6.2.2.2. Antenna Specifications
For any other antenna applied, it must fulfill the requirements specified in the table below.
The optimum operating frequency depends on the application. A dual-band or quad-band antenna
should operate in these frequency bands and have the following characteristics:
Table 28. GL61x0 Antenna Specifications
0dBi in one direction at least
Tip: Both mechanical and electrical antenna adaptations are key issues in the design of a GSM terminal.
Sierra Wireless strongly recommends working with an antenna manufacturer to either develop an
antenna adapted to the application or to adapt an existing solution to the application.
