How to Spot Sprint Antennas and RRUs (Ericsson)

Recommended Posts

29xvoti.jpg

Ericsson RRUS31 B25 + RRUS11 B26

These are the newest and greatest remote radio units to come from Ericsson. 

The new Ericsson RRUS31  B25 should be fairly distinctive compared to the earlier RRUS11s and now the RRUS12s being deployed by ATT and Verizon. One of these new RRUS31s can do the job of two earlier RRUS11s thus reducing deployment costs for Sprint and complexity in deploying new sites and making it easier for users to spot as there are now 4 jumpers coming out of one RRUS31 rather than two from each RRUS11 that Ericsson originally deployed. 

All future deployments will be utilizing the new Ericsson RRUS31s. In addition Ericsson are sending crews to their original deployments and swapping out older RRUS11s for these new RRUS31s due to the aforementioned fact that one RRUS31 can do the job of 2 RRUS11s. Weight savings will be significant at sites where there are 4 or 5 RRUS11 B25s that can be replaced by one or 2 RRUS31s. The Ericsson RRUS31 deployment project is known as the 65 Mhz Project.

Ericsson High Capacity / 4x4/2 MIMO Deployment
Note the additional antenna + PCS radio.
Previously Ericsson utilized additional PCS radios and used RF combiners for high capacity setups where they utilized three or more PCS radios. This new setup will utilize a completey new antenna + radio set just like Samsung and run 4x2 MIMO on the LTE antenna / radio set.

A standard Ericsson Network Vision 1.0 site with 3 RRUS11s where two are dedicated to PCS and one to SMR.  

This type of setup is no longer deployed or utilized in new sites. Existing sites will be slowly converted to newer RRUS31 B25 via the Sprint 65 mhz project.

so whats the purpose of each of the 4 boxes on the back of each antenna?  is it just an ericsson antenna specific thing?

Those are the RRUs. Remote Radio Units. See the FAQ for a detail explanation.

 

They are not an Ericsson thing. All of the OEMs use them. Though they all look different, as each company develops their own technology. Samsung uses 2 RRU(H)s, as does Alcatel Lucent.

so perhaps a stupid question, but as i seen from the map samsung is the northwest antennas, but i have seen a few that look like these ericson models?  Do other carriers have deals with ericson up here in the northwest?  or do they tend to stay in the same territory for each carrier?  like does verizon use samsung/ericson/altel lucent as well?  or do they have their own manufacturer?

Has anyone seen panels like these used in an Ericsson NV deployment? I found these staged at one of our few remaining non NV sites in Louisville, KY. These are slightly different than the usual panels.

 

These are Andrew panels, with input ranges of 698 MHz - 896 MHz and 1710-2360 MHz.

Sprint uses off the shelf equipment from the antenna manufacturers. Antenna manufacturers try to include as many frequencies as possible to support a wider client base and limit development costs for multiple different antennas when one can do everything that needs to be done.

OK, so hope is not lost yet. I was wondering as there are three other carriers on this tower and these are different than most of the other panels used for Sprint here. Hopefully these get mounted soon.  :tu:

Remember antennas are agnostic. They can broadcast whatever as long as it's in the supported frequency range and are hooked up properly to a radio.

It appears I was wrong, this was for another carrier. Went by the site again today and they were actively working on the bottom rack, Sprint is second from the top. Oh well, this site goes back on my watch list.

I also found a site, which has been marked in the sponsor area as "In Progress"...with the new RRUS31 being used.

 

I just happened to drive to the site out of the blue, and they were working on it. Talk about your ironic luck...

 

I hope this site goes live soon, but here's what I got yesterday and today (No change that I can see between today and yesterday, so I'm not sure what work they were doing)

Less weight for similar capability. Potentially stronger signal at the edge but other than that not much changes except you drop a lot of weight from removing two or three old rrus11s which allow you to have more rooms for activities... You know... Like installing a new radio head and antenna.

Spotted a crew doing a RRU swap today, I believe it was Goodman Networks, they were working on the N and SE facing sectors, could only get LTE on the SW facing sector of the site.  I'll try to get pictures tomorrow depending on the weather and if they have finished up.

