D-Link DWR-730 - Mobile hotspot - 3G - 21.6 Mbps - 802.11n

The Portable HSPA+ 21 Mbps Router (DWR-730) allows you to connect your notebook, tablet and smartphone to the Internet from anywhere there is a 3G connection and share this connection with other users wirelessly. This router is ideal for people that need a portable solution, for example remote workers or people that are moving house and need a temporary Internet connection.
You can use this router to share your 3G connection wirelessly. The router will use an available 3G connection to provide a fast and secure Wireless N 150 network for several users at the same time.
The device is small enough to fit in your pocket: the rechargeable Li-ion battery means that you can take it with you anywhere and surf the Internet, and if you need to recharge it, you can do it easily with any USB wall or car charger.
The DWR-730 supports the latest High Speed Packet Access Plus (HSPA+) technology, which offers data rates of up to 21.6 Mbps (5.76 Mbps upload) and helps to reduce latency. This router is also backwards compatible with mobile networks implementing HSUPA and HSPDA technologies.
It may be small but it can keep your wireless connection as secure as if you were connected through your home network. Its built-in firewall prevents potential attacks and hacking attempts from the Internet, and with WPA2 encryption, you can be sure that you are sharing your 3G connection only with the users you want to.
