- 8. www.glcnetworks.com Wired communication ● Using physical media to connect tx and rx ○ Metal: copper ○ Glass: fiber optic ● Generally requires 2 cables: ○ One for TX ○ One for RX ● Data must travel inside the medium ● Not flexible. Cannot move devices easily or far ● Faster data rate ● Very stable connection (low error rate) 8 Image: http://www.leviton.com/
- 9. www.glcnetworks.com What is wireless communication? ● Communication without physical connection between TX and RX -> no wire ● Make user more flexible and portable ● Easy to deploy ● Data travel through freespace ● Need to have common standard ● Need to understand how wireless works ● Slower datarate ● 9 Pic: http://synfrait.com
- 10. www.glcnetworks.com Simplex vs duplex communication ● Simplex: one way communication ○ Broadcast: TV, radio ○ streaming ● Duplex: two way communication. TX and RX exchanging data ○ Full-duplex: tx and rx exchanging data in the same time Ex. telephone, switched network ○ Half-duplex: tx and rx takes turn when exchanging data Ex. handy talky, wifi, hub-network 10
- 11. www.glcnetworks.com What is wave? ● Wave: a vibration that travels through a medium from one location to another location ● Wave properties: frequency (Hz), lamda (m), period (sec) ● Amplitude determine how loud the signal is ● The wave we use for communication: electromagnetic wave ● Electromagnetic wave is generated by oscillation of electricity and magnetism ● 11
- 12. www.glcnetworks.com Channel, width, signal strength, coverage ● We use different frequency (channel) to distinguish communication ● TX and RX must use same frequency for communication ● Some communication requires wider frequency to be used -> this is known as channel-width or bandwidth ● Protocol will specify frequency, Channel-width to be used in communication. E.g. 802.11 protocol uses 20MHz width ● Higher amplitude -> Stronger signal -> can travel far -> cover more area 12
- 13. www.glcnetworks.com Interference ● Interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude ● Can be constructive or destructive -> destroy signal ● Happens when 2 sources using same/near frequency ● Tips: use non-overlapping signal. E.g. channel 1,6,11 13 Constructive destructive
- 15. www.glcnetworks.com What is Ubiquiti ● A network devices manufacturer, Based in USA ● Product group: ○ Airmax: for wireless backbone ○ Unifi: for enterprise solution: wireless, cctv, iphone ○ EdgeMAX: for wired communication ○ AirFiber: for high capacity backhaul ○ solarMAX: solar panel 15