I found a NSN/Ericsson Spark permit in my area which, in addition to adding 2.5 equipment and replacing RRUS 11s with RRUS 31s, also adds new 1900 MHz antennas -- APXVSPP18-C-A20 on the alpha and beta sectors, and APXVRR13-C-A20 on the gamma sector. The original NV antennas also remain, so this may be the first indication that Sprint will actually be using the 4x2 MIMO capability of the RRUS 31.

Yep. Looks like they're abandoning the Rf combiners in high capacity sites for another set of antenna and radio heads like Samsung.

No. This is just another way to deploy high capacity sites. Samsung has been doing this type of setup since the beginning.

      Sprint 4G Rollout Updates
      Friday, April 20, 2012 - 11:31 AM MDT
       
      Is there a "spectrum shortage?" Those two words send shivers down the spines of wireless industry executives. New services demand ever more spectrum, and, the story goes, there simply isn't enough spectrum available. An Internet search engine will easily find hundreds of thousands of links to the term "spectrum shortage." Many claim that it will be the downfall of America.
      The dwindling availability of a finite resource that can't be seen or touched threatens to possibly disrupt the mobile lifestyle that virtually every American has embraced. Dropped cellphone calls, delayed text messages and choppy video streams could become more frequent occurrences because the airwaves on which that data travel are nearing capacity at a time when mobile usage shows no signs of slowing.
      Federal regulators and industry players are searching for ways to fend off the supply-and-demand collision. Dish Network recently acquired a large block of vacant wireless spectrum that pending regulatory approval could be used for mobile broadband services.
       
      Short-Term Plan

      AT&T tried to merge with T-Mobile to solve its own capacity problem. It wanted to get its hands on T-Mobile spectrum. Still, that would have been only a temporary fix at best. Remember all the terrible stories about the quality of AT&T's wireless data network over the last few years? They say they simply don't have enough.
      The reason is that during the last few years, smartphones like the Apple iPhone and the many devices running Android emerged, and wireless data traffic grew like crazy. This problem jumped up and bit AT&T in the rear end. Suddenly, so many people were sucking so much data that the network could not handle it, due to spectrum shortage. Spectrum is like the size of the hose, and a wider hose is needed to carry more data for more customers.
      A couple good things are suddenly happening that may give carriers a little time to solve this increasing problem. Perhaps Verizon starting to sell the iPhone last spring has something to do with it. If so, then now with Sprint selling the iPhone, AT&T will have more breathing room, at least temporarily. That's the good news. However, that reprieve will only last a short while before the exploding smartphone and wireless data growth catches up. Then the other carriers will be faced with the same problem that's confronting AT&T.
      In the first quarter of 2011, the amount of data the average smartphone user consumed each month grew by 89 percent to 435 megabytes from 230 MB during the same quarter in 2010, according to Nielsen research. That's up from about 90 MB in 2009. For reference, the average size of an MP3 music file is about 4 MB.
      "Texting has always been traditionally viewed as a lightweight consumer of bandwidth, but if I start adding videos and pictures to my texts, that also starts consuming more bandwidth," said Tom Cullen, an executive vice president with Dish. But the primary growth driver will be video. Consumers can go through 5 gigabytes a month simply by streaming 10 minutes of standard definition video daily, he said.
       
