Model tunning and K factors
Dears,
We want to plan a city for UMTS 2100 and we do not have tunned model for this frequency but we have tuned model for 1800. Do you have any idea how to convert the 1800 Kfactors to use in UMTS 2100?
How about if we consider K1 3dB higher ?
how about if we consider 3db loss per all clutters?
thx,

Re: Model tunning and K factors
LTE900 K factor is the same as GSM900.

crca2010, really? may i know that u have experience this before?

Re: Model tunning and K factors
In Hata derived models the K factor is linked to the frequency not technology. Hence, K factor for 900 is the same for both.

I hope this equaion will be helpful:
K (for the new band)=k (for the tuned band) + 20 log(new band/tuned band)
If you like it, please add it to my reputation.

Re: Model tunning and K factors
in my experience, u can do it
before when u calibrate k2 to k7 for 900 -1800 are fixed before calibarate
and find k1 for each frequency band.
if u like this, give reputation pls
