the DSRC-C mask is strictly for high-power applications. The DSRC-A mask is
identical to the mask defined in the widely used 802.11Wi-Fi standard, which is most
commonly used in-home wireless LANs and consumer hotspots. These 802.11 devices
are readily available for purchase and significantly reduce cost and time to market for
wireless deployments. Higher power units that are above 20 dBm of output power are
required for deploying mobile networks and need to employ the DSRC-C mask.
2. DCMA-82 4.9 GHz PSB Introduction
DCMA-82 is now certified to operate under Part 90, Subpart Y of the FCC
Rules to operate as a high power device in the 4.9 GHz PSB band with 10 and
20MHz channel bandwidths. DCMA-82 itself as module product and will be
bundled with server products. The 4.9GHz products will have separate ordering
codes and will be available only to customers who have applied and received
authorization by the FCC to use the public safety band. These products will be
marketed separately than our other wireless products. All other wireless products
shipped will not offer the possibility to use the 4.9GHz public safety band to the
customer and installer.

20 MHz bandwidth settings may operate at signaling rates up to 54 Mbps,
¾
10 MHz bandwidth settings may operate at signaling rates up to 54/2 (27) Mbps
Notes:
Professional Installation Guidelines
DCMA-82 was tested for compliance to the Federal Communication
Commission (FCC) rules part 15.247 and 4.9GHz complies with Part 90. Due to the
coexistence of non-licensed and licensed transmitter in the same module, the final
products which incorporate this module are subject to professional installation and the
installer has to make sure that the final installation will comply with the applicable
rule parts.
