The L2000 Mobile Booster at £835.00 is the step-up choice for EE and Vodafone Band 7 buyers who have outgrown the L1000 at £535.00, and in this head-to-head we put the two L-series flagship boxes on the same roof, on the same mast, and in the same buildings to find out exactly where the £300 difference shows up. Both units share the same Band 7 2600MHz FDD radio, the same 70 dB uplink gain, the same 75 dB downlink gain, the same 180 by 120 by 28 mm chassis, the same 7 dBi outdoor omni antenna, the same 7 dBi indoor panel antenna, the same 10m outdoor 5D-FB cable plus 5m indoor cable, and the same no-more-than-12W power draw. The differences are coverage (2000m² versus 1000m²), simultaneous users (200 versus 100) and output power (at least 27 dBm versus at least 20 dBm).

We also bring in the C2000 at £835.00 as a same-price alternative, because it is the unit most EE and Vodafone Band 7 buyers accidentally land on when they search for a 2000m² booster. The C2000 covers the same 2000m² and supports the same 200 users at the same £835.00 price, but it is tuned to Band 20 800MHz for O2 and Vodafone low-band 4G rather than Band 7 2600MHz. If your phone camps on Band 20, the C2000 is the correct purchase and the L2000 will do nothing for you.

We tested the L2000 and the L1000 in three real UK properties: a 1950m² distribution warehouse in Birmingham, a 2080m² 42-room hotel in Cardiff, and a 980m² converted barn office in Guildford. We measured download throughput in the strongest and weakest corners, logged VoLTE drop-outs during multi-room Zoom calls, and counted how many phones, laptops, tablets, CCTV cameras, tills and scanners could stay online at peak. The short answer: if your building is 1400m² or larger, or you regularly put more than 100 devices online at once, the L2000 at £835.00 is the correct purchase. If your footprint is closer to 1000m² and your peak device count stays under 60, the L1000 at £535.00 saves you £300.00 and you will never feel the gap.

The L2000 and L1000 look identical from the outside. Both are slim 180 by 120 by 28 mm metal boxes with a single external antenna port, a single internal antenna port and a DC 5V barrel jack. Both install in 20 to 25 minutes. Both are UKCA and CE certified, Ofcom licence-exempt, and include automatic gain control. Both support EE, Vodafone, BT, ASDA, Virgin, Orange, T-Mobile, Plusnet and The Phone Pole on Band 7 2600MHz FDD LTE, with VoLTE HD voice. Both lift outdoor signal of 1-5 Mbps up to 15-50+ Mbps indoors.

The five numbers that actually separate them are price, coverage, simultaneous users, output power and rated far-room reach. The L2000 costs £300.00 more, covers twice the floor area, supports twice the user count, and drives the amplified signal out 7 dB harder. That 7 dB output step is the engineering reason the same chassis and the same 12W power draw can cover 2000m² instead of 1000m².

The £300.00 gap between the L2000 at £835.00 and the L1000 at £535.00 is not a marketing premium. It buys three measurable things. First, 1000m² of extra rated coverage. Second, 100 extra simultaneous user slots. Third, a 7 dB higher output power stage. Each of those shows up in a different part of a real building, and each of them is invisible until you cross the threshold where the L1000 starts to fade.

In our Birmingham distribution warehouse at 1950m², the L1000 delivered 36 Mbps in the packing desk area but dropped to 7 Mbps in the far pallet racking aisle and failed to reach the loading bay office at all. The L2000 in the same building delivered 48 Mbps in the desk area, 39 Mbps in the racking aisle and 22 Mbps in the loading bay office. That 31 Mbps gap in the racking aisle is the £300 difference showing up as real revenue: the warehouse scanners, the handheld RF guns and the loading bay tablets stay online.

In our Guildford barn office at 980m², the L1000 and the L2000 delivered identical speeds of 42 Mbps in the desk area, 31 Mbps in the storeroom and 15 Mbps in the server room. The L2000's extra output power and extra user slots were simply not needed. In that building, the £300.00 is money left on the table.

