Smart, Inexpensive Detection & Analysis
1. Sensing Wireless Connections
Roadrunner RF detects Bluetooth™ and 802.11 wireless Local Area Network (Wi-Fi) connections on-the-fly at intersections. These signals are found on Apple iPhones (4, 4S, 5, 5S, 5C, iPad (2, 3, 4, Air, Mini, Retina), all Android-equipped phones (Acer, Asus, HTC, HuaWei, LG, Kyocera, Motorola, Samsung, Sony and ZTE). Carriers for the phones include AT&T, Springt, T-Mobile, U.S. Cellular, Verizon wireless, and Virgin Mobile. In addition, wireless navagation systems, such as TomTom, nuvi, Magellan, and other in-car systems use wireless connectivity.

The 802.11a, 802.11b, and 802.11g components are based on a fork of work released in April 2007 by a team at the Darmstadt University of Technology in Germany, which in turn was based on a paper published in 2001 on the RC4 cipher by Scott Fluhrer, Itsik Mantin, Adi Shamir. Sampling time can be varied, as can the channels.
3. Data Analysis
Roadrunner currently uses a MySQL implementation and a PostgreSQL version. Our objective is to be the most cost effective RF traffic analysis tool on the market, so we have chosen open source products.
PostgreSQL (pronounced Post-gress-cue-ell) bills itself as the world’s most advanced open source database. Some of its fans say it is as good as Oracle, but without the baggage of high cost and snooty customer service. It has a long history, having been developed originally in 1985 at the University of California, Berkeley, as a descendant of the Ingres database.
PostgreSQL is a 100% community-driven open source project, maintained by a worldwide community of more than a thousand contributors. It provides a single completely functional version, rather than the multiple different community, commercial, and enterprise versions that MySQL offers. Its license is a liberal BSD/MIT-type, which allows organizations to use, copy, modify, and redistribute code with only a copyright notice required.
Reliablity is PostgreSQL’s top priority. It is known for being rock-solid and well-engineered, capable of supporting high-transaction, mission-critical applications. Documentation is first-rate, with comprehensive manuals available for free online, along with archives of manuals for older releases. Community support is excellent, and commercial support is available from independent vendors.
MySQL is relatively new, first appearing in 1994. It calls itself the world’s most popular open source database. MySQL is the M in LAMP, the software bundle frequently used for web development that also includes Linux, Apache, and Perl/PHP/Python. Most applications built on a LAMP stack incorporate MySQL, including such well-known applications as WordPress, Drupal, Zend, and phpBB.
Initially MySQL was designed to be a fast web server back end, using a fast indexed sequential access method (ISAM), with no ACID support. Since those lean, speedy early days MySQL has added support for a number of additional storage engines, and ACID compliance is now available via the InnoDB engine. MySQL also supports other storage engines, providing capabilities such as temporary tables using the MEMORY storage engine, an example for developers with the EXAMPLE storage engine, fast read-mostly databases using the MyISAM engine, plus several other core storage engines and a number of third-party engines.
