Dear Pix,

Thanks for your response ๐Ÿ™‚

Related to hopping channel, I want to share about our frequency planning in my network.

Exmple, FLP GSM

FLP 1×3
For BCCH : 107 – 124
Guarband : 106
For TCH: 88 – 105
Sect-1 88 91 94 97 100 103
Sect-2 89 92 95 98 101 104
Sect-3 90 93 96 99 102 105
MAIO Sect 1 : 0 2 4
MAIO Sect 2 : 1 3 5
MAIO Sect 3 : 0 2 4

Those are my network FLP planning.

What do you think? Is that frequency allocation secure enough from interference (MAIO)?

Then, what your sugestion (Activate MAIO Hopping more than 4 …), i haven’t tried it, but what I’ve tried was like this :

Cell A Sector -1 :
Old setting of MAIO : 0 2 4
OLD MAlist : 88, 91, 94, 97, 100, 103
New MAIO : 4 6 8
New MAList :88, 91, 94, 97, 100, 103, 107, 113, 119, 122

And that’s working! ๐Ÿ™‚ I didn’t add MAIO up to 4 or more than 4, but added MAlist and changed the MAIO period only.

In your suggestion, we added new MAIO or change the MAIO with hopping channel more than 4. So how should I arrange the MAIO without adding the MALIST? If we set MAIO 0,2,3,4, then the hopping channel is too close (impact on interference). Any Idea brother Pix? Well, what’s your suggestion towards my network FLP allocation?

I would be grateful to discuss it with you and all experts in this forum ๐Ÿ™‚

Best Regards,

Paul
