The SNYPER-LTE Graphyte is a high performance, multi-language

network signal analyser and cellular signal logger, dedicated to surveying

and logging cell networks. The unit can be left to conduct sequential surveys in a fixed location and automatically save them. Four types of survey can be performed: a “FULL” survey (4G, 3G and 2G), 4G/LTE only, 3G/UMTS only & 2G/GSM only.


The SNYPER-LTE Graphyte can save multiple surveys each with different logging options. All survey results can be downloaded to a PC and displayed in a HTML graphical format to clearly show the logged detail over the survey session. This can identify unreliable base-stations & intermittent cellular service which is not possible with spot surveys. The full breakdown for the HTML summary graphs are displayed in corresponding CSV files.


The SNYPER-LTE Graphyte also incorporates Siretta’s leading liveSCAN feature, which allows you to select a base-station signal immediately after a survey, conduct a liveSCAN logging session which can later be analysed in a CSV logged recording.





  • Enhanced cellular surveying & sequential logging of new and existing installations on 4G/3G/2G networks
  • User selectable logging options to determine most reliable mobile operator
  • Evaluate MNO’s performance over time
  • Determine “hotspots” & assist with antenna alignment with liveSCAN
  • Results are reported in CSV & graphical HTML format
  • Save over 100 logged surveys with multiple liveSCAN log

Comment List
  • I have just returned from an extended vacation trip. Those friends still employed pounding salt in the corporate mines have told me the word vacation must be struck from my lexicon. It seems retirement is a permanent vacation to those still employed in the quarries, so there is no further need to use the word vacation.


    I received the unit from the shipper without physical damage. Below are the details from the tag on the handheld unit:


    Graphyte (USA)

    S/N 358148061224452

    SAP 60740

    Batch 43385


    I followed the enclosed instructions sheet. I am unable to complete step one. The unit powers up and then immediately shuts down.


    I am going to assume the immediate shutdown is the result of a power issue. The unit has been without power for a period and the batteries may be in need of a charge. My plan is to try and keep my fingers off the unit for a few hours and then try the sequence again. I just had another thought, there is not antenna connected. Maybe it needs an antenna on power up? This is a good time to go look for more documentation.


    I found no checklist to inventory the case components. All the holes in the foam case appeared to be filled so let's make another assumption all parts are here.


    With all the little bits and bobs floating in the case, I'm confident at some point in time I won't return a component to the case. My experience suggests, it never hurts to have a Inventory card in the box to confirm the unit is complete. Especially if the test equipment is available to a team. How many of us have had the experience of borrowing the overhead projector loaner to do a presentation to discover the power cord is missing?


    I will at some point in this project start blogging. I wanted to let the RoadTest support team know the unit has been received. I remind them, I will be in travel status once again and will shelf the RoadTest until the end of August. If you don't hear back from me on the power up issue, then assume I have a working unit.


    Again, thank you to the selection committee for the opportunity to participate in this initiative.



  • I assume it is acceptable to post a "Like" for the message that indicates you have been selected as the successful candidate for a RoadTest review.


    I'd like to thank the Academy. I will never get the chance to say that. I would like to congratulate all the individuals who applied for this RoadTest.  I trust my contribution will uphold the high standard our group has come to expect for RoadTest reviews.


    I have started working on the project while I wait to received the unit. I have contacted some former colleagues in the cell phone industry to participate. In return for their knowledge and contribution they will receive free beer. I have extensive back ground in RF but little experience in cell phone communication. Hopefully before the boys are drunk, I can get some testing done.


    The forum can expect the review posting sometime around the middle of September.  I threw my name into the hat, to participate in a Atlantic Salmon Snorkeling survey norkel-surveys-and-living-rivers  before the contest and was accepted. The late review date was acceptable to the selection committee.


    Fitting into my wet suit, I remind myself of a female I once saw on a public transit bus. She was four axe handles wide with a bright fluorescent orange tank top. She succeeded in covering all the contents south of her torso, with a pair of Lu Lu Lemon tights. The pressure on the seams of my wet suit might be reaching the kinetic energy applied to the threads holding those Lu Lu's together. It was an amazing example of engineering, the wet suit that is.



  • Congratulations to the roadtester!  Hopefully these will be interesting and enlightening reviews about a field that I have little knowledge about.

