PRELIMINARY PRELIMINARY Safety Precautions RF Energy Radiation Warning The radio equipment described in this guide uses radio frequency transmitters. Although the power level is low, the concentrated energy from a directional antenna may pose a health hazard operated incorrectly. All devices must be installed by qualified installation / deployment personnel, and a minimum of 1.5 meters of separation must exist between the device and persons, when the device is operating. The device installers and operators should be aware of the transmitter operating conditions specified in the Wireless Bypass DL-5800 installation manual and other associated user documentation, as well as the antenna co-location requirements of Part 1.1307 (b) (3), of FCC rules, pertaining to RF exposure. Protection from Lightning Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and television lead-in cables must have adequate surge protection at or near the point of entry to the building. The code specifies that any shielded cable from an external antenna must have the shield directly connected to a 10 AWG wire that connects to the building ground electrode. Regulatory Notices: Canada: Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesirable operation of the device. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropic radiated power (EIRP) is not more than that required for successful communication. United States: CAUTION: Modifications to this device not expressly approved by Wireless Bypass may cause the device to exceed regulatory standards and therefore VOID the user’s authority to operate the device. This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause PRELIMINARY PRELIMINARY interference, and (2) this device must accept any interference received, including interference that may cause undesirable operation. PRELIMINARY PRELIMINARY System Description Wireless Bypass Cable Access Radio Systems are high performance, wireless, microwave communication links that provide an efficient solution for Cable Modem data transmission requirements. These systems operate in the unlicensed 5.8 GHz U-NII band between 5.725 & 5.825 GHz. The Wireless Bypass DL-5800 Series U-NII Cable Access Radio enables cable operators to expand their cable service market by delivering high-speed Internet service to customers previously inaccessible with the installed HFC network. The Wireless Bypass system described in this manual consists of a HUB radio frequency unit, and a CPE (Customer Premise Equipment) radio frequency unit. Several different antenna configurations may be described for point-to-point, or point-to-multipoint operation. In multipoint configurations, many CPE’s may be used with one HUB. The HUB connects to the installed HFC network using standard cable drop techniques. The HUB contains all the signal processing necessary to transmit the downstream IP data into the coverage area and insert the upstream data bursts into the HFC network. The CPE is a small radio transceiver installed at the customer site that provides the downstream data and a return connection for the customer’s cable modems to the HFC network. The Antenna system used will be determined by the desired coverage area and network topology. Two basic Antenna systems may be used with the DL-5800: Point-to-Point, and Point-to-Multipoint. DL-5800 distance capability will range from about 2 miles in a Point-to- Multipoint implementation, and up to 20 miles for Point-to-Point. Basic main lobe antenna patterns are show below. ***************INSERT ANTENNA PATTERNS HERE*************** Equipment Design Features Wireless Bypass's radio systems provide patent pending advanced designs, incorporating a high level of circuit integration to achieve lower power consumption per terminal, and higher reliability for longer MTBF. Microprocessor-based intelligent monitoring of vital performance functions provides extensive diagnostics that are summarized to provide a single point red LED indicator, which will illuminate in the event of a malfunction. PRELIMINARY PRELIMINARY The highly integrated design of the Wireless Bypass DL-5800 series radio systems provide the user with a cost-efficient radio that is eas…

Wireless Bypass wireless solutions for CMTS and CATV distribution 12/21/2001 Transmitter Mute Switch & Transmitter Frequency Stability To Whom It May Concern: Wireless Bypass has built a transmitter mute function into the U-NII model PPS- DL-5801C24. These mute functions can be traced using the supplied documentation. Specifically, the transmitter mute will take effect from 90% to 10% in less than 1 millisecond in the event of a PLL out of lock, and less than 1 microsecond in the absence of data. Frequency stability of the PPS-DL-5801C24 is controlled by one upconversion at 5.700 GHz. Overall stability over temperature is +/- 1.0 PPM & over time +/- 1.0 PPM yielding a total of +/- 11,400 hz over time and temp. The attached crystal specification is applicable to all cases.

FCC Part 15 certification Questions from Roland Gubisch @ ITS Relationship between switch programming and RF power output The RF power switch settings are selected such that the maximum peak power emissions with the selected antenna are not exceeded. The switches define a 6-bit control word that sets the output power. Example: a single channel (6 MHz) hub system has a maximum peak power of 24.78 dBm into a 6 dBi antenna. Using a 15 dBi gain antenna requires a reduction in output power of 9 dB or a maximum output power of 15.78 dBm into the antenna. A control word of 110001 (49 decimal) is selected giving an output power of 15.4 dBm into the 15 dBi antenna. All switch settings for the various antennas are calculated in the same fashion. Point-to-multipoint systems use the maximum antenna gain of 6 dBi and point-to- point systems 23 dBi for the maximum antenna gain Output power vs. Control Word -40 -30 -20 -10 0 10 20 30 0 102030405060 Control Word Output Power (dBm ) Peak Power dBm

For transmitters operating in the 5725 – 5825 MHz frequency band the exposure limits for uncontrolled and controlled exposures are 5 mW/cm 2 and 1 mW/c m 2 respectively. Wireless Bypass offers two configurations of UNII band radio systems, point-to-multipoint (P/MP) and point-to-point (P/P). Each configuration of radio system contains a ‘downstream unit’ designated with an ‘H’ e.g. DL5800H, and an ‘upstream unit’ designated with a ‘C’. The ‘downstream unit’, DL5800H, has a 26 dB transmitter bandwidth of approximately 6 MHz and the ‘upstream unit’, DL5800C, has a 26 dB transmitter bandwidth of approximately 3.2 MHz. The following table gives give the distance from the antenna that the power density is 1 mW/cm 2 and the power density at a distance of 1.5 meters from the antenna. 1.5 meters is required in the Users Manual for uncontrolled distance.
