TELAR vehicle can also be used independently, but then its ability to identify a goal is reduced and the risk to fire against a wrong target will rise, says Pulkki.
"TELAR's radar can only tell that there is a plane flying in there. Subsequently, the missile can be locked on to it, and fired", tells Pulkki.
"If TELAR is used by one person or otherwise ill-trained team without the support of separate surveillance radar vehicle and command link, it is very possible that the target's quality and altitude are not exactly clear." "

Pulkki is a some kind of weapon system specialist, I'm not sure if he has worked with Buk-systems of Finnish Army. If TELAR's altitude reading for MH17 was inaccurate, operator might have thought it was a military plane in no-fly zone . Reportedly MH17 was flying 1 000 feet above restricted zone, at 33 000 feet.
Exactly, this is my understanding as well. Rebels had the racket launcher unit (despite their denials now). This is documented by pictures, videos and them themself bragging about it on social media. They did not have the other pieces of the system, so they had no idea what they were shooting at. I guess Russians didn't think it through before giving them the SAMs. This is why they are removing the equipment form rebel territory now to hide the evidence.

From 35000 to 33000 feet. Not significant IMHO. The airspace was closed below 32000 but Buk SAMs had capacity in the 70000-80000 range.
