Wireless

• Provide physical ports RJ-45
• Allow network connections to be used over radio signal (wirelessly) which extends the usage beyond the available jacks of the router

Speed and Range

• Each Wireless Node can have different range for wireless connection based on radio signal frequency and send certain amounts of data

Signal Standards

• IEEE 802.11
• Bandwidth can happen in different channels with 5Ghz and 2.4 Ghz
• 2.4Gh can have 14 channels
• 5 Ghz can have 8 channels

Inferred

• Half dupliex, can only listen or talk
• Fast, can move 4 Mbps

Bluetooth

• PAN (personal area network)
• Allow to connect various devices wirelessly to each other
• Power consumption can very based on tye type of device being used, or consuming

WAN

Troubleshooting

• Misconfigured Network Interface Card (NIC)
• Misconfigured Domain Name Server (DNS)
