Bluetooth Advertising Proximity Range
Bluetooth advertising generally is a broadcast function. The average range of Bluetooth advertising in class 2 is 15 meters to 40 meters for most Bluetooth enabled mobile devices.
As with all wireless transmission, the range and accessibility to most Bluetooth advertising depends on the transmitter power class and the individual portage of the receiver equipment. However with advances in mobile devices technology, this distance for proper receiving is increasing to reach 250 meters or more in nowadays smart phones, tablet computers and other mobile devices.
The selectivity goes down with extension of range. Hence the transmission power raise as well as receiver sensitivity raise will reduce the contextual connection between actual location of receiver and contents of broadcast message.
There are several major types of Bluetooth advertising solutions. That are generally Bluetooth dongles as transmitter hardware in conjunction with mostly USB networked common server functions.
Embedded scheduling software serves transmission via dongles to enabled Bluetooth receivers. As Bluetooth reception modes require battery power, the distribution depends on the preparedness of the bearers of receiver units for receiving such transmission.

Famous quotes containing the words advertising, proximity and/or range:
“Life is beset by many annoyances, and those that stand out above all are the life- insurance and advertising agents.”
—Alice Foote MacDougall (1867–1945)
“The triumphs of peace have been in some proximity to war. Whilst the hand was still familiar with the sword-hilt, whilst the habits of the camp were still visible in the port and complexion of the gentleman, his intellectual power culminated; the compression and tension of these stern conditions is a training for the finest and softest arts, and can rarely be compensated in tranquil times, except by some analogous vigor drawn from occupations as hardy as war.”
—Ralph Waldo Emerson (1803–1882)
“Whereas children can learn from their interactions with their parents how to get along in one sort of social hierarchy—that of the family—it is from their interactions with peers that they can best learn how to survive among equals in a wide range of social situations.”
—Zick Rubin (20th century)
