OVERVIEW / DESCRIPTION

The Clearwire



Wireless Access Server is a multiple access, wireless, metropolitan area network device that

enables ISP’s to provide their subscribers direct local Internet access. Figure 1-1 shows a typical Clearwire



network. Each Clearwire



subscriber site has a radio link to the ISP, either direct or through a base station.

Customer Premise Equipment (CPE) at each subscriber site includes an antenna with co-located Outdoor Unit

(ODU), and an Indoor Unit (IDU).

EQUIPMENT SUPPLIED: Clearwire CPE hardware for subscriber sites includes the IDU, power supply, ODU/ antenna (one of two types), and connecting cables. • Indoor Unit (IDU). The IDU is a computation capable radio. Its processor, a high speed communications engine, is capable of running standard TCP/IP and Ethernet protocol stacks as well as processing its node’s role in the proprietary Clearwire air protocol. Processing includes precision timing, error control, and radio configuration/control.

• ASY_Power 5V Power Supply. The power supply (see Figure 1-4) uses 95 to 250 Vac, 47 to 63 Hz power to provide +5V and ±12V DC power to the IDU.

• The ODU is included as part of the antenna assembly (see Figure 1-5) and contains the receiver front end and the final stage of transmit power amplification. Power, signal and control all flow through a single thin coax cable to allow remote ODU location without a separate power source. Connector J1 is used for connection to the IDU by coax cable. Connector J2 is permanently attached to the antenna port by coax cable.
