High coverage of newly reframed LTE850 band

[ank707]

Hi Guys,

Recently U-850 refarming was made in our market and now we have a new 5MHz LTE 850 carrier. The new carrier has unusually high PRACH when compared to the same co-located carriers in the sector that have the same reference signal power. Ideally L700 with same RS power should have more coverage compared to L850 but here we see in general the coverage is 3-4 times even when compared to L700. Antenna height is same with same orientation as other carrier. L850 antenna is same as that of L700 so same gain as well. Height of the antennas are also same.All logical parameters of L700 and L850 is same.

Has anyone of you experienced similar issue or can share their experience with similar issue of a refarmed 5Mhz L850 carrier ?
