SMS Latency is loosely defined as the amount of time it takes from when a message is submitted to an aggregator until the message is delivered to the handset. We say loosely because many companies define it more narrowly in their contracts to only include the time taken from when a message is accepted from an enterprise until it is passed onto the delivering SMSC, this is due mostly to the fact it is very difficult to guarantee latency in someone else’s network.

Location Based Services - See entry for Location Based Services (LBS).

When a message is submitted to an aggregator, the aggregator will determine the home network of the destination telephone number and the feature requirements. Based on this information the aggregator will determine which available routes could be used to deliver the message. The type of routing algorithm chosen based on this information will determine the overall reliability and cost of the message. Choosing the lowest cost option (regardless of quality or provenance) would be regarded as least cost routing and is not recommended for mission critical traffic.

When a connection is not compliant with the standard SENDXMS specifications of an SMS protocol or when it’s using another protocol (for example, HTTP, SMTP, TCP), the Operator team will develop its own proprietary software, called a LIBSPEC, specifically for that connection.

Light Fidelity (LiFi) is a wireless communication technology similar to WiFi but using visible light communication to increase bandwidth.

A range of services that are provided to mobile subscribers based on the geographical location of their handsets within their cellular network. Handsets have to be equipped with a position-location technology such as GPS to enable the geographical-trigger of service(s) being provided. LBS include driving directions, information about certain resources or destinations within current vicinity, such as restaurants, ATMs, shopping, movie theatres, and so on. LBS may also be used to track the movements and locations of people, as is being done via parent/ child monitoring services and mobile devices that target the family market.

Long codes, also known as long numbers, are full mobile telephone numbers (for example, 1408 7654321 or 447624803588) that can be used for 2-way SMS applications. They look like normal subscriber numbers but are actually virtual and are assigned to an application to ensure correct delivery of MO messages.  In the United States, these may also be referred to as 10DLCs (or 10-Digit Long Codes).  See 10DLC.

Another term for a multipart message.

A Long number (also commonly referred to as a Long Code) is a destination number that messages (SMS) are delivered to, in the format of an MSISDN. See Long Code (LC, LN).

UCS2 is 16-bit coded (unicode), the mobile should display omega sign Ω.

Low Power Wide Area Network (LPWAN) are wireless networks designed to allow long-range communication at a low data rate, reducing power and cost for transmission.

Low-Rate Wireless Personal Area Network (LR-WPAN) is a computer network used for data transmission amongst devices such as computers, telephones, tablets etc.

Long Term Evolution, marketed as 4G LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements. The standard is developed by the 3GPP (3rd Generation Partnership Project).

Long Term Evolution – Category M1 (LTE-M) is a 3GPP standard to offer IoT specific communication over the LTE network, providing cheaper modules, longer battery life, and lower connectivity fees than traditional LTE.

LTE advanced is a high-speed communication specification for mobile networks which provides enhancements to the LTE standard with extended coverage, higher throughput and lower latency. According to 3GPP - "The main new functionalities introduced in LTE-Advanced are Carrier Aggregation (CA), enhanced use of multi-antenna techniques (MIMO) and support for Relay Nodes (RN)".
