If you wanted a highly portable, super-small wireless router that is very flexible in how it connects you to the internet and how it can be powered, then check out the RB-1132 N+ Mini Broadband Router from Sapido. For Internet access, the router has a WAN Ethernet port and a USB 2.0 port. With the WAN Ethernet port, you can establish a wired connection to a cable modem, ADSL modem, or, as commonly found in hotels and offices, a LAN network jack. With the USB 2.0 port, you can connect to your WiMax modem*, your 3G or 4G USB broadband modem, or, with the correct adapter cable, your Smartphone. In addition, the router can also spread a wireless signal when wirelessly connected to WiFi modems or other wireless routers. Since this router is designed to 802.11n wireless specifications, you can connect a vast array of wireless-N devices at a data transfer rate of up to 300 Mbps. It can also connect to wireless devices that are only compatible with 802.11b or 802.11g standards. Plus, with one built-in 10/100 Mbps Ethernet LAN port, you can also establish a separate wired connection to your computer.
Because the router is designed to be extremely portable, it can be powered in a few different ways. It can directly plug in to an AC power outlet or it can be DC-powered by a laptop, USB car charger, or USB battery. You'll need a Y type USB cable to connect to a laptop. Also, the router is built to 802.3az Ethernet standards and features a built-in Green AP technology. With these, the router can moderate its power consumption as it needs, which ends up wasting less energy. For security, you can either utilize the one-touch WPS encryption button or you can use the more advanced security options. This router is compatible with your Windows, Mac, or Linux computer.
