- | On the N900 there are three ''Reverse Polarity'' [http://en.wikipedia.org/wiki/Hirose_U.FL Hirose U.FL] connectors. These RP Hirose U.FL connectors were noted as test connectors however with the right equipment attached these can be used to increase the range of the said chips that has such connectors attached, if not to increase range it can be used possibly in other ways | + | On the N900 there are three ''Reverse Polarity'' [http://en.wikipedia.org/wiki/Hirose_U.FL Hirose U.FL] connectors.

The three chips that have RP Hirose U.FL connectors attached are: GSM, GPS and Bluetooth/Wireless LAN. Note that the Bluetooth/Wireless LAN share the same Hirose U.FL connector. | The three chips that have RP Hirose U.FL connectors attached are: GSM, GPS and Bluetooth/Wireless LAN.
