Re: [WISPA] Help Me Understand This WiMax Show We Had...

Hi Sam

we have some operators in Italy using WiMAX in licensed and unlicensed. 
In licensed it works well, in unlicensed it woks not so well

I have heard some marketing guy saying things like it works till 20 
miles and it gives you a lot of bandwidth which is technically wrong 
but it's a good commercial white lie. the reality is it works 
till 20 miles OR it gives you a lot of bandwidth meaning that yes you 
can do 20miles but at lower efficiencies (=bandwidth) or you can have 
high bandwidth if you have near customers with a good signal.
WiMAX does not do miracles

Lately I have heard that some WISP/operators are abandoning WiMAX and 
moving to LTE or dual stack WiMAX/LTE because frequencies are usually 
technology independent and LTE seems more supported by some vendors 
and the new marketing magic word.

The problem is that devices are really expensive so you must have some 
really good reason to convince the customer to buy that thing or you 
must be sure that the customer will never abandon you.  So the WiMAX is 
not working in the WISP unlicensed business because if you have clean 
channels you can give the same service with unlicensed 5Ghz and at lower 
prices.

Indeed for the unlicensed market there are two options:

1) the channels are empty/clean and you can do whatever you want even 
with a 5Ghz device
2) the channels are dirty/noisy and WiMAX does not work well there

Regards


 Today we had a company come to us pushing wimax. Admittedly I've never
 used wimax, nor do I know a lot about it. From what I can see looking at
 Google images of the technology and how it's deployed, it looks no
 different than the PtP and PtMP that we all use with 900 MHz, or 2.4 and
 5.x GHz.

 Is the only advantage to wimax the presumably clearer and less-used
 frequencies upon which they operate? I had (evidently mistakenly)
 thought that perhaps wimax was a code word for some sort of mesh, and
 that's how it achieved NLOS service. However in looking at the network
 layouts on Google, it doesn't look like that at all. Rather, it looks
 like that add another AP to get around the obstruction(s), and simply
 backhaul it to an intermediary AP/tower to get it back to the PoP.

 Thanks
 Sam

All numbers can be ported, IMO.  If you would like me to pull them for you 
hit me offlist.

 We've found that we can't get anything ported here in Alaska... something 
to do with agreements that Alaska Communications Systems and GCI did.

 Ah, the world-famous Kasson and Mantorville Telephone Company! :-)  Those 
tiny ones can be tough.  They are in LATA 620 but subtend the Plymouth 
tandem, which is in Minneapolis LATA 628. Odd, but there are a number of 
those exchanges in the Rochester LATA. That tandem belongs to Minnesota 
Equal Access, a sort of CLEC that runs a tandem on behalf of many small 
ILECs.  Maybe they could help you.

Their prefix codes are local but a CLEC generally needs an interconnection 
agreement with them, and I doubt many have them. Just not worth the bother. 
 But I do see  Mantorville numbers belonging to Sprint-CLEC, MCC, and 
bandwidth.com. So they may have arrangements.
507-528 507-527

  
 Those are Frontier Citizens, the old (not ex-GTE) rural ILEC.  Portable 
but not pooled. Both remotes of the Kenyon switch, on CLQwest's Owatonna 
tandem.  Jaguar Communications is the only CLEC with Claremont numbers; 
Sprint and MCC have West Concord numbers.

As a general rule, any rate center's numbers can be made portable if they 
aren't already so.  It can worst case take six moths to implement.  But 
that was usually done long ago.

However, in order to port a number into a rate center, the carrier (CLEC) 
needs connectivity to the tandem switch that serves that rate center, which 
may belong to the ILEC in that rate center, or a third ILEC, not the one in 
the bigger exchange next door.  If you tell me the rate centers in question 
I may be able to determine that for you.  CenturyTel[/link] is notorious 
for being uncooperative, hoping state regulators let them bend the rules 
their way.  And some rural ILECs think they're exempt from interconnection 
rules, though they're not.  So it would not be surprising if the underlying 
CLECs just don't touch those RCs.   On Thu, Mar 27, 2014 at 3:06 PM,

Subject: [WISPA] Number's that can't port to VOIPWe have a customer on 
fringe of a rural Century Tel area and both of our voip providers came back 
saying they were unable to port the number for us. Are there remote areas 
where you still can't port a number? Is there a way to find out if anyone 
can port this number? Like a master list or database I can search?
