ConsiderationsNEWLINKCabling SystemsWireless vs. Wired• WLAN technology is a tool design to coexist with LAN structured cablingsystems• The main WLAN advantage is : MOBILITY• In most cases, costing per unit, (Mega-bit / US$) wired points are more costeffective.This relationship is changing with time• Several special conditions give handicap for Wireless links• NEWLINK Super G Technology rises WLAN capacity in the Point to Pointschemes up to 108 Mb/s, equivaent to 75% of effective rate for full-duplex FastEthernet 100 Base-TX• Security levels on WLAN systems have been improved, always remain morevulnerable than wiredUSE WLAN EQUIPMENT WHEN IT BECOMES ASOLUTION, NOT A PROBLEM !

WLAN InstallationNEWLINKCabling SystemsStep by Step1. Check for Capacity Demand2. Define over a map the physical locations for each AP3. Make a Field Test to get real information. Benchmark.4. Adjust AP locations as needed. Use special antennas to getmore signal strength and coverage.5. Register and plot results and conclusions for future use6. Define a Security Plan and USE IT.

WLAN InstallationNEWLINKCabling SystemsTechnical Isues1. Access Point devices and Antennas are placed over a Field Test basis.2. RF signals are affected in several ways by walls, furniture and somedecoration finishes. Thick materials and metals act as barriers.3. For better reception think that RF signals travels in a line patternfromtheAP tothemobileuserandavoidbrickwallsin suchpath.4. Fire retardant doors and materials are excellent, to content fire andRF signals also.5. Keep the APs in a safe place, far away from other RF sources asmicrowaves, radio equipment, amplifiers.

WLAN InstallationNEWLINKCabling SystemsTechnical Isues6. Outdoor antennas increases RF Signal RECEPTION mainly.7. To connect external antennas use special Low-Loss Cables.8. Keep the AP as near as possible to the antenna.9. If you loss more signal strength in the cable that you gain with theantenna. Double check your locations.10. Use exterior antennas every time you want to keep a safe placementfor the AP but signl is not strong enough. ie. TelecommunicationsRoom, closed cabinet, etc.11. Use omni-directional antennas when you want to attend several usersfrom one AP.12. Use directional narrow antennas when you need long Point to PointLinks. i.e. Inter-building.

WLAN InstallationNEWLINKCabling SystemsTechnical Isues12. Consider power supplies and network cablingup to the planned AP location.13. Begin your setup changing small parametersat a time. Once the transmission is properlyadjusted, implement security and otherfunctions.14. Test the wireless links at short distances andthen go slowly far away the AP registering thedifferent values for signal strenght andeffective throughput. Use a laptop or palm.Plot them in a map.15. Change the placement for APs and Test againto double check.
