I have gone trough an interview for Ericsson and one question has confused me.I hope you people will help.The question was as follows.
Which value for HSN we do not use worldwide from the range of 0 to 63.
Can anybody answer,7th August 2007 at 13:39 #48600PixGuest
0 ! because zero is cyclic hopping, and it has no benefit. between 1 and 63, it is random, so the risk of collision is minimal (and random).8th August 2007 at 05:09 #48601JhaGuest
I had answered this but he urged that there is one value of HSN except 0 which is not used.8th August 2007 at 07:12 #48602pixGuest
ok… i can check later on… what a very weird question to ask during an interview !!9th August 2007 at 03:35 #48603BhanuGuest
Hi As far as i know, it is 11(or may be a3 but surely only one of them)Nut it is in Ericsson, In Motorola system we are using all.9th August 2007 at 05:32 #48604vivekGuest
I think that this value is 32(mid value) as this value is used for synchronisation.
This is sure that the value is 32 but for the reason i am in a bit of doubt.
So if anyone comes across the perfect reason do let me know.9th August 2007 at 09:12 #48605Amit AgarwalGuest
It is obviously 0 as it would result in cyclic hopping. Please verify it and let me know

As 0 is used for Cyclic hopping so it is not in question..8th June 2008 at 04:45 #48607ahmadGuest
we have motorola
we use all HSNs!!8th June 2008 at 11:13 #48608AbdelGuest
In Huawei and ZTE we use all. since every value between 1-63 is random it will do the work we need.8th June 2008 at 16:19 #48609DhinaGuest
i have a doubt.Isn’t there already a planned sequence for hopping.I read that there will be table in MS and BTS that have the sequences and the HSN tells which hopping to use.
can any one please explain Hopping with HSN and MAIO,well may be with an example.9th June 2008 at 04:49 #48610johanGuest
we use also huawei and zte but 0 is for synchronization but 1-63 it is value for HSN which we can avoid collision9th June 2008 at 06:36 #48611pixGuest
0 is not for synchro… synchro for what ? 0 is just an HSN that follows a cyclic law.10th June 2008 at 04:56 #48612vivekGuest
how can the value 0 can do synchronization….??? kindly explain..
as per my knowledge 0 is used for cyclic hopping only…nothing more than that…!!!11th June 2008 at 04:02 #48613AbdelGuest
I even didn’t notice I was writting synchronization I meant cyclic. Sorry for that.
