C H A P T E R 2 An Overview of the Wireless Network With the introduction of wireless communication, mobile wireless IP phones can provide voice communication within the corporate wireless local area network (WLAN). The Cisco Wireless IP Phone 7920 depends upon and interacts with wireless access points and key Cisco IP telephony components, including Cisco CallManager, to provide wireless voice communication.
Chapter 2 An Overview of the Wireless Network Understanding the Wireless LAN WLANs require access point devices that receive and transmit radio signals. Cisco Aironet Access Points, such as the 1200, 1100, and 350 series models, support voice on a WLAN. Figure 2-1 shows a typical WLAN topology that incorporates wireless data for laptop computers and wireless IP telephony (WIPT) for Cisco Wireless IP Phone 7920 models.
Chapter 2 An Overview of the Wireless Network Understanding the Wireless LAN LAN communications and is commonly called WiFi. The 802.11b standard specifies the radio frequency (RF) of 2.4 GHz for both transmitting and receiving data at speeds of 1, 2, 5.5 and 11 Mbps. The 2.4 GHz RF range is an open frequency range that does not require licensing.
Chapter 2 An Overview of the Wireless Network Understanding the Wireless LAN broadcasts on a specific channel within the available channel range. To provide a stable wireless environment and reduce channel interference, you must specify non-overlapping channels for each access point. The recommended channels are 1, 6, and 11 in North America. The access point has a transmission range or coverage area that depends on its type of antenna and transmission power.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network Through stronger encryption algorithms, stronger authentication, and rapid key updates, WPA has significantly improved security compared to WEP. Wireless clients, such as wireless IP phones, can authenticate at either the access point or with the network by using a centralized remote authentication dial-in user service (RADIUS) server.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network Networking Protocols Used with Cisco Wireless IP Phones Cisco IP Phones support several industry-standard and Cisco networking protocols for voice communication. Table 2-1 provides an overview of the networking protocols that the Cisco Wireless IP Phone 7920 supports.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network Table 2-1 Supported Networking Protocols on the Cisco Wireless IP Phone 7920 (continued) Networking Protocol Purpose Usage Notes Internet Protocol (IP) Messaging protocol that addresses and sends packets across the network. To communicate using IP, network devices must have an assigned IP address, subnet, and gateway.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network Table 2-1 Supported Networking Protocols on the Cisco Wireless IP Phone 7920 (continued) Networking Protocol Purpose Usage Notes Wi-Fi (802.11b) An open standard that defines wireless methods of transmitting Ethernet traffic and is commonly called Wi-Fi. This standard defines radio frequencies (RF) and data speed for wireless LAN communications. Cisco Wireless IP Phone 7920 uses the 802.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network cause the page to display slowly and might annoy the end user. However, packet loss during voice transmission can cause choppy or broken audio and make the phone call inaudible. Wireless voice users are mobile and can roam across a campus or between floors in a building while they are connected to a call. Alternately, data users might move their PC to another location, but they reconnect at the new location.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network • QoS Basis Service Set (QBSS)—The access point uses this beacon information element (IE) to send the channel utilization of the access point to the Cisco Wireless IP Phone. The phone uses the QBSS value to determine whether the access point can effectively handle more traffic.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network points are in the same Layer 2 subnet, the Cisco Wireless IP Phone keeps the same IP address and the call continues. As a Cisco Wireless IP Phone roams between access points, it must re-authenticate with each new access point. See the “Security Mechanisms in the Wireless Network” section on page 2-13 for information about authentication.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network • Interacting with the Cisco Aironet Access Point, page 2-8 • Wireless Network and Access Point Configuration, page 2-19 Voice Quality in a Wireless Network Voice traffic on the Wireless LAN, like data traffic, is susceptible to delay, jitter, and packet loss. These issues do not impact the data end user, but have serious implications for a voice call.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network Security Mechanisms in the Wireless Network Before a wireless device can communicate on the network, it must authenticate with the access point or the network by using an authentication method. The Cisco Wireless IP Phone 7920 can use these authentication methods in the WLAN: • Open Authentication—In an Open system, any wireless device can request authentication.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network Cisco LEAP is a proprietary authentication protocol that requires a LEAP-compliant RADIUS server. LEAP allows wireless devices to mutually authenticate by using a username and password through a centralized RADIUS server user database. When a Cisco Wireless IP Phone roams from one access point to another, the next access point requires LEAP authentication, also.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network • WEP —When using WEP in the wireless network, authentication happens at the access point by using open or shared-key authentication. The WEP key that is setup on the phone must match with the WEP key that is configured at the access point for successful connections. The Cisco Wireless IP Phone 7920 supports WEP keys that use 40-bit encryption or a 128-bit encryption and remain static on the phone and access point.
Chapter 2 An Overview of the Wireless Network Components of the VoIP Wireless Network When using Authenticated Key Management (AKM) for the Cisco Wireless IP Phone 7920, several choices for both authentication and encryption can be set up on the access points with different SSIDs. When the Cisco Wireless IP Phone attempts to authenticate, it chooses the access point that advertises the authentication and encryption scheme that the phone can support.
