Chapter 1 Getting to Know Your ExpWave

This chapter introduces the main features and applications of the ExpWave.

1.1 Introduction to the ExpWave 240B

The ZyXEL ExpWave 240B (ExpWave 240B) is a Wireless Bridge/Router for Inter-building Point to Point Ethernet connection. With integrated IP routing and enhanced wireless security feature, ExpWave 240B is unmatched Point to Point solution in the world today. By supporting IPSec VPN (Virtual Private Network) with 3DES engine, ExpWave 240B is particularly suited for financial banks, businesses and government agencies to deploy wireless networks for most sensitive data transmission. System privacy is inherent through the MAC & 802.1x based mutual authentication functionality by preventing unauthorized intrusion to the radio link. ExpWave 240B is outdoor-mounted design to minimize the RF cable loss connecting to antenna for outdoor application and thus has outstanding performance in the longer communication distance. Supplying the power and Ethernet connectivity concurrently via a single Ethernet cable, the power over Ethernet (POE) technology makes quick outdoor installation. The optional antenna alignment kit, showing relative signal strength index (RSSI) and signal to noise ratio (SNR), is uniquely designed to aid easy antenna alignment while operating in the point to point conncection. ExpWave 240B achieves rapid return on investment (ROI) for inter-building connection compared to T1 leased line with high capacity and high data throughput. The wireless router feature can also be configured as point to two points architecture for multi-site connections as well as wireless relay function. The wireless relay function effectively assists to overcome the non-line of sight (NLOS) problem in the real environment.

1.1.1 ExpWave 240B product types

ExpWave 240B could be configured into two kinds of system topology. When operated in the point-to-point mode, one access point (AP) and one access client (AC) are needed. When operated in the point-to-two-points mode, one AP and two ACs are needed.

1.2 Physical Features of the ExpWave 240B

The ExpWave 240B is used for long-range wireless outdoor application. ExpWave 240B equips with a robust outdoor weather-proof housing. The key physical features are listed below:

Outdoor-mounted design minimizes RF cable loss connecting to antenna and thus has outstanding performance in the longer communication distance.

Power over Ethernet (POE) connection & special antenna alignment kit provide fast installation and easy operation.

1.3 Non-physical Features of the ExpWave 240B

IPSec VPN Capability

Establish a Virtual Private Network (VPN) to connect with business partners and branch offices using data encryption and the Internet to provide secure communications without the expense of leased site-to-site lines. The ExpWave VPN is based on the IPSec standard.

Packet Filtering

The packet filtering mechanism blocks unwanted traffic from entering/leaving your network.
