Hi, first my system: \r\n\r\nXPS 15 (L502x), core i7 2630qm, 4GB ddr3, gt 540m 2GB, intel advanced 6230 wifi+bt. \r\n\r\nI'm from Colombia, my network operator here is "movistar" who have 3.5g in the band of 850Mhz; actually im using an Huawei E226 USB modem to connect to internet. \r\n\r\nI'm a very mobile person and i don't want to use the USB modem, i was thinking in this minipci-e card: \r\n\r\nebay.com/itm/Unlocked-Sierra-MC8781-3G-WWAN-HSDPA-Medom-GPS-Free-Antenna-/300615833014?pt=LH_DefaultDomain_0&hash=item45fe1995b6#ht_1552wt_103\r\n\r\nOn the other hand i want some security: any kind of security is in my notebook, no user password, admin account, so that in case of robbery the thief not have to format it (the easy way). I want that every time when windows boot or start session the GPS send the location coordinates to my email. \r\n\r\nSO, i have a few questions in my mind without answer, i hope you can help me: \r\n\r\n1) Is that a good WWAN+GPS card? or can you recommend me a better one? \r\n2) is there a software that start with windows and run in the background or minimized that automatically send the actual coordinates to my email? \r\n3) can i use internet connection and the GPS at the same time without the aux antenna? \r\n4) which is the purpose of the aux antenna? \r\n\r\nThanks in advance!
