Overview 
The ProST is an outdoor WiMAX-based customer premises equipment (CPE). The ProST, which 
uses Intel Corporation’s Pro/Wireless 5116 broadband interface, connects IP-enabled devices 
directly to WiMAX networks. Designed for the residential and small enterprise (SME) markets, the 
device supports high-speed broadband Internet through a Fast Ethernet connection.  
The ProST ensures high service availability at enhanced ranges, operating in both LOS and 
NLOS propagation environments. ProST uses the OFDM signaling format, providing non line-of-
sight (NLOS) performance. ProST utilizes QAM, QPSK, and BPSK modulation technologies by 
modulating transmitted signals and demodulating the received signals where the original digital 
message can be recovered. The use of adaptive modulation allows ProST to optimize throughput, 
yielding higher throughputs while also covering long distances.  
ProST models support IP services at speeds of up to 37 Mbit/s over-the-air gross rates over 
channel bandwidths of up to 10 MHz in both uplink and downlink. ProST is available in numerous 
ETSI frequency bands, operating in FDD and TDD modes in numerous channels, see:

ProST is also available in a multi-mode model (ProST-2) based on the Intel ® Rosedale chipset 
which supports both TDD and FDD. 
 
Note:
 ProST-2 is presently available for frequencies, 3.4–3.6 and 3.6–3.8 
only
 
ProST can be deployed with a built-in, integral antenna or alternatively, with an external antenna 
to provide better radio coverage. Requiring professional installation, the ProST is installed 
outdoors on a pole or wall, enabling optimal positioning for best reception with the BS. Outdoor 
mounting of the ProST is made possible due to ProST's built-in lightning surge protection feature 
(complying with Surge Immunity standard EN 61000-4-5).   
ProST is powered through the SDA-1 Type II (referred henceforth as SDA-1) adapter which 
interfaces with the subscriber's LAN. ProST connects to the SDA-1's 100BaseT interface port by 
a standard 100-meter CAT-5 cable. The SDA-1 also provides the ProST with 10 to 52 VDC power 
supply. However, as an alternative to these adapters, Airspan offers three optional integrated LAN 
switches: 
•  SDA-4S Type II: A standard integrated LAN switch, providing four 10/100BaseT 
interfaces with the subscriber’s computers. This model is ideal for SOHO 
implementation. 
•  SDA-4S/VL Type II: Provides VLANs between ports and the ProST, ensuring privacy 
between LAN users of the different ports. For example, all users connected to Port 1 
do not "see" users connected to Port 2. This model is ideal for multi-tenant (VLAN 
security) implementation. 
•  SDA-4S/DC Type II: integrated LAN switch, providing power and  four 10/100BaseT 
interfaces and especially designed for implementation where available power supply 
is DC (10 to 52 VDC), e.g. from a solar panel. This model provides regulated –48 
VDC power to the BSR. 
All SDA types work in VLAN Pass-through mode. Tagged and Untagged packets are forwarded 
transparently by the SDA. The SDA has no VLAN ID configuration per port. 
ProST can be managed by Airspan's Web-based management system using standard Web 
browsers or alternatively, by an SNMP-based network management system (Netspan) using 
standard and proprietary MIBs. In addition, external third-party management systems such as HP 
OpenView can also manage the ProST using these MIBs.
