Rohm, a Japanese semiconductor company, has created a silicon chip and antenna that’s currently capable of transmitting 1.5Gbps, with the potential to scale up to 30Gbps in the future. By comparison, the fastest 802.11 (WiFi) transmission speeds max out at around 150Mbps, and the incoming WiGig standard peaks at 7Gbps.

Whenever I talk or write about my own security setup, the one thing that surprises people — and attracts the most criticism — is the fact that I run an open wireless network at home. There’s no password. There’s no encryption. Anyone with wireless capability who can see my network can use it to access the internet.
OpenWrt is described as a Linux distribution for embedded devices.
Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developer, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Tomato USB is an alternative Linux-based firmware for powering Broadcom-based ethernet routers. It is a modification of the famous Tomato firmware, with additional built-in support for USB port, wireless-N mode support, support for several newer router models, and various enhancements.
Note: If printed at the download size you will see about 9 dBi of gain. If you double the size of the image before you print it you will see about 12 dBi of gain. If you place two reflectors on an AP with two antennas you will see an additional increase in performance.
For this project you are going to need scissors, a utility knife, some adhesive putty and an empty beer can. More than one empty beer can is acceptable but don’t kid yourself, the router only needs the one.
