How interference signal is estimated at the cell edge? Since mobile phones are continuously moving, the interference signal level also keep changes with time.
What should be the periodicity of estimation ? Is this information used in handover process ?
With 4G LTE, some services will run on the 800 MHz spectrum band. This band is close to the frequency used by certain Freeview services. Because of this proximity, viewers who watch Freeview and live close to a new 4G mast, could experience interference. Symptoms for those affected might include a loss of sound, pixelated images or even the loss of all channels. Uplink interference in 4G is another form of interference. Co-channel interference (CCI) and inter symbol interference (ISI) shall be the other forms. If 4G cell phones move into the newly available lower frequencies at around 600 MHz cable TV will experience interference.
A recent study demonstrated that electrified rail arcing on pantographs could interfere with trackside signalling and control. The emissions were remarkable in the upper UHF to at least 1500 MHz. This suggests that LTE systems in the vicinity of electrified rail may be at risk for uplink interference in the 600 - 900 MHz bands.
4G LTE Interference may threaten the GPS timing input as well

AR Reddy in 4G LTE 700 interference RSSI with TNT 700 external interference need TMA (Tower Monted Amplified) L700/L800 + Filtre LTE/TNT
Ahmed el Mahjoubi AR Reddy Abdul Basit , Gents,
Can I have LTE RSSI equation for macrocell and femtocell??
Thank you in advance,
