The Cisco 1801W and 1803W are fixed integrated services routers that provide high-speed DSL
broadband access through asymmetric DSL (ADSL) over basic telephone service (Cisco 1801W)
or symmetrical high-data-rate DSL (Cisco 1803W) with integrated ISDN S/T Basic Rate Interface
(BRI) backup. The Cisco 1811W provides high-speed broadband or Ethernet access through two
10/100BASE-T Fast Ethernet WAN ports and integrated WAN backup through a V.92 analog
modem. These routers also provide integrated dual-band 802.11a/g wireless access point
capability for various regulatory domains, including the Americas.
The Cisco 802.11g/a High-Speed WAN Interface Card provides integrated access point and
bridging functions in the Cisco 1800 (modular), Cisco 2800, and Cisco 3800 Integrated Services
Routers.
Release of New Cisco 1801W, 1803W, 1811W, and HWIC-AP Models Supporting
Integrated 5-Ghz 802.11 Access Points for North America
Because of changes in the FCC compliance requirements for the 5-GHz UNII-2 band for North
America, select models of the Cisco 1801W, 1803W, and 1811W wireless routers are being
transitioned to new models that will meet the new FCC requirements. Meeting these new FCC
requirements applies only to new product shipments; customers with existing equipment are not
required to meet these new specifications.
For new orders, Cisco part numbers 1803W-AG-B and 1811W-AG-B) replace the existing Cisco
part numbers 1803W-AG-A and 1811W-AG-A starting with Cisco IOS Software Release
12.4(11)XW1. The Cisco part number 1801W-AG-B is a new product that is available for the first
time for the Americas. The Cisco part number HWIC-AP-AG-B replaces the existing Cisco part
number HWIC-AP-AG-A starting with Cisco IOS Software Release 12.4(11)XW1.
Cisco announced the end-of-sale and end-of life dates for select models of the Cisco 1800s
(1803W-AG-A/K9, 1811W-AG-A/K9) and HWIC-AP-AG-A. The last day to order these models was
June 29, 2007. The new models are fully compliant with FCC regulations for operations in the 5-
GHz UNII-2 band. Migration to the new models is required to meet FCC wireless specifications that
became effective in July 2007.
