What about DECT!?
Borderless Mobility: CUWN TDM © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential
Digital Enhanced Cordless Telecommunications (DECT)
Protocol sponsored by ETSI for devices operating in the 1880 MHz–1930 MHz frequency (range depend on country)
Originally developed in 1992 for Europe but was adopted globally in Europe, Asia, Australia, South America, and the US
DECT solution offering extend to include:
Consumer cordless telephony with a single base station
Enterprise cordless PABXs using many base stations for coverage.
Public access, using large numbers of base stations to provide building or urban
World Enterprise DECT Phone Markets earned revenues of over of $280 million in 2007 and estimates this to reach $318 million in 2014
Sales of single mode devices is being challenged by the economic downturn and the increased growth of smartphone dual mode devices
Borderless Mobility: CUWN TDM © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential
DECT Vulnerability
Cheap laptop-based sniffer that can break into DECT cordless phones to intercept calls and information directly, and recording it in digital form. This enables anyone to sniff and archive DECT traffic (voice and/or data).
The interception can be applied to system with or without encryption. The system can bypass encryption - simply by pretending to be a base station that doesn't support it.
The attack on DECT, demonstrated at the 25th Chaos Communications Congress in Berlin on 29 December, used a Linux laptop with a modified €23 laptop card.
DECT's use of a secret encryption algorithm contributed to the problem - hence not been subject to scrutiny by outside experts

Design Your Wireless Network To Be ―Voice-Ready‖
Cisco White Paper Design Principles for Voice over Wireless LAN”
http://wwwin.cisco.com/marketing/mobility/solutions/vowlan/files/designprinciplesforvoiceoverwlan_v1.pdf
VLANs Voice should be on a separate VLAN from data
QoS Need over the air, end-to-end QoS (Clients, AP‘s, Controllers, Switches, Routers)
AP Coverage Overlap coverage areas to facilitate roaming
Monitor Interference
Use WCS to control and manage RF in realtime
Capacity To handle voice+data load, use more AP‘s, and reduce transmit power
802.11a Leverage the non overlapping channels and high data rate of .a
CCX Version 4.0 Ensures high performance voice clients

Find Out What Other RF Devices are at the Site
Borderless Mobility: CUWN TDM © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential
Ideal Environment for 802.11b/g/a/n phone clients the cell edge recommendation is -67dBm. A typical deployment showing a 10–15% overlap from each of the adjoining
cells. Provides almost complete redundancy throughout the cell.
With 5GHz there are enough channels available there should be no need to have a co-channel design, but this would the recommendation for dense 5GHz deployments and for all 2.4GHz deployments
The same design principle applies for deployments using 802.11n APs.
The separation of
same channel cells
should be: 19 dB
-67dBm -86dBm
The RADIUS
of the cell
should be:
–67 dBm
Channel 36
Channel 44
Channel 149
Channel 1
Channel 6
Channel 11
or
This example shows just 3 of the 5GHz 11a or bounded 11n channels.

SITE SURVEYS ARE CRITICAL– Sample Best Practices
RECOMMENDATIONS
Site Survey ToolsSite survey tools are available from Cisco, and 3rd
parties such as AirMagnet, that can also be used to provide additional detailed information
RF Recommendations RF walkthroughs should be performed to identify and mitigate sources of non-802.11 RF interference and rogue access points (automated tools available)
Values and specifics required for successful voice deployment are documented in deployment guide

What is channel utilization ?
It is the amount of RF energy that is on a channel time wise
This is no standard algorithm for computing channel utilization (CU)
–This means comparing the CU of one utility against another is likely to show different values
–Also the difference is most likely to be from how long the different utility sampled the channel for energy
There is a channel utilization Standard known at ‗Aloha‘ which states that a wireless channel with packet data is fully utilized with the CU has reached 36%

Spectrum Expert – Channel Utilization
Borderless Mobility: CUWN TDM © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential
What can we do to reduce CU?
Infrastructure filters to remove un-needed protocols from the WLAN
– What WLAN would need the protocol LAT
Manage Multicast traffic
Remove when possible lower data rates
Remove higher transmit powers
Use dynamic transmit power control DTPC
Use latest client drivers
Use diversity antenna solutions
Borderless Mobility: CUWN TDM © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential
Some Layer 1 installation – Don’ts!!
Don‘t mount antennas so that they transmit directly in to metals or other highly reflective surfaces!!
Borderless Mobility: CUWN TDM © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential
NOT!!
Don‘t mount the AP1130/AP1142 horizontally. It doesn‘t become a patch antenna solution.
Borderless Mobility: CUWN TDM © 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential
NOT!
This creates a ton of mulitpath and hides the AP from clients
