Yoshihisa Okumura
Dr. Yoshihisa Okumura (born 1926, in Isikawa Prefecture) is a Japanese engineer, known for development of cellular telephone networks. His radio survey of signal strength as a function of distance as measured in drive tests in automobiles was critical to the system planning of mobile radio telephone systems. Professional career Okumura studied electrical engineering at Kanazawa Technical College (金沢工業専門学校 Kanazawa kōgyō sermon gakkō, former the faculty of engineering of Kanazawa University) from 1944 to 1947. Dr. Okumura began his professional career in 1950 with Nippon Telegraph and Telephone Public Corporation (NTT, now privatised), where he collected radio propagation data in the 150 to 1920 MHz bands. These bands were later identified as appropriate for mobile phone systems (in no small part, because of the data collected by Okumura). Okumura's careful study in various topographical environments in metropolitan, suburban, rural and even mountaino ...

People From Ishikawa Prefecture
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...
