A communication system comprises a wireless switch, a plurality of wired access ports and a plurality of wireless access ports. The plurality of wired access ports are coupled to the wireless switch via a wired connection and are configured to receive data over the wired connection and over a wireless connection. The plurality of wireless access ports are configured to receive data over the wireless connection from the wireless access port and to send data over the wireless connection to the wired access port. The wireless access ports are further configured to receive and encapsulate first wireless data packets in to first wired data packets based on a wired transmission protocol and encapsulate the first wired data packets into second wireless data packets based on a wireless transmission protocol.
1. A communication system, comprising:
a wireless switch;
a plurality of wired access ports coupled to said wireless switch via a wired connection and configured to receive data over said wired connection and over a wireless connection; and
a plurality of wireless access ports configured to receive data over said wireless connection from the wireless access port and to send data over the wireless connection to the wired access port, the wireless access port further configured to receive and encapsulate first wireless data packets in to first wired data packets based on a wired transmission protocol and encapsulate said first wired data packets into second wireless data packets based on a wireless transmission protocol.
2. The system of claim 1 , wherein said wireless transmission protocol is an 802.11 protocol and said wired transmission protocol is an Ethernet protocol.
3. The system of claim 1 , wherein said wired access ports are configured to receive said second wireless data packets and remove said first wired data packets for transmission over said wired connection.
4. The system of claim 3 , wherein said wireless switch is configured to receive the first wired data packets, extract the first wireless data packets, and place a payload of first data packets into second wired packets for transmission outside the communication system.
5. The system of claim 4 , wherein said wireless switch is configured to remove the first wired data packets and encapsulate the first wired data packets into third wired data packets for transmission within the communication system, via said plurality of wireless access ports.
6. The method of claim 1 , wherein a mobile unit operating in the communication system is configured to directly send data to either said plurality of wireless access ports or said plurality of wired access ports.
7. The system of claim 1 , wherein said plurality of wired access ports download operational software upon boot-up from said wireless switch.
8. The system of claim 7 , wherein said plurality of wireless access ports download the operational software from said wired access ports.
9. The system of claim 8 , wherein a new wireless access port downloads operational software from one of said plurality of wireless access ports.
10. The system of claim 1 , wherein said wired connection is made using an Ethernet protocol.
11. The system of claim 1 , wherein a software update can be delivered to each of the plurality of wired access ports and each of the plurality of wireless access ports via the wireless switch.
12. The system of claim 1 , wherein each of the plurality of wireless access ports can be added to the communication system without performing a survey of the site where the communication system is located.
13. The system of claim 1 , wherein the wireless switch is a gateway to an external computer network.
14. An access port for use in a wireless local area network, comprising:
an antenna coupled to the wireless receiver;
a wireless receiver coupled to the antenna and configured to receive data packets sent over a wireless link;
a wireless transmitter coupled to the antenna and configured to transmit data packets over the wireless link; and
a processor coupled to the wireless receiver and wireless transmitter, the processor configured to:
encapsulate a first wireless data packet received by the wireless receiver into a first wired data packet using a wired data protocol; and
encapsulate the first wired data packet into a second wireless data protocol for transmission over the wireless link.
15. The access port of claim 14 , wherein the processor is further configured to:
utilize the wireless receiver to recognize a second access port that is already part of the network;
send an initialization message to the second access port; and
receive a software image to load into memory and execute using the processor.
16. The access port of claim 14 , wherein the wireless protocol is an 802.11 protocol.
17. The access port of claim 14 , wherein the wireless transmitter sends data to a wireless switch via a wired access port connected to the wireless switch with a wired connection.
18. The access port of claim 14 , wherein the antenna comprises a receiver antenna coupled to the wireless receiver and a transmit antenna coupled to the wireless transmitter.
