6. Updated: April 21, 2010 You Heard about me Tell me what you wish to learn 1.Personal or Serious Business Interest? 2.How many of you use a)Dialup? b)DSL? c)Cable? d)Satellite? e)T1? f)Other? 3.How many different Internet Access methods are available at your location?

7. Updated: April 21, 2010 Some Internet Access Options 1.Dialup 2.DSL – ADSL, IDSL, SDSL 3.Cable – very variable as a function of neighbours usage 4.FiOS – What other service is this most like? 5.Satellite 6.Fixed Wireless – 3G, 4G 7.Fixed Wireless – Microwave 8.T1 9.Fast Ethernet – Pure, EoC, EoDS1, EoDS3 10.DS3 11.OC3 - OCx 12.GigE

8. Updated: April 21, 2010 Internet Access Options 1.Typically, several carriers offer DSL to each eligible location 2.Cable – probably only one provider in area 3.Satellite – couple providers 4.3G Fixed Wireless – several providers 5.4G Fixed Wireless – limited, growing availability 6.Microwave Fixed Wireless – may or may not be available from one or more providers 7.T1 – always available usually from wide choice of providers 8.Fast Ethernet – may or may not be available from one or more providers 9.DS3 – always available but may require buildout 10.OC3 - OCx – more likely to require buildout 11.GigE – more likely to require buildout

9. Updated: April 21, 2010 Internet Access Availability 1.DSL – Dependent on distance from CO (Telephone Company Central Office), on quality of wiring, and on facilities at CO 2.Easy to understand cable service is not available if cable is not run to your building likewise for FiOS 3.3G Fixed Wireless – most areas of USA are covered by at least one carrier 4.4G Fixed Wireless – very limited areas have availability today but areas growing rapidly 5.Microwave Fixed Wireless – depends on your being in line of sight of a fixed wireless antenna 6.T1, DS3, OCx – always available usually from wide choice of providers; pricing depends on which CO you are connected to and sometimes on distance from the CO 7.Fast Ethernet – depends on whether building is lit or for EoC, EoDS1 and EoDS3 whether facilities are in place at CO and distance from CO 8.GigE – depends on whether building is lit

10. Updated: April 21, 2010 Bandwidth (i.e. speed) Is it the most important characteristic? Will a. or b. in the comparisons below provide better service? a.6 Mbps x 2 Mbps cable connection b.3 Mbps x 768 Kbps DSL connection a.3 Mbps x 768 Kbps DSL connection b.1.5 Mbps x 1.5 Mbps DSL connection a.3 Mbps x 768 Kbps DSL connection b.1.5 Mbps x 1.5 Mbps T1 connection

11. Updated: April 21, 2010 Reliability SLA (Service Level Agreement) Up Time MTTR (Mean Time To Repair) Bottom Line – If a business is critically dependent on the connection, its often a no brainer to pay the additional amount required for T1, DS3, or Ethernet type services

12. Updated: April 21, 2010 Bandwidth Consistency Typically cable has the worse bandwidth consistency DSL, 3G Fixed Wireless and FiOS are next – the saving factor with FiOS is that the bandwidth is so much greater than needed that after a huge decrease in bandwidth, there may still be enough left Microwave Fixed Wireless is between 3G Fixed Wireless and T1 – often comparable to T1 bandwidth consistency T1, DS3, OCx and Ethernet have the best

13. Updated: April 21, 2010 Latency, Packet Loss and Jitter Do you care? Yes, if you are transmitting audio (e.g. VoIP) or video, or playing on-line games For Email and batch file transfer, these dont matter SLAs for T1, DS3, OCx and Ethernet services usually provide pretty good latency, packet loss and jitter guarantees
