CTS 091 – New York City – A Connected City - Clear To Send: Wireless Network Engineering
Summary: New York City flipped the switch and enabled Wi-Fi and cellular network in all underground subway stations. Jeremy Ward, of Transit Wireless, joins us to talk about this large scale project and what it took to do it.<br> This episode is sponsored by Metageek<br> <a href="http://metageek.com" target="_blank" rel="noopener"></a><br> New York City – A Connected City<br> <br> Jeremy Ward of Transit Wireless joins us on the show to talk about getting the underground subway stations connected with Wi-Fi and cellular connectivity. The project includes 120 miles of fiber optic cabling, 4,000 cellular antennas, and 5,000 Wi-Fi access points. The network supports the users who use mass transportation every day, public safety, transit communications, and over 3,000 Help Point kiosks for riders.<br> Jeremy discusses the challenges that came up with deploying a solution like this in an underground subway station. Many challenges to Wi-Fi make planning very important. There are issues from the environment, including:<br> <br> * Noise<br> * Dirt<br> * Heat<br> * Cold weather<br> * Brake dust from the trains<br> * Pressure washers<br> * Vandalism<br> * and RF<br> <br> It’s very possible to get RF reflected from moving trains!<br> Placement can be tough to tackle underground. One of the important things to consider is vandalism. Jeremy’s team has tested different enclosures by taking a baseball bat to them!<br> Other topics discussed on this episode:<br> <br> * Design requirements<br> * User traffic<br> * Hardware considerations<br> * Extreme Networks<br> * Motorola<br> * Wireless LAN Controllers<br> * Security<br> * Analytics<br> <br> New York City Subway Wi-Fi Stats<br> <br> Links & Resources<br> <br> * <a href="https://twitter.com/Realjeremyward" target="_blank" rel="nofollow noopener">@realjeremyward</a><br> * <a href="https://transitwireless.com/" target="_blank" rel="nofollow noopener">Transit Wireless</a><br> <br>
