Optimizer Rooftop:<br />
Cleverly compact—<br />
powerful performance<br />
Striking the optimal balance between aesthetics, RF performance and<br />
capex/opex, RFS’s new Optimizer Rooftop is set to transform urban<br />
rooftops the world-over.<br />
The new Optimizer Rooftop is a unique all-in-one<br />
solution comprising base, mast, tri-sector<br />
antenna cluster and RF cabling. It strikes at<br />
the heart of the modern network manager’s<br />
most vexing problem—the visual impact<br />
requirements that often prove to be the<br />
‘Achilles’ heel’ of urban site acquisition and<br />
site renewal negotiations. Available now in<br />
selected regional markets, the Optimizer<br />
The Optimizer Rooftop has been developed with<br />
the site crew in mind, permitting easy assembly<br />
with simple tools and a two-person crew.<br />
(155 miles per hour) and mast deflection of less<br />
than one-degree at 160 kilometers per hour<br />
(100 miles per hour).<br />
Total lifecycle cost reduction<br />
The Optimizer Rooftop reduces the total<br />
lifecycle cost of the rooftop base station, by<br />
providing premium value to all stakeholders. At<br />
the site-acquisition stage, its slim lines and<br />
reduced visual and architectural impact ensure<br />
that costly new site rejections and existing lease<br />
cancellations are avoided.<br />
During site-installation, the Optimizer Rooftop<br />
dramatically cuts labor and equipment<br />
costs. As the entire assembly breaks down<br />
into conveniently light and maneuverable<br />
components, the entire Optimizer Rooftop can<br />
be transported with a small team—from<br />
street-level to rooftop—using conventional<br />
building access (stairways or elevator). No crane<br />

• Side-by-side (a paired combination of<br />
1800 MHz and 2200 MHz) in 1.3 and<br />
1.8 meter lengths (4.25 and 6 ft)<br />
• Triple-band (900/1800/2200 MHz) in<br />
2 and 2.6 meter lengths (6.5 and 8.5 ft)<br />
• Dual-band (in paired combinations of<br />
900 MHz + 1800 MHz and 900 MHz +<br />
2200 MHz) in 1.3 and 2 meter lengths<br />
(4.25 and 6.5 ft)<br />
