… all of its old CDMA gear replaced with new software-defined radio (SDR) capable of hosting any network technology.
This is another gentle reminder that SDR is for everyone, not only the military and first responders (although, in reviewing my recent posts, I can see why one might draw the opposite conclusion). Here’s the blurb from the Sprint PR material:
With Network Vision, Sprint will make substantial changes to the cell sites that power its wireless network. The top image shows Sprint’s existing base stations, which require single, refrigerator-sized cabinets for each technology. Large black coaxial cables must run from each cabinet to the top of the cell tower, which has an inherent loss of signal. The Network Vision multi-mode base station will require less space. Other advantages will include the ability for Sprint to use spectrum bands on multiple technologies, replacing coaxial cables with fiber that is not affected by signal loss and improved remote radio heads that replace existing less efficient radios.
The implementation of multi-mode technology throughout the Sprint network will:
- Enhance service
- Create network flexibility
- Reduce operating costs
- Improve environmental sustainability
Those sound like textbook SDR benefits to me!
… and, thanks to SDR …
Also, it seems that Sprint may finally be making the move to shed the archaic iDEN network that it picked up when it acquired Nextel. The fact that they highlighted “No immediate plans to force migrate iDEN customers…” in their published “Plan for Push-to-Talk” (PDF) speaks volumes.