      Data use is skyrocketing
      Data from the FCC indicate that more Americans are looking at their phones rather than talking on them. In 2009, 67 percent of available spectrum was utilized for voice and 33 percent for Internet data. Those percentages are now at 75 percent for data and 25 percent for voice. With each new iPhone release, data consumption grows. The iPhone 4S eats up twice as much data as the iPhone 4 and three times as much as the iPhone 3G, according to a study by network services firm Arieso. The new iPhone features Siri, a bandwidth-heavy voice recognition feature.
      The FCC estimates the U.S. will face a spectrum deficit of 90 MHz in 2013 and 275 MHz in 2014. To address the crunch, the federal government hopes to unleash 500 MHz of spectrum currently used for other purposes for wireless broadband by 2020. To put that figure in perspective, there is currently 547 MHz of spectrum allocated for mobile services, and AT&T and Verizon each own about 90 MHz.
      The government plans to hold so-called incentive auctions, which will try to lure spectrum owners such as TV broadcasters to sell their licenses. Verizon Wireless has agreed to purchase spectrum from a group of cable-TV companies. Sprint has expressed interest in working with Dish, which acquired the bulk of its 45 MHz of spectrum through two deals for bankrupt satellite technology companies. Dish chairman Charlie Ergen has said that the satellite-TV provider would prefer to partner with an existing wireless carrier on a high speed, 4G network. In response to recent comments by Sprint Chief Financial Officer Joe Euteneuer about the company's interest in working with Dish, Cullen said other wireless carriers are in the same situation. After failing to acquire T-Mobile, analysts expect AT&T to make a play for Dish, a long-rumored merger partner.
      As for T-Mobile, perhaps the most logical buyer is CenturyLink. T-Mobile's German-based parent company has indicated that it might exit the U.S. market. CenturyLink, which acquired Denver-based Qwest last year, is the third-largest landline phone company but does not own a wireless service, unlike the top two, AT&T and Verizon.
      Carriers are trying to offload as much traffic as they can to Wi-Fi networks, which ride on unlicensed spectrum. In some areas, they're installing picocells, which are smaller cell sites that can help boost capacity in dense areas.
      Finally, they're spending billions of dollars on LTE networks that use the airwaves more efficiently. Verizon and AT&T already have 4G LTE networks in place, and Sprint is moving to the technology. Dish says it hopes to enter the mobile broadband market with advanced LTE technology by late 2014 or early 2015. If Dish were to also offer voice service, it would come through VoLTE, which is similar to Voice-over-Internet Protocol (VOIP) phone services. Dish still needs the FCC to drop a condition tied to its spectrum that requires devices to have the ability to communicate with satellites, not just ground-based cell sites. The rule-making process that will likely remove the requirement is underway and could be completed by summer's end.
       
      Is there really a shortage problem?
      The problem, analysts argue, is that the operators that control the greatest amount of unused spectrum may be under-capitalized or unwilling to build out networks to use the spectrum. "We do not believe the U.S. faces a spectrum shortage," Jason Bazinet and Michael Rollins wrote in their Citigroup report. "Too much spectrum is controlled by companies that are not planning on rolling out services or face business and financial challenges. And of the spectrum that is being used, 90 percent of it has been allocated to existing 2G, 3G, and 3.5G wireless services by larger wireless carriers, such as AT&T, Verizon Wireless, Sprint Nextel, and T-Mobile USA.
      In total, U.S. operators have licenses for about 538MHz of wireless spectrum. Only about 192MHz of that spectrum is currently being used. Most of the unused wireless spectrum is owned by companies such as Clearwire, LightSquared, and Dish Network. But so far, LightSquared has been stopped and the other companies have been slow to build networks using their available spectrum.
      "There is definitely a mismatch when it comes to spectrum in the wireless industry," said Paul Gallant, an analyst with MF Global in Washington, D.C. "There are some companies that have spectrum, but they're struggling financially. Or they aren't quite sure what to do with the spectrum. And others that have the money and business model, but need the spectrum." The move to 4G is very important for these operators because it offers them a more efficient way to deliver service. 4G LTE uses the available spectrum roughly 700 percent more efficiently than the 3G wireless technology EV-DO. Carriers will soon be refarming 3G spectrum to 4G LTE in several years.
      A key factor in encouraging efficient use of spectrum has been largely overlooked in carrier boardroom discussions. Wireless providers can add capacity, without obtaining more spectrum, by adding more and more cell sites. Additional cell sites in spectrum constrained areas allow the same spectrum to be used by even more consumers, as well as adding picocells and microcells to denser population areas. So far, the carriers have not expressed too much interest in this method due to additional capital expenditures and overhead. Their strategy is like what Microsoft, Apple and Google have used. It's just cheaper to buy what you need than to invest the time and energy to do the actual work.
      So what can the wireless companies do? To some extent, re-farming their existing networks will help. But so will finding ways to use other spectrum. For example, only T-Mobile lets users make phone calls using Wi-Fi, yet most of the mobile devices available from carriers have this capability; the carriers just don't enable it.
      Allowing Wi-Fi calling could unload millions of voice and data users on to alternative networks and ease the spectrum crunch, at least to some extent. Encouraging VoIP use would also help for two reasons. VoIP doesn't require a lot of bandwidth, and it means that the phone in question uses only the data spectrum, not both voice and data while this is going on.
      These points illustrate that the carriers do have options beyond just buying up spectrum. They can offload more wireless traffic than they do now, build more cell sites into their networks and they can allow the use of other types of communications. While the spectrum crunch isn't going away, that doesn't mean that the process can't be slowed.

