Cisco offers a range of wireless, DECT, and Bluetooth headsets that connect to your desk IP phones, softphones, or mobile devices. They provide a stable connection enabling workers to stay focused on the work at hand while offering a great mobile audio experience. By combining with the market-leading Cisco® Unified Communications (UC) architecture, Cisco Headsets offer advanced integrated manageability functions unlike any other in market today.

While wireless headsets can help increase workplace productivity, incorrectly deploying wireless headsets can have the opposite affect and significantly increase the frustrations of staying connected. This white paper is intended to help you to understand the different wireless technologies and provide general guidance on how to deploy the Cisco Headset 730 and the Cisco Headset 500 Series together. However, this white paper is not intended to replace our existing Cisco Headset 560 DECT deployment guide. For more information on Cisco 560 DECT deployments, please refer to the DECT deployment options for the Cisco Headset 560 Series: cs.co/dect

Blueooth versus DECT

Workplace transformation is happening everywhere, across all industries and countries. The way we work is rapidly changing in this globally connected environment with an expansion of devices utilized. New ways of collaborating are at the core of the transformation.

When evaluating headsets it is important to consider several factors such as:

      Location requirements: Will the headset be used exclusively in a traditional work office, a remote home office, or both?

      Density: Will this be in an office with many other headsets, or hardly any?

      Range: How far is the person expected to roam away from the endpoint they are paired to?

      Mobility (smartphone): Is headset connectivity required on the go?

      Potential interference: Physical characteristics of the building itself are important such as floorplan, material in walls, etc. Likewise, so is co-existence with wireless access points, other Bluetooth devices, etc.

Introduction to Bluetooth and the Cisco Headset 730

The Cisco Headset 730 is a wireless headset that uses Bluetooth 5.0. The Cisco Headset 730 ships with an optional USB adapter. You can pair the Cisco Headset 730 to devices using the native Bluetooth built into the PC. Alternatively, you can use the USB HD adapter. There is also an optional base station accessory for the Cisco Headset 730. However, the base does not utilize radio technology to send and receive audio signals with the headset, and is only used for power charging.

The challenges

Too many headsets in a confined space can generate radio interference that result in a poor audio experience. Advanced planning is highly recommended before deploying a lot headsets in a limited space.

Facts about Bluetooth density

When multiple Bluetooth devices operate in close proximity, they share the radio spectrum which can result in interference between devices. Headset density defines the number of headsets that can be used simultaneously in a given area without interference. It’s critical to plan headset density for a given area in advance to guarantee a successful deployment.

Bluetooth technology is based on an unlicensed radio frequency band and there are many environmental variables that play parts in determining its quality. Following is only a short list of them:

      Average distance between headsets

      Call utilization (the amount of time in which the headsets are in a call)

      Wi-Fi deployment and configuration

      Roaming range (mobility)

      Office size and layout

      Office furnishings - furniture, walls, dividers, carpets, curtains, metal objects, glass surfaces, etc.

Table 2 outlines some examples of different materials and their radio attenuation.

Following are some general suggestions for positioning Bluetooth headsets:

      Deploy as evenly as possible in a given area to ensure the distance between the headsets for least interference. Cisco recommends a minimum of 1.2 meters (4 feet) between headsets.

      Every deployment is unique so reach out to your Cisco representative to guide you through the specifics of your deployment.

Cisco Headset 730 deployment planning

Appropriate planning is key to a successful deployment. This section covers the steps on helping you plan your deployment.

Step 1.         Cisco wireless headsets are a part of a larger Cisco UC and Collaboration experience. To get the best experience possible, make sure the minimum system requirements are met.

Table 3.        System requirements

Name

Version

Cisco Headset 730

2.0 or higher

Cisco Unified Communications Manager

All versions support basic audio. Upgrades and management require 11.5(1)SU7+ or 12.5 (1)SU1+

Cisco IP Phone 7800 & 8800 Series

12.7 or higher

Cisco Jabber® - Desktop

12.7 or higher

Webex TeamsTM (Windows or Mac)

Current

Step 2.         Familiarize yourself with how to adjust the headsets’ settings that can impact your deployment.

Step 3.         Survey the space where the Bluetooth headsets will be deployed.

      Identify the floor layout

      Find the size of the space, width, and length

      Mark any obstacles, e.g. metal object, large glass surfaces, etc., and remove them if possible

      Locate any potential interference sources, e.g. other 2.4 GHz sources being utilized on adjacent floors

      Stage the deployment on the floor layout

      Identify Bluetooth interference sources in the environment

Table 4.        Factors to consider

Factor

Description

Wi-Fi and Bluetooth traffic in 2.4-Ghz band

Devices in close proximity competing for RF channels in the 2.4-Ghz band may reduce Cisco Headset 730 deployment densities. Unfortunately, such devices are common in businesses. They include Wi-Fi access points, laptops, keyboards and mice, mobile phones, and IoT devices, all of which take up available bandwidth.

Clutter

Room furniture, materials, and office equipment around the headsets can all reduce RF transmission ranges of Bluetooth devices.

Room layout

Walls, glass, ceiling materials, hallways and can result in more RF reflections (and thus noise) in the 2.4-Ghz band. The factors may reduce Bluetooth density.

Step 4.         Prepare headset training material for end users based on your deployment goal. For more information:

      Cisco Headset 730 User Guide

      Cisco Headset 730 Administration Guide

Typical deployment scenarios

Deployment recommendations vary based upon end user requirements. This section provides recommendations based upon three typical workspaces: 500 square meters, 1000 square meters, and 1500 square meters. The recommendations are based upon mobility, the size of the office, and the total number of active users. Most deployments fall into one of these three workspaces and further adjustments can be made to accommodate variations.

Deployment option A: Deploying only Cisco Headset 730

If you want to maximize the number of deployed Bluetooth headsets, use the recommendation outlined in Table 5. Note: This recommendation does not account for Wi-Fi interference or other inferences in the 2.4-GHz frequency. Cisco recommends using the results of the site survey to determine interference locations and evaluate all the deployment options listed in this guide, inclusive of DECT before a production deployment.

Table 5.        Recommendation for only deploying the Headset 730

Area in square meters

Maximum number of headsets

Minimum spacing between headsets [meters]

500

Up to 75

1.2 m for deployment of less than 35 headsets 2.6 m for deployment of 38 to 75 headsets

1000

Up to 110

3.0 m for deployment of 76 to 110 headsets

1500

Up to 150

3.2 m for deployment of 110 to 150 headsets

Deployment option B: Mixed deployment of Cisco Headset 730 + Cisco Headset 500 Series

If you want to deploy more headsets in a given area than specificed in Table 5, we recommend layering or interweaving the wired Cisco Headset 520 and/or 530 Series with the Cisco Headset 730. Alternatively, you can deploy the wireless, DECT Cisco Headset 560 in the same area as Cisco Headset 730 without any interference. Please consult the Cisco Headset 560 DECT deployment guide for details: cs.co/dect
