1 Project Overview

“Company” is a new type of storage company designed for a new world in which ever-increasing amounts of content are being generated from cloud services, Internet content providers, social networks and mobile devices. They focus on delivering innovative customized storage solutions and high level storage infrastructure consultation to some of the world’s largest and most sophisticated technology companies.

IT management requested an RF (Radio Frequency) site survey at multiple campuses throughout the world for an upcoming wireless proof-of-concept (POC) project. The main trigger points for the infrastructure overhaul revolve around new applications that will be deployed (i.e. Jabber/Lync), giving employees the ability to communicate with other people in the organization using voice/video services.

This report will consist of buildings B/C. Building B/C consist of 1 floor some areas in this campus belongs to another company and does not require RF coverage in all areas. This report will have documents inserted that are jpeg and other formats, the original working documents will be included in the “Company” designated “box” folder. This will allow more flexibility in moving the document(s) from one location to another.

This site was one of two of the first campus to be surveyed in this region and all of the other locations had representatives at this site for training, briefing, updates and overview of the survey process.

Air Magnet Surveyor Pro and Aruba AP 225 was used for the site survey(s).

The project requirements were pre-established via conference calls with management, prior to the site survey and are as follows:

1. Provide 100% coverage for all buildings identified to be surveyed at the multiple campuses on the 2.4 GHz (B/G/N) and 5 GHz (A/N) bands.

2. Ensure that lower-powered RF devices such as Windows Mobile, Android or IOS-based devices are still able to receive adequate RSSI for VoIP and video calls.

3. Conference rooms that have more than 4 chairs should have a dedicated AP. If there are multiple conference rooms next to each other, and/or very large meeting rooms, calculate potential user density first before adding an additional AP.

4. AP capacity planning was targeted at approximately 30 devices per AP. Management advised that up to 3 devices per user should be expected.

Site Description

The campus for the site survey consisted of the following buildings and floors.

o Building B/C – 1 floor – Not all of the floor required RF coverage. o Building D/E – 3 floors – not all of the 3rd floor required RF coverage o Building F – 2 floors – not all of the floor for each level required RF coverageo Building G - 4 floorso Building K - 3 floors – On 3rd floor there is one classroom for RF coverage – Café is also located in this building

The facility is described as follows:

o Indoor area with offices, and clean rooms o Building B/C consist of 1 floor with offices, and clean room, o All access points (APs) will require a mounting bracket for installation.o There were multiple locations the surveyor was able to get into for the purpose of the site survey and is

annotated on the AP spreadsheet; o The ceiling heights are generally between 8-12 feet in most areas.o The physical conditions of some of the buildings were different from the drawings provided and created

some delays in the process.

Environmental Conditions

This section documents general environmental properties or conditions at the time of survey:

o No abnormal hot/cold areas were either observed or reported.

Current RF Usage

This section documents any RF equipment either disclosed by the client or located by through RF sniffing tools:

o Numerous rogue AP’s detected by Air Magnet in many of the surveyed areas.o Lab areas contain numerous types of high-powered electronic testing equipment and may cause some

RF interference, especially in the 2.4 Ghz band and as part of the fine tuning process during the installation, may need to turn off some of the 2.4 GHz radios.

o There were areas that were not available to the surveyor (conferences on going, doors locked, meetings, etc.).

o AP locations and any special mounting instructions are annotated on the AP spreadsheeto All the ceilings in this campus are hard ceilings and will require additional mounting bracket for

installation.

Special Requirements

Helpful instructions or advisories for the installer:

o A scissor lift may be required for the installation.o Customer will be providing AP power via a PoE-capable switch. o Switch capacity planning and AP switch termination is to be determined by IT department. o This report does not include the Individual Distribution Frame (IDF) closet or switch which the AP will be

terminated or connected to.o A floor plan with the Access Point (AP) locations have been provided with Microsoft Visio as well as AP

location information on Microsoft Excel spreadsheet(s).

3 RF Propagation Testing

Site Survey Approach

Signal propagation is determined by temporarily mounting an access point in the ceiling and measuring the coverage area that the access point was able to provide.

o An Aruba AP model AP225 was used for RF testing.

o The access point receives inline power using a standard Ethernet cable. By using inline power, a separate power cord is not required to connect to the access point. The Ethernet cable is plugged into the Ethernet port on the back of the access point and the opposite end is connected to the inline power source (PoE injector).

o The Air Magnet software takes automatic samples of the RF environment and plots them on the map as indicated by the user. Certain areas of the facility were not accessible due to either clean room restrictions, in conference, meetings, training at time of survey, or security related mandates. However, more than enough samples were obtained to demonstrate recommended RF propagation based on the project requirements.

The AP cells have been separated out at an RSSI value of -62 to ensure that smart phone devices and other low-powered devices are able to use the system issue free. This coverage zone is established by measuring the shortest distance the desired value is sampled from; usually referenced by the amount of interfering objects in between.

The average distance that this value was determined at for this location based on the survey points was between 70-85 feet. However, AP density is also related to the amount of users for any given area. Since wireless transmissions are half-duplex, throughput is relative to how many client transmissions are occurring with the AP.

Because the requirements for this project included 100% coverage in the 802.11A/N band, the survey was focused specifically in this area, since the power output is FCC limited at half of its 802.11 B/G/N counterpart.

4 AP Recommendations

The AP cells have been separated at an RSSI value of -62 to ensure that smart phone devices and other low-powered devices are able to use the system without issues. These devices often use power saving algorithms which can cause the Tx power to be significantly lower to preserve the device battery life.

Coverage zones are established by measuring the shortest distance where the established RSSI value is sampled usually based on the amount of interfering objects in between the AP and the client. The average distance that this value was determined for most locations was between 70-90 feet. The average distance that this value was noticed was between 70-85 feet from the AP.

However, AP placement is also related to the amount of users for any given area. Since wireless transmissions are half-duplex, throughput is congruent to how many client transmissions are occurring with the AP at any given time. In the cubicle offices, typically more AP’s are added, and special attention is made to trim Tx power to prevent excessive channel overlap.

The following is list of number and model access point for each building and floor. For this campus:
