4. Antenna requirement 4.1 Regulation An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of Part 15C. The manufacturer may design the unit so that the user can replace a broken antenna, but the use of a standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current devices or to devices operated under the provisions of Sections 15.211, 15.213, 15.217, 15.219, or 15.221.

The transmitter can be set to operate on any one of 256 frequency channels in the 902-928MHz band. The frequencies are divided into four groups of 64 frequencies; each group using every fourth available frequency. 63 out of 64 frequencies in a group are then used equally by the spread spectrum transmitter in a pseudo random sequence. 63 different sequences are available for use in each frequency group.

12.3 Test Procedures For tabletop equipment, the EUT is placed on a 1 meter by 1.5 meters wide and 0.8 meter high nonconductive table that sits on a flush mounted metal turntable. Floor standing equipment is placed directly on the flush mounted metal turntable. The EUT is connected to its associated peripherals with any excess I/O cabling bundled to approximately 1 meter. Preview tests are performed to determine the “worst case” mode of operation. With the EUT operating in “worst case” mode, emissions from the unit are maximized by adjusting the polarization and height of the receive antenna and rotating the EUT on the turntable. Manipulating the system cables also maximizes EUT emissions. Radiated Emissions Test Characteristics Frequency range 30 MHz – 10,000 MHz 15.205 RESTRICTED BANDS ONLY Test distance 3m Test instrumentation resolution bandwidth 120 kHz (30 MHz - 1000 MHz) 1 MHz (1000 MHz - 10000 MHz) Receive antenna scan height 1m-4m Receive antenna polarization Vertical/Horizontal Calculation of average correction factor = 20 * log (20 mSec/100 mSec) = 20 * log .2 = -14 dB 20 milliseconds is the worst case on time for any 100 milliseconds time frame.

13. Continuous Data and Short Transmissions 13.1 Regulation 15.247(g) Frequency hopping spread spectrum systems are not required to employ all available hopping channels during each transmission. However, the system, consisting of both the transmitter and the receiver, must be designed to comply with all of the regulations in this section should the transmitter be presented with a continuous data (or information) stream. In addition, a system employing short transmission bursts must comply with the definition of a frequency hopping system and must distribute its transmissions over the minimum number of hopping channels specified in this section. 13.2 Test Results When required to send continuous data, all frequencies of a sequence (63) are used one before any re-use of frequencies occurs. When presented with a short burst, any one frequency is not re- used until all frequencies (63) of sequence have been used. The sequence is not truncated and re- started.

14. Coordination of Frequency Hopping 14.1 Regulation 15.247(h) The incorporation of intelligence within a frequency hopping spread spectrum system that permits the system to recognize other users within the spectrum band so that it individually and independently chooses and adapts its hopsets to avoid hopping on occupied channels is permitted. The coordination of frequency hopping systems in any other manner for the express purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple transmitters is not permitted. 14.2 Result This system does not incorporate intelligence to avoid interfering carriers. It progresses linearly through the hopping sequence. DATE OF ISSUANCE: 22 JANUARY 1999 REPORT NUMBER: 980335 FCC ID: IA9T100-900 PAGE 21 OF 22
