US Patent:
7826425, Nov 2, 2010
Filed:
Jul 28, 2006
Appl. No.:
11/495448
Inventors:
Ramesh Sekhar - San Jose CA, US
Assignee:
Symbol Technologies, Inc. - Holtsville NY
International Classification:
H04W 4/00
US Classification:
370331, 370338, 370332, 370390, 455574, 700275, 700 26
Abstract:
Described is a method for transmitting a voice packet from a first access point (“AP”) to a mobile unit (“MU”), forwarding the voice packet from the first AP to a second AP when acknowledgement of receipt of the voice packet is not received by the first AP and transmitting the voice packet from the second AP to the MU. Also, a system having a first access point (“AP”) transmitting a voice packet to a mobile unit (“MU”) and forwarding the voice packet when acknowledgement of receipt of the voice packet from the MU is not received by the first AP and a second AP receiving the forwarded voice packet from the first AP and transmitting the voice packet to the MU.

US Patent:
7966045, Jun 21, 2011
Filed:
Jun 9, 2008
Appl. No.:
12/135618
Inventors:
Robert Beach - Los Altos CA, US
Ramesh Sekhar - San Jose CA, US
Wanda Sealander - Bedford NH, US
Assignee:
Symbol Technologies, Inc. - Holtsville NY
International Classification:
H04B 1/16
H04B 1/38
US Classification:
455574, 4553431, 4553435
Abstract:
A wireless local area network audio and video communication system with mobile units is provided, wherein mobile units are operated in a power saving mode and become active at selected intervals corresponding to the duration of audio and video signals forming audio and video data packets. In a preferred arrangement the mobile units have a digital signal processor that operates at different clock rates during different portions of the intervals.

Loseless Roaming Via Bridging Between Access Ports

View page
US Patent:
8111676, Feb 7, 2012
Filed:
Nov 19, 2007
Appl. No.:
11/942422
Inventors:
Ramesh Sekhar - San Jose CA, US
Assignee:
Symbol Technologies, Inc. - Holtsville NY
International Classification:
H04W 4/00
US Classification:
370338, 370331, 370332, 370390, 455574, 700 26, 700275
Abstract:
In a network comprising a wireless device, a first access point (AP) and a plurality of neighbor APs, a method is provided for reducing the chances of packet loss when the wireless device roams from the first AP to one of the neighbor APs. For example, when the first AP is transmitting a particular packet of a packet stream from to the wireless device, the wireless device begins to move away from the first AP toward at least one of the neighbor APs. The first AP maintains an acknowledgement counter for the particular packet which counts a number of times the particular packet has been transmitted by the first AP without receiving an acknowledgement (ACK) message from the wireless device confirming successful reception of the particular packet from the first AP. The first AP determines whether an ACK message was received for the particular packet, and if not, the first AP determines whether the number of times the particular packet has been sent is equal to a particular number of attempts. If the first AP determines that the number of times is equal to the particular number of attempts, then the first AP forwards the particular packet to the neighbor APs.

Ramesh Sekhar - San Jose CA, US
Assignee:
Symbol Technologies, Inc. - Holtsville
International Classification:
H04W 4/00

US Classification:
370351, 370358, 370238, 455445, 4554221, 455 412
Abstract:
Described is a system comprising a first wireless device and a second wireless device. The first device has access to a packet routing table which includes data indicative of a packet transmission path in a wireless mesh communications network. The second wireless device is communicatively coupled to the first device and has access to the routing table. Upon receipt of a packet by the first device which is addressed to the second device, the first device determines, as a function of at least one of (i) the routing table and (ii) a first identifier of the second device, a second identifier of a third wireless device to receive the packet directly from the first device. At least one of the first, second and third devices updates the routing table.

Client Bridge Between Wired And Wireless Communication Networks

US Patent:
8553603, Oct 8, 2013
Filed:
Jun 9, 2011
Appl. No.:
13/156823
Inventors:
Ramesh V. Sekhar - San Jose CA, US
Assignee:
Symbol Technologies, Inc. - Holtsville NY
International Classification:
H04W 52/02
US Classification:
370311
Abstract:
A method and client bridge for bridging clients between a wired and wireless communication network includes a radio transceiver with a register and a controller for indicating to the wireless network that all wired client devices of the wired network are in Power Save Polling (PSP) mode, selecting the next wired client to be indicated as being in Continuously Awake Mode (CAM) mode, storing a Media Access Control (MAC) address of that selected client in the register, indicating to the wireless network that the selected client is in CAM mode, receiving any packets from the wireless network, which are acknowledged using the register, indicating to the wireless network that the selected client is back in PSP mode, and repeating these operations until all wired client communications are serviced.
