Hi Guys,

Does anyone can differentiate staggered and block frequency plan. Also please provide the advantages and disadvantages. It would be better if you have experience both sides of frequency plan.

Staggered MAL are like this

Sector A: 593, 596, 599
Sector B: 594 , 597, 560
Sector C: 595, 598, 561

Blocked MAL are like this
Sector A: 593, 594, 595
Sector B: 596, 597, 598
Sector C: 599, 560, 561

in urban area=block fp preffered.

in rural-staggered fp is gud.

Maahson,,
Is it permitted to put the adjacent frequencies in the same cell? From my understanding, one should avoid adjacent frequencies in same cell. Please clarify.

This is not problem, just make sure they are not in use at the same time.
Use proper MAIO control: or just make MA lists much longer as nr of TRX, so
probability of interference (using both on the same time) is low.

If you do it wrongly, take care of uplink interference. Downlink is fine, so it is hard to
detect - you might scan for some wierd complains to the call center.

On original question: it depends on number of frequencies available.
I would try to avoid staggered as much as possible, unles you have
low nr of frequencies and want to hop over wider bandwith.
In that case, consider reuse 1 as an option, it might work better.

One more note: while comparing different syn hop approaches, do not trust
stats too much. Average Q/SQI without information on distribution is not really
reflecting user experience.

Actually there are adjacent channels in the MAL but at any given time no adjacent frequencies are used in a site. This done by assigning MAIO in below fashion:

Sector A: 0, 2, 4
Sector B: 1, 3, 5
Sector C: 0, 2, 4
