Summary

Customer Confidential 23 © Nokia Siemens Networks

Flexi EDGE BTS, Tata Taufik, 17 April 2008

Flexi BTS A BTS built with modules Cabinets are not needed with a module-based BTS

• Modules are in weather-proof casings with front and back covers (IP55) • Casings allow removal of the modules from the stack • Temperature range: -35°C …+50°C; temporarily +55 °C Modules can be installed in cabinets

Standard module (3HU)

133 mm

422* 560 mm 447 mm

• Casings are not used in cabinet installations Modules are small and light-weight

• One person can transport and install BTS without using lifting equipment

Weight approx 15-25 kg * 422 mm depth for cabinet-installed modules

HU = 44.4 mm
