Having hard time calculating S & L from SLIV

 Having hard time calculating S & L from SLIV 😩

no more:

S = mod(SLIV, 14)

L = rounddown(SLIV/14,0)+1

if calculated S+L > 14 then apply this correction

Corrected S = (14-S)-1

Corrected L = (14-L)+2

A couple of examples:

SLIV = 59

S = mod(59,14) = 3

L = rounddown(59/14,0)+1 = 4+1 = 5

S+L = 3+5 = 8

Hence no correction needed 😊

SLIV = 53

S = mod(53,14) = 11

L = rounddown(53/14,0)+1 = 3+1 = 4

S+L = 11+4 = 15

As S+L > 14, apply the correction

Corrected S = (14-11)-1 = 2

Corrected L = (14-4)+2 = 12

Unbox your boxed KPIs with FreTSO Pyramid

RF dashboards need modernization just like Technology 3G/4G/5G. when have a single Box of technology at sites, our dashboards were serving the purpose quite well but as soon as the number of Boxes increased at our sites so did the number of dashboards in one-one fashion making global view of the site difficult and hence the impact of changing one parameter in one technology to the entire site was invisible.
now we need to unbox the frequency layer from each of the boxes and have ONE dashboard of KPIs with respect to Frequencies (the most scarce and expensive resource of the cellular network). And FHO grid be an inherent benefit of this model as well. In one of my previous blogs I have already mentioned FHO (Frequency-based HO) Grid that can act as a traffic management KPI.
In this way we can start taking proactive actions to manage RF resources to cater for 10s of new services expected in 5G and beyond as we would be able see the consumption of RF resources at top level on daily basis.

DSS stands for Dynamic Spectrum Sharing
OEM stands for Original Equipment Manufacturer
FreTSO stands for Frequency Technology Service OEM

Freq HO Grid KPI deserves to be on the RF dashboards

The heart and soul of a cellular network is neighbor. And that’s the reason that we HOSR as one of the major KPIs. Until now we are measuring HO with infamous intra-eNB and inter-eNB HO KPIs. And in way its logical as well that whenever we integrate a new site we need to measure its HO activity within the site and as well as to its neighboring sites.

Now a days the major issue is capacity and to meet capacity we often add carriers and take the benefit of carrier aggregation as well to meet the capacity demands.

So the HO activity is increasing exponentially due to multiple number of carriers (frequencies) being transmitted from single site. And intra-eNB and inter-eNB HO doesn't offer such granularity as they are much more equipment oriented.

And we cannot have HO KPIs with every other neighbor in the form of a grid as well because every single cell has hundreds of neighbor relations.

Since now we usually add/delete frequencies in our existing sites and they stay within range that we can view them in the form of a grid.

This Grid can be used as a measure to evaluate traffic management settings and that alone can be major reason to have this grid on your RF dashboards in addition to other benefits you will be getting, like how good or bad new additional carrier (frequency) is doing with existing carriers from mobility point of view. And hence we can call it traffic management KPI as well.

We can have a couple of filters on top of this grid like one for HO related (like preps/executions/execution failures) and other for geographical area related (like cell/sector/site/cluster/market/region/nationwide level)
