In these rules, unless the context otherwise requires, —
(a) “Act” means the Indian Telegraph Act, 1885 (13 of 1885);
(b) “Authority” means the authority notified by the Central Government under sub-section (2) of section 4 of the Indian Telegraph Act, 1885 (13 of 1885);
(c) “access point” means a transceiver that operates either as a bridge in a peer-to-peer connection or as a connector between the wired and wireless segments of the network;
(d) “dynamic frequency selection” means a mechanism that dynamically detects signals from other systems and avoids co-channel operation with these systems, notably radar systems;
(e) “equivalent isotropic radiated power” or “e.i.r.p” means the total power that would have to be radiated by a hypothetical isotropic antenna to give the same signal strength as the actual source in the direction of the antennas strongest beam;
(f) “emission bandwidth” means the 26 dB bandwidth of the modulated signal measured relative to the maximum level of the modulated carrier;
(g) “maximum power spectral density” means the maximum power within the specified measurement bandwidth, within the device operating band; measurements in the 5 725-5 875 MHz band are made over a bandwidth of 500 kHz;
measurements in the 5 150-5 250 MHz, 5 250-5 350 MHz, and 5 470-5 725 MHz bands are made over a bandwidth of 1 MHz or 26 dB emission bandwidth of the device, whichever is less;
(h) “maximum conducted output power” means the sum of the transmit power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power level; if multiple modes of operation are possible (e.g., alternative modulation methods), the maximum conducted output power is the highest total transmit power occurring in any mode;
(i) “power spectral density” means the power spectral density is the total energy output per unit bandwidth from a pulse or sequence of pulses for which the transmit power is at its maximum level, divided by the total duration of the pulses and the total time does not include the time between pulses during which the transmit power is off or below its maximum level;
(j) “transmit power control” means a feature that enables a device to dynamically switch between several transmission power levels in the data transmission process;

(k) “device” means the intentional radiators operating in the frequency bands 5 150-5 250 MHz, 5 250-5 350 MHz, 5 470-5 725 MHz and 5 725-5 875 MHz that use wideband digital modulation techniques and provide a wide array of high data rate in mobile and fixed communications for individuals, businesses, and institutions;
(l) words and expressions used in these rules and not defined but defined in the “Act” and the Indian Wireless Telegraphy Act, 1933 (17 of 1933), shall have the same meanings respectively as assigned to them in those Acts.
