Nothing about voice calls is secure with a small number of exceptions.

Encryption for GSM was broken about 20 years ago and never fixed. Same thing happened to CDMA. With $25 worth of equipment, one can listen to any GSM call if one is in range. With CDMA, it takes about $35 worth of equipment.

Scarier is the fact that consumer/business wireless calls are governed by protocols that don't even try to authenticate a cell tower. That's why stingrays work and work well.

Lastly, the Snowden docs clearly show that cell carriers funnel all calls to the NSA. Their reasoning is that there is no need for a warrant because of the third party doctrine (see Smith v Maryland).

I was invited over here by @G-Dog stating I might enjoy the company here and the subject matter. He recommended I relate my recent experience during a hospital stay for 1 week while receiving a Bone Marrow transplant. As a back story to explain me a little better I am a retired Master Chief Hospital Corpsman and a retired Civilian R.N. I speak medical fluently. I am not a big fan of the so called "Medical Experts" who use medicalese to work their way out of uncomfortable situations. So I like to interpret for those who do not understand the language. As an example "The Prognosis is bleak" he/she is going to die. "I will have to consult with my peers on that" I don't have a clue. And the big one "The results are not in" I am even more clueless than my partner here. I am hated by the physicians, loved by the nurses, confuse the lawyers, and brought goodies by the ancillary staff. This time during Grand Rounds I would ask the difficult hard questions in their language and while they were mulling it over and grumbling, leave and go next door which was pediatrics for a few hands of Hold Em. Those Kidz are really good. A 3rd year medical student caught on to me and he was the only member of the Medical Experts who saw me regularly my last 3 days of my stay. Except the Hospital Administrator did come to see me to beg me to apologize to the medical staff for being an unruly patient 3 times. And I was banned from Pediatrics. So I did as the administrator requested and apologized to the medical staff by presenting the 3rd year medical student with a highly modified Sonic Blue Fender Mustang PJ for at least having a sense of humor and a great bedside manner. Others should try to take the hint.
Well do I qualify for being a Grumpy Old Fart- Stay Outta My Room!-?
Thank you for your time.

I'm shocked and saddened at the news of the passing of this fine man. He just joined the GOFs this last January. Bob, you will be sorely missed by all those you've served, and touched by your service, throughout your life. Thank you for your service, your enthusiasm and your dedication to the ideals you so exemplified. :(

In memoriam, Bobhmcs.

There are multiple technologies involved that will help on this front. The technology angle we are working is trading gain for bandwidth in the tuning approach/techniques and simultaneously improving the gain while also greatly reducing the size of the antenna. Dr. Jim Breakall (after you google him, yes it's that James Breakall) is our company's lead engineer on this advanced R&D effort.

Nothing is secure. Even your internet journey goes onto your permanent record, stored on a drive hidden deep in a server farm in the desert.

Growing up, the grandparents of pretty much every kid on the street (aka people from the old country) spoke some other language when they didn't want the grandkids to understand what they were saying. As a fallback there was always pig latin.
