About
Hong Chi Association is a non-profit making organization, dedicated solely to serving people with mental handicap. To support Hong Chi in assisting the people with mental handicap to develop their potential to the full, the Department has organized a series of activities such as Christmas parties and special computer training workshops for 2 consecutive years since 2006.
The Hong Chi Little House ang Hong Chi Santa House are located at Pinehill Village, Tai Po. They are four small group homes with attractive natural scenery for children with mild grade mental handicap. In view of the needs of Internet access of the houses, we’ve started up a wireless network project in 4 phases:
Phase 1 – Investigating the possibility of setting up the wireless network at Hong Chi Children Home [4 Apr, 07]
Objectives:
-To find out the possible spots for installing wireless network equipment
-To find out any source of interference
Results:
-The laptops with wireless adaptor (802.11g) in house 2 and 4 received weak signals from the wireless access point (AP) in house 3 due to the interference of the stone walls of the houses

Phase 2 – Testing the wireless network equipments [11 Sept, 07 & 23 Nov, 07]
Objectives:
-To test the Wireless-N (draft 802.11n) router, which maintains the wireless connection up to 3 times farther than standard Wireless-G
-To test the signal expanding ability of the Wireless-G Range Expander
Results:
-The laptops with wireless adaptor (802.11n) in house 2 and 4 received nice signals from the wireless access point (AP) in house 3. However, since house 1 is far away from house 3, only weak signals can be detected
Phase 3 – Network setup 1 [28 Dec, 07]
Objectives:
-To setup the wireless network of the four houses using the Wireless-N (draft 802.11n) router and adaptors
Results:
-the performance of the Wireless-N router was not stable, house 2 and 4 receive unsteady signals
-after installing the Wireless-G Range Expander in house 4, the wireless network works nicely in house 2-4

Phase 4 – Network Setup 2 [1 Feb, 2008]
Objectives:
-To expand the wireless signal with another Wireless-G Range Expander to house 1
Results:
- All four houses can access the Internet finally!
