As an active adviser to your wireless communications initiatives, USAT Corp. has information to share:
*IPV4 & IPV6 INFORMATION*
VZW recently announced that it will stop issuing new public static IPv4 IP addresses on June 30th 2017. USAT has analyzed how this will affect our critical infrastructure clients and an initial summary is below:
- If your organization’s communication devices are currently sending data on a Verizon private network, you will not be affected by this change.
- Any existing IPv4 public static IPs currently in use will continue to operate as usual after June 30th 2017.
- Any devices activated on the VZW network after June 30th MAY NOT be assigned an IPv4 public static IP address. USAT has received no guarantees that exceptions will be made.
IN ADDITION, PLEASE ALSO CONSIDER: that if your organization has reserved IPv4 public static IP blocks but do not have the associated IPs assigned to an active device on the VZW network, it may be in your best interest to activate them before June 30th, or VZW will have the right to reclaim those unused IPs from your organization.
Below find two statements from USAT’s key manufacturer partners about IPv6 support for their product lines post-June 30th. In both cases, the news is good:
If you have any concerns about a specific wireless gateway/router or if you are questioning whether your application requires a public static IP, please contact your USAT Corp. sales account manager or respond to this email.
*SIERRA WIRELESS FIRMWARE—IMPORTANT ACTION REQUIRED—UPGRADE TEMPLATES TO 4.7*
It is important to note that all new devices in the GX450, RV50, and ES450 product lines from Sierra Wireless are shipping from the factory with 4.7 pre-loaded. Once a device has 4.7 on it, the device cannot be downgraded to an earlier firmware. In preparation for new deployments, USAT recommends that all current users of the GX/ES and RV families upgrade an existing unit in their stock to the latest firmware and validate that all of their configurations work with their solutions.

*SIERRA WIRELESS End Of Sale (EOS) ANNOUNCEMENTS*
–All GX400s will EOS on April 30th 2017 with the last ship date set for 12/30/2017.
–The AT&T LS300 will also EOS on April 30th 2017 with the last ship date set for 12/30/2017.
–Please note the VZW LS300 is still actively in production and EOS has not yet been announced.
Do not hesitate to contact USAT with specific questions related to your business applications. Remember that we are your partners for all elements of a wireless project—including cabling, antennas and enclosures. Check out the spec sheet for the new log periodic LPDA antenna by Poynting that is making a significant difference in connectivity in fringe locations for clients using 4G only LTE Advanced network devices.
I had a front row seat on the development of a very unique MIMO 2G/3G/4G/LTE/XLTE antenna for fixed-point cellular connectivity. What has been created, and is currently in pre-production is a slim line MIMO antenna assembly that has been designed to easily fit on the top of a NEMA utility cabinet, or other type of enclosure, requiring that only one hole be drilled, not two. As I have blogged about previously, in order to optimize the speeds of an LTE antenna, there needs to be two antenna fixtures attached to the LTE router/gateway/modem. That is because LTE is a true “multiple-in-multiple out” technology and requires two fixtures to be in use simultaneously for an optimized performance. In the past, with 3G cellular network devices, I really did not advocate for the diversity antenna for every installation. In the 3G world, the addition of the diversity antenna meant a very incremental change in connectivity that was not always noticeable in real-world performance for the router or gateway. However, having seen extensive bench tests showing the differences in speeds and feeds for LTE routers using one antenna versus two antennas, the clear answer is that two antennas make very noticeable difference in performance. Below see pictures of the new antenna and how it has been carefully designed to take up very little real estate when mounted. The narrow, oblong shape of this LTE antenna allows for this antenna to mount to the top of most standard NEMA enclosures or environmental cabinets used by utility companies and other energy companies. This single device can replace the current status quo, which is mounting two “stubby” or “salt and pepper shaker” form factor antennas. This is an early look at this device, which will be made available by Mobile Mark. Once the costing has been formalized and a part number has been assigned, the antenna will be made available. For now an engineering sample can be ordered using the part number EDN324. If interested, make an inquiry here referencing that part.
Multiple-Input-Multiple-Output (MIMO) antennas solutions require two antenna fixtures and are designed for use for LTE networks built out by the public network carriers (in the USA–AT&T, Verizon). By utilizing multiple antennas, data throughput and range are increased compared to a single antenna using the same radio transmit power. Additionally MIMO antennas improve link reliability and experience less fading than a single antenna system. By transmitting multiple data streams at the same time, wireless capacity is increased.
MIMO technology uses Multipath (when wireless signals “bounce” off of objects and arrive at the receiver at different times) to improve wireless performance. MIMO technology takes a single data stream and breaks it down into several separate data streams and sends it out over multiple antennas. This provides redundancy. The receiving MIMO antenna will “look” at each stream being sent to determine the strongest one to choose.
Our company has performed bench tests where using a MIMO antenna system for LTE has increased performance by 40% over using one antenna fixture. Currently our chosen path is to use two separate antennas (that utilize the same cellular fixture) for our MIMO solutions. Examples of antennas that can be used in pairs for MIMO are below. In the near future we look forward to bench-testing MIMO antenna systems that contain both MIMO antenna fixtures in a single housing or radome.
