Fellow Surveyors,


Can anyone outline the relative advantages/disadvantages of UHF and Spread Spectrum internal radios in GNSS receivers. I'd imagine issues like range, interference, battery life etc. would be most relevant.

Thanks!

  • Thanks so much for your response. I don't think I outlined myself as best as I could though. The distinction and comparison between external radios vs internal radios is appreciated. But my question is about internal radios specifically; I come across the option for internal UHF and internal Spread Spectrum, and was wondering what the distinguishing factors there were between each when in internal configurations.

    Hope this clarifies.

    Thanks again!

    Tim, in my opinion it makes for a more compact unit eliminating weight, mfg cost, and connection problems. As far as RANGE, pretty much consistence by the specs, but limited compared to the 35Watt external ad on, a $4,500 solution. The internal Spread Spectrum are really good radios and Spread Spectrum have been around a long time. Unless you do lots of boundary, internals will give you the distance you need to do most projects. POWER-the reason the units can be internal is the Energy Saver components that the battery powers have all been reduced through the years. They usually give you 2 batteries with each unit, with at least 4 to 5 hours with each. A RELIABLE, COMPACT, and PRODUCTIVE solution...although, if a radio goes down you pretty much send the unit in to the repair shop, where externals are a component, quicker to replace.

    The only other thought is, if your working in areas where you can get a internet signal. Also where there is a VRS available, equiping those units with a GSM module allow you to turn both into ROVERS, no Base needed. But even if you did want to use this option after the fact, there are other ways to turn both into Rovers through a bluetooth phone or add the Enfora SDcard into the slot of your Data Collector. 

    Hope this information helps you let me know if I can help.

How to use Forums
Our forums on Land Surveyors United are here to be used as much for finding help with problems in the field as the are for you to express your opinions on anything that has to do with land surveying in general. Feel free to share anything that is on your mind, as long as it isn't meant to damage another member's reputation. Please keep it clean and help insure that everyone has the opportunity to enjoy the benefits of being part of a community that grows together.

We are committed to allowing freedom of expression for all of our members, and that includes maintaining a safe space for people with opposing views to express themselves. We get posts from all over the country and even the globe, so needless to say, people come with different viewpoints on lad surveying practices and processes. We see this diversity and variety as a real strength-- dialogue and debate are an integral part of the educational process, as well as an important tool in exploring different sides of complex issues.

All Community Hubs inside the community have their own forum for asking specific questions to other surveyors, by location, equipment type, etc.
