facilities to be better utilized, new
ERP and CRM initiatives to be
deployed, costs to be better
managed
• Growing use of dual-mode phones,
video, RFID, and PDAs must be
accommodated
By 2007 more than 66 percent of workers
will use mobile and wireless computing,
and that number will rise to 89% in 2008.

5. Productivity growth drives profitability and
holds the line on costs
• Productivity improvements drive
growth, raise profitability, and
control costs by allowing small IT
staffs to make the most of
available resources
• Wired networks don’t address
mobility needs, are costly to
modify
• A low-overhead networking
platform lowers costs by making
small IT staffs more productive
A 1,000 employee retailer could realize
$800,000 in savings from a 1% increase
in productivity.

6. Reliable WLANs are the cornerstone of
information conduits
• Reliable conduits using
converged voice/video/data
encourage knowledge transfer
•
and collaboration
Retailers have dense, dynamic
99.9999%
user environments and mixed Up Time
clients
• Proprietary software/drivers are
anathema to IT management
A highly reliable WLAN allows a small
IT staff to focus attention on
productivity and growth-related
opportunities instead of infrastructure-
related problems
6

7. Interoperable solutions overlay on existing
infrastructure, preserve capital
• Retailers must squeeze higher
returns from existing assets while
paving the way for new applications
• Solutions must be easily deployable,
optimized for converged toll-quality
voice/video/data, and able to
withstand harsh environments such
as warehouses
Even if the initial use is for data, a WLAN
must support converged data, roaming
voice, and streaming video applications
because they will be needed in the future
7

8. The TCO of an IT solution can help or
hinder strategic educational objectives
• Lower total cost of ownership
(TCO) should be a key objective
of any IT infrastructure change
because it determines where
future funds will be directed
• Dynamic and rapidly evolving
retail environments require
flexible, adaptable solutions Source: Gartner Group
Loss of productivity and heightened
frustration due to IT equipment downtime
are factors in assessing TCO

25

26. Phone: Cisco phones work better on
Meru’s networks
• Cisco wireless phones work better on Meru’s networks
• Toll-quality voice while roaming, dynamic control of over-the-air communication
• WPA / WPA2 Enterprise Mode with zero hand-off, a Meru exclusive
•
High QoS voice in converged data/video networks, no need for parallel networks
•
High density operation with more clients per Access Point, lowers costs
In WLAN tests using Cisco 7920 phones + Cisco Unified CallManager®,
Meru supported 10 simultaneous calls with MOS scores >4,
Cisco supported 4 simultaneous calls with MOS scores <4.
• Other WLANs just weren’t designed for voice
• No contention management, no traffic management, no resource management, no
admission control, no upstream QoS reservation, no scalable QoS without additional
higher layer system software
•
Closely spaced Access Points aggravates co-channel interference, distant spacing
reduces coverage and channel access
• QoS is dependent on proprietary CCX client adapters - difficult to manage and
burdensome for guest access
26

27. Data: Meru’s networks offer higher density,
higher performance
• Meru has proven solutions for dense client and high throughput applications

30. Mobility metric
• Meru lets all users walk, talk, and surf - all at the same time
•
Users can roam reliably during voice calls, increasing their mobility as well as
their ability to multi-task
•
Cisco voice quality drops with >4 voice calls on the same Access Point. How
should this be managed?
• Scenario: department store with 150 staff members and dual-mode
phones
•
Average hourly staff wage: $40
•
Average calls per day requiring walk to the next task: 30
•
Average time to reach the next task after a call: 1 minute
• Cisco’s poor mobility results in 27,375 hours of lost time, or
$1,095,000 of lost wages per year
•
((1 min. x 30 tasks) / 60 min.) x 150 users x 365 days = 27,375 hrs
•
$40 hour x 27,375 hours = $1,095,000 (≈854,000€)
30

