a light web server software running on the device.

It is possible for a computer running a desktop operating system such as Windows to, with appropriate software, act as a wireless router. This is commonly referred to as a SoftAP, or “Software Access Point” (aka “virtual router”).

Open Source Firmware

In 2003, Linksys was forced to open-source the firmware of its WRT54G router series (the best-selling routers of all time) after people on the Linux Kernel Mailing List discovered that it used GPL Linux code. In 2008, Cisco was sued in Free Software Foundation, Inc. v. Cisco Systems, Inc due to similar issues with Linksys routers.

Since then, various open-source projects have built on this foundation, including OpenWrt, DD-WRT, and Tomato.

In 2016, various manufacturers changed their firmware to block custom installations after an FCC ruling. However, some companies plan to continue to officially support open-source firmware, including Linksys and Asus.
