Altai A2e: Um Dispositivo WiFi de Alta Capacidade para Sistemas Super WiFi de Altai, Notas de estudo de Eletrônica

O Altai A2E é um dispositivo WiFi de ponto a ponto/ponte a múltiplo ponto, compatível com as normas 802.11a/b/g. Pode ser usado como ponto de acesso autônomo com cobertura direcional. Com antena de ganho de 2,4 GHz integrada, oferece cobertura de longo alcance de forma simples e econômica. Quando a capacidade de uma rede coberta pela estação base Altai A8 precisa aumentar, o A2E pode ser usado para dobrar a capacidade de usuários ou aumentar a taxa de transferência em seis vezes. Pode ser instalado onde a demanda é maior, com rápida conexão Ethernet ou rádio de retorno de chamada de 5 GHz. Permite aproveitar as economias de custo da estação base Altai A8 e aumentar a cobertura e capacidade conforme necessário.

Altai A2e

WiFi Access Point/Bridge

(802.11n capable)

The Altai A 2 e WiFi Access Point/Bridge is designed

to be used in Altai Super WiFi systems as high

capacity directional access point and long range-

bridge with flexible external high gain antennas. It

is capable of providing the highest possible data

throughput and capacity that the 802.11n

standards can offer, and at the same time is

backward compatiable to standard 802.11a/b/g.

The A2e can be used as a standalone access point

for directional coverage. With built-in 2.4 GHz high

gain panel antenna, it can be used to provide

simple and cost effective long range sector

coverage. The single-sided coverage makes

installation simple by just mounting at building wall

side.

As the system capacity of a network covered by

the A8 Super WiFi Base Station needs to increase,

the A2e Access Point/Bridge can be used to double

the user capacity, or to increase the network

throughput by 6 times supported by the 11n. The A2e

can be installed exactly where the capacity

requirement is the greatest, with appropriate fast

Ethernet or 5 GHz wireless backhaul. As a whole, it

enables network operators to take advantage of the

cost savings provided by the A8 Super WiFi Base

Stationís 10X greater coverage area when a WiFi

system is initially installed, and to subsequently

enhance the coverage and capacity where and

when it is needed.

The A2e Access Point/Bridge has both a high

capacity 2.4 GHz (2x2 802.11bgn) broadcast radio

and a 5 GHz (2x2 802.11an) backhaul radio. The 5

GHz radio provides 2 external antenna ports

connection which allows user to choose exactly the

type of high gain panel antennas they wanted for

distance and throughput exceeding what A2ís built-

in antenna allows.

A2e Access Point/Bridge provides the most cost

effective and versatile way to build the backhaul

network and to enhance a WiFi system capacity.

When combined with the A8 Super WiFi Base Station,

it can create possibly the most cost-effective high

capacity WiFi network system.