      Sprint 4G Rollout Updates
      Tuesday, January 31, 2012 - 7:46 PM MST
       
      Since last fall, there had been talk of a Samsung Galaxy Nexus launching on American carriers other than Big Red. Sprint has finally announced several weeks ago that it is the another vendor slated for release in the U.S. Suffice to say, many of us out there, especially those adverse to heading to Verizon and paying its premium prices, are excited about the impending release.
      The good news is that Google could be working on an updated version of the Galaxy Nexus. It has unofficially been dubbed the Galaxy Nexus Plus. There is much anticipation that it will be released before Sprint turns on LTE this summer. It’s not the first time an OEM has refreshed a device and re-released it to the market place, which works to our advantage. It’s rumored that the new Galaxy Nexus will have either a 1.5 or 1.8 GHz Texas Instrument OMAP4670 dual core processor. This would be a significant upgrade from the 1.2 GHz dual core processor found in the current Verizon version.
      We don’t know anything about official specs, but it’s also rumored to have an 8 MP camera. This is a noteworthy upgrade to the 5 MP shooter on the Verizon model (which has been lauded by many techies). We already know that the Sprint model will come installed with Google Wallet, per previous announcements. Some rumors also point to a beefier battery as well. The phone should have all the other features that’s on the current Galaxy Nexus, so now all we have to do is wait.

      Sprint 4G Rollout Updates
      Monday, June 25, 2012 - 4:27 PM MDT
       
      As technologies advance, the equipment to use the technology must advance as well. With the upcoming release of 4G LTE in our area (Houston), new equipment will be required to be able to use it. Although Sprint will have numerous data devices to handle the usage by the end of the year, only the Sprint Tri-Band Modem will be available at the rollout of the 4G LTE service.
      Due to the enormous dependence my business has on accessing data in a mobile environment, plus the great increases in data speed available with 4G LTE, this makes getting access to 4G LTE imperative to me. I depended heavily on the Sierra Wireless data devices when I started this business 7 years ago for my source of a reliable method of mobile data transmission. This relationship continued on until the release of the original Hotspot with the 4G service in my area.
      At one point, I was so displeased with past models, that I had sworn I would never buy another Sierra Wireless device as long as I live. This conclusion was reached after having numerous issues with previous hotspot models. There were so many problems that it seemed as if the device was never even tested on the networks it was to be used on. Also Sprint actively blocked reviews of the device, likely to not hinder sales in spite of the problems.
      My need for a new device with both WiMax and LTE capability outweighed my outright dislike of Sierra Wireless products. I proceeded against better judgment, and the Tri-Band modem was ordered even though the possibility of getting a substandard unit once again was always at the forefront of my mind.
       
      On with the show
       

      The official part number of the Tri-Band Modem is 803S. Along with the modem, I also ordered the SSX7077-V desktop cradle. I had to dig through a lot sites to find the information necessary to make this decision for my business. Much to my surprise, even though I was told the cradle was not available yet, I got a Sprint telesales person who was able to use the part number and find they had it in stock.
      Upon arrival I unpacked the unit and cradle...while holding my breath. The device that came out of the box was a pleasant departure from the previous Hotspots I had owned. Above is a picture of the device as it was shipped with all components. There was a small user guide as well but to get the real instructions the user guide must be downloaded from Sprint.
       
