Pre-Survey Questionnaire

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 802.11 standard. Advances have also been made in other areas. Currently 802.11g 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.

3 Purpose & Scope

The remainder of this document aims to compile sufficient information to carry out a Professional Radio Site Survey of your site(s).

Section 3 Site Details Specifics of your site or sites including designated members of staff who

must be present at the time of the survey.

Section 4 Access Requirements Details are required as to the rules and regulations of your site.

For example please state if PPE is required and whether this is provided by the site.

Section 5 Survey Requirements Details the wireless project requirements (type of access point,

required link speed, areas requiring coverage etc).

Section 6 Site conditions It is important that the survey engineer is made aware of any conditions

specific to your site that may impact on either the survey or the functionality of the proposed wireless LAN.

Section 7 Customer Signoff Please complete this section prior to returning via FAX, POST or

E-MAIL to DW-WiFi. An accurate quotation can then be provided together with some proposed dates for the Site Survey

6 Survey Requirements

6.1 Access Point Selection

Please note that all CISCO access points support the following radio standard and supports both 802.11b and 802.11g clients.

2.4 GHz IEEE 802.11g Direct Sequence Spread Spectrum Radio

Please be aware that in a ‘mixed cell’ environment (i.e. both 802.11b and 802.11g clients operating in the same coverage cell) the performance of the 802.11g clients will potentially be restricted to 802.11b 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

Version 1.15 Page 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.

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 802.11b/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.

Connection Type

Minimum Recommended Link Speed (across radio interface)

Tick Box as required

5250 Emulation (AS400) 2Mbps and above 802.11b/g PC Clients 2-54 Mbps (depends on usage)

Not Known

If the connection type proposed for your wireless project is not in the list please specify below with a description.

Pre-Survey Questionnaire

Version 1.15 Page 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

Tick Box as required 2 Mbps

Suitable for terminal emulation clients

11 Mbps 802.11b PC Clients

54 Mbps 802.11g PC Clients

Other (please specify)

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.

Area #1 Description Minimum Link Speed (Area #1) Area #2 Description Minimum Link Speed (Area #2) Area #3 Description Minimum Link Speed (Area #3) Area #4 Description Minimum Link Speed (Area #4) Area #5 Description Minimum Link Speed (Area #5)

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.

YES/NO please specify 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?

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 802.11b and 802.11g access points operate within the ISM band (an unlicensed set of frequencies in the range 2.40 - 2.4835 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.
