Frequency Bands and Channels
The S1100 supports communications in the following frequency bands, in North America
and Europe:
„
2.4 GHz OFDM, also known as 802.11g
„
4.9 GHz OFDM, a public safety band available in North America only
„
5 GHz OFDM, also known as 802.11a
2.4 GHz Band
The 2.4 GHz band provides 11 channels in North America and 13 in Europe. In these two
regions, only channels 1, 6, and 11 are independent (that is, non-overlapping). All these
channels are for indoor or outdoor use. The center frequencies of the channels are:
4.9 GHz Band
The 4.9 GHz band is a licensed band for entities providing public safety services focused on
the protection of life, health, or property in North America. This band provides license
holders with an interference-free, secure channel for robust and secure broadband
technologies, including wireless video surveillance systems.
For more detailed information concerning the regulations governing licensing and use of
frequencies in the 4.9 GHz band, see Subpart Y of the FCC document, Memorandum
Opinion and Order and Third Report and Order at:
http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-03-99A1.pdf
The 4.9 GHz band has a width of 50 MHz (4940 to 4990 MHz). Since the standard channel
width is 20 MHz, only two independent channels can co-exist in the band. However, the
S1100 supports channel fragmentation, allowing narrower channels of 5 MHz and 10 MHz.
You can have up to four independent channels with a 10 MHz width, and up to 10 with a
5 MHz width. All these channels are for indoor or outdoor use. For more information about
channel fragmentation, see page 45.
