Local Telephone Lines Recovery After Swamping As a result of floods in many residential places water penetrates into the territorially-production plant cable through insulation damage and changed its electrical characteristics making dialing impossible. Authors propose a simple and economical option of cable repair.

From Cisco’s Source. All Beamforming Solutions Are Not Equal
Antenna systems beamforming solutions became an important feature
for corporate points of access of802.11n and next standards, for they
permit to optimize upward and downward data stream and also enhance network throughput. To solve this problem there are two approaches: with the help
of a patch antenna or a DSP. Both of them have certain advantages but
DSPs have many benefits that lead to higher system performance
make it a more favorable chose.
