Question: I need COFDM-904T work on 1080i 50 at least at 8-10Mbps
Answer: It is no problem.
Question: Can I set manually all the parameters by myself?
Answer: If you add PA (booster), then you can not; If you don’t need PA (booster), then you can (PA is hardware, if you change the setting, hardware should be adjustable)
Question: Which is the max frequency value we can set?
Answer: 900Mhz, Need higher, please choose COFDM-902T
Question: If the band range is 300-900 I will tell you exactly 4 ones in between to set for me, then I will need constant data rate at 10 Mbps, modulation at 16QAM, FEC at 1/2 and Guard Interval at 1/32. Encoding at 4.2.2 if possible instead of 4.2.0, 200 Meters (NLOS) Non-Line Of Sight and 500 Meters (LOS) Line Of Sight. RF power at 500 mW, remember, data rate MUST be fixed (not variable) at 10 Mbps, try this setting and let me know how it works (better if you can forward me a short video directly recorded from the HDMI output of the receiver – NOT SHOOTING A MONITOR SCREEN! At least we need 27dbm
Answer: OK, we can do the above sample if you confirmed.