31. Productivity metric
• Meru leads the industry in the ratio of users-to-Access Points and
guaranteed access to bandwidth
• Cisco requires more APs in high-density environments, increasing equipment
and installation costs
• Scenario: warehouse with 200 staff with 802.11b/g laptops, all of
which must download a 5MB SKU update within five minutes
• Meru can download the data to all staff members in <5 minutes using 3 APs
Meru installation cost: 3 APs@$795 + 3 inst.@$500 = $3,885 (3,030€)
•
• Cisco requires >50 minutes using 14 APs to download the data
Cisco installation/survey cost: 14 APs@$899 + 14 inst.@$582 = $20,734 (15,918€)
•
• Staff members lose work time using a Cisco network, whereas with a
Meru network they can be productive in minutes
31

32. Connectivity metric
• Meru provides fair access to 802.11b/g clients
•
Cisco is slow to associate new clients + 802.11g throughput degrades in the
presence of b clients
•
Meru 18Mbps vs. Cisco 9Mbps with only 10 g clients and 1 b client
• Scenario: retailer with 2 Access Points and 25 inventory clerks who
must log-in their mixed 802.11b/g laptops at the start of a shift
•
Meru logs in all clerks in ≤3 minutes
•
Field data shows Cisco requires ≈6 minutes to log in each group of 4 clerks,
or (6 minutes x (25 / 4) students) 37.5 minutes for all clerks
• Clerks lost >35 minutes during log-ins using a Cisco network,
but only 3 minutes using a Meru network
32

33. Interoperability metric
• Meru’s WLANs work with standard clients, eliminating the need to
install, track, and update custom clients or adapters
•
Cisco requires proprietary CCX client adapters on every device for micro cell
power management - CCX patch management, RF tuning, and new client
troubleshooting are IT burdens
•
Cisco’s management tool points to a problem but doesn’t solve it – Meru
doesn’t have the problem to begin with
•
Non-CCX guest access requires a separate network
• Scenario: retail chain with 2500 clients (laptops, PDAs, phones), 40
sites, 200 vendor visitors per month
•
Average time to load/verify Cisco CCX adapter: 30 minutes each
•
Churn rate (new/replacement devices): 5% (125) per month
• 1st year overhead managing Cisco client adapters: 2000 hours
•
(2500 clients x 30 min.) + ((125 clients x 30 min.) x 12 mos.) = 120,000 minutes or 2000 hours
33

34. TCO metric
• Meru’s Air Traffic Control technology minimizes the need for RF
channel planning
•
Cisco requires RF planning to avoid adjacent channel interference, and more
APs to provide adequate coverage, adding cost and complexity
• Scenario: 100 room home furnishing superstore (100,000 sq. ft. total),
each room must be covered by 2 APs for seamless roaming (20 APs
required in total )
•
Cisco survey time is >4x longer than Meru
• IT productivity for surveys is 1 hour per 7,040 sq. ft. with Cisco,
productivity with Meru is 1 hour per 32,260 sq. ft.

37. Meru has a track record of helping
customers meet their strategic objectives
"WLAN connectivity allows organizations to cost-effectively support on-campus
workers with voice and data applications that can significantly improve
communications and workflow inside the enterprise," said David Werezak, Vice
President, Research In Motion. "Meru's WLAN infrastructure with its reliable
connectivity and seamless coverage provides a solid foundation for the
BlackBerry WLAN solution."
To provide wireless coverage, SUNY Farmingdale deployed Meru access points
spaced only 30 feet apart from each other. Gladson George, Network Administrator,
SUNY Farmingdale, said, "This high density set-up would not have been possible
without Meru's unique Air Traffic Control technology. With Meru's ability to
coordinate all of the access points in this area and successfully manage signal
contention, we can deliver wireless access in the most demanding of environments."
“We evaluated several wireless LAN products, but when we saw Meru’s
demonstration, our decision was easy,” said James Pierce, Chief Information
Officer, The Monitor Group. “We were able to configure and deploy the
system, with consistent security and access policies, in a matter of
minutes…Meru’s ability to handle multiple data applications, as well as voice,
to meet our future needs, convinced us that Meru was the only WLAN
solution that made sense.”
