Wireless vs. Wired

• WLAN technology is a tool design to coexist with LAN structured cabling systems

• The main WLAN advantage is : MOBILITY

• In most cases, costing per unit, (Mega-bit / US$) wired points are more cost-effective. 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 Point schemes up to 108 Mb/s, equivaent to 75% of effective rate for full-duplex Fast Ethernet 100 Base-TX

• Security levels on WLAN systems have been improved, always remain more vulnerable than wired

Considerations

USE WLAN EQUIPMENT WHEN IT BECOMES A SOLUTION, NOT A PROBLEM !

Cabling Systems

NEWLINK

Step by Step

1. Check for Capacity Demand

2. Define over a map the physical locations for each AP

3. Make a Field Test to get real information. Benchmark.

4. Adjust AP locations as needed. Use special antennas to get more signal strength and coverage.

5. Register and plot results and conclusions for future use

6. Define a Security Plan and USE IT.

WLAN Installation

Technical Isues

WLAN Installation

1. Access Point devices and Antennas are placed over a Field Test basis.

2. RF signals are affected in several ways by walls, furniture and some decoration finishes. Thick materials and metals act as barriers.

3. For better reception think that RF signals travels in a line pattern from the AP to the mobile user and avoid brick walls in such path.

4. Fire retardant doors and materials are excellent, to content fire and RF signals also.

5. Keep the APs in a safe place, far away from other RF sources as microwaves, radio equipment, amplifiers.

NEWLINK

6. 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 the antenna. Double check your locations.

10.Use exterior antennas every time you want to keep a safe placement for the AP but signl is not strong enough. ie. Telecommunications Room, closed cabinet, etc.

11.Use omni-directional antennas when you want to attend several users from one AP.

12. Use directional narrow antennas when you need long Point to Point Links. i.e. Inter-building.

12. Consider power supplies and network cabling up to the planned AP location.

13. Begin your setup changing small parameters at a time. Once the transmission is properly adjusted, implement security and other functions.

14. Test the wireless links at short distances and then go slowly far away the AP registering the different values for signal strenght and effective throughput. Use a laptop or palm. Plot them in a map.

15. Change the placement for APs and Test again to double check.
