US Frequency Bands BandFrequency range UHF ISM MHz S-Band 2-4 GHz S-Band ISM GHz (The higher than cell phones - frequency allows the signal to carry more data.). C-Band 4-8 GHz C-Band satellite downlink GHz C-Band Radar (weather) GHz C-Band ISM GHz C-Band satellite uplink GHz X-Band8-12 GHz X-Band Radar (police/weather) GHz

What do the waves look like? Wave Video

Wireless Local Area Network (WLAN) Connecting two or more systems using wireless Standards WiFi uses radio waves Wireless cards are cheap Irda (direct line of sight – not as many security problems) 150 Feet

Access Point/Hot Spots An AP (access point also known as a AP) is the wireless server that connects clients to the internal network. AP’s typically act as a bridge for the clients. Wifi Wififreespot.com wi-fiplanet.com Boing.com Gogoair.com

Antennas Antennas come in all shapes and styles: – Omni-directional: Vertical Whip Ceiling mount – Directional: Yagi (“Pringles can”) Wall mounted panel Parabolic dish

HotSpots – Are they Safe?

Piggybacking on someone’s else Wireless Internet Google the name: David M. Kauchak

Bluetooth

proprietary open wireless technology standard for exchanging data over short distances (using short- wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices. WiFi – replaces cables for your network vs. Bluetooth – replaces cables for your devices 300 Feet

Bluetooth

Bluetooth Attacks Bluejacking -sends a message to a phone that you don’t know. Usually harmless. Bluesnarking – is unauthorized access of information & often times retrieves information. Blue bugging – similar to bluesnarking but leaves a backdoor and then the “hacker” can come and use the phone. Page

How to Secure Your Bluetooth Always Turn off your Bluetooth. Make Your Phone Visibility to Hidden. Set up a code when pairing devices Set your “Auto Connection without Confirmation” to No in all paired Devices.
