Goodbye Nextel...

oh well around here in Reading the wait time was def at least 1 second no lie at all.....

 

I didn't see this earlier..... but Hmmmmm the FCC did what?

Incorrect my friend. With the current FCC spectrum allocation and utilization plan they themselves didn't do anything wrong persay. The specific section of 800mhz that Nextel occupies is licensed strictly to trunking radio systems which means every site has to have every frequency licensed.
The problem arose because the equipment the PS agencies (And other trunked systems) couldn't reject the much higher power Nextel transmissions, in many cases only a few khz away. With a typical Nextel site transmitting roughly 500watts EIRP a handheld radio 200ft away simply didn't have the front end rejection to let it ignore the Nextel transmission's.
Couple that with the high noise floor on the mobile uplink side due to sheer number of users and any repeater receiver out there with a loosely tuned filter will have a hard time distinguishing incoming transmissions. It's not a 100% Nextel problem nor a 100% Repeater owner problem, it's a joint responsibility and both sides need to work together which is what we're seeing.

Also, on a side note look up how Nextel was created and built and you'll see how the FCC probably didn't even see it coming.

 

500 watts? Is it really set up for that? The few Nextel techs I have run into have said there set up for 100 watts before the combiner and 50 watts at the antenna. The Nextel techs up here in Northern Michigan are complaining that the Sprint engineers have cut the out put power in half.

Any truth to this?

 

everyone points fingers at everyone else......but in the end who did it doesnt matter and they all just need to work together to get the job done..........gosh didnt they watch bob the builder and barney when they were growing up??? :biggrin:

 

No way we had much better shows to watch, when we couldn't be outside, like the little rascals ect...

It is a big deal since Sprint/Nextel is the one paying out big money for this.

 

It depends on your locale, though my 500 watts was stated in EIRP (Sorta makes it look big, ya know? )

Average physical radio is self is putting out 30-40watts then toss that through a combiner (typically at least a three way) and then out to (typically) a gain antenna. In my area it's rare to see one put out past 40watts direct from the radio.

 

Kinda of what I figured. Our old Lucent TDMA/Analog is something like that.
The Linear Amplifier frame puts out 250 combined watts but the power is shared by the radios so you have to divide the number of radio by the goal output power. So if its a sectored site you usually need two Amp Frames per sector which make a huge cell site, usually 6 frame minimum.

 

Speaking of the Nextel phase-out, the recording that says "Please hold while the Nextel subscriber you are trying to reach is located" is still there. They haven't changed that to Sprint yet.

 

What a waste of resources! Why the hell even deploy Kodiak if is going chew up a time slot. The sub my think it’s cheep because it a glorified walky-talky but there’s TCH’s locked into a simplex audio exchange. Hell if you got a cell chock a block full of resources by all means, but I’d rather have a real call established. During a PPT connection with Kodiak and it ideal do you figure it into you cell erlang figure?
