Citizens National Bank of Waxahachie, Texas was in dire need of serious IP bandwidth between their remote branch offices and disaster recovery site in Midlothian, Texas. Network bandwidth in this part of Texas does not come cheap and is primarily limited to T1 and/or T3 services from the local telcos. BTI was asked to evaluate the possibility of running wireless bridges between as many of Citizen’s sites as possible. The terrain in the area is sometimes difficult due to rolling hills and tall trees. After performing a path analysis, it was determined they would need a 150′ AGL tower at the Waxahachie and Midlothian locations. Citizens had the towers approved and installed providing the necessary Fresnel clearance between the two major branches.

Today, the bandwidth between the main branch in Waxahachie and the DR site in Midlothian is supported by dual RAD Airmux-400 wireless bridges running in parallel giving a full-duplex speed of approximately 90 Mbps over the 12 mile distance. The towers also provide the necessary elevation for reaching 7 additional locations throughout the CNB network. The monthly expense savings is substantial and the increased bandwidth has allowed Citizens to perform disaster recovery data backups over the network.
