Qiam, "قيام يک", means insurrection, or uprising. It is liquid fueled and is operated from a mobile transporter. The Qiam, is unique in that it doesn't correspond to any non-Iranian design, similar to the Iranian solid-fueled Sejil which has a range of about 2-2,500km. It is also similar to the Sejil in that very little information has been released about it. The lack of any major external differences (what i mean by this is that it largely fills the role of other missiles like the Shahab 2, there isn't as with the Sejil a major difference in roles and construction) indicates that there are major internal differences (as there were with the Sejil). It is visibly smaller than the Iranian liquid-fueled Shahab-3 which means it cannot use the same engine simply because of size issues and therefore must have a new one. I am actually a little disappointed its not a solid-fuel ballistic missile since they are technologically superior in terms of performance, range, and faster to deploy. Moreover, Iran has showed prowess in the past with solid-fueled systems. My own guess for the range of this system is below 2,000km (from 500km to 1,000km). What stands out is the lack of controlling fins, which attests to Iran's statement that the new system has maneuverability which is different from older ones.
Iranian television has stated that Iranian commanders have put forward that the new system is faster than the Shahab-3 --which is again liquid-fueled and I'm guessing of the same range, hence this could be a replacement for the older Shahab 2-- and has a new guidance package, which sets it apart from Iran's older systems. Reports also stated that the new missile requires even lesser time to prepare than the Shahab series. The media also stated that it can perform prior-calculated evasive maneuvers to avoid defense systems-- that it could deviate from it's path but remain on course to it's stated destination. From what other statements that were made, I gather it has a guidance system similar to that of the Iskander missile whose guidance system is it's best asset. Belarus and Russia continue to operate it. It could be said that Iran received key components of and so forth. These are my own guesses alone though.
Furthermore, My own opinion, which is probably wrong, is also that the Qiam was a test bed for the military and the Iranian space program simultaneously in that they have tested perhaps a new kind of liquid-fueled motor and/or a new fuel mixture for future SLVs and/or a new type of guidance system.
Iran also released a video about showing the kinetic impact from it. This is a first as much information can be deduced from it.
