Subject:      Vocera Communications STA Application,
              Public Exhibit I
Date:         5 March 2007

Gentlemen,

An STA is being sought for the “Beta” testing of a IEEE802.11 B/G “VOIP” communication
system.

This is the second generation of a current product already certified with the FCC under FCC ID:
QGZ-B1000A

Testing of the product within the engineering labs at Vocera Communications has been
completed. In order to further the development of the product and verify its performance in a
“real world” environment, Vocera Communications is seeking an STA to allow it to conduct
verification tests outside of the engineering lab environment.

The necessity for an STA is not expected to be longer than 6 months. This document addresses
some of the Commissions concerns regarding experimental licenses / STAs.

If additional information / clarification is required, please do not hesitate to contact me.
Regards,




David Waitt
Consultant Representing Vocera Communications

Company Background
Vocera Communications,® Inc., has developed a wireless voice communication system to
enhance customer service, productivity, and teamwork throughout organizations. The company,
headquartered in Cupertino, Calif., was founded in March 2000 by a team of technology
professionals with years of experience designing complex network-based software and
hardware systems.

Overview / Applications of the Vocera Communications system.




The Vocera Communications System enables instant, wireless voice communication that users
control with naturally spoken commands. This easy-to-use system is ideal for hospitals, hotels,
retail stores, and other in-building environments where mobile workers need to stay in contact to
perform their jobs. The Vocera Communications System provides wearable, voice-controlled
communication via an 802.11b wireless LAN.
Using voice prompts, Vocera instantly connects users to the people they need, thereby reducing
phone tag, overhead paging, or the need to physically search for a person


                The Vocera Communications Badge
                The communications badge is a lightweight, wearable, voice-controlled device
                that operates over an 802.11b/g wireless LAN infrastructure. It enables instant,
                handsfree conversation. The badge interfaces with the Vocera Server, where the
                system’s intelligence is housed. The system can also connect to the PBX in
                order to place and receive calls through the public telephone network. Together
                the Vocera System Software and Vocera Communications Badge allow people
                to instantly communicate with others throughout a building or campus
                environment.

Reason for Experiment
Complete program of research and experimentation proposal including description of
equipment and theory of operation:
Second generation badges will be distributed at several campuses that are already using the
first generation of the Vocera system. This will allow users who are very familiar with the
performance to judge the performance of the new badges.

Applicable Rules and Standards
The proposed system meets the requirements of FCC Part 15.247 ( “Operation within the bands
902 - 928 MHz, 2400 - 2483.5 MHz, and 5725 - 5850 MHz.“ The product will be FCC certified
under this rule part. The certification effort will begin approximately halfway through the Beta
test period.

Specific Objectives sought to be accomplished:
The main objective of the proposal is to verify acceptable performance of the Vocera
communication system in multiple “typical” business / educational / health care environments.
And to attempt to quantify the relative improvements over the previous generation of product

How the program of experimentation has a reasonable promise of contribution to the
development, extension, expansion, or utilization of the radio art, or is along the line not
already investigated:
The Vocera Communications System enables instant, wireless voice communication that users
control with naturally spoken commands. Advancements in available RF products and
components have enabled improvements within the communications badge. The successful
Beta test of the Vocera communications Badge will, in part, validate and verify these
advancements, thus allowing and encouraging these new RF products to be used in a wider
range of communications products.


Additionally, of course, a successful Beta test program will result in improved Vocera
Communications devices being available for hospitals, assisted living facilities, schools, libraries
and other public institutions.

   Location and Recovery of Test Radios
The location of the beta test locations and quantity of badges in use at each location is
considered Vocera confidential. Please see Confidential Exhibit I for a list of proposed locations.

The specific campuses in which the test will be conducted were chosen based for a variety of
reasons including:
    o Willingness of the staff to participate in the program and provide feedback to Vocera
    o Building type, floors, floor plan...
    o Usage of the products (typically “heavy”)
    o Density of supporting 802.11 infrastructure
...and other variables in order to characterize system performance in a wide variety of
environments.

Upon completion of the Beta experiments, all of the Beta test units will be returned to Vocera
Communications in California.

Labeling of Units:
The text shown will appear on a label that will be         This device has not been authorized as required by
                                                           the rules of the Federal Communications Commission.

“Portable” use of the badges:
The communications badge is classified by the FCC as
a portable device and as such and given its expected
transmit power requires SAR testing for FCC
certification. SAR testing will NOT have been
conducted by the time the Beta units are fielded for
trail.

Certainly RF exposure must be assessed during the
Beta testing. Vocera regulatory engineering has
determined that the RF exposure of the Beta
participants will be the same as those using the
generation I badge.

The SAR value of the Generation I badge was found to be well under the FCC limit (1.6W/Kg
averaged over 1 Gr). Given the RF transmit power of the generation 1 badge and the
Generation 2 badge, the expected SAR value of the Generation 2 badge is calculated below

Measured SAR, Gen 1:        0.0535 W/kg (1gr)        (FCC ID QGZ-B1000A)
Measured EIRP, Gen 1:       16.7 dBm
Assumed EIRP, Gen 2:        16 dBm
Calculated SAR, Gen 2:      0.0455 W/kg (1gr)        (Calc from Gen 1 results)
FCC SAR Limit:              1.6 W/kg averaged over 1gr


The persons testing the Generation 2 badges will be made aware that RF exposure has not yet
been tested on these devices, however the expected difference in RF exposure between the
two versions of the device is minimal and well below the FCC limits.

Possibility of Harmful Interference
The possibility of harmful interference from the Beta devices is no greater that the possibility of
interference due to the generation 1 devices. There have been no complaints of harmful
interference due to the prior generation of products, thus, is no reason to believe the Beta
device will cause any harmful interference

Proposed Certification Procedure
The Beta testing will help refine the Vocera Communications product, and allow it to move
forward with FCC Certification and bring this product to market as soon as possible. It is
anticipated that the system validation experiment will last for approximately 30 - 60 days.
Assuming that no major flaws are uncovered during the course of the experiment Vocera
Communications will begin the FCC certification process approximately mid-way through the
Beta testing.
