Wireless Router Edimax 3G-6218n Wi-Fi 4 Fast Ethernet White

The Edimax 3G-6218n is a compact portable wireless router with a built-in rechargeable Li-ion battery that enables mobile internet sharing without a power outlet. It supports USB 3G/3.5G modem cards as well as wired cable/xDSL modems via its Ethernet port and can automatically switch between connections. Compliant with IEEE 802.11b/g/n (Wi‑Fi 4), it delivers wireless data rates up to 150 Mbps and offers extended coverage compared with standard 802.11g/b routers.

Advantages

Smallest-in-class portability combined with an internal Li-ion battery provides up to approximately 4 hours of wireless connectivity for multiple users. Flexible dual-source Internet support lets you share a USB 3G/3.5G modem or a wired cable/xDSL connection, with automatic failover between interfaces. Broad device compatibility includes many smartphones for tethering, and the router implements green Ethernet technology to reduce power consumption by adapting output to link activity and cable length. Security and basic routing features (such as NAT and common wireless encryption standards) are supported for home and small-office use.

Suitable for

• Mobile internet sharing outdoors, during travel, or at temporary locations
• Small home or office setups requiring a compact backup internet source
• Users who need to share a 3G/3.5G USB modem or smartphone tethering
