Aegis Wireless Web Tablet

Software

Can I update the Web Tablet? The Web Tablet is equipped with a utility that can update the

operating system (including applications, etc.) and BIOS. The update utility enables Aegis Systems to

provide fixes to deployed devices.

Can I save files in the Web Tablet? Yes, you can save files to the My Documents folder. Permanent

files must be saved to the optional Flash Storage folder and its subfolders. If you save files to other

folders, you will lose them if the Web Tablet depletes its battery to a full power-off state.

What are the capabilities of the Java Virtual Machine? The Web Tablet features Insignia's Jeode

platform. Jeode has been certified and is fully compliant with Sun's Personal Java 1.2 and Embedded

Java 1.0.3 specifications, which is roughly equivalent to JDK version 1.1.8. For a complete description

of the JVM, refer to Insignia's web site.

Communication

What is the communication method for the Web Tablet? The Web Tablet comes with a built-in

wireless RF Networking Module, which is compatible 802.11b routers and bridges (also known as

Access Points). It uses spread spectrum technology in the 2.4 GHz (unlicensed) frequency band. The

data transfer rate ranges from 1, 2, 5.5 to 11 Mbps. Actual wireless link performance varies depending

on the environment and the number of simultaneous users.

What is 802.11b wireless technology? The 802.11b wireless LAN systems use radios in the 2.4-GHz

frequency band - the same band used by microwave ovens. The advantages of this band are that it

provides a lot of spectrum space and does not require licensing of the radio devices. Recognizing the

critical need to support higher data-transmission rates, the Institute of Electrical and Electronics

Engineers (IEEE) 802 committee ratified the 802.11b standard in September 1999 for transmissions of

up to 11 Mbps. These radio-based standards operate within the 2.4 GHz ISM band. These frequency

bands are recognized by international regulatory agencies, such as the FCC (USA), ETSI (Europe), and

the MKK (Japan)for unlicensed radio operations.

What is an 802.11b Access Point? The 802.11b standard defines two types of equipment, a wireless

station or client (may be a PC or an Internet Appliance such as the Web tablet that is equipped with a

802.11b radio or wireless network interface card) and an access point (AP), which acts as a bridge

between the wireless and wired networks. The access point acts as the base station for the wireless

network, aggregating access for multiple wireless stations onto the wired network. Access points may

also include functions such as Dynamic Host Control Protocol (DHCP), Network Address Translation

(NAT), PPPOE registration, and Firewall functions.

Can I use any 802.11b access points or routers with the Web Tablet? Yes. The 802.11b standard

facilitates this flexibility. To ensure that security of the wireless link can be achieved, ESSID and WEP

support has to be provided by these access points and routers. Access points that have been certified to

work with the Web Tablet are the following: Ambicom (WL1100B-AR) Cisco (Aironer 350) Dlink

(DWL 1000AP, DI 713P, DI614+) Linksys (BEFW11S4, BEFW11P1) Netgear(MR314), SMC

(SMC7004WBR, SMC7004AWBR, SMC2655W)
