5. Modifying a Wireless Network
5.1 Infrastructure Mode and Ad Hoc Mode
You can set the Wireless Network Adapter to work in either Infrastructure mode or
Ad Hoc mode.
Infrastructure Mode
In infrastructure mode, devices communicate with each other by first going through
an Access Point (AP). Wireless devices can communicate with each other or can
communicate with a wired network. When one AP is connected to wired network
and a set of wireless stations, it is referred to as a BSS (Basic Service Set).
Ad Hoc Mode
Ad-hoc mode is also called “peer-to-peer mode” or “Independent Basic Service Set
(IBSS)”. In ad hoc mode, devices communicate directly with each other without
using an Access Point (AP).

Appendix A: FAQ about WLAN
1. Can I run an application from a remote computer over the wireless network?
This will depend on whether or not the application is designed to be used over a
network. Consult the application’s user guide to determine whether it supports
operation over a network.
2. Can I play computer games with other members of the wireless network?
Yes, as long as the game supports multiple players over a LAN (local area network).
Refer to the game’s user guide for more information.
3. What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique developed by
the military for use in reliable, secure, mission-critical communications systems. It is
designed to trade off bandwidth efficiency for reliability, integrity, and security. In
other words, more bandwidth is consumed than in the case of narrowband
transmission, but the trade-off produces a signal that is, in effect, louder and thus
easier to detect, provided that the receiver knows the parameters of the
spread-spectrum signal being broadcast. If a receiver is not tuned to the right
frequency, a spread-spectrum signal looks like background noise. There are two main
alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping
Spread Spectrum (FHSS).
4. What is DSSS? What is FHSS? And what are their differences?
Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes
frequency in a pattern that is known to both transmitter and receiver. Properly
synchronized, the net effect is to maintain a single logical channel. To an unintended
receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence
Spread-Spectrum (DSSS) generates a redundant bit pattern for each bit to be
transmitted. This bit pattern is called a chip (or chipping code). The longer the chip,
the greater the probability that the original data can be recovered. Even if one or more
bits in the chip are damaged during transmission, statistical techniques embedded in
the radio can recover the original data without the need for retransmission. To an
unintended receiver, DSSS appears as low power wideband noise and is rejected
(ignored) by most narrowband receivers.
5. Would the information be intercepted while transmitting on air?
WLAN features two-fold protection in security. On the hardware side, as with Direct
30
Sequence Spread Spectrum technology, it has the inherent security feature of
scrambling. On the software side, WLAN offers the encryption function (WEP) to
enhance security and access control.
6. What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or
128-bit shared key algorithm, as described in the IEEE 802.11 standard.
7. What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is
configured to communicate with a wired network through a wireless access point.
8. What is roaming?
Roaming is the ability of a portable computer user to communicate continuously
while moving freely throughout an area greater than that covered by a single access
point. Before using the roaming function, the workstation must make sure that it is the
same channel number with the access point of dedicated coverage area.
To achieve true seamless connectivity, the wireless LAN must incorporate a number
of different functions. Each node and access point, for example, must always
acknowledge receipt of each message. Each node must maintain contact with the
wireless network even when not actually transmitting data. Achieving these functions
simultaneously requires a dynamic RF networking technology that links access points
and nodes. In such a system, the user’s end node undertakes a search for the best
possible access to the system. First, it evaluates such factors as signal strength and
quality, as well as the message load currently being carried by each access point and
the distance of each access point to the wired backbone. Based on that information,
the node next selects the right access point and registers its address. Communications
between end node and host computer can then be transmitted up and down the
backbone. As the user moves on, the end node’s RF transmitter regularly checks the
system to determine whether it is in touch with the original access point or whether it
should seek a new one. When a node no longer receives acknowledgment from its
original access point, it undertakes a new search. Upon finding a new access point, it
then re-registers, and the communication process continues.