      Gone was the one piece blow molded plastic case which allowed no air circulation and caused the prior Hotspots to overheat quickly. Although the display is still too small for my aging eyes (it is actually the same display size as prior units) the change to the case makes it much easier to see in the interior of my van where the device will mostly be used.
      In this picture of the front you can see that there is a new button arrangement as compared to the older Hotspots. Also in the picture is the USB cable for use with the charger or to connect a computer, the AC to USB adapter, the battery and the battery cover. I opened the cradle, which was surprisingly inexpensive, and was delighted to find an additional AC to USB adapter which meant the cradle could be left in place without having to move the adapter around.
      As you look at the modem from the side you can see the antenna ports (the covers are open), the USB connector in the middle and the slot for the memory card. The round hole just right of the left antenna port is the reset button for the unit.

      Here is the same view with the battery and cover installed. Notice that the SD card slot is covered by the
      battery cover.
       

      The opposite side has two switches. The one on the left is a WPS setup button while the one on the right is a slider to mute the unit.
       

       
      The unit sits nicely in the cradle and looks to me to be a solution to help keep the USB port for the charger/interface cable from failing. This has been a major issue with the prior Hotspots. The case of the unit also helps support the USB port to take some of the load off of the circuit board.
      It took quite a bit of digging on the Sierra Wireless site to find out that the antenna ports are for the 4G WiMax band only. The cradle contains 2 5dbi omnidirectional antennas to allow full use of the WiMax network architecture.
       
      Initial testing

      The initial testing of the unit looks promising. The antennas in the cradle for 4G WiMax actually seem to get 3 – 5dBm gain in all conditions tested. The new unit has the ability to search the other bands for signals while staying connected. This allows less downtime between band changes. I notice a lot less disruption when switching bands.
      This unit has better reception on 3G and 4G WiMax than the previous hotspots and even the U600 USB modem I use as well. 4G WiMax is able to connect quickly even at 10% and the cradle has improved stability of WiMax and decreased ping times. For a short time I had access to Sprint 4G LTE as they were testing the towers in my area. The speeds were incredilbly faster. A 10% 4G LTE signal averaged 8.12Mbps download and 1.85Mbps upload. An 80% signal was able to get 35.8Mbps down on my best test and 22.1Mbps up.
      The upload speeds was very unexpected, and much higher than Sprint LTE smartphone devices have reported. This is likely due to much stronger transmit capabilities of the hotspot. I also discovered that when the modem is tethered the cable limits the bandwidth to approximately 20Mbps total speed. It will be interesting to see how it works in the 12 to 14 hour days of hot Houston Weather.
       
      First week in the field
      The Tri Band Modem got pressed into service a little quicker than planned, as my main unit went down with a bad transmission and the U600 USB modem with a Cradlepoint that was in this unit appears to have been damaged by the wrecker’s radio which runs on the edge of the WiMax frequency at 5 watts. The units have been sent in to determine cause of failure and for repairs but I think next time I will make sure all electronics are powered off before getting that close to a transmitter (OUCH!!).
      I am running the same routes in a rental van with the Tri-Band Modem that I normally use the other units on. There is less downtime in the signal gaps I am familiar with and areas where I have had signal problems in both 3G and 4G WiMax are much improved. I have yet to encounter any more 4G LTE signals but am looking forward to the service coming online soon. The unit seems to be running hotter than I would like with a fully charged battery but is actually cooler that the previous Hotspots. The temperature is supposed to soar over the next few days without the cloudiness we have had this past week. So it will be interesting to see if the overheating problems of previous models still occur.
       
