Interesting Information On Background & Origin Of Mobile Phone
Before the advent of mobile phone, radio telephony technology was in use. The first-class passenger trains, between Berlin and Hamburg, made great use of the technology in 1926. Radio telephone was also used in passenger airplanes and for the purpose of air traffic security. German tanks, during the Second World War, made use of radio telephony at a large scale. At that time, people were especially trained to use the equipment.
Two-way radios served as the predecessor of the present day cellular phones. Before the advent of handheld cell phones, two-ways radios, known as mobile rigs, were installed in vehicles like taxicabs, ambulances and police cruisers, that too permanently. Since mobile radios were not connected to the telephone network, people could not dial them from their home phones. However, this technology gained immense popularity among mobile radio users.
Later version of mobile radio phones came to be known as "bag phones", which came with integrated cigarette lighter plug. Installed in a vehicle permanently, they were used either as mobiles or as portable two-way radios. Later on, in the beginning of 1940s, Motorola Company came with a new development in the field of mobile phones - a backpacked two-way radio, called "Walkie Talkie". It was a large and bulky handheld two-way radio, as big as a man's forearm. Known as battery operated "Handie-Talkie", it found a use in the US military.
Please note the last line, as you seem to often forget to read. As I said before, you ought to do a little research before you accuse others of being "wrong", even "categorically" so, or "not GETTING it". Since you were inaccurate about walkie talkies being predecessors of the later mobile or cell phone I think that being the case, all the rest of your posting can be called into question. You sound like a person who is nervously anxious about being proven incorrect, especially by one who actually researches and tries to back up what is being claimed. There is an old saying that goes, "if you can't dazzle them with brilliance, baffle them with bullshit"--in your case, you are very short on the former and overlong on the latter. You seem to have alot of growing up to do, even at age 50 as you claim.
