Efficient Use of Spectrum


Recommended Posts

Much has been written about Network Vision and its components. Multi Modal towers, 1x Advanced, DO Advanced, LTE etc. So Sprint isn't just rolling out LTE, in fact it has been stated that NV technology will make Sprint's network future proof. We know that Sprint will spend in excess of $7 billion on this massive project that will help maximize the efficient use of its spectrum holdings.

 

Verizon and ATT are currently building out their LTE networks and while doing so they are touching almost every one of their towers. Does anyone know if they are doing anything to help maximize their current spectrum holdings?

 

This question is a result of reading an article on Broadband Convergent. http://www.broadbandconvergent.com/news/mobile-operators-creating-artificial-demand-capacity

 

Should a Wireless Network Operator show that the company is maximizing its efforts to use spectrum in a most efficient manner before being allowed to participate in future auctions?

When you are talking about "they" are you referring to Verizon and AT&T? Because if you are talking about Sprint then I would say ..Yes they are making efficient use of their limited spectrum that they have. Most people on this site know how Sprint is showing that they are making the most of its spectrum through the 800 Mhz refarming plan.

 

In terms of Verizon and AT&T, I would say "No" they are not making the most efficient use of the spectrum since that they haven't even tried such things as "Wifi offloading" on their network as well as deploying "small cells". Also Verizon is not looking to refarm any of its current 850 or 1900 Mhz spectrum first before resorting to buying more spectrum on the market. I would say the same for AT&T. They have a crap load of 850 Mhz and 1900 Mhz spectrum that could be refarmed before trying to starve the competition.

 

Tmobile is even doing a better job of making use of their spectrum by refarming HSPA+ to 1900 Mhz by kicking out 2G EDGE folks and of course repurposing the AWS spectrum for LTE.

The easiest way to objectively measure this is to look at how many subs each carrier has per MHz of bandwidth-- if you want to see an "average" or overall efficiency. I've done some math below that may shed light on this.

 

AT&T has an average of 79 MHz serving about 100 M subscribers or 0.79 Hz/sub

Verizon has an average of 88 MHz serving about 110 M subscribers or 0.8 Hz/sub

Sprint/Nextel (alone) has an average of 53 MHz serving about 55 M subscribers or 1.03 Hz/sub

Sprint + Clearwire has an average of 195 MHz serving about 68 M subscribers or 2.87 Hz/sub

 

The source for the licence info is below. Using this average national licensed information and the most recent subscriber figures, it would appear Sprint is more of a spectrum hog than the big two-- this may seem counter-intuitive, but you have to consider the number of subs. I know in my market, Sprint has been sitting on 40 MHz of PCS and 14 MHz of ESMR and they run 2-3 TOTAL CDMA carriers (using about 5-7.5 MHz / 40 MHz PCS band) conversely Verizon runs 9 cellular and 3-4 PCS carriers along with their 10 x10 LTE here, so they use 55 MHz of their 97 MHz here.

I didn't intend that Sprint be included in "they". I know about Sprint's efforts to make the most of what they have. I don't know of any efforts by Verizon and ATT to maximize the use of their holdings. In fact while crying for the feds to release more spectrum Verizon is saying they have plenty without having to refarm http://www.dslreports.com/shownews/Verizon-Weve-Got-Plenty-of-Spectrum-Thanks-118417

Wow! The knowledge on this site amazes me. Thanks

But on the other hand in even some of the largest markets Verizon and ATT are not using all of there spectrum.

 

Look at Chicago, Sprint is maxing out there spectrum holdings while ATT and Verizon are using less than 50% from everything I have read.

 

Also stating national averages of total spectrum does not show a true or realistic representation of the true spectrum hogs.

 

Sprint and T-Mobile are currently using each of there spectrum bands they own ATT and Verizon have entire free and clear bands sitting in a warehouse just so the competition can not use it.

 

Also you have to think about free and clear usable spectrum vs spectrum already in use by a network.

 

Just some food for thought.

My thought process has been that Sprint is actively touching each tower, essencially "rebuilding" or upgrading each one. While AT&T and Verizon are rolling trucks to add panels and equipment to existing sites, not changing out the base stations or such.

    • Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.
    • Mike if you need more Dish data, I have been hunting down sites in western Columbus.  So far just n70 and n71 reporting although I CA all three.
    • Good catch! I meant 115932/119932. Edited my original post I've noticed the same thing lately and have just assumed that they're skipping it now because they're finally able to deploy mmWave small cells.
