| LTO |
Long Term Orbits. Broadcom's patented technology brings GPS assistance data to mobile device users who do not have the benefit of Assisted-GPS (AGPS) infrastructure in their wireless networks. GPS-enabled mobile devices equipped with LTO deliver AGPS-enhanced performance without sacrificing the reedom of autonomous operation. |