  • Congratulations to the road testers - this could be interesting - I don't know much about cell phone infrastructure.

  • The following applicants have been selected as official roadtesters:


  • Note: I have two versions of this unit: one version for North America and another version for Europe.

  • This instrument provides quite a bit of useful data if the network/provider is covered.  From the description this unit is only for EU/Europe so I won't apply although I'd love to try something like this in the US.

  • It turns out that Malaysia has majority of the bands of the EU unit image excluding B20

    GSM : 900 , 1800 -> B8, B3

    UMTS: B1, B8

    LTE: B3, B7


    major operators

    Digi:        B3/B8/B7

    Maxis    : B3/B7

    Celcom : B3/B7

    u-mobile -> B3/B7

    yes 4G -> voLTE


    I have never done a professional measurement of the cellular except using those free phone app (and this does spot measurement rather than the logging capability of the SNYPER-LTE Graphyte)  but recently did some experiment with RF propagation simulation, due to work . Anyhow, for sharing purpose

    here the simulation of cellular tower (one of them has its real counterpart at actual location on hilltop while another is a hypothetical). many countries are chasing the 5G now and i am myself trying to learn up some basics image


    Line of Sight (LOS)


    actual aerial map of cellular tower simulation. there is an actual cellular tower on the hill top


  • Telstra has LTE allocations in 2100MHz (B1), 1800MHz (B3), 2600MHz (B7), 900MHz (B8, very few sites), 700MHz (B28) all in FDD.

    Optus LTE allocations are quite similar - 2100MHz (B1 Tasmania), 1800MHz (B3), 2600MHz (B7), 700MHz (B28) in FDD and 2300MHz (B40) in TDD.
    Vodafone LTE is a bit odd compared to the rest - 2100MHz (B1), 1800MHz (B3), 850MHz (B5) in FDD.

    As for 3G/UMTS, we primarily use either 850MHz (B5, Telstra) or 900MHz (B8, Optus/Vodafone).

    Of all the 4G/LTE bands, the EU version will miss out on B5 (Vodafone), B28 (Optus, Telstra) and B40 (Optus). It will however capture all carriers on B1, B3, B7 and B8 which is not a bad effort, but perhaps if you have an "all band" phone with root access and software, you might be able to do better. The NA version will capture just Vodafone in B5, which is pretty worthless. On 3G/UMTS, the unit misses out on Telstra entirely, but can capture Optus and Vodafone. The NA version has no 3G/UMTS capability at all, missing all of them. As for 2G/GSM, all our services were terminated (with the exception of Christmas Island which is B8), thus that cannot (easily, legally) be tested either way but historically we would have been B8 and covered by the EU version as well.


    From my perspective, Australia would make a good test environment as we have something operating on most of the bands the unit supports and at least in 4G/LTE, most of the bands for every carrier are supported, especially the earlier and perhaps "more important" bands as a broader number of devices (especially imported ones) support these.


    I suspect those in other countries might not have as many bands in operation - just looking about a sampling of EU countries on FrequencyCheck:

    • UK uses B1, B3, B7, B20 for 4G/LTE and B1/B8 for 3G/UMTS
    • Germany and Austria uses B3, B7, B20 for 4G/LTE and B1 for 3G/UMTS
    • Belgium uses B3, B20 for 4G/LTE and B1/B8 for 3G/UMTS
    • Switzerland, Finland and Denmark uses B3, B7, B20 for 4G/LTE and B1/B8 for 3G/UMTS
    • Spain uses B3, B7 for 4G/LTE and B1/B8 for 3G/UMTS
    • Sweden uses B3, B7, B8, B20, B38 for 4G/LTE and B1/B8 for 3G/UMTS


    I have not yet found a candidate country which might exercise all bands on the EU model, although it might exist. But we come pretty close to being one of the best test environments, with the UK perhaps being better. As much as we might want a perfect kit, in reality there is no "perfect" kit, as often it will be down to what you can afford and using each piece of kit for what it is good at (or perhaps working around its limitations, or using it in conjunction with other gear).

  • I checked the datasheet and found that it will only test a couple of networks, mostly Optus and some of Vodafone.


    I was considering this but unfortunately, it would not be worth it, there are too many holes in the frequency allocations in Australia Network to provide a viable roadtest IMHO. The value in a professional capacity in my case couldn't be justified.


    Shame really would have been a nice piece of kit.
