Design Team Mission

• The design team will determine the locations and
  topologies of the APs based on RF analysis, as
  well as geographic and predetermined constraints.
  In addition, the design team will research,
  develop and integrate captive portal interfaces
  and collect user data.

11
Design Team Main Tasks

• Hardware Familiarization/Initial Site Selection
• Establish Hardware Settings/Study sites
• Propagation Studies/Site Selection
• Establish Captive Portal Page

12

• Propagation/Location Selection Abhaya
• AP/WDS Research and Configuration Sandesh
• Captive Portal Vishanth

13
Document/Location Research

• To review the old documents.
• To determine the locations of Access points.
• To note the changes of the locations of APs from
  the previous document.

14
Procedure Review Old Documents

• The previous documents were reviewed.
• The details of the Locations of Access Points
  were noted.
• Only one AP on top of Hotel Utica.
• The channel on which the AP on Hotel Utica was
  channel 3

15
Proposed AP Specifications

• Three APs on top of Hotel Utica.
• Three different channels being used for the three
  APs.
• There would be 10 APs connected to three APs
• The APs are connected to the AP on top of Hotel
  Utica in WDS fashion with maximum of two
  Hop-Counts.

16
Proposed/Final APs Locations

• Varick Street
• Stanley Theatre
• Utica Zoo
• REC center
• Munson Williams
• State Building
• State Office Building
• Childrens Museum
• Marina
• SUNY IT Backhaul

Access Point Locations
19
Propagation and Location Selection

• Determining the line of site for all the proposed
  locations with respect to the antennas mounted on
  Hotel Utica
• Checking for the coverage of each of the proposed
  access points utilizing Radio Mobile.

20
Radio Mobile Software

• Radio Mobile a software tool used to predict the
  performance of a radio system.
• Freely Available at http//www.cplus.org/rmw/rme.

21
Specifications Radio Mobile Inputs

• Specifications considered as input to Radio
  Mobile to obtain results. 
• Specifications of each sector of the Antenna
  Mounted On Hotel Utica 
• Transmitter Power 29 dBm
• Receiver Power    79 dBm
• Minimum Frequency 2401 MHz
• Maximum Frequency 2498 MHz
• Height of Antenna      10m (assumed)
• City loss 5 (assumed)
• Cable loss 0.5 (assumed)
• Mode of Variability Broadcast
• Climate Maritime Temperate Over Sea
• Topology Master Slave Topology

22
Procedure - Radio Mobile Inputs

• Radio Mobile capable of importing maps from
  various sources, including elevation, building
  and terrain data
• For this project, Terraserver USA was used for
  this data

23
Procedure Radio Mobile Outputs

• The foot print or, rather, the strength of the
  signal being radiated
• Orientation, with respect to the antenna mounted
  on the Hotel Utica, we determine the line of
  sight between the two points
• Taking the results obtained from the line of
  sight, the below parameters are inferred

24
Procedure Radio Mobile Outputs continued

• Azimuth Angle
• Fresnel Zones 
• Power of the radiation at that zone

25
Procedure Radio Mobile Outputs

• The coverage of access points is considered and
  the exact location of the access point is
  determined with the help of a GPS in the
  suggested zone.
• The details obtained are also used to reduce the
  number of access points, to make the project cost
  effective and reduce the complexity involved in
  deploying the network.

26
Results Radio Mobile Outputs

• Individual sites/coverage
• Line of Site (LOS) information
• Overall Network Coverage

Captive Portal

• A captive portal is a Web page that the user of a
  public-access network is obliged to view and
  interact with before access is granted.
• Utica wireless provides free access to internet
  for two hours to each user everyday
• Every user has to register first to access the
  network

37
Login Page
38
Captive Portal

• When the user connects to the network a login web
  page is encountered
• Authentication of the user is done with the
  username and password
• After authentication is done a timer starts up to
  limit the internet access to two hours per day to
  each user

75
Installation Procedures

• Test the RWO-Plus-HPG and Antenna before taking
  them to the site.
• Connected the L Bracket the RWO-Plus-HPG
• Mount the Radio on the pole using the U clamp

(Diagram taken from the manual)
76
Installation Procedures

• Create a straight through cable to connect the
  RWO-Plus-HPG to the Power Over Ethernet Injector/
  Splitter.
• The Power Over Ethernet Injector/ Splitter. Is
  connected to a power source using the 48VDC power
  supply adapter.

77
Site Evaluation Checklist

• The laptop should be able to ping the
  RWO-Plus-HPG using the wireless LAN.
• The laptop should also be able to ping other
  access points successfully by connecting directly
  to the RWO-Plus-HPG access point using a CAT5,
  Ethernet cable
• Using the web interface, a site survey should be
  taken so that the RWO-Plus-HPG would search for
  other access points.
