I have heard about the Applet mentioned by 'wire_twister'
Much less "Invasive Feeling" to your Crews, as would be the Tracking (GPS) Applet types, or those Applets which function similar to the older "Login/Logout Wands".
Did not know the Applet used the Devices' CPU RTC (Real-Time Clock) for accrued Time. That would be quite helpful for Workers crossing Time Zones, where the Cell Triangle will update the Time displayed on the Device per Time Zone; either gaining one hour moving Eastward, or losing one hour moving Westward.
Hey Jimmy (wire_twister);
when you are working in Fringe areas (areas with "less-than usable" Signal Strength) do you place your Device Off-Line (i.e.: "Airplane Mode"), so as to reduce Battery Drain from the Device constantly trying to connect to ("Ping") a usable Node?
Back in 2001/2002, I was traveling between Southern and Northern California frequently via Ca. 99 and/or I-5.
There used to be a Fringe Signal Area across the "Grapevine"; a +/- 70 Mile stretch of highway (I-5), running through the Southern end of the Sierra Nevada Mountain Range.
The Fringe area began apx. 15 Miles North of Santa Clarita, and ended somewhere close to the I-5 / Ca. 99 Interchange; covering close to 90 Miles.
Back then, we all used Motorola i1000 Devices, with iDEN Protocol.
If the Device was left On while traveling through the Fringe Area, the constant Pinging would drain the Battery drastically.
So it became SOP (Standard Operating Procedure) to connect our Devices to the Cigarette Lighter Travel Charger, after leaving the Shop in Santa Clarita.
There were several other Fringe Areas North of Delano, these only lasted a few Minutes while traveling at >75 MPH... (the highways of Central California are jokingly referred to as "California Autobahn 5 / 99").
BTW, prior to mid 2002, the Southern California based Nextel "Direct Connect" and "Group Connect" user range ended at the borderline of overlapping Cells, apx. 15 Miles North of Santa Clarita.
