Psion EP10 Hand-Held Computer User Manual

• b only: forces the radio to operate in the 2.4GHz band only. The hand-held will only associate with an

Access Point (AP) that supports the DSSS data rates 1, 2, 5.5 & 11 Mbps. This mode has the lowest data

rate but yields the longest range.

• b/g only: forces the radio to operate in the 2.4 GHz band only. The EP10 will only associate with an AP

that supports the DSSS data rates 1, 2, 5.5 & 11 Mbps and OFDM data rates: 6, 9, 12, 18, 24, 36, 48,

54Mbps. This mode offers the same range as b only mode but with higher data rate of 54 Mbps when

possible

• a only: forces the radio to operate in the 5 GHz band only. The hand-held will only associate with an AP

that supports the OFDM data rates: 6, 9, 12, 18, 24, 36, 48, 54 Mbps.

2.5.4.3 11n Mode

This radio supports MIMO data rates in both 2.4 GHz and 5 G band (although it only supports single stream

operation (SISO)). This increases the maximum data rate to 65 Mbps.

• Enabled: If this option is enabled, it is activated for the band or bands that were selected in Network

type. For example, if Network Type = b only, 11n is only switched on for the 2.4GHz band.

2.5.4.4 11n – Block Ack

When 11n – Block Ack is enabled, the EP10 will not send an ACK for every packet received, but it will send

an ACK after a block of data is received. The duration of time before sending an ACK is negotiated with the

AP.

2.5.4.5 Power Save Mode

If Power Save Mode is enabled, the radio remains on continuously. The disadvantage to enabling this

option is increased power consumption. The advantage to enabling this option is instant response to

TCP/IP traffic.

It is recommended that Power Save Mode be enabled to increase battery run time. It should only be disa-

bled if the application is sensitive to timing.

2.6 The Phone

EP10s are equipped with phone capabilities as a standard option.

2.6.1 The Phone Keypad

The phone keypad provides phone services like those you may find on your cellular phone. You can use the

phone keypad provided with your EP10 to, for example, send and receive phone calls, make conference

calls, view your call history, set up speed dial numbers, etc.

2.6.1.1 Sending & Ending Phone Calls using the Phone Keypad

To display the phone keypad:

•Tap on Start>Phone icon.

Note: You can also press the [Talk] key on the EP10 keyboard to display the phone keypad providing

it has been activated. The [Talk] key is labelled with a green telephone receiver icon. Refer to

“Sending & Ending Calls using the EP10 Keyboard” on page 22 for details.