Appendix B: Wireless 4.9 GHz Band Statements
1. Background Information on the 4.9 GHz Public Safety
Band (PSB)
The Federal Communication Commission (FCC) has allocated 50 megahertz
(MHz) of spectrum in the 4940-4990 MHz band (4.9 GHz band) for fixed and mobile
wireless data communications, designating the band for use in support of public safety
(Public Safety Band, PSB). Specifically, the Commission adopted two emission
masks limiting interference potential for the band, one for low power and one for
high-power operations. These changes will allow public safety licensees to leverage
commercial off-the-shelf (COTS) technologies available for the U-NII and ITS
frequency bands. The FCC action allows for a nationwide focus on homeland
security, and will ensure that all state and federal agencies possess the required
communications resources to adequately protect the public.
This allocation will provide public safety users the additional spectrum required
to support broadband applications such as high-speed data transitions and video over
wireless, which in turn enhances local area networks for incident monitoring and
supervision. The spectrum can also be used to support the dispatch operations
communications as well as safety vehicle communications. Public safety agencies
will be able to implement on-scene wireless networks for streaming video, rapid
Internet and database access, and transfers of large files such as maps, building
layouts, medical files, and missing person images. It also allows these agencies to
establish temporary or permanent links to support surveillance operations. This
allocation gives every jurisdiction in the country access to spectrum for deployable,
interoperable, broadband communications.
40
The spirit behind the creation of the band was to allow the public safety
organizations access to inexpensive hardware already available for the ISM bands, but
in a section of the spectrum that is not available to the general public.
1.1. Key Facts of the 4.9 GHz PSB band
¾ The FCC allocates the 4.9 GHz band for fixed and mobile communication.
¾ The FCC designates the 4.9 GHz band for use solely in the support of public
safety encompassing the protection of life, health and property.
¾ Users must be a state or local government entity or non-government entity
authorized by a local or state public safety entity.
¾ Provide services that are not commercially available to the public.
¾ The FCC rules allow a maximum total power output of 33 dBm (2 W) per
channel and a maximum antenna gain of 9 dBi for a maximum EIRP of 42 dBm.
¾ Public safety agencies can apply for licenses to use the spectrum within their
areas of jurisdiction.
¾ The FCC rules permit broadband mobile operations, fixed hotspot use and
temporary fixed links.
¾ Fixed point-to-point operations are also permitted but this use requires a separate
license from the FCC for each station.
¾ The FCC rules prohibit use for services that are made commercially available to
the public.
¾ The new looser emissions mask is designed to allow users to utilize off the shelf
technology to significantly reduce cost and time.
1.2. Eligibility for 4.9 GHz PSB Use
All state and local government entities that provide public safety services, this
is defined as their primary focus being the protection for the safety of life, health, or
property; are eligible to apply for a 4.9-GHz license. The control of the licensing is
being managed at the state and local level to facilitate priority and availability of the
4.9 GHz band. Entities that do not meet these eligibility requirements, but that
provide services in support of public safety, such as private infrastructure
41
companies, can negotiate sharing agreements with license holders.
1.3. 4.9 GHz PSB Frequency Band Plan
The 4.9 GHz band ranges from 4940.5-4989.5 MHz and can be segregated out
using 1, 5, 10, 15, and 20 MHz of bandwidth.
1.4. 4.9 GHz PSB Licensing Requirements
A 4.9 GHz band license gives the licensee authority to operate on any
authorized channel in this band within the applicant's legal jurisdiction such as city,
county, or state. The 4.9 GHz band is shared by all licensees, who must coordinate
their usage of the band with other licensees within their areas of authority. The 4.9
GHz licenses are granted for a 10-year term.
The license gives authority to construct and operate:
¾ Any number of base stations anywhere within the area authorized by the license
¾ Base and mobile units, including portable and handheld units
A 4940-4990 MHz band license does not give the licensee authority to
operate permanent fixed point-to-point stations. Licensees choosing to operate
such fixed stations must license them individually on a site-by-site basis. Such
fixed operation will be authorized only on a secondary, non-interference basis to
base, mobile and temporary fixed operations.
1.5. 4.9 GHz PSB Peak Power Limits

1.6. 4.9 GHz PSB Emission Mask
The FCC has adopted two emission masks for use in the 4.9 GHz band. The
first being DSRC-A, is a mask strictly for low-power applications. The second being
42
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.
¾ 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.