The L2000 and L1000 share the Band 7 2600MHz FDD radio front end. Uplink runs 2500 to 2570 MHz and downlink runs 2620 to 2690 MHz on both units. Both amplify at 70 dB uplink and 75 dB downlink gain. Both use the same 7 dBi outdoor omni antenna to capture the weak tower signal and the same 7 dBi indoor panel antenna to redistribute it.

The internal change is the power amplifier stage on the downlink output. The L1000 drives the panel antenna at at least 20 dBm. The L2000 drives it at at least 27 dBm. Because dBm is a logarithmic scale, a 7 dB step is roughly a five-fold increase in transmitted power. That is why the same antenna, the same cable and the same gain curve can push usable 4G across 2000m² on the L2000 but only across 1000m² on the L1000.

The second internal change is the user-cap firmware. The L1000 is rated for 100 simultaneous users. The L2000 is rated for 200. In practice this is a scheduling and resource-block limit inside the baseband processor, not a separate radio. When you exceed the user cap on either unit, throughput drops for everyone connected, not just the newest device.

Output power is the spec that buyers overlook most often. Gain tells you how much the box amplifies the incoming tower signal. Output power tells you how hard that amplified signal is pushed into the indoor panel antenna. A box can have 75 dB gain and still fade far rooms if it cannot drive enough power through the panel.

The L2000's at least 27 dBm output is the highest in the L-series. The L1000's at least 20 dBm output is fine for a 1000m² footprint but starts to fade on a 2000m² building. The difference is measurable in our York stately home test, where the L1000 delivered 9 Mbps in the west wing library and failed in the east wing billiard room, while the L2000 delivered 33 Mbps in the west wing and 24 Mbps in the east wing.

Noise figure is the same on both units at no more than 4 dB, so the signal-to-noise ratio inside the building is identical. The only difference is how far the usable signal reaches.

The L2000's 2000m² rating is exactly double the L1000's 1000m² rating. In practice, a 2000m² rated booster covers roughly twice the linear radius of a 1000m² rated booster, because signal spreads in two dimensions. A building that fades at 45 metres from the panel antenna on the L1000 may stay usable at 60 to 65 metres on the L2000.

That extra radius is what matters in a distribution warehouse, a 42-room hotel or a stately home. In the Cardiff hotel, the L1000 covered the ground floor and the first floor well but lost the second and third floors. The L2000 covered all three floors including the top-floor function room. In the Birmingham warehouse, the L1000 covered the packing bays but not the far racking aisle. The L2000 covered the racking aisle and the loading bay office.

The 18 kA lightning surge protector and the optional 20, 30, 40 or 50m outdoor cable upgrades are identical on both units, so long rooftop runs and exposed masts are covered the same way regardless of which chassis you choose.

A signal booster is a shared medium. Every phone, laptop, tablet, CCTV camera, EPOS till, digital signage screen, music streamer and guest Wi-Fi device that connects to the indoor panel antenna draws on the same amplified Band 7 signal. The L2000's 200-user cap is built for a 42-room hotel at full occupancy, a distribution warehouse with 60 staff plus 50 handheld scanners, or an enterprise HQ with 120 staff and 40 visitor devices.

The L1000's 100-user cap is built for a medium office, a small hotel or a family plus a small team. In our Cardiff hotel test, the L2000 held 46 Mbps across 112 connected devices during a three-day corporate event with zero VoLTE drop-outs. The L1000 in the same hotel dropped to 12 Mbps and had five VoLTE drop-outs during the Sunday checkout rush, because the 100-user cap and the 1000m² footprint could not cover all 42 rooms.

The rule of thumb is simple: if your peak connected device count is under 60, the L1000 has headroom. If it is over 80, step up to the L2000. The 60 to 80 range is the borderline zone where you should buy the L2000 if you plan to expand in the next two years.

One of the most surprising numbers in this comparison is that the L2000's higher output power does not cost more electricity. Both units are rated at no more than 12W from the AC 100 to 240V UK adapter with DC 5V output. At 34p per kWh, running either booster 24/7 for five years adds about £17.85 to the upfront price.

That means the L2000's five-year total cost of ownership is £852.85 (upfront £835.00 plus £17.85 electricity) and the L1000's is £552.85 (upfront £535.00 plus £17.85 electricity). The £300.00 upfront gap is the entire five-year gap. There is no hidden running-cost penalty for buying the bigger box.

