Extreme Networks Data Sheet

Superior Wireless Performance

Altitude 4600 series APs deliver a six-fold

increase in throughput over existing

802.11a/b/g legacy LANs. The 2x3 MIMO

with dual spatial streams, along with

Orthogonal Frequency-Division

Multiplexing (OFDM) modulation, enables

the AP to deliver full 802.11n performance.

An Altitude 4600 AP and an 802.11n client

can bond two adjacent 20 MHz channels to

create a single 40 MHz wide channel. This

potentially doubles the throughput from a

standard 20 MHz channel. Gigabit Ethernet

connectivity to the wired network enables

full speed access to the wired network.

The powerful 24 dBm radio increases

coverage, performance and obstruction

penetration versus lower dBm radios. In

addition, receiver sensitivity has been

increased proportionally so users have an

increased ability to maintain high-

performance access through thick doors

and walls to users even while on-the-move.

The Altitude 4600 series APs 2x3 MIMO

design ensures premium transmit and

receive communications.

Ease of Deployment

and Operation

Altitude 4600 series APs offer a superior

return on investment when considering the

total costs of upfront capital expenditure,

network upgrades, installation, and

operation. Flexible mounting options with

built-in mounting brackets for wall or

ceiling mount are available. The APs

conform to the 802.3af PoE standard while

delivering the full 802.11n performance.

This preserves the investment in existing

PoE infrastructure and eliminates the need

to power each AP separately.

Altitude 4600 series APs require no

conﬁguration or manual ﬁrmware mainte-

nance. The Summit WM3000 series

controller discovers the access points on

the network and automatically downloads

all conﬁguration parameters and ﬁrmware,

greatly reducing installation, maintenance

and troubleshooting costs for Layer 2 and

Layer 3 deployments.

Locationing services over 802.11 net-

works provide the ability to locate and

track people or assets, and even to

control access to the network or applica-

tions. In addition, it is easy to provide

hotspot and guest access and assure the

user can only access authorized networks,

sites or applications.

Enterprise-Grade

Wireless Services

The Altitude 4600 series APs support

over-the-air QoS protocol based on

802.11e/WMM speciﬁcations. The APs

also support standards-based (802.11e)

Unscheduled Automatic Power Save

Delivery (UAPSD/WMM Power Save) that

extends the battery life of hand-held

client devices like VoWLAN handsets. It

enables fast secure roaming using several

mechanisms including pre-authentication,

opportunistic key caching, and WPA2

based PMK caching.

The Altitude 4600 series APs provide low

latency support for the industry-leading

VoWLAN devices. The APs support

over-the-air QoS protocols such as

SpectraLink Voice Priority (SVP) and

802.11e based WMM speciﬁcations.

Priorities can be set according to SSID,

allowing critical real-time voice trafﬁc to

be assigned to a distinct high-priority

queue. Interoperability with wired

network trafﬁc prioritization ensures

end-to-end QoS as the trafﬁc traverses

the network.

Common problems such as building

attenuation, electronic interference or

sub-optimal access point placement are

minimized as the SMART RF feature

automatically optimizes power and

channel selection so that each user gets

always-on high-quality access and mobility.

Comprehensive Security

Altitude 4600 series APs offer a high level

of security features for wired and wireless

connectivity. The APs supports stan-

dards-based, over-the-air encryption

schemes to protect the integrity of user

data. The APs participate in wireless client

authentication using 802.11i standards-

based WPA or WPA2 mechanisms. The APs

also participate in its own authentication

with the wired switch port using 802.1X.

They can support several security proﬁles

based on application. On-board hardware

accelerated encryption engine supports

WEP, TKIP and AES standards. Unique

security proﬁles can be conﬁgured on a per

SSID basis.
