infrared and bluetooth
Today s wireless network environments are not limited only to 80211 wireless LAN equipment As a Network+ professional, you should be familiar with other popular wireless standards such as infrared and Bluetooth
infrared
Infrared wireless is the type of wireless communication that is used by VCR and TV remote controls, along with some computer peripherals Infrared is typically a line-of-sight technology, which means that the signal is lost if anything blocks the pathway between the two devices With infrared, the two devices will need to be within one meter of one another Infrared devices contain a transceiver that sends and receives light signals as on-off patterns to create the data that travels at transfer rates up to 4 Mbps Because line of sight is required, you may need to use a radio frequency solution such as Bluetooth if line of sight becomes an issue
bluetooth
Bluetooth is a radio frequency wireless technology that allows systems to connect to peripherals over a distance of up to 10 meters away Bluetooth is more flexible than infrared because it will automatically connect to other Bluetooth devices and does not depend on line of sight This is a popular technology used by handheld devices to connect to other networking components Bluetooth is less susceptible to interference because it uses spread-spectrum frequency hopping, which means that it can hop between any of 79 frequencies in the 24 GHz range Bluetooth hops between frequencies 1600 times per second and provides a transfer rate of up to 1 Mbps Bluetooth is a popular technology with handheld devices such as PDAs and cell phones Bluetooth is popular with these devices so that users can use their wireless headsets with their cell phones and talk hands free
Certification Summary
There are huge security risks with Bluetooth, as it is possible for a hacker to connect to your cell phone remotely via Bluetooth and steal data off your phone In order to secure your Bluetooth-enabled device, follow these best practices:
n Disable Bluetooth n Phone Visibility
If you are not using the Bluetooth feature on your phone, then disable Bluetooth through the phone s menu system If you are using Bluetooth, then set the phone s visibility setting to invisible so that hackers cannot pick up on your phone with a Bluetooth scanner Ensure you are using a Bluetooth phone that uses pair security, which allows people to connect to your phone only if they know the PIN code you have set on the phone
n Pair Security

In this chapter you have learned about wireless basics and the security issues surrounding wireless You have learned that wireless networks come in two forms, infrastructure mode or ad hoc mode Infrastructure mode uses a wireless access point, while ad hoc mode allows clients to connect to one another You have also learned about wireless standards such as 80211b, 80211g, and 80211n 80211b is an old wireless standard that runs at 11 Mbps, while 80211g runs at 54 Mbps and 80211n runs at over 300Mbps You have learned that there are many steps to securing a wireless network, such as limiting which systems can connect through MAC filtering, encrypting traffic with WEP or WPA, and making sure to change the SSID and disable SSID broadcasting You have learned that all these measures have been compromised by hackers, so if security is a concern you should look to using a VPN solution with your wireless network