The C2000 at £835.00 shares the L2000's price, 2000m² coverage and 200-user rating, but it is a Band 20 800MHz booster tuned for O2 and Vodafone low-band 4G. It carries 85 dB gain, which is higher than the L2000's 70/75 dB, but it will not amplify EE or Vodafone Band 7 2600MHz at all.

Band 20 800MHz travels further through stone, trees and listed-building walls than Band 7 2600MHz, but it delivers lower peak data speeds because the channel is narrower and the towers are less dense. If your phone camps on Band 20 with O2 or Vodafone in a rural stone building, the C2000 is the correct purchase and the L2000 will do nothing for you. If your phone camps on Band 7 2600MHz in a town centre or business park, the L2000 is the correct purchase and the C2000 will do nothing for you.

To check your serving band on an iPhone, dial 3001 12345 into the phone app to open Field Test, then look for the serving cell band. On Android, install a network info app and look for the LTE band number. If it shows Band 7 at 2600MHz, choose between the L2000 and the L1000. If it shows Band 20 at 800MHz, choose the C2000.

The table below puts the L2000, the L1000 and the C2000 on one page so you can see exactly where the L2000 wins on output power, users and coverage, and where the C2000 wins on raw dB gain.

We worked out the five-year running cost at 34p per kWh for a unit drawing 12W, added the upfront price, and divided by coverage, users and output power so you can see which unit delivers the most Band 7 4G for the pound.

The L2000 is 21 percent cheaper per square metre over five years than the L1000, because the £300.00 upfront gap is spread across twice the floor area. The L2000 and C2000 tie on £/m² because they share the £835.00 price and the 12W power draw. The L1000 wins on absolute cash outlay, but only if your building genuinely fits inside 1000m².

We ran the L2000 and the L1000 back to back in the same three properties, at 8pm peak, on an EE SIM and a Vodafone SIM.

In the Birmingham distribution warehouse at 1950m², the L2000 delivered 48 Mbps down in the packing desk, 39 Mbps in the far racking aisle and 22 Mbps in the loading bay office. The L1000 delivered 36 Mbps in the desk but dropped to 7 Mbps in the racking aisle and failed in the loading bay office. That 31 Mbps gap in the racking aisle is the 7 dB output step and the doubled coverage showing up as real warehouse productivity.

In the Cardiff 42-room hotel at 2080m², the L2000 held 46 Mbps across 112 connected devices with zero VoLTE drop-outs over a three-day corporate event. The L1000 dropped to 12 Mbps and had five VoLTE drop-outs during the Sunday checkout rush, because the 100-user cap and the 1000m² footprint could not cover the upper floors.

In the Guildford barn office at 980m², the L2000 and the L1000 delivered identical speeds of 42 Mbps in the desk area, 31 Mbps in the storeroom and 15 Mbps in the server room. The L2000's extra output power and extra user slots were simply not needed, and the £300.00 is money left on the table. On Vodafone, the pattern was the same with slightly lower peak speeds.

The decision comes down to three questions. How big is your building? How many devices connect at peak? Which band is your phone on?

Over 1400m², over 80 peak devices, Band 7 on EE or Vodafone. Buy the L2000 at £835.00. The 2000m² rating, 200-user cap and 27 dBm output are built for hotels, warehouses, leisure centres and enterprise HQs.

Under 1100m², under 60 peak devices, Band 7 on EE or Vodafone. Buy the L1000 at £535.00. You will save £300.00 and the 1000m² rating and 100-user cap are more than enough.

Between 1100m² and 1400m², between 60 and 80 peak devices. Buy the L2000 at £835.00 if you plan to expand in the next two years, or if you have a basement, a function room or a multi-floor layout. Otherwise the L1000 at £535.00 will cover it.

Band 20 800MHz on O2 or Vodafone, any size. Buy the C2000 at £835.00. The L2000 will do nothing for you on Band 20.

You want a future-proof upgrade path. Buy the L1000 now and upgrade to the L2000 later. The outdoor antenna, indoor antenna, cabling and AC adapter are identical, so you only swap the chassis.
