2.5 Wireless LAN Device
This section describes the wireless LAN BTS and mobile stations that can be connected
with OfficeServ 7030 system.
2.5.1 Wireless LAN Base Station (Basic)
The Wireless LAN Base Station (SMT-R2000) consists of both wire and wireless
processing parts. There is IEEE 802.3 Ethernet interface connected with LAN in the wire
processing part. The wireless processing part has two wireless LAN RF interfaces which
are IEEE 802.11 b/g standard with the wireless frequency band of 2.4 GHz and IEEE
802.11a standard with the wireless frequency band of 5 GHz.
Figure 2.20 SMT-R2000
The wire Ethernet interface is connected with the LAN based on 10/100 BASE-T and
transmits/receives data (e.g., Internet access). The wireless processing part
transmits/receives voice data for wireless voice calls and accesses the wireless Internet
2.5.2 Mobile Station
SMT-W5100 (Wireless IP-Phone Mobile type), which is a local wireless mobile station,
uses the wireless LAN of IEEE802.11b/g to allow the users to make voice calls.
The SMT-W5100 supports hand-over when moving between the APs (SMT-R2000) and can
use data terminals such as laptops that enable the wireless LAN in the same place.
SMT-W5100 performs the message service functions supported by OfficeServ 7030 system
as well.
