Selecting an Installer

What CA contractors licenses do you have? C-10 License or C7 required, C7 preferred https://www2.cslb.ca.gov/OnlineServices/CheckLicense/LicenseRequest.asp https://www2.cslb.ca.gov/OnlineServices/CheckLicense/LicenseDetail.asp?LicNum=858920

Are you insured and bonded?How do you test the installed system?What test equipment do you use?Is there a manufacturer warranty with the

installation? How do you train your technicians?Who holds the manufacturer certificates?

Hub and SwitchesDevice General

CharacteristicsGeneral Use

Hub All ports share single signal

Home - Obsolete

Switch Each port has its own signaling

Home/small network

Layer 2 Switch Switch, Plus simple management tagging

Where you need network separation Vlans – I.E. Accounting, staff

Layer 3 Switch Layer 2 Switch, Plus Routing

Where you need communication between Vlans – IE VoIP, Security

SummaryCable matters

CAT6 vs. CAT5/5e 20% more expensive (Cable, Jacks, Patch Panels, Patch Cords) 1-10Gbps vs. 100Mbps-1Gbps 10 times faster Better signaling Reduced Equipment Fatigue/Failure Reduced Maintenance costs CAT5/5e May not be able to deploy network demanding

applications (VoIP, IP Security Cameras, etc..)

Engineered end to end solution (Good Quality vs. Low Quality Cable ) Equipment error / correction can range between 1/2% to 5%

Equipment Matters Select named brand manufacturers Non POE vs. POE switches vs. Power injectors Equipment speed and throughput should match cabling system

Select a cable installer that specializes in voice and data cabling

SummaryWireless 802.11 n vs. 802.11 g

3X the throughput Need to match computer network cards for best

performance

What’s the Cost of a poor network solution Lost Productivity Delayed Response Time Increased Maintenance Costs

Hardware fatigue / failure Down Time

Error in information transmission (especially with more demanding IP applications such as VoIP, video)

$$$$ - do the math, down time, delays, equipment failures
