4 2 Introduction Historically, Spread Spectrum Technology began life predominantly as a proprietary technology with limited functionality. The data speed over the radio interface was also low (2Mbps and below) and hence the clients were limited to a small selection of character based devices communicating at low throughput speeds via a TELNET connection to a host. Restrictions in the transmitted radio power also reduced devices to the use of a single low gain omni-directional antenna. The scope of a Site Survey was hence relatively small. Wireless Technology is currently expanding at a terrific rate with the introduction of the IEEE standard. Advances have also been made in other areas. Currently g devices are able to offer speeds of up to 54Mbps over the radio thus increasing the type and quantity of available clients exponentially. Coupled with this, the transmitted power of the device has reduced such that a broad selection of antennas can now be adopted. Finally, products have been enhanced to enable Site Surveys to be conducted in almost any environment (Cold Stores, Intrinsically Safe Zoned areas, offices, shipyards, airports etc). DW WiFi has recognised the requirement to tailor our Site Survey Process to cater for these new advances. Senior engineers are employed with years of experience using the various radio technologies available. To assist us in providing a survey that meets your requirements we ask that you complete this questionnaire. Version 1.15 Page 4

8 6 Survey Requirements 6.1 Access Point Selection Please note that all CISCO access points support the following radio standard and supports both b and g clients. 2.4 GHz IEEE g Direct Sequence Spread Spectrum Radio Please be aware that in a mixed cell environment (i.e. both b and g clients operating in the same coverage cell) the performance of the g clients will potentially be restricted to b speeds. Please select the required access point from the following list by placing a tick in the appropriate box. Please leave this section blank if you are undecided and require DW WiFi to advice you of the most appropriate choice on the day of the survey. Access Point Type Tick Box as required Cisco model 1231 Cisco model 1242 Version 1.15 Page 8

9 6.2 Proposed Client Devices It is important that DW WiFi are made aware of any clients that have been proposed for the wireless project. Please place a tick against any of the devices that have been proposed for your wireless project and indicate the proposed quantity of each. Proposed Client Device Features Quantity (if known) Tick Box as required CK3 IEEE b/g radio CK31 IEEE b/g radio CV30 IEEE b/g radio Version 1.15 Page 9

10 6.3 Type of Connection It is important that DW WiFi is made aware of any clients that have been proposed for the wireless project. The type and functionality of the client devices will often dictate the minimum link speed required from the wireless LAN. For example a low link speed (1Mbps) is sufficient if the wireless LAN supports ONLY client devices running terminal emulation. If the wireless LAN is required to also support b/g PC clients requiring high bandwidth then a much higher link speed is required. Please tick the appropriate options for your wireless project. Please tick Not Known if the devices have yet to be decided. Minimum Recommended Link Connection Type Speed (across radio interface) 5250 Emulation (AS400) 2Mbps and above b/g PC Clients 2-54 Mbps (depends on usage) Not Known Tick Box as required If the connection type proposed for your wireless project is not in the list please specify below with a description. Connection Type Description Version 1.15 Page 10

11 6.4 Minimum Link Speed It is possible to select the required minimum link speed at which your radio clients will connect to the wireless LAN. Please be aware that it may not be possible to always achieve the maximum speed of 54Mbps. There are many environmental factors that affect the link speed. The survey engineer will advise you of any issues encountered on the day of the survey and the likelihood of this affecting the link speed. Please select the required link speed. Please note that this is the minimum link speed available in the areas of coverage. As the radio signal to a client device improves (typically with proximity to an access point) the link speed is likely to increase above the minimum. Please take into account the type of devices selected for your project (previous section) when making your decision. Please tick the appropriate options for your wireless project. Please tick Not Known if the required minimum link speed is yet to be decided. Minimum Link Speed Notes Suitable for terminal emulation 2 Mbps clients 11 Mbps b PC Clients 54 Mbps g PC Clients Other (please specify) Tick Box as required It is possible to provide higher link speeds in designated areas of the site (eg 2Mbps and above link speed in warehouse to support terminal emulation clients and 54Mbps link speed in open plan office areas). If this is the case please identify your requirements below. Please be aware that the link speed is dependent on a number of environmental factors and hence some of the higher link speeds may not be achievable.

12 7 Site Conditions 7.1 Ethernet Network Each access point requires connectivity to an Ethernet network and as such Ethernet cabling (min CAT5) needs to be routed to all access point locations nominated as part of the survey process. Please answer the following questions specific to your wired network. Please note that DW WiFi does not offer Ethernet cabling as a service. It is our experience that customers often either use in-house resources to install Ethernet cabling or more commonly have a preferred cabling contractor. Please indicate below if you do not have a preferred contractor and require DW WiFi to recommend a company to install the Ethernet cabling. Do you have an Ethernet network? Are network HUBS used (as oppose to network switches)? Is it possible to route Ethernet cabling to all radio coverage areas? YES/NO please specify 7.2 Existing Wireless Networks The engineer will also need to be aware of any existing activity on the radio frequencies utilised by the wireless access points. All b and g access points operate within the ISM band (an unlicensed set of frequencies in the range GHz). Please can you identify ALL known wireless networks that are operational on your site. Where known, please can include the location, the manufacturers name, the ESS-ID and the radio channel. WLAN Location Manufacturer ESS-ID #1 #2 #3 #4 Radio Channel 7.3 Radio Interference Finally, please can you ascertain whether there are any other forms of equipment on site operating with the frequency range ( GHz). This is potentially a source of interference to the wireless access points. Source #1 #2 Type (eg DECT Phone) Frequency Range Location Version 1.15 Page 12

13 7.4 Coverage Area Details The survey engineer will require a site plan on the day of the survey. We request that several copies be made available (preferably no larger than A3 in size). We ask that the areas requiring radio coverage to be marked onto the plan (either shaded or outlined). Please can you answer the following questions specific to the required coverage areas and their environmental conditions: Item Please Indicate Make available during survey Site Plan of all coverage areas (max A3 size) Confirm that coverage areas will be fully accessible during survey Confirm general lay out and content is typical ( no planned layout changes) How many buildings are required to be covered Are there multiple floors / mezzanine levels required to be covered Are the areas to be covered in separate buildings Approximate size of areas to be covered (number of football pitches) Are there any Cold Store / Chiller areas requiring coverage At what temperatures do the Cold Stores / Chillers operate at Are any areas subject to excessive Moisture or Dust Are there any External areas requiring coverage Approximate size of areas to be covered (number of football pitches) Are there any Intrinsically safe areas requiring coverage Do you require a resilient (redundant) solution 7.5 Further Information Please detail any other information you may feel is pertinent to the wireless survey.
