Coverage of my home is...
About 100dB* less (On Sprint) than my -100dBmV** (Verizon) already being received by my house already.
I've got to get an antenna vs Holding my laptop above my head while typing in a CLI window to get anything done.
So, I get a Verizon PC-Card a Sierra Wireless Air Card 595. $30 for a Window Mount mobile style Antenna.... and ~ $85 for a mast mount 3ft tall Omni Directional. Plus another $10 for a total of 30ft cable for perma mounting in the house.
And the Data plan isn't to bad, $65/month for upto 3.1Mbit/sec download ~1.1Mbit/sec upload.
Personally if it gets 700K/200K is all I need for mobile usage.
* dB a a funky measurement thinger.
- +3.03dB == doubling in signal (energy)
- -3.03dB == halving in signal (energy)
- +10dB == 10 times increase in signal (energy)
- -10dB == 10 times reduction (or 1/10th) the signal (energy)
- +100dB == 10,000,000,000 times increase in signal (energy)
- -100dB == 10,000,000,000 times reduction of signal (energy)
** Yes this is a serious exaggeration, along with *. I am actually on the fringe for the three cell towers around my home. So... we are talking much better signal levels than stated, but it sure feels like the levels I stated.