      Week 2 – The True test
      The unit is getting worked really hard this week with temperatures outside up near 100 degrees. The GPS is useless with this kind of sun load as the unit will overheat if left in direct sunlight (as the instructions state) in about 20 minutes. The good news is that this is about twice as long as my original Hotspot will last. How anyone can make a unit that requires a clear view of the sky for GPS but can’t handle sunlight is beyond comprehension. A quick check of the Tri-Band’s temperature specs shows that the unit is only rated for 95 degrees. The prior Hotspot was rated well above the century mark but couldn’t even handle 90 degrees for any length of time. The crappiest laptop on the market will handle 105 degrees plus all day long. The true test will be my afternoon calls when the temperatures are high. Battery life has been about 8 to 9 hours which is far better than the prior Hotspots.
      The unit started overheating one afternoon. I can’t say I’m a bit surprised at that, but what is surprising is that it will run steadily as long as the air temp is below 98 degrees. This is a first for Hotspots as they always overheated well before the rated temperature spec. The bad news is the crappy overheat shutdown doesn’t turn off the unit before damage starts to occur, nor does it turn the unit off completely.
      Removing the battery cover seems to help air circulation and overheating some. The button lights are flickering after one overheating but the unit seems to be working fine other than this. It will be interesting to see what happens when it really gets hot here.
      According to the specs 4G LTE takes the least amount of wattage to run so it may not overheat as fast when using 4G LTE. I had the chance to try the modem in the old school 3G EVDO mode as one of my locations is 40 feet underground and that is all that is available at this location. I shut the unit down after 30 minutes as the unit was so hot you could barely handle it even though the temperature underground is around 70 degrees. I would not recommend trying to use this for any length of time if you want the Tri-Band to not overheat!!
       
      My Opinion
      Although Sierra Wireless has made some major improvement in the 3rd generation Hotspot, this is still a unit for the casual user. It is not designed to handle heavy use or outdoor summer temperatures for any length of time. It will be going in my climate controlled cabinet to protect it from the heat next week. I will let you know how it works when the temperature stays below 85 degrees. The improvements in connectivity, reception and stability are worth the investment. As long as you know and adjust your usage for the limitations of the unit.

      Sprint Nextel revealed their second quarter 2012 corporate earnings in a conference call to their investors today and S4GRU was covering for news on Network Vision.
      Network thinning of the iDEN network is complete, taking 1/3 of Nextel towers off air. The Nextel network was built to support 20 million subscribers, but was only supporting 4.4 million subscribers, so it could easily be thinned without [much] noticeable change in street coverage. Sprint also converted 60% of the Nextel subscriber loss into their Sprint subscriber base. Interestingly, they stated that Verizon has been the biggest poacher of subscribers leaving Nextel, grabbing 50% of former subscribers in the last 4 1/2 years. In that same timeframe, Sprint has grabbed 25%, AT&T 20% and T-Mobile 5%.
       
       
      On the Network Vision topic:
      4 additional cities will launch, including Baltimore, by the end of August.*Edit* Cities were disclosed VIA press release following the conference call. They are:
      Baltimore, MD Gainesville, GA Manhattan/Junction City, KS Sherman-Denison, TX  
      Over 2,000 sites are currently online with 12,000 sites to be online by the end of the year
      Network Vision towers are seeing 10-20% additional voice minutes usage per tower, overnight after activating Network Vision. This will equal roaming savings for Sprint, and ESMR will only increase that savings.
      CEO Dan Hesse confirmed that Sprint will be releasing the Motorola Photon Q "in the very near future." It will be a QWERTY slider "with robust business and consumer features." It will also be sporting world phone capability.
      Several hundred Network Vision sites are waiting for backhaul, and will turn on when the backhaul is installed, several hundred more sites have birds nesting on them and Sprint won't be able to turn them on until the birds leave, according to the conference call.
      Sprint sold 1.5 million iPhones during the quarter, even though other carriers saw slowing of sales with rumors ramping up that the new iPhone would support LTE. 40% of the iPhone sales were to new customers. They also stated that iPhone customers require less customer support and are expected to churn less than customers on other phones.
      Mr. Hesse confirmed that Sprint is not looking to change plans in the near future.
      Things are looking up for Sprint. This quarter saw their highest ARPU and their lowest churn rate to date. They posted a larger loss than Q1, but beat their revenue goals for Q2. For more detailed financial information, check the source link below.
